Control joints and saw cuts

Groove Cutting for Concrete Floors

Groove cutting (saw-cut control joints) is how a new concrete or VDF slab is divided so shrinkage cracks form on planned lines instead of randomly across the wearing surface. ASVDF Flooring cuts grooves on industrial and commercial floors as part of the pour sequence, then details joints where the specification calls for filling or sealing.

Why industrial slabs need groove cutting

Concrete shrinks as it dries. If joints are late, too far apart, or skipped, the slab cracks where forklifts and racking will feel it every day. Groove cutting is timed after finishing, while the concrete can still be cut cleanly, on a layout agreed with bay sizes, columns, and traffic aisles.

Where we cut

  • VDF and industrial concrete warehouse aisles
  • Plant and factory slabs at planned bay joints
  • Loading bays, parking decks, and large commercial floors
  • Joint widening or re-cutting where an existing floor needs repair detailing

Joints after the cut

A cut is only the first step. Depth, timing, and later filling or sealing decide whether the joint stays a working detail or becomes a spalled edge under wheels. We plan groove cutting with the same pour, not as an afterthought, and we will say when an existing cracked slab needs more than a new saw cut.

Frequently asked questions

After the slab is finished and has gained enough strength to cut without ravelling, usually within the first day or as the programme specifies. Cutting too late lets random shrinkage cracks form first.
