Proviacal® DD
Proviacal® DD, is a high-performance lime-based solution tailored for hydraulic structures. Designed to valorize local soils and enhance structural resilience, Proviacal® DD offers a sustainable alternative to traditional construction methods, delivering both technical and environmental benefits.
Proviacal® DD acts directly on the intrinsic properties of treated soils, delivering immediate and long-term improvements in bearing capacity, stability, and erosion resistance.
Technical information
Certification
Proviacal® DD classifies as CL 90-Q according to EN 459-1:2015, with CaO available ≥ 88%
Functional performances
Improved workability:
• Reduces soil moisture by approximately 1% per 1% of product added and up to 5% under optimal conditions (wind and thorough mixing).
• Lowers soil plasticity, enhances compaction, and significantly increases bearing capacity, enabling safe site access and traffic.
Enhanced stability:
• Boosts mechanical strength and long-term resistance to water and frost.
• Minimizes swelling and shrinkage, while increasing soil cohesion for lasting structural integrity.
Superior erosion resistance:
• Raises critical shear stress thresholds, erosion occurs only under significantly higher loads.
• Slows erosion progression and reduces vulnerability to animal burrowing, extending the lifespan of treated structures.
Reliable watertightness
• Maintains permeability levels comparable to native soils, ensuring effective hydraulic performance, and favorably improves water insensitivity.
