Lithica™ is TechStone's premium resin-bonded natural stone aggregate coating system — engineered for architects, property developers, and commercial construction projects across the Philippines. Available as Lithica Floor and Lithica Wall, the system creates a seamless, durable stone-aggregate surface on concrete, masonry, and rendered substrates in 32 curated colour blends.
TechStone Exposed Aggregate delivers the timeless visual richness of natural stone aggregate surfaces through a precision-engineered resin-bound system that outperforms traditional loose-aggregate and honed-concrete approaches in both durability and design flexibility.
Natural stone aggregates -- selected for colour, grain size, and mineral character -- are bound in a high-performance resin matrix to create a fully permeable, slip-resistant surface with genuine material authenticity. Unlike poured-in-place exposed aggregate concrete, the resin-bound system produces a smooth, level surface without loose stones, trip hazards, or the drainage issues associated with impermeable hardscape.
The system is specified by landscape architects, developers, and contractors for residential driveways, commercial forecourts, pool surrounds, garden paths, and public realm hardscape where the visual warmth of natural aggregate is required alongside the engineering performance of a modern surface system. Available in a broad palette of aggregate blends -- from warm sandstone tones to cool granite grays -- each installation is colour-matched to the project design intent.
Permeable by design, the system supports sustainable urban drainage (SuDS) requirements, allowing rainwater to pass through the surface matrix into the sub-base rather than contributing to surface runoff. UV-stable resin formulations ensure colour retention and structural integrity under sustained tropical and subtropical exposure conditions.
