StormTrap, the precast concrete modular storm water detention system, is custom designed to meet each site’s unique characteristics. Its SingleTrap design exceeds HS-20 loading with 6 in. of cover, making it ideal for projects with limited rim to invert elevations. SingleTrap units are customizable in 1-in. increments from 1 ft 2 in. to 5 ft in height. The system can be set on customizable strip footings with stone aggregate that allows water to recharge back into the soil.
