Surface protection systems
The term surface protection system covers a range of different types and designs. Besides polymer-containing coatings for concrete structures, organosilicon compounds can also be used as water repelle -
Metal sealings for collecting devices
Metal sealings are installed in collecting devices made of concrete to make them liquid-tight. Liquid-tight collecting trays and devices are enclosures serving to meet the requirement for secondary co -
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 -
Bulk silos made of plastics
Bulk silos made of plastics – glass fibre-reinforced polyester resin (UP-GF) or polyethylene (PE) – are vertical cylindrical containers with funnel-shaped bottom outlets. They are used, e.g., for stor -
Textile strengthening materials for manufacturing pipes, tanks and collecting devices made of plastic (GFRP)
Together with reaction resins, textile strengthening materials (glass fibres in the form of woven fabrics, rovings or meshes) are used to manufacture plastic laminates (GFRP). These laminates are used -
Reaction resins for manufacturing pipes, tanks and collecting devices made of plastic (GFRP)
Reaction resins (vinyl ester resin, epoxy resin, polyester resin) in their cured condition are thermosets and are used in construction products in a large variety of ways. Laminates made of these resi -
Tanks and collecting devices made of glass-fibre reinforced plastic (GFRP)
Tanks and collecting devices made of plastic are especially suitable for liquids hazardous to water because they often have a more favourable corrosion behaviour than metal tanks and hence are resista -
Metal pipes and their fittings, seals and valves
Metal pipes and the associated fittings, seals and valves used in the conveyance of liquids hazardous to water must meet certain tightness and media resistance requirements set out in water legislatio -
Collecting trays and devices made of metal
Liquid-tight collecting trays and devices are enclosures serving to meet the requirement for secondary containment under water law. They are used to collect and retain substances hazardous to water le -
Double-skin metal tanks for liquids hazardous to water
A double-skin tank is a tank in which there is a second skin at least up to the height of the maximum permitted filling level and the interstitial space between the inner and outer skin is suitable as -
Single-skin metal tanks for the above-ground storage of liquids hazardous to water
Single-skin tanks made of metal (mainly steel) for the above-ground stationary storage of liquids hazardous to water are available in various volumes and shapes. Common variants include: vertical cyli -
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 -
Injection products and systems
Injection products and systems are used for repairing concrete structures. A distinction is made between different repair objectives. The filling objective 'Closing (crack width control by filling)' i -
Strengthening of concrete structures with bonded reinforcement
The work area 'Strengthening of concrete structures with bonded reinforcement' comprises kits for retrofitting aimed at increasing the flexural and shear resistance of existing concrete structures (st -

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 mixing techniques
Soil mixing techniques serve to create unreinforced structural elements (single elements or bodies of soil made of single elements) through grouting of the soil with a binder suspension on site. With -
Driven piles made of ductile cast iron tubes
Driven piles made of ductile cast iron pipes are displacement piles and are used when soil strata have no or little load-bearing capacity. The piles transfer the loads to lower strata with higher load -
Vibro stone columns
Vibro stone columns are unreinforced pile-like structural elements. They belong to the group of displacement piles and can be used as load-bearing or foundation elements for transferring loads from st -
Micropiles
Micropiles serve to transfer axial tensile and/or compressive forces into the ground. They are used, among other things, as foundation elements. Micropiles are driven into the ground using drilling or -
Soil nailing
Soil nailing is a measure used to increase the tensile and shear strength of the soil to such an extent that the nailed soil can be considered as a monolithic block for verification purposes. Soil nai -
Ground anchors
Ground anchors are prestressed anchor systems for transmitting tensile forces into the load-bearing ground, e.g. for anchoring shoring systems or slope stabilisation. Ground anchors consist of tendons -
Auxiliary materials and accessories for external thermal insulation composite systems
Auxiliary materials and accessories for external thermal insulation composite systems, or ETICS for short, especially include adhesive foams for insulation products, reinforcing textiles and fixings f -
Composite insulation elements
Composite insulation elements are prefabricated insulation elements which are mechanically fixed directly to the load-bearing wall as external wall cladding. A composite insulation element consists of
