Concrete Repair
Product information "Concrete Repair"
Building renovation through professional concrete repair
Concrete repair and restoration are used in a wide variety of building renovation applications. These include:
- Building construction: Residential and office buildings, shopping centers, public buildings and industrial facilities benefit from refurbishment to ensure the safety and aesthetics of the structures.
- Civil engineering: Bridges, tunnels, and roads are often exposed to extreme environmental conditions. Concrete repair contributes to increasing load-bearing capacity and extending service life.
- Infrastructure structures: Ports, airports and railway facilities require regular concrete repairs to ensure their functionality and safety.
- Hydraulic structures: Dams, reservoirs and sewage treatment plants are often exposed to aggressive water and weather conditions, which is why professional concrete restoration is essential.
- Historic preservation: Historic buildings and monuments require special concrete repair techniques to preserve their historical value and structure.
- German Armed Forces: Many military facilities, such as barracks, bunkers, garages, workshops, logistics centers, and naval port facilities, are partially constructed of concrete. Regular renovations help to repair cracks and damage and ensure the long-term stability of these structures. Taxiways, access roads, and landing strips used at military installations are subject to heavy wear and tear. Professional concrete restoration ensures safe and durable traffic surfaces.
Remediation of salt-contaminated concrete: Effective methods for repair
Concrete, although robust and versatile, is susceptible to environmental influences. Chlorides, which often penetrate the concrete through the use of road salt in winter, are particularly critical. These salts can reach the steel reinforcement and trigger corrosion processes. Corroding steel reinforcement causes the concrete to expand, crack, and gradually weaken the entire structure. This process can go unnoticed for years and, in the worst case, lead to the failure of the structure.
The condition of concrete structures, especially bridges, has increasingly come under scrutiny in recent years. The recent bridge collapse in Dresden provides a disturbing example of the potential dangers of salt-laden concrete structures. This incident highlights the enormous risks that can arise from gradual concrete corrosion and the long-term effects of salt deposits.
The repair of salt-contaminated concrete requires specialized techniques. Modern methods for desalination and stabilization of concrete aim to prevent further corrosion and repair existing damage. These methods employ special mortars and injection techniques that draw the salts out of the concrete and stabilize its structure.
The repair of salt-damaged concrete is an important step in extending the service life of concrete structures damaged by chlorides and other aggressive substances. Concrete regularly exposed to road salt tends to develop cracks and corrosion damage to the steel reinforcement. This damage weakens the structure and can lead to costly repairs or even collapse.
The professional restoration of salt-damaged concrete involves several steps. First, the condition of the concrete is examined to determine the depth of the salt contamination and the extent of the corrosion. Special desalination processes are then used to remove the salt from the concrete. Finally, the concrete is reinforced with special repair mortars and protective systems to prevent further corrosion.
Repairing salt-damaged concrete structures can prevent costly new construction while ensuring the long-term stability and safety of existing structures. Professionals utilize innovative techniques to extend the lifespan of bridges, facades, and other concrete structures, protecting them from future damage.
Whether in the private, commercial or public sector, professional concrete restoration offers the solution to numerous challenges and ensures the functionality and aesthetics of the buildings.

Flexible fire water tanks and storage tanks, e.g. with a volume of 100 m³ The advantages of above-ground flexible storage tanks for firefighting water are: Quick, easy and immediate installation. Significantly lower investment costs than concrete or steel cisterns or underground fire water tanks No maintenance or intervention required. Freestanding. Constant water level: No evaporation or loss of volume. Can be used temporarily or permanently depending on the fire protection concept. Mobile and reusable at changing locations Clean water without microalgae or larval growth due to the absence of light and air pockets. No air pockets, therefore no oxidation problems. No light penetration, no contamination: The water always remains perfectly clean. (Upon request, we can also supply residue-free evaporating spray cleaner for degreasing, as well as elastic adhesive and drinking water-safe silicone grease from WEICON.) Areas of application for fire water tanks Fire brigade deployment sites (e.g. forest, industrial and large fires) Firefighting water reserve for industrial, logistics and commercial enterprises Temporary fire water supply on construction sites Supplementing or replacing missing fire hydrants in rural areas Energy plants, substations, PV and wind farms Events with fire safety regulations Technical features of the foldable fire water tank Robust, multi-layered high-performance plastic (PVC / PE) UV, frost and weather resistant Suitable for large water volumes as a fire water reserve With Storz A or B connections , suction and filling nozzles Suitable for pump operation and fire water supply The closed design reduces contamination and evaporation. Fire water tanks for fire protection & authorities The collapsible fire water tank is suitable as a component of fire protection and fire water concepts that comply with official regulations. It can be used as a temporary or permanent fire water container , a replacement solution , or an additional reserve – e.g., during renovations, changes of use, or temporarily increased fire water demand.Note: Recognition as a fire water reserve is dependent on the project and the authorities. Coordination with the fire department, fire protection planner, or permitting authority is recommended. Folding tanks as an alternative to fire ponds The collapsible tank system is closed, meaning that, unlike fire ponds, there is no risk of drowning for children. Furthermore, the closed design prevents silt accumulation, significantly reducing maintenance. Extensive upkeep is unnecessary, making maintenance simple and cost-effective. Technical specifications: The fire protection reservoir offers a reliable and adaptable solution for storing fire-fighting water. It is available in various sizes and can hold a volume of up to 2000 m³. Its design allows for quick and flexible installation. The reservoir is designed for a wide temperature range from -30°C to +70°C. This means the cisterns can be used reliably in extreme sub-zero temperatures down to -30°C as well as in hot summer temperatures. Even in freezing conditions, the water inside the fire-fighting cistern remains liquid and ready for use. There are three connection options for the foldable fire water storage tank: Mobile, above-ground version for direct extraction with suction connection / shut-off valve for mobile collapsible tank with Storz A coupling (e.g. for temporary use or the risk of forest fires in summer) – with an additional optional heat-insulating valve heat protection sleeve that prevents the outlet valve from freezing at moderate sub-zero temperatures. Forest-free version with hydrant and suction connection with Storz-A connection ND100 according to DIN 14244 (with underground, dry pipeline to the hydrant) Frost-free version with connection to customer-provided underground pipeline The frost-proof, underground extraction point (connection option 2 with hydrant or connection option 3 with customer-provided underground pipeline) ensures a reliable water supply at all times, regardless of the current weather conditions.
