ENHANCED RAW EARTH MATERIAL FOR COMPRESSED EARTH BLOCKS CONSTRUCTION

Reducing the environmental footprint of building materials is a major challenge in the construction industry. This innovative process makes it possible to reinforce a wide range of excavated soils by making them suitable for raw earth construction. Compressed earth blocks possessing enhanced mechanical properties and water resistance are fabricated with addition of biopolymers. These clay materials, 100% geo-based and bio-based, are an ideal solution for building the city of tomorrow.

Applications

• Compressed earth blocks for eco-construction
• Rehabilitation of raw earth heritage
• Soil stabilization
• Load-bearing wall
• Thermal inertia wall
• Internal partition wall (acoustic performance and comfort)

Competitive advantages

• High mechanical strength (> 5 MPa compression strength)
• Improved water resistance
• 100% geo-based and bio-based building material
• Valorisation of a wide range of excavated soils
• Valorisation of industrial by-products, source of biopolymers
• Minimal environmental footprint
• Moisture regulation in buildings for better comfort
