Concrete Slab & Add-On Contractor Across Dallas–Fort Worth
A slab is the most versatile thing we pour and the one where base prep matters most, because a slab is almost always carrying something — a shop, a carport, a hot tub, a trailer, a metal building, or just the corner of your house where you decided the patio should have been bigger. Get the ground underneath it wrong and the load finds that soft spot within a year.
The work splits into two kinds. A standalone pad — shop, shed, RV parking, generator, dumpster — gets sized on thickness and reinforcement for what is going on top of it, with a thickened edge or beam where a structure will be anchored. An add-on poured against existing concrete is a different problem: two slabs that meet have to be tied together or deliberately isolated, or the joint between them opens into a lip within a couple of seasons.
We drill and epoxy dowels into the existing slab so the new pour moves with the old one instead of independently, match the finish and joint pattern as closely as concrete honestly allows, and set the grade so the seam is not collecting water against your foundation. That tie-in is the single most common thing we get called back to fix on somebody else's add-on.
Patio extensions, slab add-ons, shop and building pads, RV and boat parking, and equipment pads all run through the same crew. Call 972-921-9488 for a free measure.
Signs You Need This
- A patio or driveway that is simply too small for how you use the space
- An existing add-on with an open joint or a lip where it meets the old slab
- A shed, shop, or hot tub currently sitting on dirt, gravel, or pavers
- Ruts and mud where an RV, trailer, or work truck parks
- A slab corner that has settled or cracked under concentrated weight
- Water pooling at the seam between two pours instead of draining off
Concrete Slab & Add-On Contractor Services
Residential and commercial work throughout the Dallas–Fort Worth metroplex. No job too big or too small.
Patio Extensions & Slab Add-Ons
More usable space poured against the existing patio or driveway, doweled in so the two slabs move together and finished to match as closely as possible.
Shop, Shed & Building Pads
Pads for metal buildings, garages, carports, and workshops — with thickened edges or perimeter beams where the structure gets anchored down.
RV, Boat & Trailer Pads
Thicker slabs with heavier reinforcement sized for concentrated axle and tongue-jack loads, graded so water does not sit under the unit.
Hot Tub & Pergola Pads
Level, reinforced pads sized for the filled weight of a spa or the post loads of a cover, not just the footprint of the thing sitting on it.
Equipment, Generator & Dumpster Pads
Commercial and residential pads for HVAC units, standby generators, and dumpster enclosures, poured to the spec the equipment requires.
Floating Pads & Pad Walkways
Separate poured squares set in rock or ground cover for a modern backyard look, each formed and reinforced individually so they stay flat.
Our Concrete Slabs & Add-Ons Process
Free on-site measure
We look at what is going on the slab, how heavy it is, how water crosses the site, and where the truck can reach — then hand you a written price.
Excavation and haul-off
Sod and soft material out and off the site. On an add-on we also expose the edge of the existing slab so we can see what we are tying into.
Base build and compaction
Subgrade compacted, and base material brought in and compacted where the native soil will not hold a uniform bearing surface.
Forming and dowel tie-in
Forms set to line and grade. Against existing concrete we drill and epoxy dowels into the old slab so the new pour is mechanically connected.
Reinforcement sized to load
Rebar grid on chairs — not dropped on the dirt — at spacing and thickness set by what the slab is going to carry.
Pour, finish, joint, cure
Placed, screeded, floated, and finished to the texture you want. Control joints cut to continue the existing pattern where there is one.

Concrete Slabs & Add-Ons FAQ
How much does a concrete slab cost in Dallas–Fort Worth?
+
It comes down to square footage, thickness, how much reinforcement the load requires, and how much excavation and haul-off is involved. A thin patio add-on and an RV pad of the same size are not the same job. We measure on site, tell you what thickness the use actually calls for, and give you a free written estimate we will hold to. Call 972-921-9488.
Can you pour a new slab up against my existing patio or driveway?
+
Yes, and that is most of what we do. The important part is the tie-in: we drill into the edge of the existing slab and epoxy dowels in, so the new concrete is pinned to the old one and both move together. Poured without dowels, the two slabs settle independently and you end up with a lip and an open joint you can put a finger in.
Will the new concrete match the old?
+
Close, but it will not be identical, and anyone who promises otherwise is overselling. Cement color varies by batch and the existing slab has years of weathering on it. We match the finish texture and continue the joint pattern so it reads as intentional, and the color difference narrows considerably over the first year.
How thick does a shop or RV slab need to be?
+
A four-inch slab is fine for foot traffic, patios, and passenger vehicles. Shops, metal buildings, RVs, and loaded trailers get thicker concrete with heavier rebar, and usually a thickened edge or perimeter beam where the building anchors down. We size it for the actual load rather than pouring everything the same.
Do I need a permit for a slab or patio extension?
+
It depends on your city and on what is going on top. A flat patio extension often does not require one, while a slab intended to carry a structure frequently does, and HOA approval is a separate question from city permitting. We will tell you what applies to your address when we come out.
How do you keep an add-on from sending water toward my house?
+
By setting the grade before anything gets poured. A new slab off the back of a house has to pitch away from the foundation, and the seam between old and new cannot sit in a low spot. We check how water currently crosses the area at the estimate, because fixing drainage after the concrete is down means breaking it back out.
