Draintile Systems Installs & Repairs

Outside Draintile System

For water seeping through walls, either concrete block or poured concrete, the better method is to install a draintile/gravel filter system on the outside of the structure. Installing the system involves digging a trench down to the bottom of the footing. After the wall has been thoroughly scraped, a thick coating (approximately 3/16”) of Elastomeric liquid waterproofing membrane and Miradrain applied with a trowel. It is then covered with a sheet of four mil rubber membrane for an extra layer of protection. A four-inch perforated pipe (draintile) is laid at the proper footing location and covered with at least two feet of clean, washed gravel. The remainder of the trench is backfilled with soil. The gravel filter is protected from intrusion of the soil backfill by an intervening layer of straw. This type of system will effectively intercept any water coming toward the wall.
