Gut informiert mit unseren FAQ
Concrete repair encompasses all technical measures aimed at repairing damaged concrete members. The aim is to professionally repair damage to the concrete and the reinforcement in order to maintain or restore the load bearing capacity, durability, safety and serviceability of the construction works in the long term.
The most common causes of damage to reinforced concrete are reinforcement corrosion resulting from carbonation or chloride ingress, frost and de-icing salt exposure, chemical attack, mechanical stresses, and design and construction errors. These factors can cause cracks, spalling of the concrete and a loss of load bearing capacity and durability.
Since the beginning of 2021, the Technical Rule on Maintenance (TR Instandhaltung) issued by the Deutsches Institut für Bautechnik (DIBt) has formed the authoritative basis for concrete repairs in Germany. For producers of repair products, the requirements of the ten-part DIN EN 1504 series of standards serve as the binding basis. However, for repair works affecting the load bearing capacity and stability of concrete members, Part 3 of the DAfStb Repair Guideline remains the authoritative reference. Further guidance on the technical regulations relevant to the verification of structural stability is also provided in the DBV information sheet ‘Building Renovation – A Guide’.
Concrete repair involves damage analysis, preparation of the substrate, protection of the reinforcement, the optional application of bonding agents, the application of concrete replacement systems, and the final surface protection. The aim is to repair and ensure the load bearing capacity, durability and serviceability of the construction works in the long term.
The bond strength test (bond strength test) is an essential part of maintenance and repair work on concrete structures and is required during both the design and construction phases.
During the planning phase, it serves to assess the condition of the existing concrete and to select suitable repair systems and materials in a way that is both economically and technically sound.
During the construction phase, it ensures that the concrete substrate is suitable for the planned measures and that the requirements of the applicable regulations are met.
Furthermore, the test is also required prior to the application of surface protection systems, although the required surface tensile strength may vary depending on the specific application.
StoCretec offers tailor-made solutions for virtually any challenge in concrete repair. The high-performance range includes corrosion protection systems, bonding agents, concrete repair materials for a wide variety of application methods, grout, fine-finish fillers, as well as surface protection and curing systems for a permanently secure repair.
A bonding agent is a mineral or polymer-based adhesion promoter that ensures a permanent bond between the existing concrete substrate and the concrete replacement material.
Our product range
We offer a range of excellent solutions for the protection of concrete constructions to suit requirements for industry, traffic and hydraulic structures, and the housing industry, as well as other areas including multi-storey car parks and wastewater treatment plants.
Our repair systems and solutions for the protection of concrete constructions are precisely designed for a wide range of application areas and specific requirements.
- Product and system solutions for the protection and repair of concrete facades, bridges, tunnels, power plants, wastewater treatment plants, etc.
- Repair mortar and protection against corrosion for the repair of concrete structures
- Coatings and sealing coats for long-lasting surface protection
- Products for securely filling cracks in concrete members Joint repair: products, materials, and systems for securely sealing joints
Preserving construction works in our transport infrastructure, such as tunnels and bridges, is one of our goals. Benefit from our intelligent and smart solutions offering the following advantages:
- Surface protection of reinforced concrete structure with deep-acting hydrophobic agents
- Protection of the building fabric and quick drying of damp concrete surfaces
- Reliable sealing of bridge decks
- Cost-effective and long-lasting strengthening structures made of CFRP plates
- Concrete repair at the highest level incl. safety in the event of a fire
- Injection of cracks: restoring stability and functionality
- Innovative tunnel coating: cost-effective, durable, and environmentally-friendly
Hydraulic structures fulfil important functions for our daily life, for the economy, and for ecology. They are subjected to enormous climatic and mechanical stresses. Our goal is to preserve the building fabric and to repair it if it becomes damaged. This requires corresponding renovation concepts and high-performance solutions – which is exactly what we can offer, tailor-made for every requirement:
- Repair products and systems which guarantee the long-term functionality of hydraulic structures
- Durable concrete repair products for general civil engineering
- Diverse and efficient surface protection for prevention
- Approved sprayed mortar solutions for hydraulic structures Crack injection systems for securely filling cracks in concrete members
Concrete protection also plays a significant role in wastewater treatment plants. Construction works in wastewater treatment plants in particular are often exposed to extraordinary effects. If the applied concrete is not resistant enough, surfaces may become damaged by:
- Frost and de-icing salt
- Chemicals
- Sulphuric acid corrosion
What’s more, our range includes products and systems for all buildings surrounding wastewater treatment plants. From coatings for usable areas and surface protection for facades through to floor coatings in staircases and common rooms: we offer every solution from a single source.
As a reliable partner for the housing industry, our product range covers all aspects of your new building, repair, or modernisation project.
Benefit from high-performance coating and repair systems to design and create durable and attractive facades and balconies.
Our specially designed coating systems provide protection for floor areas in staircases, cellars, and underground car parks, perfectly combining functionality and aesthetic appeal. Always precisely tailored to the specific requirements of the housing industry.
Hardly any other type of building is as wide-ranging in terms of size, shape, and stress as multi-storey car parks and underground car parks – from single-story systems in multiple dwellings to vast parking complexes at airports. We also have a diverse range of solutions for the various tasks and challenges associated with protecting these structures.
Effects of the weather, harmful substances, and mechanical stresses can cause damage to construction works made from reinforced concrete and repairs must meet the complex requirements of multi-storey car parks. The requirements for car park coatings are also highly diverse. Any coating needs to provide reliable and lasting protection against the ingress of water and any dissolved de-icing salts into the reinforced concrete floor. Our tried-and-tested solutions for multi-storey car parks and underground car parks fulfil a diverse range of requirements in terms of:
- Concrete repair
- Surface protection for walls, supports, and ceilings
- Strengthening structures
- Floor coating
- Cathodic protection
- Crack repair
- Colour design
