PROTECTING STRUCTURES FROM CONSTANT MOISTURE EXPOSURE
Below-Grade Waterproofing
Below-grade environments expose buildings to hydrostatic pressure, groundwater, and soil moisture. Without effective waterproofing, moisture intrusion can lead to structural deterioration, interior damage, and long-term performance issues.
GKW Restoration delivers below-grade waterproofing systems designed to manage these conditions and protect foundations over the life of the structure.
System Selection & Installation
MATCHING SYSTEMS TO SITE CONDITIONS
Soil conditions, water table levels, foundation materials, and building use all influence waterproofing performance. GKW Restoration evaluates each project to select and install systems appropriate for the specific site and exposure conditions.
Typical Applications

Why GKW Restoration
Below-grade waterproofing failures are difficult and expensive to correct after installation. GKW Restoration’s experience and attention to detail help prevent issues before they occur.
Below-Grade Waterproofing FAQs
COMMON QUESTIONS ABOUT BELOW-GRADE PROTECTION
Failures are often caused by improper joint design, poor surface preparation, incompatible materials, UV exposure, or building movement exceeding the original design limits.
Yes. Existing structures can often be waterproofed through excavation or interior systems, depending on access and conditions.
Properly installed systems can last decades, but performance depends on materials, site conditions, and ongoing drainage management.
Yes. Effective waterproofing often works in combination with drainage systems to manage water pressure and reduce risk.
In most cases, no. This is why proper system selection and installation are critical from the start.
