GET IT RIGHT THE FIRST TIME!

That is a phrase I often used to tease my coworkers after we would finish a task. It was an inside joke. However, the phrase applies to drain tile. You generally only have ONE chance to put it in. It gets buried deeply. It can clog up if not installed right. It's expensive to redo. For these and several other reasons, you need a quality installation.

I always like to install the drain tile on the side of the foundation footer. Many builders simply install it on top of the footer. Installing the draintile on top of the footer means that your water table will be at the top of the footer. My method puts the water table about 6 inches below the top of the footer. You want the level of water as low as possible.

I recommend that the drain tile be installed the day after the footers are poured. I used to help strip the forms and then put a 1 to 2 inch layer of 1 inch gravel along side the outside of the footer. I would then install the drain tile continuously around the footer. Finally we would cover the drain tile with 1 inch gravel flush with the top of the footer. This would complete phase one of the operation.

There are advantages to doing the job this way. First, the space between the side of the footer and the wall can fill with collapsed dirt and/or concrete overflow from pouring the foundation wall. This stuff is tough to dig out and remove once the basement walls are poured. Besides, it is tough to work in the narrow area left along the foundation after the walls are up and poured.

Once the foundation is waterproofed, you can continue the drain tile installation. I recommend that you install an additional 2 to 3 feet of 1 inch gravel cover above the footer. On top of this, install tar paper or a 6 inch thick layer of straw before installing any backfill dirt.

The elimination of the straw or tar paper is a huge mistake. The backfill dirt is fluffed up. When it gets wet, small silt particles will be carried into the gravel. This will clog the gravel. If your soil has enough fine particles, you may clog your draintile! All of your work will have been for naught!  Call The Waterproof Advantage for an affordable drain tile system.
