Fast, Safe and Efficient Installation of FP McCann's Easi-Manhole Unit

A Precast Concrete Manhole System, built in under 1 hour!
FP McCann has gained instant recognition amongst ground works contractors and their specifiers for its fully integrated wide-wall manhole chamber unit. The precast concrete system incorporates the successful WRc approved DN1200 polypropylene lined Easi-Base with the recently launched 130mm wide-wall chamber ring available in four section depths (1000/750/500/250mm). The robust design provides a durable, water-tight installation with the requirement for a ready mix concrete surround eliminated.
Speed, ease of build and the resulting increase in site productivity, is a major benefit on offer from the Easi Manhole. From base to cover slab and backfill, a typical 3 metre completed unit can be in place and secure in under 90 minutes, thereby minimising the time operatives spend in the excavation. Traditional methods of base and chamber construction involving wet concrete and mortar trades can typically take up to 40 hours.
The reduction in time spent in the excavation has significant operative safety and welfare benefits and removing the need for concrete deliveries further enhances site safe practices. The benefits and advantages of using the Easi Manhole system are numerous. Key to its success is the following:-

• An extremely fast, efficient and economical method of constructing a manhole
• Significant Health and Safety benefits.
• An immediate secure watertight structure allowing for other trades to instantly follow on.
• Factory pre-fabrication of Easi-Base provides quality in channelling and benching and enables accurate combinations and variations for entry/exit pipes.
• 130mm Wide Wall chamber rings eliminate the need for concrete backfilling
• Maintenance of channels and benches aided by clean access for inspection
• Environmental benefits from re-using excavated materials
• A Guaranteed system.
FP McCann has also introduced the DN1500 wide wall manhole unit and the DN 1800 is in development.
