BJ Construction LLC is a family-owned concrete contractor based in Green Lake, WI, serving communities across central Wisconsin. From Oshkosh to Montello and everywhere in between, we bring the same crew, the same standards, and the same commitment to every job. One company, one team, no subcontractors.
Central Wisconsin's mix of lakefront lots, rolling farmland, and in-town parcels means no two foundation jobs are alike. We pour residential and agricultural foundations engineered for the specific soil and grade conditions at your site, from sandy glacial ground near the lakes to the heavier clay soils inland.
We pour driveways, sidewalks, aprons, and parking pads for homes and businesses across central Wisconsin. Every slab is built with proper sub-base preparation and control joints placed to handle the freeze-thaw cycles that define our winters. We serve Green Lake, Ripon, Oshkosh, Fond du Lac, and every community between.
Whether it's a two-car garage in Waupun, a farm shop near Princeton, or a pole barn floor outside Markesan, we pour garage and shop slabs built for heavy use. Proper slope, drainage, and reinforcement are standard on every job we do across the region.
Stamped concrete patios, walkways, and pool surrounds are our specialty. Homeowners from Oshkosh to Montello choose our decorative concrete for outdoor living spaces that look like natural stone at a fraction of the cost. Preview patterns on your own home with our free visualizer before we pour.

We build poured concrete retaining walls that hold slopes, prevent erosion, and create usable yard space on uneven terrain.
Wisconsin winters are hard on concrete. We repair cracked driveways, settled stoops, spalled sidewalks, and deteriorating patios across the region. If your concrete is failing, we'll diagnose the cause and fix it right rather than just patching over the problem.
We're based in Green Lake, and our service area covers a roughly 30-mile radius that includes Green Lake County, Fond du Lac County, and parts of Winnebago, Marquette, and Waushara counties. That's not a corporate franchise drawing a circle on a map. It's the territory we actually work in, know well, and can reach quickly for site visits, material deliveries, and curing checks.
Being a single crew that covers the whole region means you get consistency. The same people who poured a foundation in Ripon last week are the ones forming your driveway in Berlin this week. No rotating subcontractors, no surprises. We bring our own equipment, our own standards, and our own reputation to every job site from Oshkosh to Montello.
Central Wisconsin's building conditions vary meaningfully from town to town. Lakefront properties around Green Lake and Fond du Lac deal with high water tables and sandy soils. Inland communities like Markesan and Princeton sit on heavier agricultural ground. Oshkosh and Waupun have established neighborhoods where access and setbacks matter. We've poured concrete in all of these conditions and know what each one demands.
