When the soil around a basement stays wet, water works its way through cracks and joints in the wall. Delpres Services does foundation waterproofing and crack repair from the outside, where that water arrives. We dig down to the footing and repair the cracks first. Then a membrane goes on the wall, with dimple board and footing drain tile to carry water away.
We are based in Harrison Township and work across Macomb County, Oakland County, St. Clair County and Wayne County. Exterior basement waterproofing is dig work first, and it draws on our excavation and site work. We look at the walls and the grade, then put a free estimate in writing. Call (877) 633-5773 to set up a visit.

Much of Macomb County sits on wet, heavy ground. USDA soil survey data rates most of the county as very limited for homes with basements. The main reason it lists is saturated soil close to the surface.
Lenawee, one of the county's most common soils, is clay-rich ground left by old lakes. Its USDA description says water often stands on it from November to May.
Heavy clay and a high water table both build water pressure against a basement wall. Building codes typically call for waterproofing where that pressure can occur. Dampproofing covers walls where that pressure will not occur.
Every dig starts with a call to MISS DIG 811, so buried utility lines get marked. Then we excavate along the wall down to the footing. With the wall open, cracks get repaired before anything covers them.
Next, a liquid or sheet membrane goes on the wall. Dimple board goes over the membrane and gives water a path down to the footing. There, footing drain tile carries it to an outlet, such as a storm sewer or lower ground. When that outlet needs a new line, our storm drain and catch basin work covers it.
We backfill in lifts and compact each one, then shape the grade so water runs away from the house. Masonry industry guidance calls for a drop of at least 6 inches in the first 10 feet. Last, we restore the lawn and any concrete or asphalt we disturbed.
A crack in a basement wall is a path for water. With the wall dug open, we repair it from the outside, where the water gets in. The membrane then covers the repair along with the rest of the wall.
Some cracks point to a bigger problem. A home inspectors' association links horizontal cracks to saturated soil that pushes a wall inward. A bowing wall or a long horizontal crack is a question for a structural engineer first.

We visit the site and check the access and the ground. The estimate comes to you in writing.
We call MISS DIG 811 for utility locates before any digging. On septic jobs, we line up our work with the county's soil evaluation and inspections.
We dig to spec with equipment sized to the site. Then the work goes in to the approved plan or the agreed scope.
After the required tests and inspections, we backfill and restore what we dug up. Lawns get topsoil and seed or sod, and paved areas get new concrete or asphalt.
Common questions about foundation waterproofing around Macomb County and the rest of Metro Detroit. If yours is not here, call or text and ask.
We pour footings, foundation walls and slabs for homes, additions, garages and light commercial buildings across Macomb County. We work with general contractors and direct clients, and every foundation is poured to code.

We install storm drains, catch basins, manholes and culverts for residential subdivisions and commercial sites. Every line runs on a steady slope to its outlet, and we restore the ground after.

Basement and pool digs, utility trenches, site grading and prep for slabs and drives across Macomb County. We call MISS DIG before we dig and backfill in compacted lifts.
Learn MoreMini-excavators reach tight residential lots, and full-size equipment handles deep commercial digs. Each job gets a machine sized to its access and depth.
Required tests on new lines, such as pressure tests or camera inspections, are done and documented before final backfill. Then we compact the backfill in lifts.
