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

Metal pipes and the associated fittings, seals and valves used in the conveyance of liquids hazardous to water must meet certain tightness and media resistance requirements set out in water legislatio

Metal sealings are installed in collecting devices made of concrete to make them liquid-tight. Liquid-tight collecting trays and devices are enclosures serving to meet the requirement for secondary co

Single-skin tanks made of metal (mainly steel) for the above-ground stationary storage of liquids hazardous to water are available in various volumes and shapes. Common variants include: vertical cyli

Grease separators serve to separate grease from commercial wastewater. Separator systems

Separator systems for light liquids serve to separate light liquids of mineral origin from commercial wastewater. Separator systems

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

Insulating render systems contain, apart from the usual render components, aggregates such as polystyrene, perlite or an aerogel. The insulation performance achieved in this way is comparable to that

Drainage pumps for drainage systems are used for lifting greywater or foul water, which can contain different components of organic, inorganic or mineral origin. Drainage pumps for drainage systems ar

Membrane structures are composed of thin, fabric-like materials. Due to their low self-weight, they are suitable for spanning large areas. They are used, e.g., as space-dividing, thermally insulating

Retrofit kits are systems consisting of multiple components which are installed on site in existing tanks forming part of the wastewater treatment plant. The retrofitted small wastewater treatment pla

Small wastewater treatment systems serve to purify domestic foul water from buildings with up to 50 inhabitants. The wastewater is treated using physical and biological processes. Small wastewater tre

Steel and steel composite sealing systems serve to make retaining systems such as collecting rooms, collecting trays and surfaces in storage, filling and handling facilities for substances hazardous t

Amalgam separators serve to treat wastewater containing amalgam residues from treatment units in dental practices. Separator systems

Non-return valves serve to prevent backflow of rainwater or wastewater from the connected sewer system into the parts of the property drainage system lying below the backwater level. Equipment for dra

Sewage lift stations are used to pump sewage from below the backwater level upwards so it can be drained via the public sewer system. Sewage lift stations usually have cutting devices for reducing the

These special thermal insulation products may be used as thermal insulation or substitutes for masonry facing and thermal insulation on stationary heating appliances assembled on site (e.g. stoves and

These systems serve to treat stormwater run-off from transformer stations and retain insulating oil (transformer oil). Systems for limiting hydrocarbons in mineral oil containing wastewater

Wastewater treatment systems for compressor condensates serve to treat wastewater resulting from compressed-air generation in compressors to such an extent that the treated effluent can be introduced

Wood preservatives for preventive treatment are used to prevent infestation of wood and wood-based materials by insects, fungi and other wood-destroying organisms. Wood preservatives for curative trea

Punched metal plate fasteners are metal plates with integral projections punched out in one direction perpendicular to the plate plane. They are used in timber construction to permanently connect timb

In modified timber, the durability of the wood is improved by chemical or thermal treatment. Timber construction

Mastic or roller-compacted asphalt sealing layers are used in storage, filling and handling facilities for substances hazardous to water (SFH facilities) to create load-bearing, liquid-tight, sealed s

Where necessary, penetrations are subsequently sealed against water ingress, e.g. penetrations for roof installations or for cable or pipe penetrations in basement walls; subsequent sealing of formwor
