What Gaithersburg's Ground Means for Your Basement

Clay-dominant ground conditions, which are prevalent throughout much of MD, build up hydrostatic pressure that cracks and infiltrates even solid concrete over time.

Gaithersburg and surrounding Gaithersburg, MD communities have a wide range of properties spanning decades of construction. Structures predating modern waterproofing codes regularly show the kind of slow-developing moisture problems that only become visible after significant damage has already occurred.
