This tactile blister slab is a precast concrete paving unit measuring 400 x 400 x 50mm, produced in red for high visual contrast. The prominent pimpled surface is designed to offer grip and can be detected underfoot, providing orientation and warning for pedestrians.
Widely used at the top and bottom of pedestrian crossings and drop kerbs, this slab helps indicate safe crossing points. It is commonly installed as part of public realm and highway improvement projects to assist people with impaired vision while navigating urban environments.
