Reinforcing steel bars (rebars)
Reinforcing steel bars, or rebars for short, are reinforcing steel in the form of straight bars used to reinforce concrete members. The approval area only concerns rebars which deviate significantly f -
Swimming pools and water slides
This work area covers load-bearing plastic elements for swimming pools and water slides, in particular elements made of fibre-reinforced plastics. Plastics construction -
Free-standing chimneys
The category of 'free-standing chimneys' also includes chimneys that are restrained or supported laterally or mounted on top of another structure. Special constructions -
Polymer-modified bitumen thick coatings
Polymer-modified bitumen thick coatings are used for waterproofing elements in contact with soil. Waterproofing of buildings -
Jet grouting, high-pressure grouting
Jet our high-pressure grouting serves to produce structural elements (jet-grouted elements and/or jet-grouted bodies of soil made of jet-grouted elements) in the soil. These procedures are soil-streng -
Soil reinforcement systems
Reinforcement of soil serves to secure escarpments. The inserted geotextiles act via friction and interlocking with the surrounding soil. The stability, e.g. of embankment structures, is increased thr -
Cesspits made of thermoplastic materials
Cesspits are liquid-tight tanks, usually installed underground, for waste water containing faecal matter (sewage). Given that cesspits are not connected to the sewer system, professional emptying and -
Cesspits made of glass-fibre reinforced plastic (GFRP)
Cesspits are watertight tanks for domestic waste water containing faecal matter (sewage). Given that cesspits are not connected to the sewer system, professional emptying and disposal must be carried -
Limit switches
Limit switches are safety devices within the meaning of water legislation, installed in tank vehicles and acting together with overfill prevention devices to interrupt the filling operation before the -
Sealants for drains
Sealants for drains serve to prevent, in connection with pipework parts such as pipes and fittings, the leakage of discharged waste water. In the case of underground drains, the sealant also ensures t -
Inner linings for drains and manholes
Inner linings are prefabricated elements used for on-site lining of drains and manholes. They usually serve to improve corrosion protection. Inner linings must be fixed durably and tightly to the drai -
Ablation coatings
Ablation coatings are fire-stopping and fire-sealing products which are activated when exposed to high temperatures due to their chemical compositions. Chemical and/or physical reactions are triggered -
Non-metallic reinforcement
Glass fibre reinforced plastic (GFRP) rebars are one example of non-metallic rebars. They are serrated to ensure sufficient bonding with the concrete. Reinforcements made of glass fibre reinforced pla -
Other tendons
Other tendons include special prestressing components, e.g. for realising innovative construction techniques based using prestressing systems, also in combination with other manufacturing and reinforc -
