Arrow’s Precast Concrete Headwalls Provide an ideal end connection point to outfall pipes into open watercourses such as rivers, culverts, collection and balancing pools.
They are a very efficient alternative to intrusive shuttering of soil embankments and costly on-site formwork with ready-mixed concrete, making them particularly suitable for use in hard to reach locations and in environmentally sensitive areas.
Where time constraints exist such as in tidal flow situations, concrete headwalls can be quickly positioned, secured and backfilled, providing immediate stability around the point of water discharge.
Headwalls are designed and manufactured to BS EN 13369 & EC2 standards
