Desalination of Masonry Using Captive Head Washing

Crystallisation of salts is a major cause of damage to heritage and stone structures. Our BlueVac Captive Head Washing System is proven to reduce the salt content in masonry to a depth of up to 150mm.

With its captive head technology, a water wash dissolves and draws out salt from your surface while the captive head captures the waste - a desalination process pioneered by Let’s Clean.

Unlike the traditional desalination poultice method, the process is much quicker and results are instantly measurable - with no mess and no increase to the water load in the substrate.

With a portable conductivity meter, you can read the salt content of the captured water immediately and there is no obstruction to other works on the surface or work site.

Results are comparable, if not better, to a poultice application for desalination.
