Drainage paving allows water to be properly discharged, preventing standing water and structural damage. From the earliest design stages, it is essential to choose materials with documented performance that improve water management and the durability of outdoor areas, avoiding impermeable surfaces such as asphalt and concrete, or unstable ones such as interlocking pavers and loose gravel. **Prima Drain Stone®** is a seamless drainage paving made with natural stone aggregates. When laid on pervious concrete, it allows stormwater to infiltrate into the ground. It is composed mainly of aggregates sourced from stone-processing waste, in a range of grain sizes and colours, bound with a low-VOC two-component resin, and ensures long-term stability. Documentation from the aggregate supplier and technical data sheets for the binder are available on request.

The binder is a solvent-free, low-VOC two-component resin. The natural stone used, including marble, granite, porphyry and quartz, comes mainly from stone-processing waste. We use products from selected manufacturers, with technical data sheets and environmental documentation available on request. When laid on pervious concrete, Prima Drain Stone® can contribute to the building’s LEED credits for Rainwater Management and Heat Island Reduction. On request, we provide documentation to support verification against Italy’s Minimum Environmental Criteria for construction (CAM, Ministerial Decree of 23 June 2022), in particular the criteria on site permeability and reduction of the urban heat island effect.
