Liquid Rubber, Tank Waterproofing June 3 2015

Article: Liquid Rubber - Tank Waterproofing. Killam, Alberta. Oil and Gas. Industrial.

Liquid rubber is a product that we use extensively on commercial and industrial metal roof systems and gutters to waterproof them from rain and ice damming.

Liquid rubber can also be used to waterproof foundations, canals, ponds, tanks, RV's, gutters, pipelines, park structures and has numerous other residential, commercial and industrial applications. Mining, oil and gas, marine and agricultural applications are numerous.

There are various grades of liquid rubber and it can be rolled, brushed or sprayed on.

This field report is from our liquid rubber crew that were waterproofing tanks at an oil and gas facility in Alberta.

For more information visit our main web site page on liquid rubber.

May 11, 2015: Liquid Rubber Waterproofing Crew Attends to Site. 930 am arrive on site. We started on tank one. One part of the crew started shoveling out the sand which was 2 feet deep in spots and preparing the tank and outer ring for rubber. Once they had the sand shoveled back and the entire outer ring exposed we the then cleaned it with wire brushes and cleaner - this process took the crew until 3 pm. At 3 pm we started to lay in the scrim sheet and apply liquid rubber to the tank and outer ring. This process took the crew to 5:30 pm. The other portion of the crew did the inside portion of the tank - the containment section of the tank. We had to clean all the dirt up and then began scrubbing the floors and around the penetrations and perimeter. This portion of the work was done at 130 pm. Once the containment area was clean we applied seam tape along the perimeter and around all penetrations. We also had to seal off the two corners using scrim sheet and liquid rubber. After that was done we used 3 ft x 1.5 ft strips of scrim sheet to seal the tank to the concrete floor. We then coated the entire floor and applied the coating up the walls one foot. This portion of the work scope was done at 430 pm. We then helped the other part of our crew finish the outer section of the tank The site is now 50% complete and will be finished tomorrow. Man hours on cleaning and prep scope so far is 19 man hours. Man hours logged on site in total today - 46 man hours with drive time Material used 2 pails of Liquid Rubber. 1/2 roll of 3 feet mesh. 1 box of rags. 1 gallon of cleaner. 4 brushes.

May 12, 2015: Crew attends for second day of work on site.

8 am arrive on site.

We started with prepping the outer portion of the tank and ring by cleaning the tank with cleaner and outer ring as well. There wasn't extensive prep time for this - it looked like someone did half of it for us (the cleaning wasn't in our original scope so our client likely had staff attend to this). After it was all prepped the crew sealed the tank to the outer ring with scrim sheet and then coated it with liquid rubber.

We then focused on the inner part of the tank and containment enclosure. We vacuumed the dirt and scrubbed the floor and tank. After that we used 6 inch and four inch seam tape to seal in all the penetrations and perimeter of enclosure (which isn't easy - it's really tight quarters).

After the seam tape was done we then vacuumed again. Once the area was clean we used scrimmage sheets to seal the tank to the concrete foundation essentially creating a tub. We then coated everything with brush.  The customer very satisfied with finally having a solution and our work.

3rd tank. At first our customer put the 3rd tank off and said they weren't doing it, but now they want it done and they estimate that it will be ready for next Thursday.

Total man hours for prep and cleaning was 31 hours.

Total hours spent on site including drive time 78 hours.

Material used today. 3 pails of LR 1 roll of scrim sheet 3 feet long. 1 roll of 6 inch scrim sheet. 1 roll of 6 inch seam tape. 1 roll of 4 inch seam tape. 1 box of rags. 2 gallon of splice wash. 8 paint brushes.

May 22, 2015: Crew Re-attends for Scope of Work on Tank 3. 

Scope of work for third tank:
  1. Clean tank and outer ring to white glove state apply LR and mesh to seal tank to outer ring.
  2. Inner containment area. Clean tank and floor seal the floor to tank and up wall of containment area
Man hours 40 with drive time Materials 1 roll of 3ft mesh 2 pails of LR brush grade Rags 1 gallon of splice wash 4 brushes

6:30 am left Edmonton. 9 am arrive on site. We started the first part of the crew on the inner containment area. We started by cleaning the area with splice wash. Once it was clean we then used seam tape to seal in the perimeter and used mesh to seal in tank to the concrete footing. Once that was complete we then coated it with Liquid Rubber.

The second part of the crew then focused on the the outer tank and ring. We cleaned it and shoveled out some dirt in areas to make it level. We then used 3 foot pieces of mesh to seal the outer ring to the tank. As we were applying our Liquid Rubber at 2:30 the other part of the crew came to help us out and finish this tank. It was 2 x the size of the other tanks so the outer portion took a bit longer.

