Foundation Waterproofing in Southwest Washington & Northwest Oregon
Licensed & insured in WA & OR • Built for wet-season reality
Keep Water Out of Your Foundation
Water around a foundation rarely stays outside for long. When moisture builds up in the soil around your home, it looks for the easiest path through cracks, seams, and below-grade transitions.
At DC Waterproofing & Construction, we design foundation waterproofing systems that address the real source of the problem. Our approach begins with a thorough inspection so we can understand the water path and the site conditions around your structure. From there we install a system built to keep your foundation dry and protected for the long term.
Protecting your home from the ground up starts with the right waterproofing strategy.

DC Waterproofing & Construction is a family-owned company focused on long-lasting waterproofing solutions. We work with homeowners and builders who want the job handled carefully and installed the right way.
Our team uses proven materials and precision installation to protect foundations, basements, and structural concrete from water intrusion.
How Foundation Waterproofing Will Help You
Protect Your Structure
Water against a foundation can weaken materials over time. A proper waterproofing system protects concrete, framing, and interior spaces from moisture damage.
Prevent Ongoing Moisture Problems
Many water issues repeat because the original repair never addressed drainage. We design systems that redirect water away from the structure.
Protect Your Investment
Your foundation supports everything above it. Waterproofing protects the long-term stability of your home and reduces future repair costs.
What Goes Into a Proper Foundation Waterproofing System
Thorough Foundation Inspection
Every project begins with a careful inspection. We evaluate site grading, soil conditions, existing drainage, and the path water takes toward the structure.
Exterior Waterproofing Membrane
A durable waterproof membrane is applied to the foundation wall. This barrier prevents moisture from penetrating concrete surfaces below grade.
Drainage Strategy
Water must have somewhere to go. We install drainage components that redirect groundwater away from the foundation.
Protection Board and Wall Shielding
Drainage board or protective layers prevent soil pressure from damaging the waterproof membrane and help move water downward to the drainage system.
Crack and Joint Sealing
Transitions and foundation joints are common leak points. We detail these areas carefully to prevent water entry.
Backfill and Site Restoration
After installation, the foundation is properly backfilled and graded so surface water flows away from the home.
