ROTOMOLDING INTERHOL MANHOLES

ROTOMOLDING INTERHOLE MANHOLES

Enlargement of production is made on a filed of the manhole, as integral part of sewage infrastructure projects.
This development is in a point of assortment and technology.
They are producing from polyethylene, with outside black color and inside white layer, for better inspection and maintenance.
These product are produced by rotomolding technology. The different weakness which are appeared at traditional manholes, like damaged covers, corroded stares, leakage and mixing of underground water are eliminated with this type of manholes.

ROTOMOLDING technology enable monolithic production of INTERHOLE manholes and assembling parts which are completely integrated and make a integral INTERHOLE MANHOLE, which warrantee complete safety of the system. Totally made of same material, with conic made top cover enable very easy installation on the project with precise assembling of concrete plate, as finishing step of their installation. They are multi dimensioning in a view of branch connection but the base is with dimension of 1000 mm inside diameter.

They are producing according EN 13598-2 and completely satisfy the standard for installation EN 1610.