PVC Roof Repair Edmonton, June 1, 2015.

Article: PVC Roof Repair Edmonton, Alberta. Flat Roof. Industrial. Single Ply Membrane. DecTec.

One material available to flat roof (low slope) owners is the single ply PVC roof membrane. The roof report below is specifically a DecTec type of PVC. PVC is an acronym for Poly Vinyl Chloride. PVC roofing is a single ply membrane. There are three different single ply roof membranes typically used in the market. One is PVC, the other is TPO (or thermal plastic polyolefin) and the other is EPDM (ethylene propylene diene terpolymer). PVC and TPO are welded with hot air welders (which would be different than using a torch when installing 2 ply torch-on SBS modified). EPDM seams are not welded using a hot air welder - EPDM is seamed with adhesive. PVC, TPO and EPDM are available in different colors but typically PVC and TPO are installed white and EPDM black. In all three instances (with PVC, TPO and EPDM) the roof membrane is attached to the roof assembly in one of three ways:
  1. Fully adhered. Fully adhering a roof membrane is the process of using a specialized adhesive to adhere the roof to the substrate or roof assembly. We typically install a residential home this way because it is lighter than ballast.
  2. Mechanically fastening means that the roofing contractor is installing the membrane with fasteners. Mechanically fastening a system is faster and less expensive than fully adhering it but we tend not to choose this method.
  3. And finally there are ballasted roof systems. A singly ply ballasted roof is typically one where the membrane is loose laid (seams are either welded or adhered) and then a smooth rock is then installed on top of the membrane to ballast it. Fully ballasted systems are less expensive and quicker to install than fully adhering the membrane, however, when possible we choose to fully adhere the system. After install service is more difficult and more costly with ballasted roofing because it takes considerable time to locate and repair leaks with ballast covering the membrane.
Visit our main website for an explanation for flat roofing membrane options and descriptions of each. Below is a short roof report from one of our single ply crews doing repair work for an industrial customer that calls us out regularly. February 19, 2015: Crew Arrives at Industrial Location to Complete Repairs to PVC Flat Roof. 
Site address: 1755 Railway Street Edmonton, AB.
Today we had to roof in one roof curb with DecTec PVC. The curb was 18 inches x 40 inches. We had to wrap it with PVC and weld in 4 corners. The only issue we had today was the amount of melting snow. We were repairing and working on a down slope portion of the roof. The melting water was continually running in to our repair of the membrane laps, but we managed to get the membrane dry enough to weld.

Engineered Liquid Rubber Roof Recovery in Edmonton AB, October 2014

Below you will find a quotation, project manager notes, and a field report for an engineered liquid rubber roof recovery for an industrial metal roofing client in Edmonton, Alberta. Quotation, October 15 2014:
  • Engineered liquid rubber recovery to complete metal roof.
  • Pressure washing to clean, water test, and assess.
  • Fasteners will be tested and replaced as required to complete the roof deck, penetrations, and gutters.
  • Sheet metal repair and penetration saddle fabrication as required.
  • Remove old caulking as required.
  • Hand trowel all penetrations, roof to wall connections, fasteners, ridge, horizontal sheet seams, hidden gutters, and roof edge at external gutters with mesh and high grade rubber as required.
  • Apply liquid rubber coating, allow cure time, repeat hand trowel process above, and apply second coat of liquid rubber.
  • Liquid rubber to full inside face of parapet and top of parapet cap.
  • Ten year manufacturer warranty is extendable to twenty year maintenance agreement.
Project Manager Notes This roof structure may be a candidate for either a repair-maintenance program or an engineered liquid rubber coating - you may not have to replace it. I would not recommend a standard reflective elastomeric coating, or the SPF spray foam (with standard reflective coating), as this standard does not last well in a Western Canadian climate. Liquid rubber performs well in our climate as it has up to a 1200% expansion/contraction rate. If considering SPF for R-value, we strongly suggest covering the spray foam with liquid rubber or EPDM. Our crews do this work everyday with success. Generally speaking, metal roof systems are constant aggravating roof structures. Industrial systems have a deficient design - they are water-shedding, and not waterproofing, coverings. Metal expands and contracts more than any other roofing material and tend to leak from ice/snow loads. Leaks are also intermittent at seams (vertically where sheets are seamed together and horizontally where seams meet between sheets), penetrations, fasteners, around the perimeters at gutters, under the eaves, and at joints between roof and wall connections. Rust and corrosion may also develop. Traditional caulking or coating lasts a few seasons at best. Remedies are either spot repairs - maintenance with caulking or engineered coatings. Our recommendation in this instance is a high and engineered 2-ply liquid rubber polymer coating with a 10 year warranty, with the option of a 20 year maintenance contract for extended leak protection. Our client approved the quotation the same day for a roof recovery. Field Report, October 22 2014: After picking up the liquid rubber, we went to the work site and prepared the roof with seam tape around all seam tapes and penetrations. We then began coating the roof with liquid rubber and completed this site by the evening.

