- Reduced footprint, with 1200mm sealed manhole shaft access
- Reduction in the time taken to build manholes, from may days to just hours
- Greatly reduced Health and Safety risks on site
- Removes the need for any benching on site or concrete back-fill
- Economic method for access to tank system eliminating the requirement for a traditional manhole, with for man or non-man access
- Long term easy access into the system for maintenance
- Watertight joints to both pipes and manholes, including load bearing seals
- Established and proven product range that is a quality assured and kitemarked
- Inherent structural strength of concrete with an 120 year design life
- Systems can be designed to suit most structural and hydraulic specification including installation under roads
- Flow control devices can be incorporated into the system, such as Hydro-Brakes®, Orifice Plates, Penstocks or a combination of all of them.
