Water-curable block joint filler composition

Water-curable joint filler composition formulated with plantain extract binder and elastic particles

This technology is a block joint filler composition that cures with water, formulated by combining silica sand with a binder made of plantain extract, water glass, and sodium carbonate, along with fluorinated wax, beads, and rubber-based components.

Existing block joint fillers are prone to cracking after installation or lack sufficient elasticity, creating a need for a filler that is easy to cure with water while offering durability and flexibility.

By combining silica sand with a natural binder, elastic beads, and rubber-based components to enable water-curing, this technology can be applied to block paving joints to reduce cracking and enhance durability.