Tar and Gravel Roofing Repair, September 2014, Fort Saskatchewan

This very brief report shows that there's no job too small for GRS to handle. This industrial client's tar and gravel roof had split in a couple of places, requiring a technician to go on-site for a half day's work repairing it with meshing and sopramastic.   Roof Report: Sept 23, 2014 The technician arrived on site for 10:45 to repair the roof. They fixed a split seam (approximately 30 ft. long) on this tar and gravel roofing system, as well as some other spots along the one end of the split. In addition to the primary split addressed first, there was another split the width of the roof; perpendicular to the other one. This split required spudding before the repairs could be completed. Using 6" meshing and sopramastic, the repairs were carried out in less than five hours, leaving the technician opportunity to depart the site around 3:00pm.     Materials Used:
  • 3 Cans of sopramastic
  • 1 Roll of 6" mesh tape

Nisku Temporary Industrial Roof Repairs, July 2014

This client in Nisku, Alberta was experiencing leaking above the second floor of their office. A quotation was provided to the client with options for full roof replacement or temporary spot repairs. This report outlines the repair process. Inspection, July 29, 2014: The client is experiencing leaks from units on the roof as well as from three big hood vents coming through the wall. The caulking has deteriorated and would need be removed and resealed. They should then be meshed in on the sides. There are 6 units and 10 penetrations on the roof and the client would like them sealed with mesh and liquid rubber. This job would require approximately 40-50 man hours to complete. 20140729_093730 20140729_093732 20140729_093742 20140729_093743 20140729_093807 20140725_142835 20140725_142846 20140725_142905 Roof Report, August 6, 2014: Today we had to remove the old caulking from the hood vents as well as from areas around the units. After this we cleaned them thoroughly, applied seam tape, and then applied two coats of liquid rubber. With regards to the hood vents, we removed all old silicone and applied new caulking, then sealed in the sides with seam tape and liquid rubber. I also sealed in the caulking with liquid rubber for extra protection. The vents and penetrations are now sealed and this site is complete.
Material Used:
  • 1.5 pails of brush grade LR.
  • 3 rolls of seam tape.
  • 5 tubes of caulking.

Engineered Liquid Rubber Metal Roof Recovery Ponoka Alberta, May 2014

Below you will find a series of reports from scope of work to completion for a large industrial metal roofing coating project. The Ponoka roofing repair crew provided the following assessment: Scope of Work, May 12 2014: The metal roof will be completed using two-ply engineered liquid rubber recovery. A pressure wash will be used to cleaning, water testing, and for site assessment. Test and replace fasteners as required to complete roof deck, penetrations, and gutters. We will provide sheet metal repair and penetration saddle fabrication as required, as well as remove old caulking. All:
  • Penetrations
  • Roof-to-wall connections
  • Fasteners
  • Ridge, horizontal sheet seams
  • Hidden gutters, and roof edging at external gutters
will be hand-troweled using mesh and high grade rubber as required. Liquid rubber coating will then be applied, allowing a cure time, followed by a repeated hand trowel process as above. This will be followed by a second coat of liquid rubber. The project manager provided a rationale for using engineered coating as well. Although the industrial standard would have been to recommend reflective elastomeric coating or SPF spray foam, they do not have longevity in a Western Canadian climate. Liquid rubber, on the other hand, has been shown to have a 1200% expansion and contraction rate. The idea was to get the "most mileage" out of the metal roofing, which have a high maintenance turnover due to leaks caused by expansion and contraction of the metal. Expenses also increase with wear and tear caused by corrosion. Using high end engineered liquid rubber polymer in this climate and context would skirt many of these ongoing maintenance problems.

Leduc Industrial Metal Roof Maintenance, June 2014

This industrial client in Leduc, Alberta was provided with a quotation for various roofing options. Included were options for full metal roof replacement, roof recovery, and liquid rubber maintenance. This report follows the liquid rubber maintenance that was carried out to prevent further leaking. Inspection, June 10, 2014: There is leaking where the old building meets the new building on this site. There is a gutter which separates the 2 roofs and the leak is in the gutter. Ply’s in the gutter have deteriorated and the screws have popped through the ply’s. The original building has a sloped cladding roof which had the gutter originally, then they built the new building which is higher than the old building. The gutter between joins the two buildings.
Materials Required:
  • 2 pails of liquid rubber.
  • 1 pail of trowel grade liquid rubber.
  • 3 tubes of caulking.

