Exterior Repair / Injection

Exterior Repair / Injection

When you need an exterior crack repair or injection, you probably have a lot of questions. Will this crack in the foundation compromise the strength and stability of your wall? Will it get bigger over time? Will the crack leak water into your home? What do you do to fix it?

Your smartest decision is to call an expert from Delta Waterproofing so that we can come and give you a thorough assessment of your foundation. An exterior crack repair is often recommended in situations for a crack in the foundation of the property.

A small excavation around the affected area is done to assess the severity of the damage, as well as check the condition of the weeping tile in case it needs to be addressed as well. We then clean up the surrounding area and remove the causes for the moisture penetration. After that, we inject a special epoxy or polyurethane product into the crack in that fills in the gap in the foundation and bonds to the walls, and we may add a series of carbon fiber staples to hold the structure in place.

We happily offer free inspections and estimates on repairs to cracked foundation walls. We’d love to hear from you today! Please see our Contact Us page so you can learn more about how Delta Waterproofing can help you with all your Foundation Crack Repair needs.
