Interior Waterproofing Solutions

Interior waterproofing is exactly what it sounds like – a french drain and sump pump system placed on the inside of your home to channel water up and out before it has a chance to accumulate.

Sometimes called a french drain, these systems are installed below your basement’s concrete slab floor around the perimeter of the home. These drains rest against the inside of the foundation wall, collect any water that seeps in, and direct it to a sump pump pit where the water is then pumped up, out and away from your home. A major advantage to an interior system is that it doesn’t require massive excavation for installation. 

To install an interior system, small channels are chiseled out of the basement slab, the drains and sump pit are laid in, and new concrete is poured over the drain. While this does require you to provide access to the perimeter of your basement – which may mean replacing drywall or other finishing – most installations can be completed in one to two days.

Because quality french drain systems include cleaning ports, the risk of clogs from accumulating soil and debris is minimal. 

Thrasher Foundation Repair offers quality basement waterproofing products like innovative french drain systems and sump pumps for your home.
