{"title":"Masonry Mortar","description":"\u003cp\u003eMasonry mortar is the binder that unites bricks, blocks, and stone elements into a cohesive structure. Choosing the right mortar is not just a matter of strength: the mortar’s flexibility, vapor permeability, and chemical compatibility with the masonry units determine whether the building can move without the masonry cracking.\u003c\/p\u003e\n\u003ch3\u003eWhat types of masonry mortar are there?\u003c\/h3\u003e\n\u003cp\u003eCement-based mortar: For modern brick, concrete block, and structural masonry. High strength, fast setting. Strength classes are indicated by M5, M10, M15, M20 — the class defines the minimum compressive strength.\u003c\/p\u003e\n\u003cp\u003eLime-cement mortar: Lower strength, more flexible, and more vapor-permeable than pure cement. Used for repairing old brick masonry where the mortar strength must match the strength of the masonry units.\u003c\/p\u003e\n\u003cp\u003eNHL (natural hydraulic lime) mortar: Binder for historic buildings, heritage brick, and stone masonry. WTA-compatible, breathable, vapor-permeable, and compatible with old, soft bricks. Where cement-based mortar would crack soft bricks, NHL mortar is suitable.\u003c\/p\u003e\n\u003ch3\u003eThin-bed mortar for aerated concrete blocks\u003c\/h3\u003e\n\u003cp\u003eSpecial thin-bed mortar is required for aerated concrete (AAC) blocks: layer thickness is 1–3 mm, with fine grain size. The thin joint layer reduces the risk of thermal bridging and improves the thermal insulation performance of the masonry.\u003c\/p\u003e\n\u003ch3\u003eWhy can’t just any mortar be used?\u003c\/h3\u003e\n\u003cp\u003eStronger is not always better. In hard cement-based mortar, the masonry unit is the weakest element — due to movement and thermal expansion, the brick cracks, not the joint. With mortar of appropriate strength, the stress concentrates in the joint, where it can be repaired, not in the brick, where it cannot.\u003c\/p\u003e\n\u003cp\u003eBrowse our masonry mortars or request advice to select the mortar suitable for your masonry units and building type.\u003c\/p\u003e","products":[{"product_id":"kerakoll-biocalce-muratura","title":"Kerakoll Biocalce Muratura","description":"\u003cp\u003eCertified, eco-compatible, made from NHL 3.5 natural pure lime, compliant with EN 459-1 standard, for extremely breathable bedding and rubble filling of natural mortar masonry, ideal for GreenBuilding and monument restoration.\u003c\/p\u003e\n\u003cp\u003eContains only naturally sourced raw materials and recycled minerals.
