Pool Pre-Handover Testing

The pool handover compliance gap

Most pool flooring specifications include slip resistance — typically PTV 36+ wet or higher — but verification at handover is frequently absent. A manufacturer datasheet showing the product's specification is not in-situ verification of the actual installed surface. If a slip incident occurs in the pool's first years of operation and the surface is found to be below specification, the absence of independent handover testing leaves both contractor and operator exposed.

What we deliver at pool handover

• Pendulum testing across all wet barefoot zones (pool surround, steps, ramps, hydrotherapy approach) using Slider 55
• Pendulum testing across shod and sock zones (changing rooms, lobby transitions) using Slider 96 and Slider 57
• Surface roughness Rz across the same test points
• Identification of any zones falling below specified PTV thresholds
• Recommendations for remedial treatment where required
• Re-testing after remedial works to evidence final compliance
• UKAS-accredited report for the project handover file (O&M manual, building file, operator's safety file)

Programme integration

Pool pre-handover testing is typically scheduled in the final two weeks before practical completion, after final commissioning of plant and pool fill, and before snagging closes. The pool needs to be in normal operating chemistry (not the high-chlorine commissioning state) for the surfaces to be in their service condition.

Where the project includes phased opening (e.g. hydrotherapy commissioning before main pool, or staff training pre-public opening), we can attend at each phase to test what is ready, providing the contractor with progressive verification rather than a single end-of-project bottleneck.

Common pool handover findings

• Polished or epoxy-coated pool surround tiles that meet visual specification but PTV-fail wet
• Pool step nosings or treads that have been replaced with smoother material than originally specified
• Hydrotherapy ramps with insufficient slip resistance for the gradient
• Shower cubicle floors specified to a slip-resistance threshold but installed in a polished finish that fails wet pendulum testing
• Tile-and-grout zones where the grout has cured proud, creating uneven wear and localised slip risk
• Drain-grate covers significantly smoother than the surrounding tile

Remedial pathway and re-testing

Where testing identifies a non-compliant zone, the typical remedial pathway is: chemical anti-slip treatment for polished porcelain or natural stone; mechanical re-finishing for resin and concrete; replacement for tile zones where treatment is not viable. We re-test after remedial works under the same UKAS methodology so the handover file shows both the original test result and the verified remediation. This is the documentary chain insurers and operator solicitors look for in any subsequent claim.
