We specialise in concrete water tank repairs using specialised cement-based products for the restoration of cracks, seeps and holes that cause water leakage and loss.
To ensure a leaking tank is repaired properly, the remedial work is performed from inside the tank, thereby protecting the steel skeleton from further water damage.
Over a period of time, the inside surface of water tanks become porous. This is due to rainwater being slightly acidic. This acidic water takes lime from the cement to reach a neutral pH level of water.
Lime is the critical bonding agent in cement, so once it disappears the inside of the tank becomes rough, sandy and porous.
Having lost that critical seal, moisture seeps into the steel skeleton. Once steel comes into contact with water, it oxidises and creates rust. Rusting steel expands causing cracks.
