Epoxy injection is a waterproof, structural, and permanent fix for leaking concrete structures. The resin used during the repair bonds the structure back to the monolithic state of its original design. Unlike other repair types, epoxy does not trap water within the substrate or shrink over time, making it our preferred material choice.

Epoxy injection crack repair is successful for both dry and wet cracks. With proper equipment, epoxy penetrates the entire width and depth under pressure and achieves a mechanical bond. Product knowledge and training are key to selecting the best preparation method and best resin for the project. This is especially critical when dealing with leaking concrete.

Has your home or business suffered from interior water damage? Are vehicles in your parking garage getting water spots or staining from efflorescence? Whatever the cause, water damage is no fun. Epoxy injection is both an active repair as well as preventative maintenance. By eliminating leaks, you are preventing mold growth, corrosion induced delamination, and wood rot.

Miller & Co has leak repair experts ready to tackle your concrete leaks. We offer fast, reliable injection services with a “no job too big, no job too small” attitude.

Urethanes can be found in many forms, single component, plural component, hydrophobic, hydrophilic flexible, rigid etc. Urethanes react with water or accelerator as part of the curing process, often incorporating air into the cure to create an expanding foam. The product may break down in the presence of incorrect moisture compatibility and/or due to shrinkage. Urethane is a non-structural method of stopping water ingress and will prevent any future structural repairs in repair locations.

Urethane is one of the most common injection materials installed into cracks, and is widely available for DIY clients as well as contractors. Many contractors recommend urethane over epoxy simply because it is the only product they know how to install, or have in stock.

Curtain Wall

Curtain wall injection uses a urethane or acrylate injection resin to provide blind side waterproofing and/or void filling to prevent water ingress. Curtain walls may be required in conjunction with other repairs such as fixing honeycombing in concrete or moisture saturation in porous structures. Repairs are done by drilling holes in a grid pattern, setting ports, and injecting the repair material.

Efflorescence, flaking concrete, loose or bubbled paint, damp spots, mold and excess moisture can happen to a below grade concrete or masonry walls. This happens when poor drainage causes water to sit against a structure.

Usually water will leak through a crack or hole, however with enough time and water moisture can transfer through the porous wall with no other defects present. For residential situations usually excavating and repairing the drainage and membrane is possible, however when the depth or construction location do not allow for standard repair procedures, curtain wall injection can be the answer. For example, a leaking elevator pit in a tower will be the deepest accessible spot in the entire structure, with no chance of simply digging to expose the wall. When situations like this come up, Miller & Co can advise on what the best solution is.

Frequently Asked Questions


Epoxy injection is the recommended repair type for structural cracks, and cracks in a rigid structure.  If a structure’s design includes expansion joints, they will always be maintained and never injected with epoxy. In most cases; a non-structural, flexible material provides no added benefit over epoxy.

The first step is sealing the water from coming out of the concrete while also placing ports to pump material into. Once the crack is sealed, it can be injected with resin to chase the water out following it to the source of ingress. This eliminates water from leaking out of the wall and prevents water from being trapped inside the concrete. Hiring a knowledgeable contractor with the right equipment and materials on hand will ensure a permanent fix is achieved.
