Serving Greater Kyle

Concrete Slab

Concrete slabs and pads in Kyle, TX for shops, sheds, RV parking, generators and equipment, specified by the load they carry.

Kyle Elite Concrete builds the concrete slab in Kyle, TX for shops, shed bases, RV parking, generators and equipment, with more than 20 years behind the work, serving surrounding cities including Buda, San Marcos, Manchaca, Shady Hollow, Redwood. A slab is the piece of concrete where almost everything that matters is buried before the pour.

Once the concrete is down, nobody can see whether the subgrade was compacted, whether the base was brought to density, whether the vapor retarder was lapped correctly, or whether the bar was chaired at mid-depth or left lying on the ground. Those four things decide how the slab performs for its whole life.

That is why our proposals describe the layers rather than just the square footage and the thickness. A slab quoted purely on area invites the cheapest possible answer to every question underneath it, and on ground that moves the way Kyle’s does, those are the questions worth paying for.

What Goes Under a Slab

Subgrade Preparation and Compaction

The subgrade is stripped of organics and soft material, shaped to the right elevation, and compacted to a specified proctor density rather than to whatever a plate compactor achieves in one pass. Utility trenches crossing the footprint get particular attention because loose backfill is a settlement waiting to happen. We test rather than assume, and we record what we got.

Flexible Base Course and Thickness

Over the subgrade goes a compacted flexible base, which spreads load, gives a working platform and provides drainage under the slab. Its thickness is part of the design, not a leftover. Cutting base thickness to save money moves stress into the concrete, which is the more expensive place for it to end up.

Vapor Retarder and the Capillary Break

Where a slab will be enclosed, heated, or finished with anything that dislikes moisture, a 10 mil vapor barrier meeting ASTM E1745 goes under it as a capillary break. Laps are sealed and penetrations detailed, because a barrier with gaps is not a barrier. Slabs poured without one are the reason so many shop floors sweat and so many coatings fail.

Reinforcing and Slab Types

Slab on Grade With Deformed Bar

The standard build here is a slab on grade reinforced with deformed bar tied into a mat and set on chairs at mid-depth, sized to the loading. Bar carries load across a crack once one forms, which is what keeps a cracked slab acting as one piece. Where a slab is lightly loaded, the bar layout gets lighter rather than disappearing.

Post Tensioned Slabs and Tendons

On expansive ground a post tensioned slab is often the engineer’s answer, using tendons stressed after the concrete gains strength to keep the whole slab in compression. Designed to PTI DC10.5, it tolerates the seasonal movement Kyle’s clays produce better than a conventionally reinforced slab of the same thickness. This is engineered work, and we build it to the sealed design rather than adapting it.

Monolithic Pours, Turndown Edges and Footings

A monolithic pour places the slab and its thickened edge in one operation, with a turndown edge or an integral footing carrying the perimeter load. It is quick and it removes a cold joint at the most vulnerable line. Where loads or soil conditions call for separate footings, grade beams or piers, those get formed and poured on their own schedule.

Slabs and Pads We Build

Shop Floors and Workshop Slabs

A working shop floor takes point loads from jacks and equipment feet, rolling loads from tool chests and vehicles, and chemical exposure from whatever gets spilled. Thickness, joint layout and surface finish all follow from that. We ask what the floor will actually do before specifying it, including whether it will ever take a coating.

RV Pads, Generator Pads and Equipment Pads

An RV pad concentrates heavy axle load onto the same strip every time and needs thickness and reinforcing at the wheel path rather than uniformly. A generator pad is a static load with anchorage and vibration to consider. Equipment pads vary enormously. These are sized individually, because a single default thickness either wastes concrete or fails.

Shed, Storage and Container Pads

Shed and storage building slabs are usually straightforward, but the edge detail matters because that is where the structure attaches and where water arrives. Container pads take a punishing point load from delivery trucks and from the container corners themselves. Where no local standard detail exists for them, we build to ACI 330 guidance for the loading involved.

Engineering, Permits and Kyle’s Soils

When a Sealed Engineer Design Is Required

Foundation work in Kyle is engineered and permitted, and the city states the reason in its own words as the expansive soils in Kyle. That means a sealed engineer letter driving the design rather than a contractor’s rule of thumb. We work to that design, and where a slab you are planning will cross into that territory we say so early rather than after a permit is refused.

