Gas-tight foam basins for sewage applications
TOPP Industries
The Evolution E-Series Basin (photo) is a maximum-durability structural foam basin that is resistant to cracks and dents. The E-Series features self-tapping lags for cover attachments and 180-deg dual, raised flat pockets for a tight inlet seal. All basins are gas-tight for sewage and radon-mitigation applications. E-Series basins are available in diameters up to 30 in., with foam covers up to 24 in. Additionally, epoxy-coated steel and non-skid fiberglass covers are available. The basins can accommodate 4-in. composite inlet hubs and require no external stacking ribs that may interfere with the use of external filtration configurations.
