Sprung Sports Wood Flooring
Technical · Sprung floors
A sprung sports floor puts a resilient layer between the slab and the playing surface, so the floor gives slightly under impact instead of pushing back like concrete. Every LDK system is a sprung floor: resilient pads or a rubber mat, joists and load-bearing layers under a hardwood surface – in two permanent and two dismountable versions. The resilient layer, pads, joists, and load-bearing layers belong to one assembly, as outlined in sports floor shock absorbing padssports floor shock absorbing pads.

What is a sprung floor?
How a Sprung Sports Wood Floor Works
The “spring” in a sports floor does not come from metal springs. It comes from resilient pads under a timber structure: the pads compress under load and recover, while the joists and load-bearing layers spread the load across the floor.
- Resilient layer – 12 mm pads (W01, W02), 20 mm pads (W05) or an elastic rubber mat (W03).
- Joists – LVL joists, a double pine grid or keelson plates carry the floor above the pads.
- Load-bearing layer – plywood, composite board or a rough board / load panel spreads the load.
- Hardwood surface – 22 mm maple or birch (W01, W02, W05) or high-grade maple panels (W03).

Choosing a sprung floor
Permanent or Dismountable Sprung Floor?
Permanent sprung floors
W01 and W02 are fixed in place for school gyms, university halls, sports centres and training venues.
View permanent systems →Dismountable sprung floors
W05 and W03 are built to FIBA standards and assembled from panels for competitions, events and rental.

FAQ
Sprung Sports Floor FAQ
What is a sprung sports floor?
A floor with a resilient layer – pads or a rubber mat – between the slab and the timber structure, so the surface gives slightly under impact and recovers.
Are all LDK floors sprung floors?
Yes. All four LDK systems have a resilient layer: 12 mm pads in W01 and W02, 20 mm pads in W05 and an elastic rubber mat in W03.
How thick is a sprung sports wood floor?
LDK systems are 70 mm (W01), 114 mm (W02), 84 mm (W05) and 88 mm (W03) in total.
Can a sprung floor be laid on concrete?
Yes, on a flat, dry slab: within 5 mm under a 2 m straightedge, C25 concrete or stronger and moisture below 14%.
