You may have a retention tank in your building project to help reduce overload on your local stormwater system and also to gain LEED points. As these tanks are below grade, after construction it is very difficult and expensive to go back and do repairs, or to reapply coatings and membranes. Potable water tanks are often above ground and more accessible, but they are large and expensive to repair. Hycrete waterproofing solutions can help you in a number of ways. The waterproofing is inside the concrete ï¿½ it is protected by the concrete, and it will not get damaged or wash away over time. Unlike membranes and coatings, it does not have to be reapplied. As green, Cradle-to-Cradleï¿½, the waterproofing will not harm the water in any way and is safe for drinking water. And hydrophobic waterproofing with Hycrete solutions can help extend the life of the structure: as well as waterproofing the concrete, they increase the durability by protecting against corrosion, which would reduce the life of your tank and require expensive repair.
