Calculating CULTEC Chambers For Residential Drainage

CULTEC, Inc.’s chambers may used in residential applications to control rainwater collected from gutters and/or catch basins. The chambers collect and store the stormwater underground until the soil is able to accept it back into the ground. Puddles and saturated soil are eliminated as water is diverted into the chamber and recharged into the ground. CULTEC chambers are lightweight and easily transported by hand making them ideal to install in tight areas or where minimal site disturbance is desired.
