Temporary structures are repeatedly erected and taken down. They include, for example, bleachers, tents and rides for fairgrounds. Temporary structures are special structures within the meaning of Sec

Prestressing steel strands are used for prestressing structures. A prestressing steel strand is made from a number of wires twisted together in the same direction and with the same lay length. The str

With point supported glazing, the glass pane is mechanically fixed to the substructure either via point fasteners installed in drilled holes or via clamps (edge clamps). Point supported glazing is use

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

Waterproofing slurries are used for waterproofing of buildings. Differentiation is made between mineral-based waterproofing slurries (rigid or flexible) and polymer-modified thick coatings. In additio

Systems for limiting hydrocarbons in mineral oil containing wastewater with biodiesel, bio heating oil and ethanol contents are systems for treating wastewater containing up to 100% biodiesel and bio

Systems for treating stormwater run-off containing mineral oil serve to purify run-off from motor vehicle traffic areas to such an extent that the effluent may subsequently be infiltrated into the gro

Translucent roof or wall systems are composed of single- or multi-layer flat or curved plastic sheets generally supported by aluminium support profiles and their fasteners. They are used both for roof

Single-room ventilation units ensure a controlled air exchange between the building interior and the outside environment which is independent of the ventilation behaviour of the occupants. Ventilation

For these facade systems, the external wall cladding is fixed mechanically to the subframe, e.g. with the help of screws, rivets or clip fasteners. The facade systems can be executed as ventilated or

A bonded fastener consists of a fastening element and a bonding material (mortar). Bonded fasteners are available as injection systems or cartridge systems. They are placed into pre-drilled holes and

Curtain injections are used for retrofit waterproofing of damp structures, e.g. basements. For this, a gel is introduced into the surrounding soil (or groundwater), where it hardens. Waterproofing of

Soil injection products are products used for injection into the subsoil as a pore injection for sealing soil for geotechnical purposes (e.g. construction pit sealing). Earth work and foundation engin

Supply ventilation units serve to supply indoor spaces with filtered and possibly preheated outside air. Exhaust ventilation units serve to remove exhaust air from indoor spaces. Ventilation

Tension rod systems and cable tension members are used, for example, for trusses, suspensions, cross bracing and wind bracing, particularly in engineering works (new structures) but also in the repair

Polymer-modified bitumen thick coatings are used for waterproofing elements in contact with soil. Waterproofing of buildings

Coatings for resilient floor coverings can consist of several layers and/or products and be one-, two- or multi-component systems. Polyacrylates, polyurethanes, epoxy and alkyd resins and others are u

Wood floor coatings can consist of several layers and/or products and be one-, two- or multi-component systems. Polyacrylates, polyurethanes, epoxides, alkyd resins, curing oils, waxes and others are

With wood flooring, the floor covering is made of wood. Various designs are possible for parquets . In general, wood elements are arranged in specific patterns. Variants range from solid parquets to m

Floor coatings are applied to load-bearing substrates. Such coatings – for example, based on synthetic resin – can be used immediately after curing. They can be made up of multiple layers and differen

In timber construction, a large variety of glued timber and wood-based products are used for a wide range of uses. These include: glued laminated timber, glued solid timber, plywood, laminated veneer

Special forms of reinforcing steel comprise prefabricated elements consisting of reinforcing steel and steel that are used as reinforcement for concrete members, e.g. fabric made of rebar in one direc

Galvanised or stainless steels can be used to improve the corrosion resistance of steel used for the reinforcement of concrete members. The advantage of using reinforcing steel with improved corrosion

Welded fabric and steel wire mesh products are prefabricated reinforcements consisting of longitudinal and transverse wires welded together. They are used to reinforce slab-shaped concrete members. We
