Restore the integrity of concrete structures with Building Chemical Supplies
Our expert repair solutions restore structural integrity, prevent water infiltration and corrosion, and extend the lifespan of concrete structures—all while offering a cost-effective alternative to full replacement.
Over two decades of concrete repair and crack injection excellence
Building Chemical Supplies has over 20 years of experience in concrete repair and crack injection, combining the best products and services with unmatched expertise and unblemished results.
Our concrete spalling repair solutions
Unlike concrete cracks, which are often caused by stress or pressure and are addressed through sealing or filling, spalling primarily results from the deterioration of the concrete's core caused by moisture infiltration and the corrosion of the steel reinforcement. Spalling focuses on repairing the loss of surface material and restoring the integrity of the underlying structure.
With a wide range of standard and custom solutions available, our expert team applies advanced injection systems, sealants and waterproof barriers such as:
Epoxy injection
Epoxy injection is ideal for bonding structural cracks, achieving a permanent, high-strength solution that restores the integrity and stability of compromised structures. This approach ensures long-lasting results that prevent further damage, saving you from costly repairs down the line.
Polyurethane (PU) injection
Polyurethane injection is designed to seal cracks and joints where water ingress is an issue. Its flexibility allows it to expand and contract with the movement of the structure, offering a reliable and adaptable solution that prevents leaks and moisture-related damage.
Surface sealing and stitching
Surface sealing and stitching are used to reinforce areas that have been weakened or compromised, providing added strength and stability. This approach not only strengthens the affected areas but also helps maintain the overall integrity of the structure, ensuring it remains safe and functional.
Crack routing and sealing
Crack routing and sealing help stop existing cracks from spreading or worsening. By creating a clean path for the sealant, we achieve a durable bond that prevents water infiltration and further deterioration, ultimately extending the structure's lifespan.
Causes of concrete cracks
If you're dealing with concrete cracks, our expert team can assess the issue and offer precise crack injection solutions to restore your structure’s integrity and prevent further damage. Contact us today to find out how we can help.
Structural stress and load
Heavy loads or excessive pressure on concrete surfaces can lead to cracks. This often happens in areas where the concrete is subjected to more weight than it was designed to withstand, causing stress and resulting in visible fissures.
Shrinkage and temperature variations
Concrete naturally shrinks as it cures; temperature changes can cause it to expand and contract. Over time, these cycles of expansion and contraction can lead to cracking, particularly in large or poorly controlled areas.
Moisture infiltration and chemical exposure
Water penetration is a leading cause of concrete damage, as moisture can weaken the material and lead to cracking. Exposure to harsh chemicals, salts, and other corrosive substances can accelerate concrete deterioration, further contributing to crack formation.
Foundation movement and settlement
Shifting foundations due to soil movement, settling, or erosion can cause the concrete above to crack. As the foundation settles or shifts unevenly, pressure is placed on the concrete, often resulting in cracking, especially in walls and floors.
