Foundation and waterproofing work in Greenfield
A typical Greenfield basement is concrete block laid up in the 1950s or 60s under a ranch or a Cape Cod. Those walls have seen sixty-plus Wisconsin winters, and many show it with stair-step cracks running up the mortar joints. That pattern usually means the clay outside has been pushing, and some walls have started to lean in. Add an original sump pit, a tired pump, and maybe old clay tile that silted up long ago, and you get the basement a lot of Greenfield owners call us about.
We start with the block itself. Stair-step cracks get sealed, and a wall that's moving gets carbon fiber straps or steel I-beams anchored at the floor and joists. Then we take on the water. That can mean new interior drain tile under the slab to a modern sump pump with battery backup, or excavating outside to the footing for membrane, dimple board and new weeping tile. We also seal walls, add vapor barrier, and cut egress windows for a legal bedroom. When the City of Greenfield requires a permit, we pull it.
