Waterproof Click-Lock Flooring Planks with Composite Core

The patent applies composite materials by combining bamboo dust, wood dust, or cork dust with high-density polyethylene (HDPE) or polyvinylchloride (PVC) to create a core layer that resists moisture. This composite structure allows the flooring to maintain dimensional stability and prevent swelling and warping when exposed to moisture, while still achieving the desired appearance and comfort.

The patent changes the material parameters by using bamboo dust, wood dust, or cork dust combined with HDPE or PVC to create a core layer that provides moisture resistance at a lower cost than ceramic tile or stone. This composite material achieves the desired moisture resistance while being more economical in both materials and installation.

The patent uses a rigid core layer made of bamboo dust, wood dust, or cork dust combined with HDPE or PVC that acts as a stable base, preventing subfloor imperfections from transferring through. The rigidity of this composite core layer maintains adhesive strength and prevents curling damage, even in moisture-prone areas.

The patent incorporates moisture resistance directly into the core layer material composition during manufacturing, rather than applying waterproofing treatments afterward. The core layer is pre-formed with bamboo dust, wood dust, or cork dust combined with HDPE or PVC, providing inherent moisture resistance that eliminates the need for additional waterproofing steps during installation.
