Evolving void tubes [QPF series] alternative to paper void tubes for fence foundations, etc.

Invented a completely new evolving void pipe as a replacement for paper void pipes used in fence and guardrail foundations, using the NETIS void wrap method!

I am offering a patent license for a void pipe that has never been seen before! We are looking for a company that can utilize the manufacturing and sales rights related to this patent (limited to one company)! Traditionally, "paper voids" have been common for void pipes, which were discarded after use and considered disposable. However, the industry must strive to "reduce waste," and the "effort required for processing and removal of paper void pipes" has been a challenge. The evolved void pipe solves these issues! The main objective of this invention is to place an outer skin material (sheet material) around the void pipe, and in the opening formation tool where concrete is poured around this outer skin material, it allows for easy removal of the void pipe from the outer skin material after the concrete has hardened, thereby achieving waste reduction. 【Product Features】 - Use of resin sheet material - Ability to remove the void pipe from the sheet material after the concrete has hardened - Reusability of the sheet material and void pipe *For more details, please contact us.
