Sinking Walkway Threatens Customers at Plaza in Ajax, Ontario

A plaza manager has many behind-the-scenes tasks along with managing tenant and customer needs. They ensure everything is safe and in proper working order.

A building manager in Ajax, Ontario, received a few complaints from tenants about sinking concrete in front of the parking lot. The area became a tripping hazard and a troublesome spot for pooling water.

Project Manager Joe McColl inspected the concrete at the strip mall. Joe explained to the customer that voids under the slab make the concrete sink. The customer did not want to deal with the expensive hassle of new concrete and closing the stores for a few days.

To his delight, the manager learned he could leave the stores open during the installation and use the concrete later the same day. Joe explained how our PolyLevel® System repairs the concrete using high-density polyurethane injections. This solution is non-invasive – a 300-foot hose pumps polyurethane to voids under the concrete.

Foreman Bill McKeown started the repair by drilling dime-sized holes in the concrete surface. As he injects the polyurethane beneath the slabs, the concrete lifts back to grade level while compressing fill soils below. All spaces and cavities are filled fixing the concrete issues permanently.

The building manager truly appreciates how efficient the installation was executed. He didn’t need to close down the building, and his tenants are happy their customers can use a safe walkway.
