Since then we've sold over two million tubes, enough to successfully treat over 6.5 million meters of 9-inch wall. Dryzone has been used in high profile settings such as lords cricket ground pavilion and the Royal college of music, London. proven performance dry zone has been independently tested and approved by the bba as well as multiple equivalent organisation internationally, making it the most rigorously tested DC injection cream on the market. By using Dryzone to treat rising damp you can be sure that you only have to do the job once. effective formulation the specially formulated damp course injection cream is developed for maximum spread throughout the mortar to form a new damp course. It has been shown to be effective on a wide range of substrates and in a wide range of conditions. coverage based on a standard 9-inch wall, each 600ml cartridge of Dry zone will cover up to 3.3 linear meters. At Safeguard Europe we also manufacture 5L tubs, ideal for larger jobs and 310ml tubes, which come with applicator nozzles so that all you require is a standard Mastic gun.
