Drain Mains Basement System is our rugged stand-alone footer system – offers superior protection against basement water seepage in one easy installation. Drain Main’s innovational design incorporates the subfloor system with wall drainage. Water enters the system through the wholes tapped into the base of the walls and flows through the Drain Main Basement System to the sump pump.

Open Back Never Restricts Water

Drain Main’s open back design allows water to enter the system for the full length of the channel. Other systems restrict water intake to holes punched in the back.

Bone Dry Cement Seams

Drain Main’s front toe channel collects water directly under concrete seam keeping the seam bone dry after installation.

Catches Water From The Face Of The Wall

The 3 ridged spacers along the backside fin of the Drain Main System catches water that may come down the wall from a crack or window well.

Drain Main Installation

  • The floor has to be a minimum of 3 1/2 inches thick over the footing.
  • Start by installing the sump pump system first. This will help manage water flow during the process of breaking out the concrete along where the floor and walls meet.
  • Beginning at the sump pump, remove concrete floor away from the wall approximately 6 inches wide and all the way down to the footer.
  • Set a short section of the Drain Main on the footer and verify that the vertical portion of the Drain Main will stick up above the floor surface a quarter inch to 1-inch after the cement work is finished. If needed some fine rock can be poured over the footing to raise the Drain Main System to achieve the right height.
  • Continue laying out the Drain Main System using the pre-molded corners and sump drop kit until you have a continuous conduit along the open trench.
  • Seems between the main sections should be covered with 3M vinyl duct tape to keep concrete from getting into the system while pouring concrete.
  • Once the system is completely laid out and seems taped, pour pea rock into the trench, filling up to the horizontal plane of the top of the Drain Main System. This will leave adequate space to pour several inches of concrete yet over the channel allowing for the back fin to stick up above the concrete and catch any water that may come down the wall through cracks or window wells.
