A floor that wears well comes down to good timing on pour day, so we plan the finishing, joint cutting and curing ahead of time instead of rushing it. First we dig out and pack the subgrade, the ground the slab sits on, because a base that's only raked level settles with the dirt and takes the floor down with it. If a budget has to give somewhere, I'd rather trim the finish than the base, since nobody can fix the ground work once there's concrete on top. Next we set forms, check how water drains around the slab, lay the layer that goes under the concrete and place rebar, the steel bars that hold a slab together, wherever the floor calls for it. We pour early, before midday heat dries the top too fast and leaves it weak and dusty, then finish the surface and cut control joints, shallow cuts that give the concrete a planned place to crack as it shrinks. Then comes curing, the wait while the concrete gains strength, and you'll get a plain answer on when you can walk on it and when it's ready for heavier things.
A new floor often sits next to other concrete work. If a door ends up higher than the yard, we can pour concrete steps to match, and if the project runs out toward a pool, we build concrete pool decks with the same care for the base and the joints.
A floor that will get flooring or a coating
This suits a room, studio or office where tile, vinyl, wood or a coating goes on top later. We put extra care into what sits right under the slab and how it's protected during the pour, because moisture coming up through concrete is what ruins flooring.
A bare working floor
This suits a workshop, storage building or utility space where the concrete itself is the surface you walk and work on. The focus is a hard, even top and joints in planned spots, since there's nothing laid over it to hide a dusty or cracked surface.
A reinforced floor for heavier use
This suits floors that will carry machines, heavy shelving or a small business's daily traffic. Steel in the slab adds some cost, but it holds the concrete together and keeps any crack tight, which matters when the loads are heavy.
