Durable and beautiful though it is, over time simple rainwater can visibly decay and stain unprotected concrete, brick and stone cleaning surfaces.
When rainwater soaks into the masonry it dissolves natural salts that recrystallise when the surfaces dries.
The salts build up in the pores from repeated wet/dry cycles. In cold weather water freezes and expands inside causing cracks to appear, at first the cracks and fractures are microscopic however they do not stay that way.
All of our surface protection products and services are supplied by Tensid UK and applied by our expert stone and masonry technicians.
