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

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

Penetration seals are used in fire-stopping and fire-sealing measures when services, such as pipes and cables, penetrate fire-resistant walls and/or ceilings. Penetration seals prevent the spread of f

Screw piles comprise one or more rod-shaped foundation elements, generally made of steel, which - depending on their geometry - are driven, pressed, or screwed into the ground. Load is transferred pri

Earthen construction comprises construction products, such as earth plasters and earthen boards. In addition, load-bearing and non-load-bearing walls can also be constructed as rammed earth walls. In

In recent years, the industrialisation of earth block production has led to further technical development of earth block masonry. Earth block masonry is made from earth blocks bonded by earth mortar.

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

Thermoplastic tanks are especially suitable for storing certain liquids hazardous to water because they often have a more favourable corrosion behaviour than metal tanks and hence are resistant to var

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

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

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

Waterproofing sheets and membranes are available for various applications (e.g. for roofs or elements in contact with soil). Waterproofing sheets and membranes can be divided into plastic and bitumen

Expansion joints for road bridges are designed to accommodate movements between the bridge segment and bridge abutments. The dimensioning of the joints is derived from the required movement capacity a

Structural bearings are components that allow for relative rotation of parts of structural works, transfer loads and permit or prevent displacements in one or more directions. The most common bearing

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

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

Shear connectors, such as anchors, power-actuated fasteners or composite dowel beams, are used in composite members to connect the steel and concrete components in a form-fitting manner. When the comp

Space frames are three-dimensional frame structures which serve as roof or building structures. They usually consist of frame members (tubes) and nodes. At least two frame members are joined at a node

A hold-open device is a system of devices or device combinations suitable for the controlled disabling of the function of closing devices. Hold-open devices may be used on fire doors, smoke control do

Jet our high-pressure grouting serves to produce structural elements (jet-grouted elements and/or jet-grouted bodies of soil made of jet-grouted elements) in the soil. These procedures are soil-streng

Soil reinforcement systems serve to secure escarpments. Steel wire meshes and grids, steel strips and geotextiles are used as reinforcing elements. They act via friction and interlocking with the surr

For these wall construction techniques, precast concrete elements fitted with reinforcement are filled with in situ concrete. For applications comprising precast elements, lattice girders may be used
