Frequently Asked Questions (FAQ)

To assist landscape architects, project managers, and procurement specialists in their planning, we have compiled detailed answers to the most common technical inquiries regarding our natural stone products.

• What is the recommended installation depth for the 15-30mm size range?
  For pedestrian pathways, we recommend a compacted depth of 40-50mm. This depth ensures complete ground coverage and structural stability, preventing the underlying soil or weed membrane from becoming exposed, while avoiding the sinking sensation that occurs if the aggregate layer is laid too deep.

• How does the <3% water absorption rate benefit freezing climates?
  A low porosity rate means the stones absorb virtually no moisture. In freezing conditions, trapped water expands and causes inferior rocks to crack and shatter. Our stones easily survive over 400 freeze-thaw cycles without structural degradation, drastically reducing spring maintenance and replacement costs.

• Are these stones suitable for direct contact with aquatic life in ponds?
  Yes. Because they are 100% natural and untreated with any artificial sealants, dyes, or chemicals, they are completely inert. They will not alter the pH balance of the water or leach toxins, making them perfectly safe for koi ponds and ecological water features.

• How do we maintain the visual appearance of the stones in high-traffic commercial areas?
  Maintenance is highly efficient. The natural smooth surface resists dirt adhesion. Routine maintenance simply requires occasional leaf blowing to remove organic debris, and a light pressure wash using a wide-angle nozzle once a season to restore their original luster.

• Can this material help in achieving green building certifications?
  Absolutely. The exceptionally low carbon footprint (<0.15 tonnes CO&₂e per tonne), combined with its highly permeable nature that supports sustainable urban drainage systems (SUDS), makes it an ideal material for projects aiming for LEED or similar ecological building standards.

• What is the best way to contain the pebbles to prevent spreading into adjacent lawns?
  We highly recommend installing rigid edging materials—such as steel, aluminum, or treated timber borders—prior to laying the stones. The edging should sit approximately 10-15mm above the final pebble level to securely contain the 15-30mm aggregates under heavy foot traffic.
