Job Stories From Charlestown, NH
Saving a Sinking Walkway in Charlestown, New Hampshire, by Matt Clark's Northern Basement Systems

In Charlestown, New Hampshire, a family was looking into replacing the walkway at their home.  An unfortunate incident occurred when an elderly family member was visiting fell twice on two different, very uneven sections of the concrete walkway.  The family had received a local contractor's suggestion, with whom they used for many projects around their house. 

He suggested getting an estimate from Matt Clark's Northern Basement Systems.  He told the family he had seen Northern Basement Systems use this technology on a driveway for one of his other clients and loved the results.  

The homeowner hired Matt Clark's Northern Basement Systems, successfully raising the walkway back to a safe, level position using Polylevel Injections.

Project Location: Charlestown, NH
I have a rather large deck supported by concrete posts in sonotubes. I only peeled the cardboard off section of sonotube that remained above ground. Sonotubes are 4' Under ground however we are realizing that it is very sandy soil. In any case the concrete posts have sunk a bit causing the deck to also sink. Hoping the polylevel can raise the concrete posts back to where they originally were. The most severe drop located in 1 post was 2-1/2" or so. For now we jacked up the deck and cut a whole new 6x6 to make up for the difference. We intend on concreting around the top of every post to prevent sinking in the future.
