Blister

A durable solution for DDA compliant crossing points. In modern multi-function urban landscapes, crossing points are frequently driven over or parked on either accidentally or otherwise. These cleverly designed units are capable of withstanding accidental overrun from the heaviest loads on the road, while still providing the necessary physical and visual indicators of a pending hazard. The blisters have been positioned in such a way that the blocks can be laid in any pattern while still maintaining the correct formation to satisfy BS EN 1339.
