Foundations, shop slabs and garage floors

Everything above it depends on the foundation. We pour footings, stem walls and slab foundations for shops, garages, additions and sheds, and the floors that go inside them.

Foundations & Slabs

What we do

We work with homeowners and with general contractors on bigger builds, and coordinate around weather and the other trades on site.

  • Footings and stem walls
  • Slab-on-grade foundations
  • Shop and garage floors
  • Shed and outbuilding pads
  • Foundations for additions
  • Large slabs and sport courts

Shop slabs, big and small

We pour a lot of shop slabs. One customer called their 56' × 26' slab "a super high quality product, on a fast timeline, at a fair price."

Built through the weather

On one shop project the crew "had to work against freeze, rain and other weather delays" to finish the stem wall, footing and slab before the end of the year.

“Rupp Construction & Concrete provided exceptional service on my 56’x26’ concrete slab project. Cameron was very responsive and a pleasure to work with during the process from initial inquiry through completion. They were 3-for-3 in providing a super high quality product, on a fast timeline, at a fair price. Highly recommended.”

“Cameron was very personable and honest with my spouse during the initial start of this shop project. He noticed a corner of our driveway was damaged by another team ( lots of team to make 1 shop) and said he would work with general contractor and make the repairs. Now I don't have the technical terms for the concrete slab, stemware wall, rebar. His crew had to work against freeze, rain and other weather delays, but got us finished at the end of the year 2025. My husband just said, "stem wall, footing and slab plus the corner of driveway repair". They are fast, open communication, Cameron was personable ( big thing as we are a family owned business too, and support other family owned businesses. Our neighbors always ask for referrals. Private neighborhood, so referral means we support them. We do not refer out often, so when we do, we are proud of the workmanship, prices, and personnel. Thank you.”

“We contacted Cameron to lay foundation for our shed, and he was able to submit a bid the next day. We didn't even need to get more because we knew we were in good hands from the consultation. We had an international vacation, but we were still able to trust Cameron to get our project done and do it right. By the time we returned it was done and looked amazing. We would definitely recommend Rupp to anyone.”
