Yes, our waterproofing systems include existing structures. Our team will assess the current condition of your roof or foundation and determine the best approach to apply bitumen or liquid rubber waterproofing with minimal disruption.
The installation time for a zinc reservoir varies depending on its size and complexity. Generally, a standard 250 kL reservoir installation can take between 3 to 5 days, including order placement, site preparation, construction and commissioning.
There is no single figure, and no lifespan is a guarantee. The PVC liner holds the water and usually sets the main maintenance interval. Published durability data for Z275 galvanised sheet give the outer zinc coating roughly 12–42 years at most inland (C3) sites and 2–5 years in severe (C5) conditions near the sea; Aluzinc lasts about three times longer on the outside. Water chemistry, site, base and maintenance all affect the result.
