Epoxy & Urethane Injections

Keeping Heavy Use Structures Safe, Stable, and Standing.

Thermal expansion and contraction causes movement and settlement within concrete structures. As a result, the concrete cracks, leaving room for water infiltration and damage. Epoxy injections can be used to mechanically bond the substrate at each of the cracks, providing stability and extended longevity to the structure. Our injection techniques will bring the performance of the concrete back up to the requirements of the original structural design.

Let’s protect your structure before small issues become big ones.

What are Urethane Injections?

Hydro-active urethane grout injections are performed when cracks within the concrete or pre-cast are not structurally sound and are allowing water infiltration. The urethane is injected within these cracks, where it expands to form a flexible gasket or multiple sealing points. When performed correctly by Masonry Restoration, Inc., urethane injection offers a cost effective option for repairing these cracks, eliminating the need for excavations to repair below-grade exterior walls.

Common Repair Triggers:

Active water leaks through cracks or joints in concrete
Damp or wet basement walls, tunnels, pits, or below-grade areas
Cracks that reopen after patching or surface repairs
Water infiltration where excavation isn’t practical or possible
Moisture showing up during heavy rain or seasonal groundwater rise

Why MRI?

Improper urethane injection can fail to seal the full crack depth, allowing leaks to return or worsen over time. Using the wrong material or technique may also trap moisture, cause hidden deterioration, or spark additional cracking. Masonry Restoration Inc. brings the experience, training, and precision needed to do it right the first time, ensuring the urethane expands correctly, penetrates fully, and forms a reliable, watertight seal that protects your structure for the long term.
