Fixing a Concrete Sidewalk Tripping Hazard with Polyurethane - Boston, MA

Joseph Coupal - Friday, January 29, 2016

We recently fixed a sidewalk tripping hazard where the responsible party got sued and was held responsible for fixing it. We were called to the City of Boston to one of the funeral parlors in town. There is a walkway to the front door. If you have ever noticed a concrete walkway, there are lines in it. Multiple sections had sunken, creating a tripping hazard. Someone tripped, so he asked us to see what we could do because it needed to be fixed right away. It has just been too cold to pour concrete, so he asked if there was any other way we could fix it.

So we drilled some small holes into the sunken slabs, put our ports in which were filled with our formula of polyurethane and injected it as a liquid. It expanded, and when it expanded it made the concrete rise so it was even so it was even with the other slabs of concrete. We did this in cold weather and it was less expensive than replacing the sidewalk. This can also work on a concrete driveway and roads.
