XR Range: 100‑Year Design Life Headwalls.
Engineered for extreme durability. Designed for long‑term performance.
The XR Range is an enhanced evolution of our established precast concrete headwall systems, developed for applications requiring an extended 100-year design life. Building on decades of precast expertise and the proven performance of our existing ranges, the XR Range represents a strengthened upgrade to conventional 50-year products. By increasing the wall thickness from 100 mm to 150 mm, it delivers improved structural strength, durability, and long-term resilience, ensuring greater performance over an extended lifespan.

Engineered for the Next Century: Thicker 150 mm wall construction
The XR Range has been structurally enhanced to deliver superior resistance to hydraulic forces, erosion, freeze‑thaw cycling and long‑term environmental exposure. This upgrade is particularly important for installations where access for future maintenance may be challenging or where infrastructure is expected to operate with minimal intervention. Built for high‑exposure applications, the XR Range is ideally suited for:
- Highway drainage and major infrastructure schemes
- Energy and industrial outfalls
- Large‑scale SuDS systems
- Remote or sensitive sites with long service life requirements
