Stone restoration involves cleaning, repairing, and preserving natural stone surfaces affected by weather, pollution, and biological growth. Over time, these elements can damage or stain stone, making professional stone cleaning essential for both appearance and longevity.
At A.R.C. Stone Masonry, we specialise in restoring heritage and residential stonework using the ThermaTech superheated water system — and we’re proud to be the only company in South Australia offering this technology. ThermaTech gently removes dirt, paint, and grime without harsh chemicals or abrasion, making it ideal for sandstone, bluestone, and limestone.
For safe, effective, and environmentally responsible stone restoration, trust the experts with exclusive access to the best in modern conservation technology.
Built-up dirt or pollutants can accelerate the growth of biological matter, which in turn can quicken the erosion and decay of stone surfaces and mortars.
Unlike a conventional hot water pressure washer, the ThermaTech system combines continuous high
temperature and pressure and lower water volume. This is delivered as a liquid spray, even at
temperatures close to 155ºC. Low pressures can be used for the gentle cleaning of the most delicate substrates. The ThermaTech has approximately 50% more performance in terms of pressure, as well as in terms of water volume than other styles of systems.
Often without the addition of any chemicals, ThermaTech can be used for the melting or removal of the following from stone, brick, limestone, sandstone, granite and more:
YES! The ThermaTech system was developed in the UK and is, unlike other machines, purposely made for delicate, historic surfaces and substrates and has been used on structures from historic castles like the Tower of London to stone statues in Jeddah.
Yes! Energy consumption is minimised through high-efficiency electric motors and air powered devices. The highly effective cleaning delivered by the ThermaTech® system reduces reliance on cleaning chemicals by enabling effective use of milder chemicals (where required). Water consumption is key and the system has been designed around high performance in conjunction with reduced water consumption .