By the end of the day we had most of the units done and the ridge cap complete. I would say the job is about 60% finished. Tomorrow we will finish the gutters and fasteners. 20140618_084552_resized 20140618_090443_resized 20140618_101039_resized 20140618_101051_resized 20140618_101233_resized 20140618_120719_resized 20140618_120726_resized 20140618_140909_resized 20140618_142519_resized 20140618_142529_resized20140618_152045_resized20140618_152106_resized20140618_152120_resized20140618_152138_resized20140618_170236_resized20140618_170244_resized20140618_170250_resized20140618_170304_resized20140618_170327_resized20140618_170327_resized_120140618_170346_resized20140618_170357_resized Roof Report, June 20, 2014: Today we finished all of the units and the detailing. After that I had a new hire start the fasteners while the rest of us worked on the gutters. This was a big job as we had to coat and line the whole thing with LR and cloth, then apply a second coat of LR afterwards.
We helped finish the fasteners and the roof was complete. I had the customer come up to the roof and do a walk through and he was happy with the work. This site is 100% done.
Material Used:
  • 5 pails of LR brush grade.
  • 1 pail of trowel grade.
  • 2 rolls of 6 inch x 100 ft. mesh.
  • 6 paint brushes.
  • 2 rollers.

This product is the first product we have had as roofers that solves metal roof issues and has been extremely successful with considerable and complicated roof systems for a number of our Fortune 500 or multi-national clients.
June 13 2012: We stopped by the shop en route to pick up a trowel, caulking, and wet dry gum (plastic cement) in case the leak was able to be fixed immediately upon inspection. On-site, the client lead us to the leak site where tiles were becoming stained. Visible sagging was noted. After removing the stained ceiling tile, it appeared that the leak was coming in around the RTU unit directly above someone's desk in the southwest corner of the top floor. Upon roof inspection, it was clear to me that the problem area was the plumbing vent in-between the exhaust fan and the RTU unit. It had previously been patched with plastic cement as a temporary solution. There are also a few other areas which could potentially leak in the future; a few gas line penetrations, gum cups around guy wire penetrations for antennae on the roof, and a few flashing issues around exhaust fans.

  • Gutter replacement: supply and install industrial fabricated gutter system to the entire building
Quotation, August 2 2012:
  • Roof repair and maintenance overhaul: remove gravel, wash, repair, return gravel
  • Complete roof replacement options: Spray foam (SPF), EPDM, 2-ply SBS modified bitumen (torch-on), 4-ply engineered liquid rubber roof, TOUGH ROOF
  • Roof recovery options: Spray foam (SPF), 2-ply SBS modified bitumen (torch-on), 1-ply coat tar, 2-ply engineered liquid rubber
Field Observations On this tar and gravel roof, piles are exposed and deteriorating; there are soft spots throughout the roof. There are multiple buckles and blisters. Previous contractors have attempted to stop the leak by caulking and using tar, but this is not working. The roof also has several areas where there is no gravel and has severe damage. The vents and flashing need to be resealed. The exposed bitumen in one area has severe lap splitting. I recommend that the roof be replaced or a recovery system be installed. In the event of a recovery, some areas may require replacement of insulation. The roof is approximately 35 years old and mostly like past the point of repairs. -insert sat photos- Work commenced at this site on August 23 2013 due to rainstorms. Field Report, August 23 2012: Gravel was shoveled away to clear a 40 ft. square, where one leak was found in the roof membrane. The origin was traced to another 10 ft. segment, which was torn up. After removing the old membrane, 2-ply flam flam and cap was torched down. The edges of this fixture were gummed to ensure water tightness. All the metal was then removed from units which contained it and inspected for leaks. It was reinstalled after finding no leaks underneath. Afterwards, six gum boxes were filled and the gravel which had been swept away from the problem area was replaced. IMG_3875 IMG_7136 IMG_7167 IMG_7845 IMG_9253   Flat Roof Scope, September 12 2013: The client has approved a 2-ply torch-on roof recovery. We will cut out wet spots. Metal capping has to be saved, as the client does not want to pay for brand new capping. We will not be providing cranes for this site, use jack units if you have to. The metal roof will also need a liquid rubber application. Materials
  • 24x 205 L drums of MetalSafe B-300
  • 24x 18.9 L pails of MetalSafe S-300
  • 15x 18.9 L pails of TrowelGrade B-400
September 19 2013: After making a supply run, we arrived to the site at 2:00 pm. The existing gutter system was measured and called in to get a price quotation for new gutters. September 23 2013: We finished tearing off the existing system and kept torching cap sheet on. A propane refill will be required soon (2x 50 lb. tanks). A bin was also dropped off on-site for waste removal. September 26 2013: Cap metal was measured for the flat roof and we sent in an order for materials. Overhanging cap sheeting was also cut back to a proper size. Liquid rubber preparation work has also begun. Once metal fabrication is completed, we will begin gutter replacement. October 9 2013: New hires were tasked with adding polyurethane to the window sidings and complete roof sheeting. A large part of the morning was spent troubleshooting the liquid rubber machine, but we managed to finish application before the day was finished. We scheduled gutter installation with the client in December. Materials:
  • 4x rolls of SBS cap
  • 4x tubes of SOPRAMASTIC, caulking-style
  • 2x caulking guns

