Grate Drain vs. Floor Seepage - protecting against wet basements

One of the popular advantages of GrateDrain over other french drains is that it is specifically designed and installed to protect against floor seepage.

Floor seepage is when water pushes its way up through the floor of the basement. Cracks and separations can often make problems worse than they would be normally. However the problem that is causing the basement to become wet is the fact that water mass builds up under the floor of the basement.

As water builds, pressure is put on the underside of the concrete floor. As water seeks the path of least resistance, holes and separations are the first choice - but they're not always available - so water finds other ways in. The most common area that sees seepage is the perimeter around the basement; the gap between the wall and the basement floor.

Pressure can cause puddling in the middle of the floor, flooding, and wet spots around the perimeter of the basement.

How GrateDrain targets both, and Fixes them

GrateDrain, the french drain in question, has a bigger advantage of having holes on both sides of it. The holes are large and can accommodate large volumes of water. This is key to keep the volume of water under control under the basement floor. This is most importantly during a series of rain storms. The Grate Drain is installed so that the water drains into it inches before coming in contact with the bottom of the floor. This keeps the volume from building and building to the level of the footing and the floor.

This is important for a few reasons
1.) Moisture and water aren't touching the floor. This keeps puddling and floor crack seepage under control.
2.) It keeps water under the floor from jumping up on the footer and through the floor/wall gap.
3.) Volume is less shocking because it's under control most of the time - this is important for your drainage to be affective and also to increase the life of your sump pump.
