Blister Block  provides a practical and highly effective solution for inclusive pedestrian environments, combining safety, accessibility, and durability. Designed to act as a warning surface for visually impaired users, the distinctive blister profile consists of rows of flat-top domes that can be detected underfoot and by cane, helping pedestrians identify crossing points where there is no kerb upstand.

The simple yet recognisable design makes Blister Block an essential element in modern public realm projects, including controlled and uncontrolled pedestrian crossings, footpaths, streetscapes, and urban regeneration schemes. Available in both Buff and Red, it can be integrated seamlessly into a wide range of landscape and infrastructure designs.

Safety & Accessibility

The universally recognised blister pattern provides a clear tactile warning surface, helping to improve accessibility and pedestrian safety. Widely used across public infrastructure projects, it assists visually impaired pedestrians in navigating crossing points with confidence.

Durability

Manufactured using hydraulically pressed semi-dry concrete, Blister Block delivers excellent strength and long-term performance. The hard-wearing surface is designed to withstand pedestrian traffic and, when installed in accordance with the relevant standards and sub-base requirements, is suitable for vehicular applications as well.