It was a bit slow going since this was his first time doing so with gutters. Two other crew members installed gutter hangers. In the afternoon, the newly built gutter caps and one downpipe were installed. 20131211_163333 20131211_163342 20131211_163355 20131211_163409 20131211_164503   December 13 2013: A large section was ice was removed to install a piece of industrial guttering with attached end caps. We then added hangers and fixed some deficiencies that arose with previously installed gutters and hangars. Two more crew members arrived a couple of hours later and installed gutter downspouts. While they were at it, problematic gutter attachments were dealt with. By the end of the day, all hangars and end caps were completed. Four downspouts remain as well as a small gutter section at the entrance which requires an assessment. 20131213_152531 20131213_152536 20131213_152540 20131213_155034 yimg-1109407680-101-685963814 yimg-1109407680-101--1584029527 December 18 2013: image (1) image (2) image (3) image (4) image (5) image (6) image (7) image (8) image (9) image (10) image (11) image (12) image (13) image December 19 2013: 20131219_092739 20131219_092756 20131219_092806 20131219_092835 20131219_092842 20131219_092847 20131219_092909 20131219_093002 20131219_093546 20131219_093553 20131219_093612 20131219_094323 20131219_094905 20131219_095148 20131219_095155 20131219_095830 20131219_095900 20131219_100031 20131219_100641 20131219_100647 January 2 2014: We were called back for another gutter inspection. Most of the seams are leaking in from the west side of the building and east of the client's main office. The gutter installation job was done in very cold weather, which could be the reason for the leaks. The caulking was probably not well applied. We should review all of the seams for further leaks. 20140102_161544 20140102_161620 20140102_161743 20140102_161750  20140102_161816  20140102_161851  20140102_162058 20140102_161544 20140102_161620  20140102_161750    20140102_161851 20140102_161914 20140102_162058 20140102_162525 20140102_162601 20140102_162616 20140102_162659 20140102_162715 20140102_162739 20140102_162809 20140102_162827 20140102_162849  20140102_162916 20140102_162935  20140102_174714 January 21 2014: Firstly, all ice was removed around the affected unit. Detail patches were torched onto the unit corner, and we re-gummed a gum box. There was a piece of cap that was torched a quarter of the way; the rest had peeled off the affected unit. We dried the peeling and torched it back into place. This was probably the main cause of the office leak. Afterwards, five more soft gum boxes were touched up. A skeleton crew was left behind for firewatch at the end of the day.   20140121_093936 20140121_105608 20140121_122326 20140121_125637 20140121_130513 20140121_135350 20140121_135358 20140121_135411 20140121_135810 20140121_135821 20140121_135834 20140121_155128   < End Report > Code: 130 Contact Us Call our 24 hour emergency roof repair at 1.780.424.7663.

Edmonton Industrial Grade Roof Gutter Install, December 2013

This commercial client in Edmonton required a gutter installation on their metal rooftop. A GRS crew was dispatched to complete the work; this report outlines part of the installation and includes photos of the site. Roof Report, December 20, 2013: We set up the scaffolding but first had to dig out ice so that we had an area to put the scaffold. Then we put up 2 pieces of gutter (caulked and sealed) but can't put up anymore because a truck is parked in the way. We have to pick up and move the scaffolding by hand due to the ice (we cannot use wheels).
The riveting and 2 downspouts are done on the portion that we have up, unfortunately the truck is still blocking us from doing more. We had to break 6-8 inches of ice every 4 feet for scaffolding and downspouts. We cleaned up the site before leaving.
