What is this type of hydraulic lime mortar used for?
• Granite, basalt, flint, engineering brick • Marine building and construction • Bridges, canals, dams, harbours, marinas • Repointing and building by the sea, river, canal • Retaining walls • Brick, stone and block paving • Coping stones, cornice, plinths, balustrades • External renders in severely exposed areas Alternatively Are you are working with very soft, crumbing or chalky masonry, building internal walls or applying an internal render?

NHL 5 is the hardest, fastest setting mix of hydraulic lime mortar. This material is best for durable, dense and impermeable building materials such as granite, basalt, flint and engineering brick. Its high degree of hydraulicity (ability to set underwater) means this mortar is suitable for building in marine environments such as harbours, river sid
