PCiS contracted Epicuro to apply HBG after the granite structures had been cleaned, to protect them against further seawater related damage, including aggressive freeze-thaw attack. HBG penetrates the surface's capillaries to form an invisible, yet breathable, protective barrier that repels water, graffiti and other surface contaminants, ensuring facades remains dry, clean and protected at all times. HBG has a 15 year performance guarantee so this will considerably increase the intervals between essential maintenance, reducing on-going operating costs.
HBG proved to be the ideal solution for the swing bridge, preventing rain water from soaking into the masonry and keeping it dry and clean. Whilst cleaning the stonework, a substantial amount of moss and algae which had accumulated over the years was revealed, due to the damp and dark conditions underneath the main structure. By controlling the water supply to the granite masonry surface, HBG provided an excellent solution to limiting reoccurrences of moss and algae.
