Crack injection in underground parking garage

Chemical Injection in Underground Parking Garage

Location: Burlington, ON
Sector: Infrastructure
Category: Chemical Grouting


A building and garage restoration contractor observed extensive cracks in the concrete and water infiltration through the foundation walls.

Working within the underground parking garage, 3/8 inch diameter holes, every 8 inches at a depth of 10 inches were drilled. Alternating holes were drilled on each side of the crack, at a 60 degree angle to intersect the crack at the mid-point of the foundation wall. Plastic packers were then installed into the drilled holes, and flushed with water/acid solution to rid debris from the holes and the crack itself.

Chemical grout was then injected into the drilled holes filling the fine cracks and forming a flexible foam barrier, sealing the crack, preventing further water discharge.

Chemical grout injection using Multiurethanes Flexible Resin and Flexible Accelerator, Multiurethanes Crack Flushing Agent, 3/8″ plastic packers and two chemical grout pumps were used to seal the cracks in the foundation wall.

The application eliminated the continued water seepage into the garage, allowing for the parking garage to be returned to service.

Soil stabilization in high-rise development construction

Soil Stabilization for High-rise Development Construction

Location: Toronto, ON
Sector: Residencial
Category: Soil Stabilization


While working on site at a Toronto Lakeshore high-rise development adjacent to Lake Ontario, Multiurethanes encountered a challenging situation performing water abatement and soil stabilization for the required high-rise foundation construction. With frigid January temperatures, the soil on one side of the wall became too unstable to work around. The site superintendents decided to halt all construction work while Multiurethanes stabilized the soil and stopped the flow of water.

Our grouting specialists faced with the challenge of securing the worksite to achieve these goals. Our team developed an innovative and unique solution; consisting of attaching a metal plate between perpendicular supports to strengthen the cracked wall, drilling grout equipment access holes in the metal plate, and performing cement grouting injections.

This solution proved to be very successful and our client was extremely impressed with our team’s innovation and quick thinking to de-escalate an unsafe work environment, as well as the completion of our assigned tasks. They have since asked us to perform this same solution technique to other challenging projects.
