Public Sidewalk Concrete Lift in Calgary

The Challenge - Heaving Sidewalk Panels

In numerous residential areas throughout the City of Calgary, the heaving of walk panels has become a major challenge for the City. City policy does not allow to cut back the roots causing the heave and replacing the concrete walk. Poly-Mor was asked to try and lift and align as best possible the heaved portions of walk.  

The Solution - Polymer Resin Injection

Working closely with the site engineers and drilling firm who drilled probe holes to the 5m depths. The predetermined drill pattern for the holes on the site was followed and 356 probes were undertaken on a staggered 1.5 m grid over a period of some 5 weeks. The longer than normal time to undertake the project was due to very tight timing schedules when work could be undertaken to allow for normal service of the Metrolinks system.

Should you have any void-filling, slab-lifting or soils stabilization challenge call Poly-Mor for a free estimate.
