Do I Need Waterproofing or Foundation Repair?
You may need waterproofing, Foundation Repair, or both. Waterproofing addresses water entry, drainage, sump pump demand, and moisture control. Foundation Repair addresses cracks, wall movement, settlement, masonry deterioration, and structural damage.
Why Do Basements Get Water Here?
Common causes include groundwater pressure, saturated soil, storm runoff, poor grading, downspout discharge, sump pump limitations, foundation cracks, older masonry, crawl space moisture, and water collecting near the foundation.

How We Approach Waterproofing & Foundation Problems in Raritan, NJ
1. Identify the Water Source
We look at whether water is entering from groundwater pressure, wall-floor joints, cracks, masonry walls, crawl spaces, basement entryways, sump pump limitations, storm runoff, concrete drainage issues, or grading problems around the home.
2. Review Foundation Type
Block, stone, brick, poured concrete, crawl space, and mixed foundations can require different waterproofing, drainage, masonry, concrete, and repair approaches.
3. Check Drainage, Concrete & Sump Pump Demand
Downspouts, grading, hardscapes, concrete slopes, discharge lines, soil saturation, and sump pump performance all help determine why water is reaching the foundation.
4. Build a Long-Term Repair Plan
Our goal is to reduce repeat water intrusion, protect the structure, improve moisture control, and avoid patch repairs that do not address the source.
