Safety by choice, not by chance
Slip testing across West Yorkshire
Independent, UKAS-accredited floor testing — grip measured wet and dry, by pendulum and surface roughness, with a report that proves a floor is safe.
The PTV scale — 36+ is low slip risk.
The pattern book
Slip testing, sample by sample
Eight swatches that cover what matters — the methods, the verdict, the duty and the proof.
The pendulum (PTV)
Grip measured wet and dry with a calibrated pendulum — a Pendulum Test Value for every area.
How it works →Surface roughness (Rz)
Microscopic texture measured in microns — vital where floors get wet or greasy.
The method →The verdict
A plain low / moderate / high result. 36+ PTV, or Rz above 20, is the low-risk band.
Your duty
Keep floors safe and assess the risk — the HSW Act and the Workplace Regulations.
Independent
No ties to any flooring or treatment company, and no commission. Nothing nudges the number.
Our laboratory
An environmentally controlled lab (ISO 291) testing 300+ flooring products a year.
