Chemical Injection in Mechanical Room

Chemical Injection in Mechanical Room

Location: Toronto, ON
Sector: Residencial
Category: Chemical Grouting

Description

A building restoration contractor experienced water leakage into the mechanical room from 2” diameter holes which contained glycol lines running through them, to melt snow on a vehicle ramp.

Working within the mechanical room, 5/16” break lines were placed at a depth of 8” into the holes. These holes were then sealed with hydraulic cement, and when cured water was then introduced through the brake lines into the holes. Polyurethane resin was then injected into the holes, filling the holes and forming a semi-rigid foam barrier, preventing further water leakage.

Chemical grout injection using Universal Resin, Universal Accelerator, 5/16” brake lines, and two grout injection pumps were used to fill the holes in the wall. The technique eliminated further water leakage into the mechanical room.

Soil stabilization in high-rise development construction

Soil Stabilization for High-rise Development Construction

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

Description

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.

Leak Sealing in an Underground Chamber

Location: Toronto, ON
Sector: Utilities
Category: Chemical Grouting, Crack Injection

Description

A utility contractor needed a permanent solution to fix an underground chamber that was prone to repeated flooding through leaking pipe penetrations.

Multiurethanes’ technicians used chemical grout to fill the annular space around the pipe penetration and fix the source of the water inflows.

Fill stabilization around a manhole

Location: Toronto, ON
Sector: Utilities
Category: Chemical Grouting, Crack Injection

Description

Loose fill surrounding a manhole structure required stabilization. Multiurethanes technicians injected Universal Resin through vertical injection pipes to stabilize the fill prior to cutting through the structure wall.

Leak sealing and crack injection around industrial pipe penetrations

Crack Injection around Industrial Pipe Penetrations

Location: Kapuskasing, ON
Sector: Infrastructure
Category: Crack Injection

Description

A large contractor was looking for a uniquely qualified partner to complete concrete crack injection work at Little Long Generating Station, a remote Northern construction project.

This job involved precision drilling work for crack injection to avoid the unknown conduits and pipes buried within the structure. Multiurethanes experienced technicians completed the project professionally and on time.
