Watco in Surrey specialises in flooring materials for all types of indoor and outdoor functions. Its ribbed tactile plates are coated with aluminium oxide for slip resistance and high wear resistance. They are 4mm thick and can be fixed to your paving using Watco's adhesive mastic and then screwed for extra security.
The plates cost £30.50 each or £105.20 for a pack of four. A 310ml tube of mastic, sufficient for fixing eight plates, costs £3.80.
