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

the soil with a binder suspension on site. With the help of suitable tools, a defined volume of soil is mixed with a predetermined volume of binder suspension in a wet mixing process to form a homogeneous

Thermoplastic moulding compounds are used in a variety of ways to manufacture semi-finished products and construction products. They are used, for example, in the manufacture of bulk silos, cesspits and

devices made of plastic are especially suitable for liquids hazardous to water because they often have a more favourable corrosion behaviour than those made of metal and hence are resistant to various storage

The fastener is inserted into a pre-drilled hole and tightened with a setting [...] systems consist of connecting channels and grouting mortar. The connecting channel consists of a casing made of a corrugated galvanised sheet metal in which flexible high-strength wire rope loops are arranged [...] post-installed connection of existing concrete with a concrete overlay. They consist of headed steel parts. The steel part is anchored in the existing concrete as a bonded or metal fastener. The connector is anchored

Joint seals are mainly used for elements made of waterproof concrete in accordance with the DAfStb guideline on waterproof concrete structures to seal the joint against soil moisture as well as pressu

Construction techniques and construction products (usually XPS, EPS or foam glass boards) for perimeter insulation of walls and basement floors in contact with the ground must meet special requirement

in a form-fitting manner. When the composite member is loaded (usually in bending), longitudinal shear forces are transmitted via the shear connectors, which thereby enable the member to act as a single

A prefabricated stair system consists, e.g., of steps, landings, stringers, handrails, balustrades and fasteners. The following stair systems are distinguished: stairs supported by load-bearing bolts,

A sandwich panel consists of two faces and a supporting core. The supporting core is made of a thermally insulating material. It is connected to the two faces via an interference fit such that the three [...] components act together structurally. Sandwich panels are used as wall or roof elements and are fastened to a subframe through visible or concealed fasteners. Roofs, walls, facades

Facade systems with bonded facade cladding are ventilated external wall claddings where the cladding panels are bonded to the subframe profiles using an interference fit. The subframe is made of metal

In timber construction, screws are used to permanently connect timber elements to other elements or to reinforce timber elements. In this work area, you will also find threaded rods and screws for ext

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

Usually a glass structure which provides fall protection contains a laminated safety glass which has a favrouable fracture behaviour due to the interlayer used [...] Barrier glazing is glazing designed to prevent people from falling to a lower level. In the event of impact on the glazing, the risk of injury is supposed to be low. Furthermore, the lower-lying traffic

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
