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

Special fire-resistant components in ventilation technology are service duct components consisting mainly of a supporting tray, cladding, supply and discharge lines, electrical cables and ventilation

Fire protection systems mainly consist of straight air duct sections, fittings, seals, connectors and fasteners, classified or unclassified wraps and shut-off devices for fire and smoke etc. They may

Fire dampers are installed in air ducts of ventilation systems in the area of fire-resistant separating elements to prevent the spread of fire and smoke along the ductwork to other fire compartments f

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

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

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 – 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

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 (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

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

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

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

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

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 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 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 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 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 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, or ETICS for short, especially include adhesive foams for insulation products, reinforcing textiles and fixings f

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

External thermal insulation composite systems, or ETICS for short, are multi-layer systems used to insulate the external wall of a building. ETICS generally consist of insulation boards bonded to the
