Stockade District brick, GE Realty Plot walkways, and newer paver patios out toward Niskayuna all sit on soil that heaves hard every February.
Older Schenectady installs were often laid on thin bases with plain masonry sand, so joints wash out fast and edges start to creep after a decade of freeze-thaw.
A pressure wash alone does not fix any of that. Once the joint sand is gone, the pavers lose their interlock and start moving — and every rainstorm carries more of the base away. Our restoration is a multi-day process: clean, blow the joints out to depth, install fresh polymeric sand, compact it in with a vibratory plate, then seal. That sequence is what makes the result last in Schenectady instead of failing by the next spring.
