We size drain tile diameter and slope to your basement's actual perimeter footage and groundwater volume — undersized systems are a common reason DIY and budget installs fail within a few years.
We use dust containment systems during the concrete-cutting phase, keeping disruption to the rest of your home to a minimum.
You'll know the exact scope — partial wall or full perimeter — before you approve anything.
The gravel bed itself is sized to actual specification, not a shallow token layer, ensuring water reaches the pipe rather than pooling above it.
Every Interior Drainage System job starts with a real inspection — here's what that can include depending on what we find.
We saw-cut the slab perimeter, excavate to the footing along the affected walls, and install schedule 40 perforated drain tile in a gravel bed — capturing water at the source before it can rise above slab level.
The system routes to a properly sized sump pit with a dual-pump configuration for redundancy on higher-volume installations. That's the calculation most budget drain tile installs skip, and it's usually why they back up.

This keeps cost proportional to the actual scope of your water problem, tying the partial run into your existing or a new sump. We'd rather size it correctly the first time than have you calling about a system that can't keep up.
📞 Get a Free Quote →A vapor membrane is installed along the lower wall as part of the drain tile system, directing any wall-face seepage down into the drainage channel rather than onto your floor.
This addresses both floor-level and lower-wall moisture in a single integrated system rather than two separate fixes. Getting the sizing right up front is what keeps the system ahead of a heavy storm instead of behind it.
📞 Get a Free Quote →New or existing sump pits are evaluated for capacity against the drain tile's expected flow rate — an undersized pit paired with a new drainage system just moves the bottleneck downstream.
We upsize or rebuild the pit as needed so the whole system, not just the pipe, is rated for your actual water volume. We'd rather size it correctly the first time than have you calling about a system that can't keep up.

Freeze-prone runs receive a freeze-guard fitting so winter conditions don't compromise the system. Getting the sizing right up front is what keeps the system ahead of a heavy storm instead of behind it.

Inspections for Indian Head interior drainage jobs are typically scheduled within days, with installation following shortly after approval.
The technician measures the affected perimeter, checks your existing sump capacity, and quotes a fixed per-foot price for the scope needed.
Once approved, we cut, excavate, install the drain tile and sump tie-in, and finish with a written warranty on the completed system.
"Water showed up at the same spot along the back wall every time it rained hard. Full drain tile installation along that section tied into a new sump — hasn't shown up once since, through several heavy storms.Exactly the system that section needed."
"They actually calculated our drainage volume before sizing the sump pit, which the last company that quoted us didn't bother doing. System's kept up with everything so far, including one very heavy spring storm.System's kept up with everything so far."
"Only needed drainage along two walls, not the whole basement, and they quoted it that way instead of upselling a full-perimeter system we didn't need. Fair pricing and the fix has held completely.System's kept up with everything so far."
"Concrete cutting was noisy for about half a day but they used dust containment and cleaned up thoroughly. Drain tile and vapor membrane installed along the wall — floor's stayed dry since.Floor's stayed completely dry since."
