CONCRETE SLABS
A practical surface begins below the finish.
Define what the slab will do
A slab’s intended use drives the conversation about preparation, concrete and finish. Share the approximate dimensions, planned loads and whether the area will be enclosed, exposed to weather or covered by another surface. If a future structure or heavy equipment is planned, that needs to be part of the project information from the start.
Prepare the ground and set the elevations
A stable supporting surface and appropriate elevations are important before concrete arrives. The preparation scope depends on existing materials, ground conditions and the work specified for the project. Outdoor slabs also need a considered drainage plan. An area can appear flat while still directing water toward a doorway or creating an unwanted low spot.
Forms, reinforcement and embedded details
Forms define the slab’s limits and elevations. Reinforcement, thickened areas, openings, embedded items or other details must reflect the project requirements where applicable. If another trade needs to install work beneath or through the slab, coordination should happen before placement. Late changes can affect both the concrete scope and the schedule.
Concrete placement and the selected finish
Placement, leveling, finishing, jointing and curing are coordinated stages. A surface that will remain outdoors can need a different texture from a surface intended to receive another finish. We discuss those needs before estimating the work so the concrete scope supports the intended use without assuming every slab requires the same finish.
Replacement and existing slab conditions
Cracking, settlement, surface deterioration and drainage concerns should be evaluated before choosing between repair, resurfacing and replacement. A new surface treatment does not increase the slab’s structural capacity or stabilize the ground underneath it. Where existing concrete cannot support a suitable repair, removal and new work may be the appropriate scope.
Protect the slab after placement
Keep people, equipment and stored materials off the slab until it is ready for the intended use. Follow the curing and loading guidance for the work, and coordinate later trades to avoid damage. For ongoing care, use cleaning methods compatible with the finish and pay attention to new movement, water accumulation or changes in the slab’s use.
A clear path to your estimate
- Share the use and approximate dimensions.
- Review plans, site conditions and access.
- Confirm the concrete scope and finish.
