| The fundamental principle behind the manufacture of Polycon manholes is to build a completely corrosion resistant and leak proof sewer. For abetter quality manhole construction, as muc h work as possible should be done at the manufacturing
Plant.Complicated manholes with varied pipe connections, floor configurati -on, channel bends and internal and external bottom drops are al availabl -e for our clients. |

| material and wall design. The bottom section of the manhole is manufactu red as a one piece unit for additional protection against leakage All types of pipes with the appropriate fittings for the respec -tive type of pipe canbe con-nected to the manhole. |  |

| Manholes of DN1000 mm can accept connections up to 500 mm,DN1200m m up to 800 mm, and DN 1500 mm up to 1000 mm. The bottom section of the manhole is simply drilled on site and the appropriate fittings are fixed in place. | ||||||||
| Where there are large connection diameters, Polycon™ manholes are man manufactured as pre-fabricated slabs which are assembled in the plant, re -ady for simple jointing on-site. The step and channel of the system manh -ole are manufactured to the precise size from seamless polymer concrete screed on pre-formed concrete base. The smooth contoured surface is par ticularly beneficial to the hydraulic flow. Climbing aids such as climbing iro -s, stirrups or ladders are fastened tothe manhole wall with stainless steel lock nuts. |
