Building materials

Boost productivity into every batch. Our hydrated lime solutions deliver smooth application, excellent workability, and extended pot life. This gives teams flexibility on site, reducing waste, and ensuring uniform finishes across facades and masonry. 

Where this helps:

• Masonry mortars that are easier to apply and work with 
• Renders and plasters with consistent, high-quality appearance 

Our products also enable mortars, renders and plasters to absorb structural movements, improving long-term performance and protection.

Quicklime is a key ingredient in AAC, a lightweight material known for excellent fire resistance and thermal insulation. We manufacture premium quicklime with tailored reactivity curves to match the characteristics of your raw materials. By customizing our solutions to your proprietary formulations and processes, we help ensure consistent product properties and optimal final performance.

For calcium silicate (sand-lime) brick production, we supply high-quality quicklime engineered to meet your performance requirements. In autoclaved processes, where lime reacts with quartz sand to develop strength and load-bearing capacity, consistent reactivity is critical. We provide quicklime with customized reactivity curves tailored to your raw materials and production parameters - helping you achieve uniform brick quality, reliable strength development and stable performance.

In clay brick and roofing tile production, limestone is incorporated into clay bodies to control firing behavior and oxidation in the kiln - supporting consistent color development and surface appearance. By stabilizing these parameters, it helps you achieve repeatable visual performance and uniform results across production runs.

In modern concrete design, milled limestone supports optimized mix performance. It enhances workability, improves particle packing, reduces porosity and contributes to both early-age strength and long-term durability. By lowering the heat of hydration, it helps you manage thermal control in mass concrete applications where temperature stability is critical. When used to partially replace clinker in cement, limestone also helps you reduce CO₂ emissions and advance more sustainable construction practices.

In fiber cement siding, cladding and backer boards, limestone serves as a non-abrasive filler that enhances stiffness and mechanical strength. Its properties also help you reduce silica dust during fabrication and installation - supporting safer handling and more controlled production conditions.

For restoration projects, hydrated lime provides the durability and long-term resistance to ageing required to preserve historic structures. Its performance has been proven over centuries in heritage buildings worldwide - including landmark constructions such as the Great Wall of China.

In asphalt shingle production, limestone fillers enhance mechanical strength and help you maintain stable viscosity through controlled particle size distribution. The high-calcium chemistry contributes to achieving the tear strength required for reliable roofing performance. For more than 50 years, our fillers have supported consistent results in roofing applications - including patented headlap granule solutions that deliver strong bonding and reliable opacity.
