Cements and additives are essential for a wide range of building, landscaping, and repair projects. From laying foundations to fixing patio slabs, the right product ensures strength, stability, and long-lasting results. Popular choices like Blue Circle Concrete and ready mixed concrete are perfect for everything from paths to shed bases, offering easy application and consistent performance. For bricklaying and general masonry work, Volden Mortar and ready mixed mortar come in various shades including grey mortar and white mortar, making it easy to match or contrast with existing structures. Smaller tasks are made even easier with 5kg mortar packs—ideal for DIYers tackling patch repairs or repointing.
When it comes to patios, both grey patio grout and ready mixed patio grout are excellent for securing paving slabs and preventing weed growth. For specialist jobs, fire cement provides heat-resistant sealing around stoves and flues, while postcrete offers quick, no-mix installation for fence posts.
