Uni-Cast™Concrete Underdrain

The Uni-Cast™ system is a concrete monolithic cast in place underdrain with open plenum design providing a low headloss profile with optional access beneath the nozzles. The open plenum design provides for uniform distribution at high rates of air and water during backwash and can be designed for media retaining or support gravel applications. With either a three inch or six inch slab option depending on the strength and integrity of design. The Uni-Cast™ underdrain is the most robust underdrain on the market with the strongest resistance to uplift in the industry.
