Exterior waterproofing Greenfield homeowners actually trust

When a basement wall keeps letting water in, the water is coming from the outside, so that is where the real fix belongs. Exterior waterproofing seals the wall on its outer face and drains the water away at the footing, so it is stopped before it ever reaches your Greenfield 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.

Greenfield grew up after World War II as a Milwaukee suburb along the Root River corridor, and a lot of the housing stock is 1950s ranch and Cape Cod homes on block foundations. Those walls are now past sixty years old, and the mortar joints have opened up. The clay soil under these yards holds water and swells in spring. When the snow melts and the summer storms roll through, groundwater rises against the basement walls and works its way through the seams in the block.

We are based at 2128 Easy St in 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 near the Root River had fought a wet wall for years; we sealed the outside and their basement stayed bone-dry straight through the next spring thaw.

How We Waterproof It in Greenfield

Proven exterior waterproofing built for Greenfield

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 Greenfield clay 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 out the water 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.

Greenfield exterior waterproofing FAQs

The clay soil under most Greenfield yards holds water like a sponge. When the snow melts and the ground thaws, that soil stays saturated for weeks and presses on the block wall until water finds a seam. Exterior waterproofing seals the wall face and drains the water at the footing, so the wet season passes without a leak.
For a lot of the 1950s ranches and Cape Cods around Greenfield, yes. Those block foundations are past sixty years old and the mortar joints have opened up. Sealing the outside of the wall covers those seams and stops water at the source, which is why it holds on homes that have leaked for years.
We dig only along the wall that leaks and leave the rest of the lot alone. We protect the area around the trench while we work, then backfill with washed gravel and soil and re-grade so the ground slopes away. Grass and plantings can be put back, and our own crew runs the machine so the site stays under control.
That is the whole point. Sealing the outside of the wall and setting weeping tile at the footing means the snowmelt that soaks Greenfield clay every spring drains away before it can push through. One homeowner near the Root River corridor stayed bone-dry the first spring after we sealed the outside.
Usually yes. Patches and sealers on the inside cover the face you can see, but the block stays wet from the outside and water finds a new path in. Exterior waterproofing seals the outer wall and carries the water away at the footing, which is why it holds after inside fixes have failed.
Most jobs run a few days, depending on how much wall we open and how easy the yard is to reach with equipment. Greenfield clay digs slower than sandy soil, and we build that into the timeline you get in writing before we start.
It comes down to 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.
