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.

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.

May 22, 2015: Crew Re-attends for Scope of Work on Tank 3.Scope of work for third tank:
- Clean tank and outer ring to white glove state apply LR and mesh to seal tank to outer ring.
- Inner containment area. Clean tank and floor seal the floor to tank and up wall of containment area
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.Other Photos:
