What should you know about our Customized Constructions?


General info

De Bonte Group offers prefabricated custom-built constructions with the BENOR label including special manholes, in and outlet constructions, overflows, pump puts, end walls, etc. This is how we are able to manufacture constructions of up to 60 tonnes for you. If your site does not allow for such tonnage, we offer a modular construction package consisting of smaller elements that can be connected on site without the need for reinforcement with sand/rubble. The small, modular elements eliminate the need for telescopic cranes. You will find more information here.
