Garage Floors & Slabs
We build the base right, set the vapor barrier where it belongs, and pour your slab level so it carries the load and stays flat through Pennsylvania winters. Garage floors, shed and pole barn slabs, and equipment pads across the Lehigh Valley.
Slabs & Garage Floors
A garage floor or a shed slab does not fail because of the concrete on top. It fails because of what is under it. A soft or skipped stone base lets the slab settle, hold water, and break apart.
Murray General Contracting pours concrete slabs and garage floors across the Lehigh Valley, from Allentown and Bethlehem to Easton and out to Breinigsville. We dig to a firm subgrade, compact a stone base, lay a vapor barrier under any heated or interior slab, and pour at the right thickness so the floor carries vehicles, equipment, or storage without cracking up.

How We Pour A Slab
We strip the topsoil and dig down to firm, undisturbed ground so the slab sits on a base that will not give way under load.
We lay and compact a stone base in lifts, then roll out a poly vapor barrier under any heated or interior slab to keep ground moisture out of the floor.
Squared forms set the edges and a slight pitch toward the door. We add wire mesh or a rebar grid where the slab will carry heavier loads.
One continuous pour, screeded dead flat and floated to the finish you need, smooth for a garage or broomed for grip where the slab sees rain.
We cut control joints so the slab cracks along planned lines, not at random, then walk the finished floor with you before we leave.
Why It Lasts
The stone base is where a slab lives or dies. We compact it in lifts so the floor has nothing to settle into once it carries weight.
Under a heated or interior slab we lay poly so ground moisture stays out of the floor and away from anything you store on it.
Wire mesh or a rebar grid ties the slab together so a truck, tractor, or equipment can sit on it without breaking the concrete.
We screed the slab level and cut control joints so it stays flat for jacks, shelving, and tires instead of mapping with cracks.
Slab Work We Do
Need the structure under and around a slab too? See our footers and foundations. If the crew is already on site, it is a good time to pair the work with a new driveway or patio poured by the same hands.

Slab Questions
Four inches is the standard for a garage floor or shed slab that carries cars and storage. We pour five to six inches, with rebar, where heavier loads sit, like a work truck, a tractor, or a pole barn that holds equipment. We size the slab to what you actually park on it.
You need one under any slab that will be heated, finished, or used as living or work space, because ground moisture will wick up through bare concrete and damage floors, tools, and stored goods. We lay a poly vapor barrier over the stone base before we pour those slabs. An open shed or a detached pad usually does not need one, and we tell you which case yours is.
Most slab cracks come from a weak base, no control joints, or a slab poured too thin. Concrete also shrinks as it cures and the ground moves through Pennsylvania freeze-thaw. We compact a real stone base, pour the right thickness, and cut control joints so any movement follows planned lines instead of breaking the floor apart.
Yes. We pour shed slabs, pole barn slabs, equipment pads, dumpster pads, and pads for air conditioners and generators across the Lehigh Valley. Tell us the footprint and what will sit on it, and we build the base and reinforce the slab to suit.
Yes. We pour slab additions and extensions tied into what you already have, matching the thickness and setting an isolation joint so the new section can move on its own. We will look at the existing slab first and tell you honestly whether tying in or pouring fresh is the better call.
