Steel · Concrete · Farm reservoirs
Line or reline steel, concrete and farm reservoirs with PVC, HDPE or bitumen systems matched to structure, water chemistry and how the reservoir is used.

RESERVOIR LINING
Reservoir lining helps protect stored water, reduce seepage and support reliable containment for farms, mines and commercial properties.
WHY IT MATTERS
PVC lining standard on Damtech steel tank builds
HDPE for large earth and process reservoirs
Torch-on for concrete and gunite structures
Relining without replacing sound steel shells
Outlet boots and penetration detailing
Nationwide installation crews
TECHNICAL DETAIL
PVC is flexible, cost-effective inside steel shells and smaller ponds. HDPE suits large surface areas and exposed earth batters with UV-stable grades. Bitumen torch-on bonds to primed concrete where sheet geomembrane cannot anchor to vertical rigid walls alone.
Corrugated galvanised tanks from Damtech include PVC lining, columns, inlet/outlet and overflow as standard. Relining replaces failed PVC without scrapping sound steel. It is common when outlets corrode or when the lining has aged to the point that seams, particularly at the floor, begin to fail.
Farm cement dams, irrigation canals and commercial water-retaining structures often receive torch-on bitumen after crack repair and moisture testing. HDPE may line earth embankments surrounding concrete walls where a hybrid system is required.
Choose PVC for tank interiors and compact ponds; HDPE for lining areas measured in hectares; bitumen where heat-bonded adhesion to concrete is required. We inspect first rather than defaulting to one catalogue product.
Failed internal liners, delaminated torch-on and outlet leaks are repaired or fully relined after substrate assessment. Pair reservoir work with our leaking dam repair service when earth dams and tanks share one water system.

OUR PROJECTS
Quality materials, expert installation and practical solutions for dam linings, waterproofing and water storage.
Torch-on bitumen waterproofing for a round concrete dam with an 18 m diameter. Approximately 255 m² circular base footprint, calculated from the 18 m diameter. This is a geometric base-area estimate — not the measured installed membrane quantity. Installed membrane area is higher once walls are included — roughly +130 m² if the wall is 2.3 m high all around (π × 18 m × 2.3 m), plus overlaps, detailing and waste.

FAQ
Yes, when the shell is structurally sound. We remove or overlay failed PVC, repair rusted outlets where needed, and commission with a water test.
Damtech steel reservoirs, in Z275 galvanised steel or AZ150 Aluzinc, are supplied with 550 gsm PVC lining as standard, with 850 gsm available on request. The liner, not the metal coating, is the water barrier. Capacity ranges from 11 kL to 500 kL+ with optional roofs to reduce evaporation.
Yes — typically with torch-on bitumen on prepared concrete. We assess cracks and moisture before membrane application.
