For Waiheke Island homes, rural properties and high-capacity rainwater storage needs ( 25-100,000 litres+) , a timber tank is a smart, sustainable and practical choice.

When acidic water sits inside a concrete tank, a chemical reaction occurs. Classic signs of degradation include rough, exposed aggregate on the inside walls where the smooth cement paste has dissolved. Installing a polyethelyne tank liner acts as a complete physical barrier. It stops the acidic water from ever touching the concrete again, effectively sealing existing leaks and halting the leaching process entirely.
