What slab Work covers
Slab work covers laying and repairing concrete floors. Performance is decided beneath the surface: a properly compacted base, a damp proof membrane where the slab is on ground, and control joints that decide where cracking happens.

Ground floor and structural slabs, where the base, the damp proofing and the joints decide performance.
Waystar carries out this work on residential and commercial property in Brooklyn and across New York City. Every project starts with a look at the building, and the scope, the materials and the figures are written down before anything begins.
When might you need it?
These are the signs owners usually notice first.
- A slab that has cracked or settled unevenly
- Damp coming up through a ground floor
- A floor that is out of level across the room
- Surface dusting or breaking up under traffic
- A new floor needed for a garage, basement or extension
What the work involves
- Assessment of use, loading and ground conditions
- Existing slab broken out and removed where required
- Sub base placed and compacted in layers
- Damp proof membrane laid and lapped where on ground
- Reinforcement placed to the specified cover
- Concrete poured, levelled, finished, jointed and cured
How the process works
Establish the loading
What the floor carries decides thickness, reinforcement and base preparation.
Prepare the base
Sub base compacted in layers, then the damp proof membrane laid and lapped.
Place and finish
Reinforcement set to cover, concrete poured, levelled and finished.
Joint and cure
Control joints cut at the right time and the slab protected while it cures.
What you get
- A base that carries the load without settling
- Damp proofing that is continuous rather than punctured
- Joints placed so cracking is controlled instead of random
What affects the scope
- Slab area, thickness and loading requirements
- Ground conditions and how much preparation is needed
- Whether a damp proof membrane or insulation is required
- Access for concrete delivery and placement
This is a preliminary planning range, not a quote. A property visit is required before any price is confirmed.
Frequently asked questions
Why is my floor damp?
On a slab laid on ground, usually a missing, punctured or badly lapped damp proof membrane. It cannot be fixed reliably from above.
Can a slab be levelled without replacing it?
Sometimes, with a levelling compound over a sound slab. If the slab has settled or cracked structurally, that only hides it.
When can the floor be used?
Concrete gains strength over time and finishes have their own drying requirements. The scope sets out the waiting periods.
