Under Slab

Application Description:

Use of a working or mud slab application offers many design and construction challenges to protect the structure from moisture invasion. J•DRAIN drainage composites are designed to guide the water from within the top slab and the working or mud slab eliminating the potential penetration of moisture into the structure.

J•DRAIN drainage composites are engineered to be installed on the working or mud slab to reduce hydrostatic pressure while efficiently channeling the water away. The three dimensional core creates a high compressive strength and high flow capacity drainage channel and the heat fused filter fabric prevents soil intrusion into the flow channel. The use of a J•DRAIN drainage composite shortens the construction process offering a cost savings.
