CONCRETE POUR AND SCREEDING

Proceed with the concrete pour, filling the footing form

with concrete . Screed off the top of the lineals upon

completion. The system is left permanently in place to

act as the foundation drainage and radon reduction

system. DO NOT REMOVE FORM-A-DRAIN!

TIP: To make sure lineals stay tight against the footing

after the concrete pour and prior to backfilling, drywall

screws can be used as anchors. Simply screw them

partially into the inner (unslotted) surface of the lineals

at regular intervals prior to the concrete pour.

DRAINAGE

Drainage outlets can be created in two ways:

1. Outlet fittings – Use when the outlets are located at a

transition point between lineals.

2. Outlet adaptors (AD004) – Use when the outlet must

be positioned somewhere along the length of the

lineal, rather than at a transition point. Install with

outlet positioned at bottom of lineal, by cutting a

hole in the lineal using a 3-1/2" standard hole saw

with a pilot bit and insert adaptor.

Crossovers connecting inner and outer lineals to

facilitate drainage can be made by connecting outlet

fittings or adaptors with corrugated pipe.

Another option is to use 2", 3", or 4" PVC pipe:

Cut the correct size holes in the lineals, and cut the

ends of the connecting pipe at an angle to keep pipe

ends from blocking flow

into lineals after pipe

is inserted. Drainage

disposal must comply

with local codes and

practices. (See “Form-

A-Drain Inspector

Guide” on Page 7

information.)
