Building repair

Comprehensive services for the repair of buildings and concrete

Building repair is crucial for a long-term cost and energy-efficient construction project. Targeted measures can improve the functionality, safety, value retention and aesthetics of your building. With PORR's many years of expertise, you have a strong and internationally active partner at your side. As a certified “repair specialist” of the Austrian Building Technology Association, we guarantee quality and expertise in every execution and every specialised area.

Our product areas cover a broad spectrum, from highly technical industrial facilities to sensitive monument protection projects and sustainable residential construction. Whether you are a small business or a large corporation, we offer comprehensive services to meet your requirements.

Our comprehensive services include consulting, structural investigations, repair concepts, cost estimates, construction scheduling, in-house monitoring and documentation for holistic support of your projects. With a comprehensive concept, we can not only support you in the planning and evaluation of construction projects, but also offer a transparent cost estimate for customised solutions. Construction process planning and self-monitoring ensure the smooth realisation of projects with high quality and efficiency. The detailed documentation of all processes enables seamless tracking.

We offer a wide range of services in this area: Synthetic resin applications and coatings for terrace and balcony waterproofing, car park coatings, surface protection systems, industrial floor coatings, as well as dissipative and decorative floor coatings. With these options, we provide your project with long-term protection against moisture, weathering, wear and chemical attack.

We offer a wide range of services in this area: Synthetic resin applications and coatings for terrace and balcony waterproofing, crack and joint sealing, masonry drying and consolidation, parking garage coatings, surface protection systems, industrial floor coatings and decorative floor coatings. With these options, we provide your project with long-term protection against moisture, weathering, wear and chemical damage.

Our experts offer specialised injections for structural reinforcement, strengthening and sealing of concrete components in building construction, civil engineering and infrastructure construction as well as in municipal buildings. By effectively sealing and draining masonry in residential and heritage buildings, we protect against moisture damage and thus preserve historic buildings. Our modern techniques and years of experience guarantee reliable solutions for the long-term stability and safety of your buildings. Another field of coating technology is in the area of municipal drinking water supply (tanks) and waste water disposal in sewage treatment plants. Here we offer synthetic resin and cement-based protection systems, including all the necessary preparatory work and system components.

We carry out plastering work in various specialist areas, including machine plastering, historical plastering, restoration of listed plaster surfaces and full thermal insulation work to improve your energy balance. In particular, traditional techniques for restoring and preserving historic plaster surfaces are challenging processes in which we specialise.

Wherever a building structure made of concrete or steel comes into contact with aggressive substances and liquids, there is a risk of corrosion (steel) or destruction (concrete). Acid protection is therefore necessary in all industrial plants that work with chemicals. This is because the mechanical, thermal or chemical resistance of coatings for floors and walls is often insufficient, meaning that a combination coating consisting of a sealing layer and acid-resistant cladding must be used.

Joints are weak points in any construction, especially in concrete floors or flooring, leading to all kinds of damage to the building or transport equipment that can be avoided. The patented Ulbrichfuge® is the perfect solution for necessary structural and expansion joints. The permanently elastic, liquid plastic-based joint does not require separate metal profiles and has a high abrasion resistance against wet wear. In addition, the Ulbrichfuge® creates a flat, smooth transition and thus a surface that is gentle on vehicles and reduces noise. In addition to the short processing time, it impresses with its resistance to temperature and chemicals. Ulbrichfuge® is the perfect solution, particularly in car parks and transport and logistics areas where floors are exposed to high loads. As Ulbrichfuge® is also food-safe, fungus- and germ-free, it should be the first choice in food and frozen food storage areas. Installation down to -25°C included.

Our substrate preparation includes high-pressure water jetting up to 2500 bar, sandblasting, dry ice blasting, milling and diamond grinding for optimum substrate preparation. With our high-pressure water blasting technology, surfaces are gently and sustainably cleaned with clear water under high pressure and prepared for subsequent repairs without causing unnecessary structural damage. When it comes to removing old coatings, our water, dry ice and sandblasting processes are the right choice. Milling and diamond grinding are primarily used for the mechanical processing of surfaces in preparation for coating work and repair work on horizontal surfaces. Thanks to these efficient and precise techniques, we can clean and process almost any surface for you.

Specialised applications such as CFRP fins and CFRP sheets as well as cathodic corrosion protection are also part of our range of services. CFRP louvres and CFRP sheets are used to improve or increase the structural integrity of buildings. We use cathodic corrosion protection to prevent or slow down corrosion of metallic structures (reinforcement) due to the influence of chlorides in the event of electrical voltages. With us, your project is in the best hands.
