1. Waterproofing Materials
Calcium bentonite is a natural material used in waterproof coatings, membranes, grouts, and self-healing waterproof systems. When hydrated, it swells and forms a dense barrier that helps block water penetration. It can fill small cracks, gaps, and irregular surfaces, making it suitable for basements, foundations, tunnels, roofs, and underground structures.

2. Foundation Improvement
In foundation improvement, calcium bentonite helps stabilize weak or loose soils by reducing porosity, improving cohesion, and increasing compaction performance. It supports better bearing capacity, reduces water infiltration, and helps prevent soil softening, erosion, and uneven settlement in buildings, roads, bridges, and underground projects.

3. Coatings & Putties
In coatings and putties, calcium bentonite works as a natural thickener, anti-settling agent, and suspending aid. It helps improve viscosity, storage stability, adhesion, sag resistance, and application smoothness. It also supports water retention and reduces shrinkage, helping create a more durable and even finish for wall putties, decorative coatings, and industrial paints

Sealing & Anti-Seepage Performance: Controlled swelling capacity (10–15x water absorption) and low hydraulic conductivity (≤1×10⁻⁹ cm/s) to form dense, impermeable barriers; optimized particle size distribution (200–400 mesh) for uniform compaction, ensuring effective waterproofing in liners, foundations, and underground structures.

Stability & Compatibility: High mechanical strength and resistance to chemical erosion (acids, alkalis, salts) and temperature fluctuations; good adhesion to concrete, soil, and geosynthetics; low shrinkage/expansion rates to maintain structural integrity in long-term service.

Workability & Functional Tuning: Adjustable plasticity and rheological properties for easy mixing, shaping, and construction; tailored montmorillonite content (≥80%) to enhance binding force and load-bearing capacity; non-toxic, eco-friendly composition compliant with construction environmental standards, suitable for waterproof coatings, grouts, and soil stabilization.
