AREAS OF INTERVENTION

01 INJECTION TECHNOLOGY

Using resin injection technology, we can repair various types of defects, such as crack sealing and restoration, area waterproofing, consolidation and stabilisation of structures, sealing against high and low water pressures, and resin injection for underwater works.

AREAS OF INTERVENTION

02 CONCRETE AND METAL REPAIR AND PROTECTION

After all the necessary studies and a proper assessment of the condition of concrete and metal structures, care must be taken to ensure compatibility of repair materials (strengths and elastic moduli) when selecting and applying alkaline mortars and synthetic products, so as to maximise the durability of the structures.

AREAS OF INTERVENTION

03 UNDERWATER REPAIR AND PROTECTION

The difficulty of underwater work requires us to develop precise products for the repair and protection of structures. With alkaline and synthetic systems, we can meet the highest demands in this field.

AREAS OF INTERVENTION

04 REHABILITATION IN THE WATER AND WASTEWATER INDUSTRY

For structures in permanent contact with water—intake, potable or wastewater—we can offer a range of fast systems with high chemical resistance from pH 0 to 14, including hydrogen sulphide gas (H2S), highlighting their compatibility with moisture in this type of structure.

AREAS OF INTERVENTION

05 CONTINUOUS TECHNICAL FLOORING

The most important aspect in flooring is the different needs and requirements of industries, from ensuring hygiene to conductivity, high chemical resistance and wear resistance, also including crack prevention.

AREAS OF INTERVENTION

06 EXPANSION JOINTS AND WATERPROOFING SYSTEMS

In our waterproofing systems, our focus is to ensure watertightness while allowing the water vapour diffusion permeability required in building construction. For large-area works, we provide highly durable, certified systems for vehicle traffic.
