Why repair?


It’s much cheaper to repair concrete than replace it.

Sunken concrete is a significant problem that must be remediated to prevent further damage, liability or loss.  Replacing the concrete can be extremely expensive:  for example, removing and replacing a typical residential driveway can cost between $10000 and $15000.  Repairing that driveway by lifting the sunken concrete can cost much less – between $1500 and $3000.


Concrete replacement is hard on the environment.

In addition to the cost of removing and replacing concrete is the environmental impact of dumping broken concrete and rebar into landfills.  This can exceed 2-3 tons per residential driveway.


Old concrete correction is fraught with problems.

A much more cost effective and environmentally sound solution to replacement is to repair the concrete by lifting and re-leveling the slab.


Concrete lifting and leveling services have been around since the 1930s.  Old technology (called mudjacking or slabjacking) requires a large truck and crew to pump an extremely heavy mud slurry under the concrete pad.  Less than ideal, this method is time consuming, labour intensive, messy and requires large holes to be drilled into the concrete, ruining the aesthetic look of a clean slab. The weight of the concrete slurry can also further compound the problem as the mud adds weight to an already unstable subbase. 


Furthermore, the mud slurry can be eroded by water over time, requiring another repair job in the future.


A better way:  We use state-of-the-art technology to provide a more permanent, cost effective and aesthetic method for lifting and leveling concrete.


On the Level Concrete Correction uses rigorously tested and approved polyurethane rather than an unreliable mud slurry to permanently lift and support concrete slabs.


Environmentally safe technology.

The polyurethane foam is a revolutionary new foam produced and patented by HMI, a world leading manufacturer of concrete lifting equipment, training and material. HMI does not use blowing agents or toxic materials such as formaldehyde, benzene or toluene in its product.  The foam is made from recycled raw materials that were previously high quality foam—making it the “greenest” polyurethane foam on the market.


Polyurethane has been used in new home construction for decades and has been rigidly tested and approved by the Society for Testing and Materials (ASTM).   It has also been approved by the Environmental Protection Agency (EPA) to be as environmentally safe as the foam in your mattress or couch.  The EPA states that “cured polyurethane is sure unless burned or ground into a fine dust.”  The product will never degrade unless exposed to ultraviolet light, which is virtually impossible as the foam will be covered by a concrete pad.
