Concrete crack sealing is essential for maintaining the structural integrity and durability of concrete infrastructure. At QIS, we provide professional crack sealing services using advanced injection techniques to prevent water infiltration, protect structures, and extend service life. Our solutions are designed for residential, commercial, and industrial applications across Canada and the United States.

By sealing cracks early, we prevent further deterioration, structural damage, and costly repairs. Our injection methods ensure deep penetration and long-lasting protection in demanding environments.

At QIS, we use advanced crack sealing techniques and high-quality materials to deliver durable and reliable results. Our process involves injecting specialized polyurethane materials under controlled pressure to fully seal cracks and prevent water intrusion. We focus on precision, safety, and long-term performance in every project.

Hydrophobic Materials: Designed to repel water, these materials expand upon contact with moisture to effectively seal cracks and prevent water intrusion.

Hydrophilic Materials: These materials react with water to form a flexible seal, making them ideal for environments with continuous moisture exposure.

Inspection and Preparation: We start by thoroughly inspecting the crack to assess its size and extent. We then clean the crack to remove any debris, dust, or loose particles that could affect the sealant’s adhesion.

Routing (if necessary): To ensure a uniform and clean edge, we may route the crack. This step helps the sealant adhere better and ensures a more effective seal.

Injection: We inject the chosen sealant (hydrophobic or hydrophilic polyurethane) into the crack at high pressure. This ensures deep penetration and complete filling of the crack.

Curing: The sealant is allowed to cure, forming a solid, water-tight seal. Hydrophobic sealants expand to form a rigid foam, while hydrophilic sealants create a flexible gel.

Final Inspection: After the sealant has cured, we conduct a final inspection to ensure the crack is fully sealed and there are no leaks.

This injection-based method ensures deep penetration and long-lasting sealing performance.

Prevents Water Infiltration: Protects concrete structures from moisture damage and corrosion.

Extends Structural Life: Maintains integrity and prevents further cracking or deterioration.

Cost-Effective Solutions: Reduces the need for major repairs or full replacement.

Improved Durability: Strengthens concrete and enhances long-term performance.

Minimized Downtime: Quick application allows structures to return to service faster.

Concrete crack sealing is used in a wide range of applications, including foundations, tunnels, retaining walls, industrial floors, and underground structures. It is essential for maintaining infrastructure performance and preventing long-term damage.
