Dry Basements Start With Interior Waterproofing in Detroit
Groundwater seeping into your basement slab doesn't always mean you need to excavate the outside. Detroit Concrete installs interior drainage systems that intercept water at the perimeter, route it to a sump pit, and pump it away before it reaches your finished space. This approach works when exterior access is limited or when the cost of outside work is prohibitive. Call us for a free site visit and written estimate.
Not every wet basement calls for exterior excavation. If your lot is tight, your landscape is established, or you have a deck or garage blocking access to the foundation wall, digging outside becomes expensive or impossible. Interior waterproofing offers a proven alternative that keeps the slab dry and lets you finish the basement.
The system works by accepting that water will reach the wall, then stopping it at the slab line. We cut a trench along the perimeter, lay drainage tile on stone, slope it to a sump pit, and install a pump that moves water to daylight. The wall seals at the base so moisture can dry inward instead of bleeding across the concrete floor.
The result is a dry basement ready for renovation work, finished flooring, and storage. The pump is the only moving part, and it runs only when water arrives. Pair this with a basement crack repair if you have active leaks in the wall itself, and you have a complete solution.

Installation sequence
How We Install Interior Drainage in Your Basement
Assess water entry and sump location
We identify where water reaches the slab, measure the existing floor depth, and locate the best spot for the sump pit and discharge line before any cutting begins.
Cut and excavate the perimeter
The basement floor is cut along the wall line, a trench is dug to the correct depth, and any failed or clogged drainage is removed so the new tile sits on clean stone.
Lay tile, set pit, install pump
Drainage tile is placed in the trench on a stone bed, sloped toward a new sump pit at the low point. The pump and discharge line are installed and tested with water to confirm flow.
Backfill, pour, and seal
Stone backfill is compacted over the tile, a new concrete slab is poured to lock the system into the floor, and the wall base is sealed so the wall dries inward without wetting the new slab.
Interior vs. exterior
Interior Waterproofing Fits Specific Situations
Interior waterproofing is not a replacement for fixing structural foundation problems. If your wall is cracking due to settlement or if there is a known exterior cause you can reasonably reach, exterior foundation waterproofing remains the best choice.
Interior systems excel in established homes where the outside is finished and a recurring leak is the problem. They also work well when your goal is to get the slab dry enough to complete a basement floor or finish work. The pump is the only component that needs maintenance, and the basement stays dry through spring melt and heavy rain.
Drainage tile, sump pits, pumps and when interior is the right choice for a wet basement.
For its job, yes. The two systems do different work. Exterior keeps water from ever reaching the wall; interior accepts that water reaches the wall, intercepts it at the slab perimeter and pumps it out. When excavating outside is impractical, the interior system is the right one.
An interior system needs a sump pit and a pump to move collected water out. A battery backup pump is strongly recommended in Detroit, where spring runoff and power outages can overlap. We size the pump and pit to the inflow we measure.
The perimeter has to be opened up, which means baseboards, lower drywall and any finished flooring against the wall come off in the work zone. We coordinate that carefully so the rest of the basement is undisturbed.
It will intercept the water at the slab so the floor stays dry, but a leaking wall crack itself is a separate fix; pair this with crack repair or, if the crack is structural, foundation crack repair from the engineered side.
A typical residential interior system takes about a week from cut to closed slab, depending on the perimeter length and how much of the basement has to be uncovered to reach the work. The full schedule is in the quote.

What Detroit Homeowners Say About Interior Waterproofing
We could not dig up the front of the house. Interior system put in, sump pit cut, dry basement two springs running. Honest about the system being the right tool here.

Existing finished basement, leaks in three corners. They opened only what they had to, installed the tile and sump, closed it back up clean. The pump runs, basement is dry.

They explained why interior was the answer in our situation and not just upselling exterior. The system has worked through every melt since. Trust earned.

Battery backup pump was their recommendation and we are glad we listened. Lost power for a day this spring; basement stayed dry the whole time. Worth every dollar.
