Waterproofing & Sealing

Safeguard Your San Jose Property with Expert Waterproofing & Sealing Solutions
Stop Leaks, Mold & Structural Damage – Lifetime Warranties & Free Inspections

Water intrusion isn’t just a nuisance—it’s a silent destroyer. From cracked foundations to soggy crawl spaces, unchecked moisture can rot wood, breed toxic mold, and cost thousands in repairs. RCabral Contractor provides comprehensive waterproofing and sealing services across San Jose, using industrial-grade membranes, French drain systems, and climate-smart techniques to shield your home from Silicon Valley’s rainy winters, groundwater seepage, and humidity. Whether you need basement waterproofing, deck sealing, or crack injection, we deliver permanent solutions that protect your property’s value and health.

Why San Jose Homeowners Trust Us for Waterproofing:
✅ Proactive Defense: Install interior/exterior drainage systems, sump pumps, and hydrostatic pressure relief to redirect water away from your foundation.
✅ Mold Prevention: EPA-registered antimicrobial treatments to stop spore growth in crawl spaces and garage floors.
✅ Local Climate Mastery: Use UV-resistant sealants for sun-exposed surfaces and flexible epoxy for seismic shifts common in Bay Area soils.
✅ Code Compliance: Meet Santa Clara County regulations for grading, vapor barriers, and stormwater management.

Our 6-Step Waterproofing Process

Free Moisture Audit: Thermal imaging and moisture meters to pinpoint leaks in basements, roofs, or balconies.
Customized Plan: Recommend solutions like exterior foundation coating, interior dimple boards, or downspout extensions.
Surface Prep: Clean, repair cracks, and apply etching agents for maximum adhesion.
Advanced Application: Roll/spray rubberized asphalt, polyurethane sealants, or crystalline waterproofing for concrete.
Drainage Integration: Install perimeter drains, catch basins, or grading adjustments to divert water away.
Final Validation: Simulate heavy rain with flood testing and provide a 25-year transferable warranty.

Don’t Wait for Disaster

Temporary fixes like store-bought sealants fail under pressure, leading to recurring floods and black mold outbreaks.
We guarantee:
✔️ 10-Year Leak-Free Warranty
✔️ Financing Options for Large-Scale Projects
✔️ 24/7 Emergency Response for Burst Pipes or Storm Damage
