What You Need to Know About Epoxy Injections

Epoxy Injections

Epoxy injections have been in use for many years in the construction industry. Many waterproofing contractors rely on them for waterproofing.


  1. It’s Strong

The tensile strength of concrete is between 300 and 700 psi. The tensile strength of epoxy once it has cured is about 7000 psi. Epoxy is actually much stronger than concrete. It is no wonder why many contractors use it for sealing cracks in concrete foundations.

The tensile strength of epoxy also make it the perfect choice for the repair of cracks in walls under great tension. Any material that cannot withstand the tension is likely to tear when pressure is applied to it. Epoxy seals remain in place even under great pressure.

  1. Immediate Visual Confirmation

Epoxy injections involve the use of a low pressure injection. This method of application allows the contractor to confirm that the crack has been filled completely before they declare the job complete. You therefore have immediate visual confirmation of the successful completion of the job.

  1. Low Failure Rate

If you’re looking for a solution that will ensure long term results, the epoxy injection is it. They have a proven low failure rate when applied by a properly trained technician. You won’t have to spend more money on subsequent repairs once you have had the injection applied to seal the cracks in your foundation.

  1. Can Be Used on Cracks of Different Sizes

This solution for waterproofing is highly effective even for the smallest cracks. Traditional methods are often difficult to use when dealing with small cracks. However, epoxy relies on the force of gravity when setting. The curing time allows for the epoxy to flow into small spaces. This ensures that even the smallest cracks are filled, preventing penetration of water.

You can also purchase epoxies of high viscosities when dealing with larger cracks. This ensures that the epoxy remains in place long enough to cure and provide an impenetrable seal.

Last Note

Epoxy injections are quite versatile. They also provide a fantastic method for sealing cracks in foundations. However, it is important to note that they shouldn’t be used as a primary waterproofing method. Epoxy is subject to shifting just like concrete is. These injections ought to be used in conjunction with other waterproofing solutions that deal with the underlying problem. This will provide the ultimate waterproofing solution for any foundation.
