Foundation Waterproofing in Florida: What 75 Years of Coastal Work Taught Us

Most foundation waterproofing in Florida fails within 10 years because the contractor used the wrong system for the local soil and water table conditions. A coating that works in Georgia does not survive South Florida's hydrostatic pressure, and a drainage mat designed for clay soils is useless in Palm Beach's sandy, high-water-table environment. Here is what 75 years of foundation work in coastal Florida taught us about what actually keeps water out.

Why Waterproofing is Critical

• • Prevents moisture buildup and hydrostatic pressure that drives cracks and leaks.
• • Protects structural integrity in coastal, humid environments.
• • Saves thousands vs. future foundation repairs.

Materials & Tools

• • Sealant (e.g., Deco 20 Seal), crack fillers, mortar, primer (if required)
• • Airless sprayer; brushes/rollers for detail areas
• • Stiff-bristle brush, drop cloths, gloves, goggles, mask

Step-by-Step Waterproofing

1. Inspect & prep: expose wall, clean, repair cracks, repoint mortar.
2. Surface repair: ensure a smooth, sound substrate.
3. Apply sealant: two uniform coats; focus on base/footing areas.
4. Add drainage: French drain, regrade soil to slope away.
5. Landscaping: rain gardens or permeable pavers to reduce runoff near the foundation.
