Below grade and split-slab waterproofing systems protect some of the most vulnerable areas of a commercial building. Foundations, plaza decks, parking structures, and occupied spaces below grade all require carefully selected waterproofing systems that prevent moisture intrusion and provide long-term protection.
Division 7 Waterproofing installs a wide range of below grade and split-slab waterproofing systems for commercial construction projects throughout Central Texas. We work with contractors, architects, and owners to select and install solutions that match the unique conditions of each project.
Waterproofing Below Grade Structures
Below grade construction presents unique challenges because walls and foundations remain in constant contact with surrounding soil and groundwater. Proper waterproofing protects structural concrete, reinforces the integrity of the building envelope, and helps prevent costly moisture problems long after construction is complete.
Our crews install systems designed to withstand demanding site conditions while coordinating closely with excavation, foundation, and structural work to keep projects moving efficiently.
Solutions for Complex Waterproofing Applications
Every project has different waterproofing requirements. We install a variety of membrane systems and specialty products that address everything from below grade foundations to split-slab assemblies, transitions, and leak remediation.
- Pre-applied waterproofing systems
- Post-applied waterproofing membranes
