What Dunellen's Ground Means for Your Basement

The ground conditions around Dunellen and Dunellen, NJ properties affects how quickly water intrusion happens and from which direction. Clay-dominant ground conditions, which are prevalent throughout much of NJ, retain moisture longer and create sustained lateral pressure against foundation walls. Understanding what you're dealing with underground is step one of any credible waterproofing diagnosis.

Properties built decades ago throughout Dunellen often lack adequate below-grade moisture protection. The SJ Waterproofing Pros crew serving Dunellen know the failure patterns specific to the housing stock in this part of NJ.
