Coatings and Repair Composites for Water and Wastewater Facilities

Belzona epoxy-based metal and concrete repair composites and coatings are specifically designed to repair and protect water and wastewater treatment facilities and equipment.

Belzona offers a wide range of epoxy-based repair composites and coatings to repair and protect water and wastewater treatment facilities and equipment from common problems occurring in the industry, including erosion, corrosion, chemical attack, mechanical damage and leaks. Belzona solutions minimize downtime, labour and replacement costs and can extend assets’ life for many years.

Repair and efficiency enhancement of fluid management systems

Belzona provides a wide range of epoxy repair materials, which can be used to repair fluid management systems damaged by the effects of erosion, corrosion and chemical attack. Our solvent-free materials such as Belzona 1111 (Super Metal) are formulated to repair deteriorated equipment including pumps, pipes and valves to their original profile and will bond to almost any metal surface. After the equipment is restored, epoxy coatings such as Belzona 1341 (Supermetalglide) can be used to provide outstanding erosion and corrosion resistance as well as improve efficiency of the equipment from up to 7% on new pumps to 20% on those in service, which will greatly reduce operating costs.

Concrete repair of sewage systems

Our concrete repair materials and coatings are specifically designed to repair and protect sewage systems from common problems such as concrete spalling, wear and chemical attack as a result of hydrogen sulphide attack, heavy load and erosion. Belzona epoxy concrete repair materials such as Belzona 4111 (Magma-Quartz) can repair spalling concrete on equipment including settlement tanks and clarifier troughs, ensuring fast and permanent solution. Facilities damaged under heavy load like primary settlement tanks can be repaired using high strength materials such as Belzona 4131 (Magma-Screed) and Belzona 4111 (Magma-Quartz), which will strongly bond to existing concrete.

Our range of brush and spray-applied coatings such as Belzona 5811 (Immersion Grade) provide long-term protection of variety of equipment against corrosion and chemical attack as well as ensuring easy and safe application thanks to its solvent-free formulation.

Leak sealing

Expansion joints of tanks and clarifiers can be easily sealed in situ using Belzona elastomers Belzona 2211 (MP Hi-Build Elastomer) and Belzona 2111 (D&A Hi-Build Elastomer). Live leaks can be instantly sealed using our epoxy repair composites such as Belzona 1291 (ES-Metal) without the need for any specialist tools or welding. In order to protect and add strength to damaged pipes, our cold-curing pipe wraps system incorporating Belzona 1111 (Super Metal) can be used, which provides permanent pipe restoration solutions. Additionally, Belzona provides protection of flanges and joints in equipment, using our high strength epoxy materials such as Belzona 1111 (Super Metal) and Belzona 1121 (Super XL-Metal).

Repair and protection of mechanically damaged equipment

Expensive repair or replacement of mechanically damaged equipment such as shafts can be avoided using Belzona’s epoxy repair materials, which allow in-situ repairs without disassembling the shaft, therefore minimizing cost and downtime. Epoxy coatings such as Belzona 1321 (Ceramic S-Metal) and Belzona 1811 (Ceramic Carbide) are excellent at providing erosion and abrasion resistance to equipment including grit separators, augers and fluid flow equipment, extending the life of the assets.

Protection from chemical attack

Belzona epoxy repair composites and coatings provide outstanding chemical resistance against a wide variety of harsh chemicals for equipment including chemical storage tanks and sludge dump trucks. For instance, coatings such as Belzona 4311 (Magma CR1) are ideally suited to protect secondary containment areas from chemicals including acids and alkalis and Belzona 5811 (Immersion Grade) is excellent for equipment operating under continuous immersion.
