Concrete Island Causing a Serious Hazard, Whitby, ON Concrete Island Causing a Serious Hazard, Whitby, ON

A parking lot in Whitby, Ontario, had a concrete slabs that had sunken substantially on the inside the curb. This was causing many potential trip hazards for visitors to the Center. The Engineering Technician from the Town of Whitby wanted to fix this problem as soon as possible, before someone got hurt.    

The customer called Canadian Concrete Leveling to fix the island in the parking lot.  Our team injected PolyLevel foam into the sunken slabs. This lifted the concrete back to its original pour line and stabilized the concrete slab. The trip hazard is no longer existent and the technician is happy know they don't have to worry about it anymore.

A home in Whibty, Ontario had sinking concrete in their backyard. The patio around the pool had sunk a couple inches down and the step above the slab was becoming a trip hazard. This was also a concern because water was draining too close to the house. The customer was worried that water would intrude into the basement and further settling. 

The customer took precautions and called Clarke Basement Systems.  Billy McKeown and the Canadian Concrete Leveling crew came in and used PolyLevel Injections on the sinking patio by the house. The PolyLevel foam went deep beneath the concrete slab and filled in the voids that were allowing the concrete to sink. Now the customer has a leveled patio and no longer has to worry about water damage to the home.

PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete around your Whitby home is both an eyesore and a safety hazard. It is also likely to get worse with time, but we can fix it for you!

Our experts use PolyLevel, a superior polyurethane foam to provide reliable concrete lifting & leveling solutions. Small holes are drilled in the concrete and the expansion of the foam lifts & levels the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel. Call us today to learn more about our proven concrete lifting and leveling techniques.

  • Uneven Patios
  • Sinking Sidewalks

Concrete Island Causing a Serious Hazard, Whitby, ON

A parking lot in Whitby, Ontario, had a concrete island that had sunken substantially, inside the curb stones. This presented many potential trip hazards for visitors to the Centre, which the Engineering Technician from the Town of Whitby wanted us to alleviate.    

The customer called us regarding the area next to the electric car charging station in the Iroquois Center parking lot. Our team came and in injected PolyLevel foam. This lifted the concrete back to its original position and allowed the concrete to be stable for the future. The trip hazard is no longer there and the technician is happy know they don't have to worry about it anymore.

Hi there. I'm interested in a quote to raise my concrete pool deck. It has settled in one area. Thank you.
Grand Trunk St in Whitby
Part of the house used to be a deck and the foundation is above ground, as a result that part of the house is sinking. We need to put in support.
Kenneth Hobbs Ave in Whitby
There are a couple of spots in our small unfinished basement that have leaked in the past, and we have just noticed what appears to be a bit of mold in some insulation. We would like an estimate on having the mold safely removed, and having the walls sealed in some way to prevent future water intake. (We are planning to have the basement finished in the near future)
Gloria Cres. in Whitby
Hi there, I was wondering if you could send someone out to estimate a small lift (repair) of a crack that has formed in the stamped concrete deck around my pool where it has sunk in one area. We believe the underlying problem (cause) has been addressed so now I'm hoping to lift the section that has fallen slightly to close the crack and I like what I've read about foam-lifting vs. mud jacking. Also, do you also reseal concrete? The entire deck needs to be re-sealed as well so hoping to get that done at the same time and hopefully soon before the hot weather arrives. I'm located in Whitby, near Taunton and Baycliff.
DOVEDALE DR in Whitby
We have a small, very slow leak in the rear corner of our basement (a semi-detatched bungalow). The corner does happen to be where we have a downspout. It's been redirected since our initial problem, however with a very small leak, we want to get this fixed before re-finishing our basement. We're fairly certain we need to waterproof from the exterior. While that is done, we'll be looking to upgrade window wells and enlarge two - three windows. We'd love to get a quote on what the waterproofing would cost. - Taryn

Hi. We currently have two obvious leaks in our basement. It's a finished basement. My husband was able to locate the cracks in the foundation by cutting out some of the drywall. We believe it's just those two spots. We're looking to get a quote on what involved with repairing the cracks and ensuring there's no mold.
