What are Headwalls?
A headwall is typically an outlet from a sewer that allows flow from upstream pipework to discharge into an open watercourse, such as a river, pond, swale and culvert. Headwalls may also be used as inlets to surface water management systems receiving flow from a watercourse or open channel and conveying the flow downstream through an underground pipe.
Why Use Precast Concrete Headwalls?
- Precast concrete Headwalls adopt offsite manufacturing principles.
- They are safer to construct than in-situ build and can be placed into position quickly, significantly reducing construction time.
- The advantage of reduced construction time often translates into installed cost savings.
- Precast concrete Headwalls remove the need for digging out extensive areas of embankment. An in-situ build can require extensive infrastructure such as temporary formwork and shuttering. Precast concrete Headwalls are thus more environmentally sensitive.
- Precast concrete Headwalls can be supplied to fit pipes of varying materials and sizes.
- Precast concrete is strong and highly durable, providing asset owners with a reassuringly long service life and low whole life costs.
- Precast concrete is a low carbon, sustainable material made from local materials that can be recycled end of life.
