How much matting is actually needed
The usual matting installation is far shorter than the job requires. A person carrying mud on boots needs several full paces on an absorbent surface before the transfer is substantially complete, and a single mat inside a door provides one. Vehicles and trolleys need a corresponding scraper section outside. Undersized matting gives the appearance of a control without the effect.
Sizing it properly means measuring the approach rather than fitting the space available. Where the entry cannot accommodate the length required, the alternative is a scraper zone outside plus a longer internal run, or accepting a higher internal cleaning frequency as a deliberate trade-off. Stating that trade-off in the proposal lets the client decide with the numbers visible. Where a mat rental service is in place, the exchange frequency should be checked against the actual soiling rather than left on a standard contract cycle.
