Our entire range of square/rectangular chambers is made using self-compacting concrete, which offers countless benefits:

• An attractive, sleek look, without the need for any post-treatment
• Perfect dimensions, due to curing in the mould
• Perfect watertightness
• The option of placing a rubber seal under the cover, instead of mortar
• Any fitted parts are cast in during the production process to guarantee watertightness
• Equipped with DEHA lifting clutches, in accordance with the safety regulations

Basic elements are cast monolithically (in one piece, the height of which differs per model). This offers the following benefits:

• Fewer parts to assemble = fewer steps during installation
• Fewer or no shaft rubber rings needed = save on the cost of rubber rings
• Fewer or no shaft elements = save on BENOR surcharges for shaft elements
• Reduced chance of leaks between the various elements
• More options for all your derelict and watertight solutions