Sizing a Slab to Its Actual Load

Thickness, bar size and spacing, and joint layout are all consequences of load, and load is a question with a specific answer for your slab. A 4 inch shed base and a slab carrying a loaded trailer are not the same design with different dimensions. We would rather ask several questions at the estimate than guess and be wrong in either direction.

Curing a Large Pour in Texas Heat

Big slabs have a lot of surface relative to their volume, and in Kyle heat the evaporation rate at that surface easily outruns bleed water, which is what produces plastic shrinkage cracking. We plan pour timing, use an evaporation retarder and either wet cure or a curing compound, and sawcut control joints early enough to be useful. The cure is a scheduled operation, not an afterthought.

Our Step-by-Step Concrete Slab Process

Load, Use and Site Assessment

We start with what the slab is for, what will sit or drive on it, and what the ground is under it. Drainage and finished elevation get set at the same visit. What comes back to you is a layered specification rather than a price per square foot.

Forming, Base and Reinforcing

Forms go in to the agreed elevation and slope, the subgrade and base are built and compacted to density, and the vapor retarder is laid and sealed where the slab calls for one. Reinforcing is tied and chaired to mid-depth. We ask you to look at this stage, because it is the last time any of it is visible.

Placement and Finish

Concrete is placed to full thickness, consolidated, screeded and finished to whatever the slab needs, from a broom finish outdoors to a hard trowel finish on an interior floor. Finish choice follows use rather than habit. Control joints are sawcut on a spacing matched to thickness before the slab decides for itself.

Cure and Return to Service

The cure is run deliberately with the method chosen for the day’s conditions, and the slab is protected while it gains strength. We give you separate dates for foot traffic and for full load, since they are not the same. Batch tickets for what was delivered are handed over with the job.

Frequently Asked Questions

How thick does my slab need to be?

It depends entirely on what will be on it. A shed base, a shop floor taking rolling equipment and an RV pad carrying a heavy axle in the same wheel path are three different designs, not one design at three prices. Thickness, bar size and spacing, and joint layout all follow from the load. We ask what the slab will actually do before specifying it.

Do I need a vapor barrier under a slab?

If the slab will be enclosed, heated, or finished with flooring, a coating or anything moisture sensitive, then yes. A 10 mil vapor barrier meeting ASTM E1745 acts as a capillary break so ground moisture does not migrate up through the concrete. Skipping it is the reason a great many shop floors sweat and a great many coatings later peel off.

What is a post tensioned slab and do I need one?

It is a slab kept in compression by steel tendons stressed after the concrete has gained strength, and on expansive clay it handles seasonal ground movement better than conventional reinforcing at the same thickness. Whether you need one is an engineer's call, not ours. Where the design calls for it, we build to the sealed drawings and the relevant PTI guidance.

Does a slab need a permit in Kyle?

Some do and some do not, and the deciding factor is usually whether it is structural, whether a building goes on it, and whether it touches the right of way. Foundation work is engineered and permitted here because of the expansive soils the city names in its own ordinances. We identify what your specific slab needs before starting rather than after.

Why do slabs crack?

Concrete shrinks as it cures and it has almost no tensile strength, so some cracking is expected rather than avoidable. The job of the design is to control where it happens, using sawcut control joints at the right spacing, and to keep the slab acting as one piece afterward, which is what the reinforcing does. Uncontrolled cracking usually traces to joints cut late or spaced too far apart.

Can you pour a slab in summer?

Yes, and most of our slabs go in during warm weather. It changes how the pour is run rather than whether it happens: earlier starts, an evaporation retarder on the surface, a curing method chosen for the conditions, and joints sawcut on time. Hot weather concreting is a set of procedures, and the alternative to following them is plastic shrinkage cracking.

Can you pour a pad next to an existing building or slab?

Yes, with an isolation joint between them so the two can move independently. Tying a new pad rigidly to an existing structure transfers movement from one to the other, and on Kyle's clays that movement is guaranteed. We detail the joint and, where the new pad affects drainage against the building, we deal with that at the same time.
