Basement Structural Details

To understand how and why water leaks into your basement, it helps to have some basic knowledge about basement construction

Basic construction layout for a basement

What causes water to leak into a basement? It’s easy to blame a wet basement on mistakes made during a home’s construction process, but this is rarely the case. The truth is that a perfectly constructed basement foundation can have a water problem.

To understand why this is so, you just have to take a closer look at how a typical basement foundation is built.

As water pressure increases, so does the potential for leaks

The soil that’s backfilled against the walls of a basement foundation will always be looser and more permeable than the “virgin” soil wasn’t disturbed by the excavation process.

Higher permeability means that water will naturally collect against the foundation wall. An exterior foundation drain is supposed to provide an escape route for this groundwater, but these drains frequently fail.

Sometimes a section of the drain line is crushed during the backfilling process. Eventually even a properly installed exterior drain line will cease to function when it becomes clogged with roots and silt. With no escape route, hydrostatic pressure builds up against the foundation.

Water under pressure will naturally seek any crack, gap or hole, following the path of least resistance. In a basement, this leakage area is provided by the crack between the basement’s slab floor and the foundation wall. The crack exists because the concrete floor is poured in a separate process, after the basement walls are built. Builders deliberately create a gap between floor and wall to act as a control joint that can prevent cracks from forming in the center of the floor.

WaterGuard® drainage lines capture and control water before it reaches the basement floor

By installing a concealed drain line along the edges of your basement floor, your Basement Systems contractor can provide you with a waterproofing system that relieves hydrostatic pressure instead of forcing it to increase.

Patented WaterGuard® drain lines convey collected water to a sump pump that will automatically pump the water outside. The WaterGuard system is designed to capture water that seeps through basement walls as well as water that comes up along the floor.

Only the narrow top edge of the drainage system is visible in the finished installation. Because this interior drainage system is installed on top of the footing and inside basement walls, it can’t clog with silt or plant roots. It will always work effectively.

This foolproof basement waterproofing system can be installed in any basement. But you can only get it from a Basement Systems dealer, so make sure to call or email to find a Basement Systems contractor near you.
