Protection against aggressive environments
For the repair and protection of structures in contact with wastewater with domestic or industrial effluent, we have developed low-porosity mineral product technology with high chemical and mechanical resistance. This type of technology ensures a perfect result in terms of compatibility between the different substrates—concrete or steel—despite all inherent issues, from the high relative and surface moisture always present on site to the need to ensure variable reaction times depending on the case. One of the mandatory requirements is chemical resistance covering the pH range from 2 to 14 in anaerobic zones, as well as mortars resistant to hydrogen sulphide gas (H2S) up to 150 ppm continuously and 400 ppm temporarily in aerobic zones. For cases with aggressiveness levels above 400 ppm, we apply an anti-osmosis synthetic epoxy-based system that achieves continuous resistance to H2S up to 49,000 ppm, certified.
We also include, as a solution for areas with high levels of chemical attack, mechanical lining systems using BEKAPLAST HDPE plastics technology. This system was developed for the execution of a finished lining already at the concreting stage, or for repairs in degraded areas with the aid of fixing using our Ergelit V grouts.
For structures in contact with drinking water, we also offer the mineral mortar route; in this way, we ensure that the water is not contaminated, using 100% inorganic systems with porosity below 5%.
OTHER AREAS OF INTERVENTION
The range of services provided by Qi-Technologie covers a wide area of interventions in the field of engineering.
01 INJECTION TECHNOLOGY
Through resin injection technology, we are able to repair various pathological cases such as the sealing and restoration of cracks, area-wide waterproofing, the consolidation and stabilization of structures, the sealing of high and low water pressures, and resin injection in underwater activities.
02 CONCRETE AND METAL REPAIR AND PROTECTION
Following all necessary studies and the correct assessment of the state of concrete and metal structures, care must be taken regarding the compatibility of repair materials (strengths and moduli of elasticity), as well as their selection and application (in terms of alkaline mortars and synthetic products) to ensure the maximum durability of the structures.
03 UNDERWATER REPAIR AND PROTECTION
The complexity of underwater activity is a priority for us, which helps us develop specific products for the repair and protection of structures in underwater environments. With our diverse technologies, we are able to meet the highest demands in this field through mineral and polymeric systems.
05 CONTINUOUS TECHNICAL FLOORING
Beyond aesthetics, continuous technical flooring is the foundation for the diverse needs and requirements of the pharmaceutical, hospital, and food industries, with a focus on hygiene, conductivity factors, high chemical and mechanical resistance, and the ability to cover cracking.
06 EXPANSION JOINTS AND WATERPROOFING SYSTEMS
Our concern regarding waterproofing systems is to guarantee watertightness while also ensuring greater diffusion and thermal control in structures; our systems are designed for this guarantee. As a solution for the different needs in expansion joints, we have developed systems with various application typologies and ergonomics.
