How to install an Interior Perimeter Drain or French Drain

- If the walls are wet or there are visible, leaking cracks in the wall and gallons of water
accumulate on the floor, or there is a high water table or hydrualic pressure and water comes up through cracks in
the basement floor, consider installing an interior perimiter drain and sump pit.
(In high water table situations, consider an additional drain tile across the basement as well as
around the perimeter-possibly another sump pump)

Alternative - (For water leaking through walls, not for high water table situations)
Cut a 2” notch along all outside walls (Use a diamond blade and lots of water to keep down the dust!)
The notch is drained into a sump pit or floor drain.
Cover the floor with Platon, dimples down, with a 4” lip up the outside walls (the notch is
covered as well). Install an OSB or plywood subfloor (see flooring section).
Install Platon on the outside walls, sealing the top edge with the Platon Speedstrip and tucking
the lower edge behind the 4” lip. Seal the opening between the Platon lip to the wall Platon with
duct tape.
Frame the walls on top of the Platon subfloor.
Step 1 - Break out a 16” wide strip of the
concrete floor around the perimeter of the
basement to expose the footing and soil under
the slab.
Step 2 - If you don’t have an existing one,
install a sump pit and pump beside an outside
wall. The pump should discharge at least 10’
from the house.
Step 3 - Dig a trench beside the footing, install
4” perforated drain tile and cover with crushed
stone level with the top of the footing.
Step 4 - Install Platon, dimples toward the wall,
along the outside walls, using the Platon
Speedstrip to seal the top edge. Drape the
lower edge over the footing and drain tile.
Crease the Platon at the footing to insure a
good fit.
Step 5 - Pour new concrete to replace that
which was removed.
Step 6 - Install a Platon subfloor and frame on
top of the subfloor.
