DN1500 & DN1800 Precast Concrete Easi-Base
The Easi-Base range extends to include diameter DN 1500 and DN 1800 concrete manhole bases. These Bases will accommodate Concrete, Clay, Twin Wall and uPVC Pipes from DN 300 to DN 900mm. Connection to the base will be made on site by applying epoxy resin to a conventional socket / spigot butt before insertion into the opening of the precast manhole.
Bases are traditionally constructed manually in-situ using ready mix concrete which is troweled to form the base and benching. This practice is labour intensive and requires optimum site conditions to achieve a quality result. With the precast alternative many of the variable factors in the manual process are negated.
Benching and channels are generally pre-formed with concrete, but glass reinforced plastic (GRP) linings are available
for special applications on request. The DN 1500 and DN 1800 units are WRc approved and offer the same construction
benefits as the DN 1200 Easi-base.
The benefits of Concrete Easi-Bases are:
- Cost savings achieved as a result of speed of installation and reduced resource requirements
- A water tight homogenous base section is achieved once the base is lifted into position and when utilised with our new “no lifting holes” chamber rings, the complete structure is water tight.
- The Base Unit requires no further wet-trades once it is fixed into position
- Follow up operations can commence immediately
- Quality of the Channel and Benches are far superior because the unit is precast in a factory environment
- It provides a solution that offers increased confidence in ability to meet industry standards than current practice
- Reduced site skill requirement due to factory pre-fabrication
- Improved construction safety as ground workers spend less time in trenches and inside the manhole
- It yields environmental advantages as less concrete is used and less excavated material being disposed in landfill
- Maintenance of the channel and benches are reduced due to the quality of the factory produced product
- Should entry be required by maintenance personnel, the quality and disposition of the benches enhances the Health and Safety of maintenance crews
