Hydrated lime
High-purity alkalinity in a safe, ready-to-use dry powder. Chemically known as calcium hydroxide (Ca(OH)₂), hydrated lime is a dry, easy-to-handle white powder that has already completed the exothermic slaking process at the manufacturing facility, making it significantly safer to handle on-site than quicklime. In asphalt mixes, it acts as a powerful anti-stripping agent, protecting pavements from moisture-induced damage, reducing rutting and extending road service life.
Industries & applications
Where it's used
Asphalt
Adding hydrated lime to asphalt mixes significantly improves pavement durability. It acts as a powerful anti-stripping agent, protecting roads from moisture-induced damage, reducing rutting, and ultimately extending the lifespan of the road network.

Other Construction & Infrastructure products
Graded Aggregate limestone
The precision-sized foundation for superior structural integrity. Engineered for exact dimensional consistency, Graded Aggregate Limestone delivers the robust physical backbone required for heavy-duty civil engineering, providing predictable, uniform performance that minimises material voids. As a construction aggregate, its precise gradation delivers a high-strength, reliable base material for concrete, brick manufacturing and general civil works.
Milled Unslaked
The high-surface-area powerhouse for rapid, uniform chemical reactivity. Processed into a highly refined powder, Milled Unslaked Lime maximises exposed surface area to deliver immediate and exceptionally efficient chemical integration, engineered for systems that demand accelerated slaking rates and aggressive, uniform pH adjustment. In Autoclaved Aerated Concrete (AAC), it serves as a primary reactant, driving the chemical process that creates the material's cellular structure — producing lightweight, insulating, fire-resistant blocks.
KB 15
A medium-particle, high-brightness calcium carbonate extender that improves opacity, durability, and cost efficiency in decorative paints, textured coatings, adhesives, sealants, and construction products.
