Rebuilding Materials
Rebuilding materials are used to restore wall-thickness loss or repair damaged surfaces on both metallic and nonmetallic substrates. These materials are often paired with immersion-service linings to provide complete protection.
Selection depends on several factors, including:
- Required chemical resistance
- Operating temperature of the substrate
- Surface cleanliness and preparation levels
- Other application-specific conditions

Rebuilding Materials Testing
- Mechanical Properties – High Young’s modulus and compressive strength
- Erosion Resistance (Taber sliding & impact) with minimum volume loss
- Corrosion Resistance – Salt spray for over 1000 hours with no signs of failure
- Mechanical adhesion – Pull-off adhesion values as high as 5,200 psi on grit-blasted steel
Flange Face Forming
Technique used for retrofitting flange faces damaged by the isolated or combined action of chemical attack, crevice corrosion, galvanic corrosion, and high-pressure steam among others
Key Benefits:
- Several rebuilding materials available based on temperature, chemical service, and return-to-service times
- No hot work
- No need for replacement parts
- Simple application
- No need for specialized tools
- Reusable formers
- Short downtime
Damaged Shaft Repairs
Rebuilding materials can be used to repair worn shafts that have been damaged due to misalignment, vibration, corrosion, wear, loss of oil film, and other operating conditions.
Missing sections or edges require framework to support the Belzona rebuilding material.
Framework can be achieved by bolting or metal plates.
Pump Internals Rebuilding
The internal parts of pumps can also suffer from various forms of erosion, corrosion, or their combined effect.
Or by bolting expanded metal.
Rebuilding materials are then used over the framework and templates can be used to check for clearance.
Rubber Repairs
Belzona offers a wide range of rubber repair solutions, addressing issues from erosion and mechanical damage on floating hoses and marine fenders to tears, gouges, and wear on conveyor belts.
