Manholes
Polyethylene manholes have been successfully used for more than 40 years in all parts of the world and were first introduced in the Philippines by Krah Pipes Manila, Inc. They are distinctive because, unlike RCP and steel, we can quickly and easily produce our HDPE manholes using state-of-the-art German technology. The benefits are well-known, and the market is expanding.

Tailor-Made Design for specific project requirements
They can essentially be divided into two groups. For smaller dimensions, system shafts are used, whereas tangential shafts are used for considerably larger dimensions. They mainly differ in how they stand and where they are in relation to the pipe.
All manholes have a cylindrical shape by design. Because the reinforced concrete top plate rests directly on the vertical wall of the construction, it is made to withstand full highway traffic loads in the country.
Standard
Used when the manhole shaft is larger than the pipelines’ inlet and outlet.
