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

Prestressing steel wire is used for prestressing concrete structures. Prestressing steel wire is made of wire rod which is either manufactured by cold-forming and subjected to a finishing thermo-mecha

Reinforcing steel in coils is hot-rolled and cold-drawn reinforcing steel in coil form. It is manufactured in coils or wound on reels at the manufacturing plant and then straightened, bent and cut or

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

Membranes for use as roof or wall underlay are installed underneath the roofing of pitched roofs or underneath the external wall cladding. They serve as an additional rainproofing measure to prevent t

Flexible sheets for concrete waterproofing are used as an additional waterproofing measure for waterproof concrete systems. For this, the flexible sheet is inserted into the formwork prior to concreti

Joint sealing tape is used to seal joints between windows and facades or facade joints for protection against wind and driving rain. It is usually compressible to compensate for temperature-induced fa

Punching shear reinforcements are special reinforcements used in place of stirrups or bent reinforcements to increase the punching shear resistance of beam supports for reinforced concrete floor slabs

Liquid applied roof waterproofing kits are usually multi-component systems and are applied in liquid form in multiple layers. After curing, they form the roof waterproofing. Waterproofing of buildings

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

Drainage systems serve to drain rainwater or surface water from buildings in a defined manner. They are used below roof vegetation or are installed below ground around structures. There are linear and

Bridge deck waterproofing protects the bridge structure and/or any components or structures underneath it from water ingress. Bridge deck waterproofing usually consists of multiple layers, such as a p

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

Scaffolds are temporarily connected to the structure with scaffold anchors. A scaffold anchor consists of a part permanently embedded in the concrete (e.g. threaded plate or anchor plate), the connect

Headed bolts are made of round steel or reinforcing steel bars. The bars are headed at one end. A thread is rolled on or cut at the other end of the bar. The end can also be prepared for welding on of

An anchor channel is a fastening system that consists of a channel profile with permanently attached anchors and channel bolts. The channel profile with the anchors is fastened to the formwork prior t

A power-actuated fastener is a bolt made of steel with a bolt head or threaded connection also made of steel. It is driven into the concrete with the help of a power-actuated fastening tool with or wi

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

DIBt grants general construction technique permits (aBG) for floor and wall construction techniques which significantly deviate from the Technical Building Rules or for which no generally recognised t

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

Gabions are wire mesh boxes filled with graded aggregate. Individual gabions are assembled via stacking and connecting to form gabion assemblies. These assemblies serve, for example, to stabilise esca

A plastic fastener consists of a plastic sleeve and a steel or plastic expansion element. The plastic fastener is placed into a pre-drilled hole in the base material and anchored through expansion of

Metal fasteners are post-installed mechanical fasteners for use in concrete. They are placed in pre-drilled holes and anchored in concrete through friction and/or an interference fit (mechanical inter

A fire-resistant partition with opaque and/or glazed panels is a non-load-bearing internal wall, usually consisting of a subframe (mullion and transom) clad on both sides (usually with mineral boards

Fire-resistant mobile partitions are multi-part systems, consisting of mobile elements and connections to the adjoining components, which meet the requirements for fire-resistant, non-load-bearing, se
