Foundation and waterproofing work in Sussex

In Sussex, the clay decides a lot. The village sits on heavy glacial clay in northern Waukesha County, next to Lisbon, and every spring that clay soaks up snowmelt, swells and leans on the foundation. Older homes here tend to have block walls, which answer that push with stair-step cracks and slow bowing. The newer subdivisions went up on poured concrete, which tends to show vertical cracks and seep at the joint where the wall meets the floor. Different walls, same pressure behind them.

We come up from our shop in Waukesha and have been doing this since 1998. Our crew handles the full range for Sussex homes: sealing cracks, bracing bowing block with carbon fiber straps or steel I-beams, interior drain tile to a sump crock with battery backup, exterior waterproofing down to the footing, wall sealing with a vapor barrier, and egress windows for a legal bedroom. Structure gets fixed first, then water. When the Village of Sussex requires a permit, we pull it.

Every basement service we offer in Sussex

Foundation Repair in Sussex

Each crack is cleaned out and packed with hydraulic cement and structural sealant, which shuts off both water and movement at that spot.

What homeowners say about our crew

★★★★★

They replaced our drain tile, put in a sump pump, set steel beams, and sealed the basement walls - then redid the window wells and buried a downspout outside. The price was competitive and Nick, Luis and the crew explained everything as they went.

Questions, Answered

Sussex basement questions

Very likely. Heavy clay swells with snowmelt and pushes water through any gap it can find. We trace where it comes in and fix that wall first.
Not always. Early bowing can be held with carbon fiber straps. If the wall has moved further, steel I-beams anchored at the floor and joists are the right call.
That joint seepage is what interior drain tile handles. We trench under the slab along the walls and run the water to a sump pump with battery backup. Your yard stays untouched.
Yes. Sussex and Lisbon are both regular stops for our crew out of Waukesha. Same-week appointments are common, and permits go through whichever community covers your address.
It usually takes a day or two. We cut the opening, set a code-compliant window and well, and tie in drainage. When the Village of Sussex requires a permit, we pull it.
Structure first. A moving wall will keep cracking any waterproofing put on it. Once it's stable, we deal with the water.
It relieves a lot of it. We dig to the footing, membrane the wall, add dimple board and new weeping tile in washed gravel, and grade the backfill. Water drains away before it builds pressure.
Often it is. Concrete passes moisture as vapor even when you see no water. Wall sealing and a vapor barrier cut the dampness and the smell.
Same-week appointments are common. Call the shop and we'll set up a time that fits your week.
Yes, financing is available. Ask when you get your written quote and we'll go over the options.
