Epoxy

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.

Urethane

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

FAQ

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.

The most common cracks occur in the center of the all and are due to shrinkage of the concrete. Other cracks may occur due to settling or vibrations through neighboring construction.

Cracked concrete is not usually going to lead to major changes in the strength of the structure, due to internal rebar reinforcing. The biggest concern with cracks is water infiltration that can happen at anytime, due to changes in drainage or soil moisture.

 

The most common repairs are with local materials; caulking, hydraulic cement, crystalline waterproofing and urethane. These are not to be mistaken with the BEST localized repair method, epoxy injection.

Calling a roofing company or concrete installation company will likely get you a repair bill in the thousands of dollars. A DIY repair might hit a hundred dollars at the store. With professionals like Miller & Co, for less than a thousand dollars you get a lifetime warranty for water ingress and re-cracking. Epoxy injection is both cost effective, and permanent so why not chose to pay once and not over and over again.

Epoxy injection is stronger than concrete. With our lifetime warranty, potential home buyers will not have to worry about cracks once they purchase the home.

The most economical epoxy injection leaves surface seals intact, but once resin has cured the seals can be removed. For minimal extra cost the work area can be ground flush for a reduced visual impact. To eliminate all evidence, painting or parging can be performed.

We stand behind our materials and processes. With repairs holding up to extreme industrial applications and commercial structures, residential repairs are done a walk in the park for us. Hiring Miller & Co for your residential crack repair will get you a LIFETIME WARRANTY.

Cracks don’t get better by themselves. Moisture levels may change, and leaking may stop but that doesn’t solve the potential for future leaking. Although monitoring cracks is possible with scratch-tracking cards or other crack monitors, we recommend repairing cracks ASAP. Structurally repair your concrete cracks, instead of forming long term relationships with them.

The question isn’t if, but when. perimeter drains can become clogged by tree roots. Sump pumps may fail in a power outage. waterproof membranes are designed to stretch to a certain % but inevitably fail when a crack gets to a certain point. Instead allowing the potential for water ingress to linger, address cracks once they are found.

Exterior waterproofing requires exposing all below grade structure. With epoxy injection, work can be done from either side of the wall depending on what will be more cost effective. There is no change in the quality of workmanship based on what side of the wall injection work is performed on. This is because with the proper epoxy resin and equipment the crack will be filled fully with epoxy.

Epoxy injection is a method of filling and sealing cracks in concrete. It involves injecting epoxy resin at pressure into the cracks, which cures to form a strong bond with the concrete in wet or dry conditions. In wet conditions, the appropriate viscosity material is critical to displace water out of the crack. Proper preparation and equipment will allow adequate injection pressure. Resin under pressure allows the epoxy to mechanically bond with the pores and capillaries of the concrete.
