Bedding Slurry Installation Method

If the installation bracket or suspended installation method is not practical to use, you may install the PolyDrain channels using concrete bedding slurry (slump equals 1 to 2 inches). A minimum concrete thickness of 4" around the channel is required for this method as with all other types of installations.

Place patties of stiff concrete under the "Red Dot" Lock Block locations. Lay the channels in the bedding slurry and consolidate concrete above the anchoring rib on each side of the channel. Check alignment and grade of the channel before the concrete stiffens.

Adjust the channel, sliding it forward or backward, to insure a tight connection between the tongue and groove butt joints at the channel ends. Seal joints with appropriate sealant if required. Install precautions for cold joints. Once channels are locked into position and the bedding slurry has set, concrete can be placed to finish grade. Do not chute concrete directly against channel walls.
