Why should I repair my foundation?

There are numerous reasons. Amongst the most common reasons are: it promotes a healthier living environment, avoids further damage to your belongings, and increases property value and peace of mind.

What are the benefits of using epoxy over polyurethane?

  • Epoxy injections structurally repair the concrete
  • Epoxies are much stronger compared to urethane
  • Epoxies effectively stop water from entering the building

What is epoxy?

Injecting epoxies from the inside of the building repairs cracks on the basement wall. Epoxies are in a liquid form and made of two components that are mixed even as it is injected into the crack. When the components mix, they cure and form a strong and durable material that reinforces the wall. Compared to concrete, epoxies are highly tensile and strong and have high compression. After injecting the crack with our high-quality epoxy, you can be sure you will not face the problem of leakage.


The process of injecting epoxy into the cracks is quite simple. A special paste attaches plastic injection ports every six to twelve inches.


The special surface paste is then applied to the other parts of the crack after attaching the ports. This ensures that during the hardening process, epoxy is retained in the crack.


The third step is the actual injection of epoxy into the crack. Starting from the lowest port, epoxy is injected throughout the crack. The epoxy cartridge is inserted into the port after attaching a mixer to it. Upon injecting, the epoxy flows right up to the outer surface of the crack. All ports are injected and the epoxy is left to cure. It takes an average of seven days for epoxies to cure and completely harden..

What is this white powder on my foundation?

This is mineral deposit left behind when moisture dries and crystallizes. It is referred to as efflorescence. This can be removed with a mixture of warm water and vinegar.

What happens if the problem recurs after you do the work?

Though only a small percentage of our work requires service, we are as anxious to solve your problem as you are. Much of the reason for our growth over the past 30+ years is because we truly stand behind our work.

My basement is finished. How do I fix the problem?

Because we are a full-service waterproofing contractor, our basement advisors have a number of solutions to choose from. In many cases, all the work can be done from the exterior. If that is not practical or possible, we can solve the problem from the interior with little impact on the interior finishes. This may include such simple things as removing a section of the drywall, removing baseboards or pulling back carpet.
