Precast concrete headwalls for drainage outfall connections into open water areas including collection ponds, swales and rivers.
- Low maintenance
- Cost effectiveness
- Quick fit installation
- Design specific solution
The strength and durability of precast concrete headwalls preserves the surrounding environment by minimising erosion at the outfall connection.
The quick positioning of precast concrete headwalls is a distinct advantage over ready mixed solutions with no on-site shuttering or formwork required. This proves ideal at difficult to reach areas and where time is limited.
Lifting loops attached to cast in lifting sockets provide a highly economic alternative to other lifting systems and enable easy manoeuvring with standard chains.
The aperture within the headwall will be sized and positioned to meet your requirements, so please contact us with your specific scheme details.
A range of accessories are available including flap valves, penstocks, safety grates (flat, hinged & cranked) and handrails. Ask us about relevant accessories to save time on site.
