Epoxy Injections

Epoxy injections repair a crack in a home’s basement wall by filling the crack with a combination of two components that, when mixed, work two ways: Sealing an existing crack and welding the structure. This method cures and places a seal over the damage while preventing more moisture from getting in.

Over time, the performance of the seal is actually more important than the welding itself, as the seal prevents premature deterioration of the foundation reinforcement. Compared to concrete, an epoxy injection provides more flexible strength and better compression – allowing for more of the natural expansion and contraction that homes can endure.

MDTI Epoxy Injection System Benefits

  • Moisture insensitive to cure on damp or wet surfaces
  • Easy 2:1 mix ratio
  • No shrinkage
  • Excellent adhesion to concrete, wood, and metals
  • Deep penetrating and tenacious bonding of cracks in structural concrete

The epoxy method of crack injection could be preferable for the homeowner because it is economical and relatively free of hassle. As with all of our products, epoxy offers a great way for a homeowner to protect their investment by preventing new water from entering and damaging their property. The epoxy itself is immensely flexible for any project, available in three levels for viscosity and applicable on most interior or exterior surfaces.

Epoxy injections are often the most cost-effective way to repair a crack in a foundation, provided the crack doesn’t exceed the recommended dimensions. If the damage is too extensive – if the crack is too large or the wall is too bowed – carbon fiber or wall anchors may be a more effective solution.

Installation of Epoxy Injections

Epoxy injection installation is fast, requires the work of just 2-3 team members, and offers minimal disruption – meaning the setup, installation, and cleanup will be quick and easy. Besides the epoxy system, the only tools necessary are a concrete drill, normal hand tools, and materials for cleaning holes and cracks.

With MDTI’s epoxy injection supplies, the process is even simpler: Just mix the two components at a 2:1 ratio to create the paste. Injection ports are inserted every 6-12” and the epoxy is injected into the crack. After all the ports are filled, the epoxy is left to cure for an average of seven days to completely harden.
