Waterproof Fish Tanks

We at industrial polymers are frequently asked to formulate coatings for containment and waterproofing. Here is an example of a large Koi Carp breeding tank located on a farm in the United Kingdom. The concrete block provides a surface which allows algae and bacteria to grow beneath the surface and is prone to cracking and leakage over time. Our Speedliner spray-on truck bed liner product was used on this project. Speedliner worked well for this application because it provides a thick rubber coating which bonds well to concrete surfaces.

It also has enough flexibility to move with the Tank as it settles and cracks from the weight of water and changes in atmospheric temperatures over the seasons. Speedliner provides an easy to clean Nonabsorbent colored liner over the concrete block and mortar. When mixed Speedliner changes from a liquid into a paste like consistency which enables it to be applied onto vertical surfaces in high thickness without sagging or running. Speedliner can be used only in fresh or saltwater applications; it cannot be used in chlorinated swimming pools. While some of our customers routinely use Speedliner in the construction of fish holding tanks we strongly recommend you allow Speedliner time to fully cure before installing your fish and test the water before use.
