“Concrete and Polypropylene make an ideal combination” PREDL®
Combining both materials together perfects the whole process of connecting the manhole chamber to the pipeline.
The polypropylene unit provides prefabricated channels and connectors which:
- ensure long lasting waste water-resistant protection for concrete manholes
- is economically advantageous
- allows any orientation to be manufactured and delivered quickly
- absolute watertightness
- connections available to varying types of pipe
Benefits of using the Easi-Base
- Provides immediate watertight structure, allowing quicker follow-up with subsequent construction activities
- Provides the missing link in a complete precast solution to manhole construction
- Caters for pre-fabrication to accommodate all combinations and variations in entry / exit pipes
- Improves safety of construction (slips / trips and other hazards), as pre-formed base and channels reduce the number of site operations thus avoiding the need for personnel to repeatedly climb in and out of manhole during construction
- Provides a solution that offers increased confidence in ability to meet industry standards
- Yields environmental advantages - less concrete used and less excavated material removed from site
- Offers cost benefits with reductions in construction time and resource requirements
- Eliminates material wastage associated with current practice in manhole base construction
- Reduced skills requirements, due to degree of pre-fabrication
- Eliminates requirement for in-situ internal benching, as it is incorporated in the liner
- Clean access for inspection. Reduces maintenance and running costs.
