Sewer rehabilitation measures are only complete after the shafts have been rehabilitated. These include, for example, control shafts, pumping stations, rain basins, etc.
Braumann creates free travel for clearing vehicles
We offer our clients a reliable and cost-effective solution to raise or lower manhole covers exactly to the road level.
When replacing manhole covers, the existing manhole cover including the frame is removed and the new manhole frame and manhole cover is offset. The circular asphalt area, which has been removed, is then restored with mixed material.
Thanks to the easy handling of the SP V300 shaft frame cutting machine, nothing stands in the way of a quick replacement.
Braumann uses the injection method for sealing.
We insert holes in a defined grid into the shaft wall and screw in the drill packers. With injection pumps the resin is then injected behind the shaft wall via the packers to seal the shaft on the outer wall against intruding water.
Braumann uses a highly efficient rehabilitation process
The shaft rehabilitation process used by Braumann with a "KS-ASS System" is based on more than 15 years of experience.
A compact, mobile system
The operation is conducted via the touchscreen of the on-board computer. It also calculates important parameters such as the layer thickness, the residual mortar quantity and the time required – on the spot. The entire process equipment is mounted in an upgraded, construction site-ready VW Crafter. A really compact system with automatic shaft data acquisition for the renewal of your shafts!
Braumann skilfully handles everything up to the last detail
During the rehabilitation, defective shaft gutters are removed, new Duroton sole shells are placed in a mortar bed. The sole shells are then poured with mortar and the surface is smoothed out.
In the case of heavily stressed shaft structures, a lateral lift of approx. 10 cm with GRP hand laminate can still be produced after the berm. Glass fibre mats are soaked in silicate resin and applied in 3 layers. The second layer is plugged to the existing shaft wall.
