Water intrusion is one of the most common challenges faced by homeowners in areas with fluctuating groundwater levels and heavy seasonal precipitation. At Complete Basement Systems, we use WaterGuard, an engineered, interior drainage solution designed specifically to intercept groundwater before it reaches the basement floor surface. The system integrates seamlessly with finishing options and provides a long-term, serviceable path for water removal.
What makes WaterGuard better than other waterproofing systems?
Conventional drainage systems, such as exterior drain tiles or above-slab trench systems, often struggle due to clogging, soil pressure, or insufficient flow paths. Many sit directly in the soil beneath the slab, leaving them vulnerable to silt and sediment buildup over time. WaterGuard is different by design.
How does it work?
WaterGuard sits on top of the foundation footing rather than beneath it. This allows water entering through leaking walls, wall-floor joints, or foundation cracks to be collected before it reaches the living space. Because the system avoids direct soil contact, it dramatically reduces the risk of clogging.
The drainage profile includes carefully placed perforations that allow groundwater to enter the channel from the cove joint and surrounding areas. This ensures the system captures water from multiple intrusion points, including:
Each WaterGuard installation includes dedicated service ports that allow technicians to inspect or flush the system in the future. This is a major advantage over exterior systems that are difficult or impossible to maintain without excavation.
Once collected, water is channeled to a sump pump. The pairing ensures that groundwater is efficiently removed from the home regardless of seasonal moisture or unexpected flooding events.
What is the installation process?
Break a narrow trench along the basement perimeter.
Remove concrete and expose the footing.
Place a layer of clean drainage stone to promote flow and reduce sediment contact.
Install the WaterGuard channel with proper grading toward the sump pit.
Fill around the system with additional drainage stone.
Seal the system with fresh concrete, leaving a clean finish flush with the existing slab.
The homeowner is left with a discreet, high-performance drainage system that requires little to no ongoing attention.
Does this guarantee a dry basement?
WaterGuard has been tested in thousands of homes across the country and is backed by a written, transferable warranty, ensuring the system is protected for the life of the home. Its engineering, combined with professional installation, makes it a reliable, permanent solution for controlling groundwater in basements.
