Complete inspection manhole with DN600 diameter is manufactured according to the desired height and connections. After the excavation pit in which it will be placed is prepared, if necessary, foundation concrete is made to improve the excavation base. It is also suitable to install prefabricated base concrete slabs for the base. Inspection shaft / manhole

It is lowered into the pit and placed in accordance with the project. Gradual side filling is done in accordance with the technique. After cutting the upper part when necessary according to the final cover elevation, if it is in the traffic area, a reinforced concrete collar to be placed under the ductile font or composite cover is placed on the compressed fill.

Filling is the most important procedure for the application to be performed safely. Filling construction is done according to ENV 1046.

Following the hydraulic or pneumatic leakage test, the chimney is ready for use.
