Interior Drainage Systems: Keep Your Basement Dry from the Inside

Interior drainage is the most common and cost-effective approach to basement waterproofing. A channel is cut into the concrete floor along the perimeter walls, and a perforated drainage pipe is installed in a bed of washed gravel. Water that seeps through the walls or rises through the floor is captured by this drain and directed to a sump pit where a pump removes it from your home.

This approach works with the water rather than against it. Instead of trying to seal a porous concrete wall from the inside (which rarely works long-term), interior drainage manages the water efficiently and reliably.

Our systems are designed specifically for Colorado soil and water conditions. We use commercial-grade pipe, heavy-duty sump pumps with battery backup, and proper slope to ensure water flows to the pump consistently.
