Tank Waterproofing Melboume

Why Waterproof Your Tank?

  1. Prevent Structural Damage
    Cracks, voids, or seams in your tank can lead to leaks, corrosion, rust, and further degradation. Effective waterproofing stops water infiltration and protects your tank’s structural integrity.

  2. Eliminate Contamination
    Water leaving your tank via micro-cracks can allow soil, insects, or tree roots to enter. A fully sealed tank keeps your stored water clean and safe.

  3. Cut Long-Term Costs
    Solving leaks early through waterproofing avoids costly repairs, full drain-and-repair jobs, or tank replacement down the line.

Looking to protect your investment and extend the life of your concrete or steel water tank? At TankSeal, our expert team specializes in premium tank waterproofing services across Melbourne, ensuring long-term durability and leak-free performance for agricultural, residential, and commercial water storage systems.

Our Melbourne Waterproofing Solutions

1. Comprehensive Inspection & Leak Diagnosis

We begin with a detailed assessment—checking concrete or steel tanks for cracks, hairline fractures, corrosion, joints, and aging seals.

2. Surface Preparation

Effective waterproofing starts with cleaning. Our team power-washes and acid-etches surfaces to remove old coatings, mineral scale, algae, and grease.

3. Crack Injection & Repair

Small cold-jointed cracks? No problem. We inject elastomeric resins or injectables to seal them before coating application.

4. Industry-Grade Waterproofing Coatings

We apply tank-grade waterproof membrane systems that bond chemically to concrete or steel, creating durable, flexible, and impermeable barriers. Choose from:

  • Membrane coatings — single-component elastomeric layers that expand and contract with movement

  • Cementitious systems — mineral-based, ideal for active leak control and internal waterproofing

5. Re-Coating, Lining & Re-Sealing

For previously lined or coated tanks in Melbourne needing maintenance, we strip old coatings, prime, and re-apply waterproof membranes atop fresh substrates.

6. Joint and Penetration Sealing

We expertly seal around inlet/outlet pipes, overflow outlets, access hatches, and control devices to prevent leakage in high-risk areas.

7. Final Inspection & Quality Assurance

Post-application, we perform water-fill and leak-testing, ensuring the waterproofing system meets performance standards. We issue a detailed report and warranty documentation.
