How Does Epoxy Crack Injection Work?

The process begins with a thorough inspection and surface preparation. The damaged concrete surface is cleaned of debris, dust, and any contaminants that might interfere with the epoxy bonding to the surface of the concrete. After prepping the concrete, Alpine Companies will then install a series of Simpson E-Z-Click Flush Mount Ports along the length of the crack. These ports act as access points for the epoxy injection and are precisely spaced to maximize coverage and penetration. This is where the experience comes in, if the ports are not installed on the concrete cracks, the repair will fail. Alpine Companies fail proof techniques are guaranteed to prevent this from happening and that can only come from the knowledge and experience that over 60 years can achieve. 

Alpine Companies then selects the best Simpson epoxy resin for the application and it is then mixed and pressure-injected directly into the ports. For most residential or commercial applications, Simpson LV (Low Viscosity) Epoxy is used for standard-width cracks, while the SLV (Super Low Viscosity) Epoxy is ideal for hairline or very narrow cracks. The low viscosity of these epoxies allows them to flow deeply and completely into the smallest fissures within the concrete, ensuring a thorough and lasting repair.
Once injected, the epoxy chemically cures and hardens, bonding the cracked sections together at a molecular level. The repair is not just cosmetic—it structurally integrates with the original concrete, often leaving the repaired area stronger than the surrounding material. 

Why Is Epoxy or Polyurethane Injection Necessary?

Concrete is prone to cracking and movement due to changing temperatures, hydrostatic pressure, poor drainage issues around the perimeter of the homes foundation, improperly installed or missing downspouts as well as normal environmental moisture. Here in Denver Colorado we experience drastic seasonal swings. During hot summers, concrete expands and contracts, allowing hidden moisture and spring flooding rains to seep deeper into cracks flooding your basement or crawlspace. When winter arrives, the adjacent soil freezes and puts added pressure on basement walls and slabs, causing cracks to widen and further compromising the structural integrity of the foundation. This cycle can lead to chronic water intrusion, flooding, and even structural failure if left unaddressed. In Colorado we also have high water tables that cause hydrostatic pressure buildup against the adjacent concrete slabs and foundation which then cause the concrete to crack and the water to flood into the home. 

Epoxy injection crack repair creates a permanent, watertight seal that eliminates water intrusion and restores the structural integrity of your foundation, basement walls, crawlspace walls, garage floors, or commercial applications.
