Interior Drainage Waterproofing Systems

Missouri basements are imperfect concrete structures built in soils that vary. Water in the soils leaking into basements is a problem that has troubled homeowners for over 100 years. This water will enter the basement through the walls, floors, and joints between them. Over the years, contractors and engineers have developed a wide variety of methods to keep basements dry. Some of these methods are more effective than others.

Among the best of these methods is to install a sub-floor drainage system along the perimeter of the floor. There are a few challenges to this method, however. One is to keep the drain from being clogged by mud over the years. Many homeowners go years without a water problem and then develop one because of existing sub-floor and sub-surface drains clogging with mud. Another is to set up the system to accept water from the walls without leaving a large unsightly gap at the edge of the floor that can collect dirt and debris from the floor, also clogging the drain.

The patented waterproofing system is designed to meet the challenges and keep your basement dry permanently.

This interior waterproofing system works on block and poured basement walls and leaves you with with a clean, dry basement for years to come.

Rubber Seals Trap Water In System! Rubber Seals Trap Water In System!

Basement Drain Main uses two co-extruded rubber seals along the bottom of the system to reduce dumping exterior wall water under the basement floor. Instead of dumping hydrostatic pressure under the basement floor, the Drain Main traps the hydrostatic pressure with the two rubber seals and uses the hydrostatic pressure to drive water to the sump pump.

Three rigid gussets create fluid chambers. As water levels rise into these chambers, a water level effect takes over and drives high water towards low water (sump pump) as water always is self-leveling. The three rigid gussets filter debris from floating up into this natural drive mechanism.

Basement floor cracks seep water primarily because of hydrostatic pressure that feeds in from the end cuts of floor cracks that meet exterior walls. In many cases, a simple installation of a sump pump is all it takes to eliminate minor problems.

The Basement Drain Main's leak guard is a secondary channel to collect back flow from under the footings. The leak guard channel also offers protection against water seepage up through the crack formed by pouring new concrete up against existing concrete.

Because I live in St. Charles and my property was in Mexico, I thought this would be a problem. Everyone at Advanced was easy to work with and that made it easier. Thanks for doing a good job!
