Sports flooring

Ball bounce, shoe grip, shock absorption and line markings all come from the build-up — and the same hall usually has to host assemblies and exams too.

A sports floor is a system, not a sheet. The surface layer provides grip and markings, the backing provides shock absorption and energy return, and the installation provides flatness and dimensional stability. Change any one of them and the ball behaves differently. This is why sports flooring is specified by performance standards — ball rebound, vertical deformation, shock absorption, friction — rather than by thickness alone, and why a 6 mm sheet on a bad screed performs worse than a 4.5 mm sheet on a good one.

Point-elastic and area-elastic constructions answer different sports. Vinyl with a foamed backing is point-elastic: cheap, fast to install, good for fitness areas, multi-use halls and school gyms, and fine for badminton and volleyball. Area-elastic systems on a resilient batten or foam layer are what competitive basketball and handball want, because they absorb impact across a wider area and return energy to the player. Where the hall is also used for exams and assemblies, the floor has to tolerate temporary staging and chairs without permanent indentation.

Line markings and colour are where sports floors are most often wasted. Painted lines wear off in a season and leave ghosting when the court layout changes; inlaid or welded-in markings in a contrasting colour last as long as the floor and can be reconfigured when the hall is re-zoned. A common practical choice is one base colour for the whole hall with inlaid lines for two or three court layouts, so the space can switch from badminton to basketball to a parents' meeting without anyone repainting anything.

Typical areas: sports halls, courts, fitness rooms, dance and multi-use rooms, changing areas
Usual specification: 4.5–6.5 mm vinyl with foamed backing (point-elastic), or area-elastic system for competition
Performance data to request: ball rebound, vertical deformation, shock absorption, friction — per the standard in force
Markings: inlaid or welded-in lines, not paint, so layouts can change without ghosting
Subfloor: flatness and moisture first — a sports floor cannot compensate for a moving slab
