Sample condition:

Intact

Site-driven material

This project reuses soil extracted from Tseung Kwan O Area 137 Fill Bank, aiming to explore the reuse approaches of soil components in construction waste. The bricks are made from soil extracted at two different locations. The soil was sieved, compressed and coated. The three coatings tested are concrete surface harder, acrylic-based wood oil, and glutinous rice flour paste. The results show the potential of soil-based bricks as a low-emission construction material.
