Concrete floors turn up in Oakland garages, basements, workshops, shops, restaurants and the many converted warehouses and lofts near the waterfront. A new floor slab needs a firm base, a vapor barrier under any area that will be enclosed or covered with flooring, and joints placed to control cracking.
Moisture is the thing to plan for. Slabs in low areas near the estuary and slabs cut into a hillside can draw water up from the ground. That shows as a white powder on the surface or as flooring that lifts. A proper barrier under a new slab prevents it. On an existing floor we test for moisture before any coating or covering goes down.
For the surface you can have a steel-trowel finish, a light broom for grip in a garage, a sealed finish, or a ground and polished floor. We also pour sloped floors with drains for wash-down areas and commercial kitchens.
Concrete floors in Oakland: common questions
Can you pour a new floor over my old garage slab?
Sometimes a bonded topping works if the old slab is solid. If it is cracked, sunk or damp, removing it and pouring a new slab on a good base is the lasting answer.
Why is there white powder on my floor?
That is mineral salt left behind when moisture moves up through the slab and dries. It tells you water is coming through. The fix starts with finding where the water is coming from.
Is a concrete floor cold?
It feels cool, which many people like in a loft or shop. Rugs, radiant heat in a new slab, or an insulated layer under it are the ways to change that.
