On the South Plains, a shop is the heart of a lot of properties. Farm shops, ranch barns, metal buildings and backyard workshops all need a floor that can take trucks, tractors, welders and dropped tools. A dirt floor turns to dust in the wind and mud in the rain. A good shop concrete floor is flat, tough and easy to sweep.
Lubbock Concrete pours a shop concrete floor and barn floors in Lubbock, TX and across the South Plains. We pour inside existing buildings or coordinate with your builder on new ones, and we give a free written estimate.
What a shop concrete floor needs underneath
A floor is only as good as what is under it. We grade the soil, add and compact base material and lay a vapor barrier where moisture is a concern. Steel rebar or heavy mesh, and sometimes fibers, controls cracks. The slab edges are thickened where wheels turn and where the walls sit.
Thickness depends on use. A hobby shop with cars and tools does well at four to five inches. A shop with a lift, a loader or loaded trucks needs six inches or more. Tell us what rolls across the floor and what sits on it.
- Compacted base and a vapor barrier where needed
- Steel or fiber for crack control
- Four to six inches or more for heavy use
- Joints cut at the right time to guide cracks

Finishes for shop and barn floors
A hard steel trowel finish is smooth and dense, easy to sweep and easy to seal. A light broom finish adds grip where it gets wet or where animals walk. A sealer or hardener keeps oil from soaking in and keeps dust down, which is a real help when wind blows dust through open doors.
In barns, drainage matters. We can slope the floor toward a drain or a door so wash water leaves. Edges near gates may need extra thickness against tires and hooves.

Pouring inside existing buildings and farm lots
Most shop floors in our area are inside metal buildings that are already standing. We work with smaller equipment, a pump or a wheelbarrow route, protect the walls and pour in sections if the doors are narrow. We set the floor height to match door sills.
On rural lots, we plan the truck route, check gates and ground, and match the slab to the building plans. See concrete slabs, garage floor concrete and RV pad concrete for related work.

Shop concrete floor cost, timing and next steps
Price depends on size, thickness, steel, finish and how easy it is to get a truck inside. A two car shop can often be poured in one day, followed by about a week of cure before heavy items move in. Full strength takes four weeks.

Shop and Barn Concrete Floors questions answered
How thick should a shop concrete floor be?
For a hobby shop or home garage with cars, tools and a workbench, four to five inches is common. If you use a car lift, a heavy press or a tractor, or park a loaded truck inside, we suggest six inches or more with steel to match. The load under each wheel or lift post matters more than the total weight in the building.
A great shop concrete floor is more than thickness. The base needs to be compacted, and we often add a vapor barrier. Steel keeps cracks tight. If your lift maker lists a minimum slab thickness and strength, we follow it. Tell us what you plan to put on the floor, and we will design for it. Cold snaps can arrive quickly in winter, and fresh concrete must never freeze, so we watch the overnight lows before every pour. A walk through your yard after a heavy rain shows where water really goes, and it helps us design the slope correctly.
What is the best finish for a shop floor?
A hard steel trowel finish is the most popular for indoor shop floors. It makes a dense, smooth surface that is easy to sweep and wipe, and it stands up to tires and tools. It also gives a nice base for sealers or epoxy later. If your floor will often be wet, like when you wash equipment or animals, a light broom texture adds safety.
In barns, many people choose a broom finish because boots and hooves need grip. We can slope the floor toward a drain or a door so water leaves quickly. Let us know how you use the space, and we will choose a finish that stays safe and easy to clean. The more we know about your plans, the better we can design the slab, so share your ideas even if they are not final. Keep roof water and sprinkler spray away from the edges of your slab, since wet soil next to concrete is a common cause of movement.
Will my shop floor crack?
Almost all concrete cracks a little, and that is normal. The goal is to control where it cracks and keep the cracks tight. We do that with a good base, steel or fiber and control joints, which are shallow saw cuts placed in a grid. The joints give the concrete a planned line to crack along.
We cut the joints at the right time, usually the next morning, before the slab cracks on its own. We also cure the concrete well, since West Texas wind dries concrete fast. If a crack shows up later, small ones can be filled with a flexible sealant. We explain what to expect when we finish. If the forecast turns bad the night before, we call and reschedule, because a short delay is better than a damaged slab. Texas heat can push concrete to set faster than expected, so we bring extra hands and plan the finishing order before the truck arrives.
Can you pour a floor inside an existing metal building?
Yes. Many of our shop floor jobs are inside buildings that are already up. We use smaller equipment, a pump or a wheelbarrow route, depending on the door size, and we protect the walls. If the ground inside is low, we bring in base material and compact it. If the building has a perimeter footing, we tie the slab to it as the design allows.
For best results, tell us the door sizes and clearances before we come. We can also add anchor points for lifts and benches while we are there. Ask for a free estimate and we will walk through the plan. If you have an HOA, get approval in writing before the pour, and we will help with a simple sketch and finish samples. We keep the same crew on your job from start to finish whenever we can, so the people who plan it also build it. Please call with any question, large or small, because we would rather answer it now than have you wonder.
How do I keep oil and chemicals from staining a shop floor?
The best way is to seal it. A good sealer or hardener fills the pores in the concrete, so oil, grease, antifreeze and brake fluid sit on top and wipe away. Without sealer, those liquids soak in and leave dark spots that do not come out.
We can apply a penetrating sealer, a film forming sealer, or a heavier epoxy or polyurethane coating, depending on your needs. Clean spills fast, use a degreaser on old stains and avoid strong acids. Keep a drip pan under leaky engines. A sealed floor is easy to maintain and still looks decent after years of real use. Tell us what will sit on the slab or drive across it, since the weight on each wheel decides how thick the concrete should be. Rinse oil, grease and fuel spills off concrete as soon as you can, because they soak in and stain over time. Fresh concrete is alkaline and can irritate skin, so keep kids and pets away and wash off any wet concrete right away.
How long before I can move equipment into a new floor?
You can usually walk on it after a day or two. Light tool chests and shop equipment can go in after about seven days. Wait about 28 days before you set heavy lifts, big presses or loaded trucks, because the concrete is still gaining strength in the first month.
If you must move something sooner, tell us. In some cases, we can use a stronger mix or adjust the schedule so more of the floor is ready sooner. We tell you exactly when the floor is ready for each stage, and we leave care instructions so the slab keeps its strength. Do not use de icing salt on new concrete, because it can scale the surface, and a little sand gives traction without harm. The first week after the pour is the most important time for the concrete, so a little patience then pays off for decades. We follow the plans for steel size and spacing, and we use chairs to hold rebar off the dirt so it ends up in the middle of the slab.
