Interior vs Exterior Waterproofing
Many homeowners frustratingly deal with wet basements. Water surrounding your home or seeping into your basement can cause structural damage if left unfixed. B-Level never uses a one-size-fits-all approach to basement waterproofing. We have several solutions to help and we offer both interior and exterior waterproofing systems. As a homeowner, you may not know which solution is best for you, so here we will discuss the basics of both systems.
Interior Waterproofing

Interior waterproofing is a popular choice if you have an unfinished basement or you are in the process of renovating. We start by removing approximately 12 inches of the concrete floor. Once the concrete is removed, a trench is created by digging out the old fill material (dirt or gravel) and weep holes are then drilled into the block wall. After the weep holes are drilled, perforated drain tile and a diverter are installed.
The perforated drain tile is sloped to redirect the water from the holes to the sump pump. The diverter is then placed on the wall to protect the holes and allow for a clear pathway that water can flow through. After the items are installed and the system is tested, the concrete that was removed during the installation process is replaced.
If your situation dictates that only a certain area of your basement needs an interior system, we will only treat that area. Interior systems are an excellent method to remove water from a wet basement.
Exterior Waterproofing
Exterior waterproofing allows us to stop the water at the source- outside. With the exterior waterproofing system, the water never actually enters the basement. Exterior waterproofing is a good option if you already have a finished basement and want a permanent solution. We start by excavating the perimeter of the home. The foundation wall is cleaned, cracks are patched, and a three-part protective membrane is then applied. A perforated exterior footer drain is installed at the base of the trench. It is sloped towards a sump pump area or a natural drain, where the water is then discharged out and away from your home. The trench is filled with gravel and fresh topsoil.

As with the interior system, if your situation dictates only a certain area of your home needs the exterior system, we can accommodate that area alone.
