  • Exterior waterproofing is the best way to repair a basement leak and keep a basement dry.​

  • Exterior waterproofing applications address all water seepage and foundation crack issues, which typically come from the outside of the home.​​

  • Exterior waterproofing protects the foundation of your home.




  • Interior Waterproofing is a Water Management System.​

  • Interior Waterproofing installation is a cost-effective alternative to Exterior Waterproofing.

  • Interior Waterproofing repairs basement leaks and keeps basements dry BUT interior waterproofing does not protect your home's foundation from concrete cracks or shifting.

  • The interior waterproofing system is used if exterior waterproofing is unfeasible or deemed unsafe.


Exterior Waterproofing Process

4. Apply Protective Layer Three

The third protective layer is a polyethylene-dimpled drainage mat. This heavy gauge mat is known as waterproofing membrane. Waterproofing membrane is ideal for protecting the liquid membrane (Protective layer 2) that was installed on the foundation wall.

5. Install Weeping Tile

The new weeping tile system will keep the exterior water level below the floor of your basement. A clean weeping tile system will collect sub-grade pooling water, keeping your basement foundation walls both pressure and leak-free.

6. Backfill and Clean Up

Once your waterproofing work is complete the Nusite Contractors team will backfill the excavated area with 3/4 clear gravel and the excavated soil. We will also restore your homes' landscaping to its original condition. After that, the site is cleaned and your foundation will be leak-free.

1. Excavation

The first step of the exterior waterproofing process is the removal of the dirt and clay surrounding the cracked foundation walls.​​

2. Foundation Repair

Once the cracked wall is fully exposed, the Nusite team will complete a thorough check of your foundation wall and footings. At this point, all foundation cracks are strengthened with hydraulic cement (Protective Layer One).

3. Apply Protective Layer Two

The third step of the exterior waterproofing process is the application of an elastomeric membrane. The pliable polymer-modified asphalt membrane is applied to the foundation wall, which heals itself if new cracks develop.

Interior Waterproofing Process

3. Install the Weeping Tile

Weeping tile is now installed into the channel. The weeping holes are then drilled into the bottom of your concrete blocks and your weeping tile is secured.

4. Apply the Drainage Mat

The polyethylene-dimpled drainage mats are then installed. This membrane uses dimples to create an air gap that directs moisture to your drain. Any water that pools under your basement floor will travel through the weeping tile system to the sump pump liner. The sump pump is what pushes water back outside of the home.

1. Access the Wall

The first step of the interior waterproofing process is to gain access to the bare basement foundation wall. If you have a finished basement this can be done by removing stud walls (or the lower part of them).

2. Open the Floor Slab

After the foundation wall is exposed we dig a channel for the weeping tile to lay. To create a weeping tile channel, our team will remove approximately 18 inches of the floor slab surrounding your foundation walls.
