Flour Mill Silo Waterproofing
Tauranga
Water was tracking between the steel silos and their concrete plinths. A flexible Rust-Oleum Noxyde® membrane, reinforced with MMP Panel Bond Bandage, sealed the joint permanently — without replacing a single silo.
Moisture trapped at the base
Water ingress around the base of the steel silos was allowing moisture to penetrate between the steel tanks and the concrete plinths. Over time this trapped moisture was causing corrosion, rust and deterioration around the base of the silos, threatening the long-term integrity of the structure.
Replacing the silos wasn't an option, so a durable waterproofing solution was required to stop water penetration while allowing for the natural movement between the steel and concrete.
Bandage, then Noxyde®
After removing the existing failed sealant, the joint between the steel silos and concrete plinths was reinforced using an MMP Panel Bond Bandage. This created a strong, flexible bridge across the joint before the entire area was encapsulated with Rust-Oleum Noxyde®.
The Noxyde system forms a seamless elastomeric waterproof membrane that bonds to both steel and concrete, creating an airtight and watertight seal. Unlike conventional sealants, the flexible membrane expands and contracts with structural movement, helping to prevent cracking, splitting and future water ingress.
A joint sealed for the long term
The completed waterproofing system permanently sealed the vulnerable joint between the silos and their concrete foundations, preventing further moisture penetration while protecting the steel against corrosion.
By combining the reinforcing strength of MMP Panel Bond Bandage with the long-term flexibility of Rust-Oleum Noxyde®, the flour mill gained a durable waterproofing solution designed to withstand movement, harsh weather and years of industrial service.

NoxydeNoxyde Anti-Corrosion Coating
Paint straight over prepared rust, stopping corrosion for decades.
Noxyde is the only anti-corrosion waterproofing membrane on the market that can be applied directly over clean, prepared rust — no separate primer required. For over 29 years it has protected New Zealand's most severe coastal environments, from saltwater estuary bridges to iconic steel roofs. It is also used to extend the life and safely encapsulate asbestos roofs, locking fibres in place and adding decades of waterproof protection without the cost of removal.
