Stirling Lloyd, the market leaders in waterproofing and protective coating technology have supplied a package of products, which have helped ensure the successful redevelopment of a historical building in North Wales.

Built in 1860, St Clare's of Pantasaph, near Holywell is a former convent and listed building, which has been restored and transformed into a picturesque residential development consisting of apartments and townhouses.

Developer's David McLean Homes approached Stirling Lloyd in their search for a waterproofing and paving system suitable for application to the development's main terrace, which sits directly above a number of private garages. They required a waterproofing system which would be 100% effective, preventing any leakage into the area beneath with a strong bond to the substrate to help ensure a long service life. The paving system needed to be hard-wearing, aesthetic and suitable for pedestrian traffic.

Stirling Lloyd suggested using a combination of high performance products, namely the Integritank® structural waterproofing membrane and the Dreen® paving system. Integritank® is a BBA certificated, seamless, spray-applied system, based on methyl methacrylate (MMA) resins, which cures rapidly to form a remarkably tough waterproof membrane.

Dreen® is a high quality paving system specially developed for pedestrian accessed flat roofs, balconies and terraces. Lightweight yet durable, the system incorporates drainage slots to eliminate standing water and is available in a range of decorative finishes and thicknesses. The system is fully demountable and restorable, allowing easy access for maintenance and inspection of the waterproofing and drainage system, a feature that is highly beneficial for clients.
