Cement Sheet Waterproofing Solution

Industrial sheet roof being treated against leakage

Cement sheet roofs usually leak at the overlaps, screw holes and hairline cracks rather than across the full sheet. Our treatment targets those points first and then protects the sheet surface with a coating system.

Common Problems We See

  • Dripping at sheet overlaps during rain
  • Rust and widening around screws and bolts
  • Hairline cracks across older sheets
  • Leakage near gutters, valleys and ridges

Our Solution

  • Cleaning of the sheet surface and gutters
  • Sealing of laps, screws and bolt holes
  • Crack treatment with reinforcement where needed
  • Protective coating over the treated area

How The Service Works

  1. 01

    Roof survey and leakage point marking

  2. 02

    Assessment of sheet and fixing condition

  3. 03

    Quotation with the treatment plan

  4. 04

    Joint, screw and crack treatment

  5. 05

    Coating, water test and handover

Benefits

  • Stops leakage without full sheet replacement
  • Protects stock and machinery below the roof
  • Reduces further rusting at fixing points
  • Suitable for large industrial areas
  • Warranty on completed work

Why Professional Treatment Matters

Sheet roofs need safe access, correct sequencing and the right sealing material for each joint type. Untrained patch work on sheets often shifts the leakage to the next lap instead of stopping it.

Warranty & Quality

Warranty of 2 to 7 years is provided depending on the sheet condition and treatment.
