Exterior waterproofing Sussex homeowners actually trust

When a basement wall keeps leaking, the water is coming from outside the foundation, and that is where the real fix belongs. Exterior waterproofing seals the outer face of the wall and drains the water away at the footing, so it stops before it ever reaches your Sussex basement. It is the most thorough way to keep a basement dry, and it is the right call for a chronic leak or a finished space you want to protect.

Sussex is a growing village in the Lisbon area, sitting near the headwaters of the Fox River. The ground here is glacial clay, and that clay holds water. Every spring the snowmelt saturates it, the soil swells, and it presses against your foundation walls. The village mixes older block-foundation homes with newer subdivisions, and both feel it. The older block walls tend to leak at the cove joint and through cracks in the block, and interior patches only cover the inside while the block stays wet.

We run our shop out of 2128 Easy St in nearby Waukesha, and Nick, Luis, and our own crew have been sealing these walls since 1998. During a free inspection we find where the water is really getting in, dig along that wall, seal it, and drain it, then back the work with a lifetime transferable warranty. One homeowner we worked with had fought a wet wall for years. We sealed the outside, and the basement stayed bone-dry straight through the next spring thaw.

How We Waterproof It in Sussex

Proven exterior waterproofing built for Sussex

Excavation down to the footing

We dig carefully along the leaking wall to expose it top to bottom, all the way to the footing, so the full face can be sealed. In the glacial clay around Sussex this is slow, deliberate work.

Liquid waterproof membrane

After cleaning the wall and patching cracks with hydraulic cement, we coat the whole surface with a thick elastomeric membrane that seals the water out for good.

Dimple board + weeping tile drainage

A dimpled drainage board gives water an air gap to fall down, and perforated weeping tile at the footing collects it and carries it away from your home.

Washed gravel backfill & regrading

Clean washed gravel wraps the weeping tile for fast drainage, then we backfill the soil and re-grade so the surface slopes water away from the foundation.

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.

Sussex exterior waterproofing FAQs

The glacial clay under Sussex holds water, and when the spring snowmelt saturates it the soil swells and presses on your foundation. That pressure pushes water through cracks and the cove joint. Exterior waterproofing seals the wall outside and drains the water at the footing so the spring soak has somewhere to go.
Often yes. If the leak keeps coming back through one Sussex wall, we only excavate along that wall and seal it from the outside, which keeps the cost down and the rest of your yard alone. During the free inspection we confirm the water really is coming through that wall so we seal the right spot.
We only dig along the affected foundation wall and leave the rest of the property alone. We protect the surrounding area while we work, then backfill with washed gravel and soil and re-grade so water slopes away. Grass and plantings can be replaced, and our own crew handles the digging so the site stays under control.
Most jobs run a few days, depending on how much wall we open up and how easy the yard is to reach with equipment. The glacial clay around Sussex is slow to dig, and we build that into the timeline you get in writing before we start.
Yes. Older block homes in the Lisbon area leak at the cove joint and through cracks in the block because the block soaks up water from outside. We seal the wall face and drain it at the footing, so the block stays dry and the water is carried safely away from the house.
Both keep a basement dry, and the right one depends on your home. Exterior waterproofing stops water at the wall and is the most thorough fix, which is worth it for a finished basement or a chronic leak. Interior drain tile is less invasive and easier on the budget. We give you an honest recommendation at the free inspection.
It depends on how long the wall is, how deep the footing sits, and how easy it is to get equipment to the dig. Because it involves excavation it runs more than an interior system, and you get an honest written quote after a free in-home inspection, with no guessing over the phone.
