Glass fibre reinforced plastic (GFRP) rebars are one example of non-metallic rebars. They are serrated to ensure sufficient bonding with the concrete. Reinforcements made of glass fibre reinforced pla

Decorative wall coverings in roll or panel form are primarily applied to interior walls, partitions or ceilings for decorative purposes. They can be made of a variety of materials (e.g. vinyl, foamed

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

Resilient, textile and laminate floor coverings are covered by EN 14041:2004/AC:2006 and include, amongst others: Polyvinyl chloride (PVC) and rubber floor coverings: This type of floor covering usual

Other concrete construction techniques include, e.g., knife-edge bearings and ring beams. A knife-edge bearing is used to introduce vertical and horizontal forces into sheet piling profiles and steel

Universal adhesives are used across large surface areas to bond floor coverings to the substrate. They can consist of one or two components. Acrylate dispersions, epoxides, polyurethanes, silane-modif

DIN 4426 stipulates that anchoring devices for personal fall protection equipment as well as rope and rail systems need to be provided for building maintenance. Since there are no product standards or

Precast concrete products are products made of concrete, reinforced concrete or prestressed concrete which are manufactured at a location other than the final place of use. Precast concrete products a

These floor systems are composed of prestressed precast slabs finished with a structurally contributing in situ concrete overlay. Construction techniques for floors and walls, precast concrete product

When applying floor construction techniques comprising lattice girders, the floor is constructed from precast concrete slabs, lattice girders as reinforcement and an in situ concrete overlay. Precast

Surfaces for sports areas are single- or multi-layer floor systems with possible sport-relevant or protective features as well as other technical properties. Selection of the design, including the cov

Metal products and construction techniques

Smooth and profiled metal components are frequently used to execute roof or wall claddings. Alongside the classic trapezoidal sheet, individual solutions are also frequent. Metal products and construc

Other tendons include special prestressing components, e.g. for realising innovative construction techniques based using prestressing systems, also in combination with other manufacturing and reinforc

For external post-tensioning, the tendons lie outside the cross-section of the concrete member, but inside the envelope of the structure. These post-tensioning systems are used for prestressing concre

For internal unbonded post-tensioning, the prestressing tendons are arranged in a duct filled with a special corrosion protection system. These post-tensioning systems are used for prestressing concre

For internal bonded post-tensioning, the tendons are arranged in a sheath (tendon duct) which is grouted after the prestressing force has been applied. These post-tensioning systems are used for prest

This work area covers load-bearing plastic elements for swimming pools and water slides, in particular elements made of fibre-reinforced plastics. Plastics construction

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 thr

Reaction resin concretes or reaction resin mortars are used for strengthening and repairing timber structures, where applicable in combination with textile-reinforced rebars. Timber construction

Prestressing steel bars are used in various prestressing systems for concrete structures. Prestressing steel bars are manufactured in hot rolling mills (by quenching, cold-drawing or additional temper

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
