Open back design never restricts water intake, unlike similar systems that are restricted to holes punched in the back of the system. Drain Main Basement System’s open back design allows water to enter the channel for the full length of joint where the footing and walls meet. Unlike other systems that restrict water intake to holes punched in the back channel.

Front toe channel feature keeps the seam where the old concrete meets new concrete bone dry. Drain Main Basement System’s front toe channel collects water directly under concrete seam keeping the seam between the old and new concrete bone dry after installation.

Drain Main designed to collect water from all the major sources of a wet basement. The 3 ridged spacers along the backside fin of the Drain Main Basement System catches water that may come down the wall from a crack or window well and channels it into the the system. Drain Main collects water seepage from the primary sources and quietly drains it away to the sump pump system leaving a bone dry basement.

The Drain Main Basement System was engineered and patented by Ken Cotten, WATERPROOF.COM founder, after decades of hands-on experience in the basement waterproofing installation business. Ken designed the Drain Main Basement System for waterproofing contractors seeking a subfloor system without the back-breaking work of drain tile.

Ken designed a basement system that would collect the water coming in from where the wall sat on the footer without losing or dumping water under the concrete slab. Ken engineered a waterproofing system that tapped into the main source of a wet basement and trapped it into the main channel by adding flexible PVC fins on the bottom of the channel, which reduced water from escaping under the system. This new system design also combined attributes of an above floor system that would collect water from the face of the basement walls and direct it into the Drain Main channel. The end result was the rugged footer drain known as the Drain Main Basement System, which requires far less concrete removal and no trenching under the floor.
