Concrete replacement compounds for maximum assurance
Given their exposed location and the length of service lifetime expected of them, concrete cooling towers and chimneys require specific repair and surface protection systems tailored to their service requirements. With Nafufill SC 08, Nafufill GTS and Nafufill GTS-HS, we offer concrete replacement systems capable of meeting all such specifications. Whether structural strengthening or resilience against penetrative attack, the technical properties of these products are better than specified in any known standard, which means they offer the very highest level of assurance. As required in German code of practice VGB-Richtlinie 613, for example, these systems are unaffected by curing treatments. For small-scale repairs, concrete replacement compounds Nafufill KM 250 and Nafufill KM 250-HS deliver an excellent, trowel-applied solution.
Effective surface protection solutions
If exposed exterior concrete surfaces of cooling towers and chimneys are to be properly preserved over the long term, the surface protection systems applied need to withstand a variety of attack phenomena – both operational and environmental. With the modular MC-Color family of surface protection products, you can be sure of meeting all the demands likely to arise. Comprising the three product lines MC-Color Proof, MC-Color Flair and MC-Color Flex, the range has a solution to virtually any requirements profile: transparent, pigmented or crack-bridging, with graffiti protection as a further option. MC-Color even offers fast, economical system solutions for the curing of concrete replacements.
For more severely stressed areas both in cooling towers with flue gas discharge and in the downwash sections of chimneys, we offer you MC-DUR VS NR 3 and MC-DUR VS-PUR, products with a proven track record in more than 200 cooling towers. As an alternative, our latest generation of surface protection systems, MC-DUR 2496 CTP, can be applied quickly and safely under virtually any weather conditions.
Alternating wet and dry modes of chimney operation? With MC-DUR 1450 CP you have at your disposal a surface protection system that safeguards both mineral and steel substrates against the effects of acid condensate.
Exceptionally resilient and resistant coatings
Seeking permanent protection for your fire water and cooling tower collection basins or other structures exposed to contaminated water? You need look no further than MC-RIM Protect, a waterproof, osmosis-resistant mineral coating whose functionality and durability is decades-proven, with excellent protection afforded even under exposure to elevated chloride concentrations (e.g. in marine environments).
The coating of transformer oil sump tanks in existing buildings is an exacting task. Zentrifix F 92 is impervious to transformer oil and contaminated water, yet open to water vapour diffusion – especially essential if there is no damp-proofing. It also offers excellent crack-bridging properties in compliance with the strict requirements of, for example, Germany’s Water Resources Act. This protective product fulfils every requirement and has been successfully applied in a great many reference projects.
Mechanically resilient, chemically resistant, conductive or insulating
The demands placed on floors are as varied as their uses. Manufacturing facilities, chemical collection basins, battery centres, control rooms – they all have their specific requirements. With our MC-DUR floor coating systems, we are able to deliver the right solution to give elevated mechanical resilience and chemical resistance, with the choice of conductive or insulating as a further option.
Need a fast fix? Say with a Friday afternoon start and productive operations resuming on the following Monday? Then take a look at MC’s complete, rapid-application floor system consisting of high-strength reprofiling MC-Floor Screed, the MC-Floor Connect range of noise-reducing jointing strips, and the fast-curing, exceptionally resistant high-performance coating MC-Floor TopSpeed.
The newly developed MC-Floor Screed industrial flooring system offers a reliable solution for the rapid repair of heavily used industrial surfaces, with rapid hardening and high wear resistance among its attributes. Meanwhile, the MC-Floor TopSpeed system enables industrial floors and external surfaces to be installed within a few hours, becoming fully load-resilient after just 48 hours.
Sealing cracks and cavities and preserving the structure
It is not uncommon for cracks in reinforced concrete structures to run deep into the reinforced zone or even separate entire components, with – if left untended – cavities also developing. Contaminants such as water or chlorides are then able to penetrate unhindered into the structural fabric, often causing serious damage likely to jeopardise the stability of the entire construction. With our MC-Injekt injection systems, you can reliably and permanently seal cracks, joints and cavities in concrete components, reinstating the structure’s functional integrity and enhancing its durability.
Restoring structural strength economically
Our MC-DUR CFK Lamellen (CFRP strips) and MC-DUR CF Sheets (CFRP non-woven web wrapping) serve to return weakened structures – particularly those with inadequate, corroded or damaged reinforcement – to their original strength at comparatively low cost and with relative ease.
Flexural reinforcement can be readily achieved both with MC-DUR CFK Lamellen glued into slots or onto the component’s surface, and by wrapping with MC-DUR CF Sheets. And these systems can also be ideally combined with the structurally effective concrete replacement systems of the Nafufill series to achieve a truly synergistic solution.
Systems for underground infrastructure maintenance and repair
Efficient rehabilitation of sewers and manholes
Need to refurbish your manholes, sewers or grease traps? Easy to apply and exceptionally resistant to highly aggressive mechanical and biochemical attack, our product systems from the ombran product family offer all you need for the entire spectrum of rehabilitation works involving underground and accessible sewerage structures and components.
