Expert Basement Wall Crack Repair in Aurora Naperville & All of Chicagoland

Get expert basement crack repair in Aurora, Naperville, and all of Chicagoland. We find the majority of basement cracks can be repaired using our polyurethane injections, which by far is the least invasive and most affordable way to keep your basement dry.

Our Process for Basement Crack Repair

  1. Identify the location of the cracks and assess their severity.
  2. Clean and prepare the crack for injection using specialized tools and equipment.
  3. Inject polyurethane or epoxy foam into the crack from the interior of the basement using specialized injection equipment.
  4. Allow the foam to cure and expand, filling the crack and permanently sealing it from the inside.
  5. In some cases, exterior waterproofing and sealing may also be used to prevent future water infiltration.

It’s worth noting that the specific steps taken may vary depending on the severity and location of the cracks, as well as the equipment and materials we use.  Our experienced techs will help you understand the specific steps they would take for your particular situation before a job is started.

Exterior Foundation Crack Repair for Your Home Basement in Aurora Naperville and Across The Greater Chicago Area

Exterior foundation crack repair is a process that involves several steps to ensure that the foundation is properly repaired and protected against water infiltration. Here are the general steps we follow when performing exterior foundation crack repair:

  1. Excavation: The first step in exterior foundation crack repair is excavation. This involves digging a trench around the perimeter of the foundation wall to expose the damaged area.
  2. Clean and prepare the area: Once the area is excavated, it needs to be cleaned and prepared. This may involve removing debris, dirt, and any loose or damaged materials from the surface of the foundation wall.
  3. Apply waterproofing membrane: After preparing the surface, a waterproofing membrane is applied to the foundation wall. The membrane is a thick, rubber-like material that is designed to seal the surface of the foundation wall and prevent water from penetrating it.
  4. Install drainage board: Once the membrane is applied, a drainage board is installed. This is a plastic sheet that has dimples on one side and a smooth surface on the other. The drainage board helps to direct water away from the foundation wall and towards the drainage system.
  5. Fill the crack: After the membrane and drainage board are installed, the crack is filled with a specialized sealant material. This material is designed to be flexible so that it can move with the foundation wall without cracking.
  6. Backfill and grade: Finally, the trench is backfilled with soil and graded away from the foundation wall. This helps to ensure that water flows away from the foundation and towards the drainage system.

Overall, exterior foundation crack repair can be an effective way to address foundation cracks and prevent water from entering your basement.
