Below-Grade Concrete in Detroit, Sealed Against Water
A basement only becomes usable space when groundwater is managed first. Detroit Concrete handles waterproofing, seals active cracks, pours level floors and builds walkout exits so your below-grade area stays dry and ready for finishing. From renovation slabs to foundation work, we start with water control. Free written estimate on every project.
Groundwater pressure in Detroit's clay soil pushes against foundation walls year-round. Without proper sealing and drainage, that water finds cracks and seeps under the slab, ruining finished flooring and creating mold conditions. Foundation waterproofing and crack sealing stop water at the source before any concrete floor is poured.
Once the basement is dry, the slab can be installed correctly. A level basement floor with a proper vapor barrier and slab detail gives you a stable base for finished flooring, storage, or living space. The concrete itself becomes part of the moisture control system.
For larger projects, basement renovation concrete includes slab repair, leveling, and detail work that finished basements require. A walkout basement adds a grade-level exit with new footings and drainage, turning a dark space into a bright room. All of it depends on the foundation staying dry.

Our approach
The Basement Concrete Process in Detroit
Assess moisture and damage
We inspect walls, floor, and perimeter drainage to identify where water enters, which cracks are active, and what sealing or waterproofing is needed.
Seal and waterproof
Active cracks are injected, walls are sealed or membraned, and drainage is restored so groundwater is directed away from the foundation.
Prepare and pour
The sub-base is prepped, a vapor barrier is laid, and the basement floor is poured or resurfaced level and true to the correct slab detail.
Cure and transition
The slab cures, we walk the space with you, and you receive care instructions and the timeline for finished flooring or next trades.

Walkout and Renovation Basement Concrete
A dry basement opens possibilities. Basement renovation concrete handles the slab repair, leveling, and detail work that finished basements need before drywall and flooring are installed. The concrete becomes the foundation for the entire finished space.
A walkout basement is a larger undertaking: cutting a grade-level exit into the foundation, installing new footings, building steps, and tying in drainage so a below-grade room gains natural light and direct yard access. The basement floor and waterproofing must be solid first, which is why we sequence the work carefully. Both projects rely on a dry, level slab as the starting point.
Waterproofing, floors, cracks and walkout work for basements in Detroit.
Yes. Waterproofing and drainage come before any finished surface, because water under or behind a slab will find every shortcut. We deal with where water gets in first, then pour the floor.
Usually. A basement floor can often be resurfaced or re-poured flat over a prepared sub-base, with crack repair first where cracks are active. We confirm the cause before recommending a fix.
A walkout basement means cutting a grade-level exit into the foundation, with new footings, steps, drainage and slab detail to match, so a below-grade level gains daylight and direct yard access.
Spring melt raises the water table and pushes against the foundation. Seasonal leaks usually mean cracks plus a drainage problem, both addressed together with crack repair and waterproofing so the fix holds.
Yes. Basement renovation concrete covers the slab repair, levelling, vapour barrier and detail work that has to be right before framing and finished flooring go in.
