PVC Waterproofing Sheet 6 x 25 m. offers a watertight, flexible, and resistant barrier to isolate water and moisture in grow rooms. The wide black roll allows you to cover large areas with few joints, making cleaning, organization, and safety easier in indoor cultivation.

This waterproofing sheet made of polyvinyl chloride (PVC) with a 0.5 mm thickness is designed for demanding jobs in environments with frequent irrigation. The black color limits unwanted reflections under LED or HPS lights, creating a stable and professional environment.
The 6 x 25 meter format covers large surfaces with fewer overlaps, reducing leakage points and saving installation time.
The material can be cut with a utility knife or scissors, adapts to corners, and easily lines trays, tables, and tanks.
A robust and economical option for projects seeking drainage containment, floor protection, and the creation of nutrient mixing areas.
Ideal for those who want to set up an organized self-cultivation or install a scalable indoor grow, with recurring irrigation, transplant, and cleaning processes.
Water control makes the difference in indoor growing. PVC Waterproofing Sheet 6 x 25 m. creates a waterproof base between pots, tables, and flooring, preventing leaks to lower floors or neighboring rooms. In projects with cannabis plants, where drainage is continuous, the sheet helps maintain a hygienic environment, prevent mold, and protect nearby structures. The 6 m width provides uniform coverage in large rooms, work corridors, and nutrient solution preparation areas.
PVC Waterproofing Sheet 6 x 25 m. is used to contain drainage from pots, line water tanks, insulate surfaces exposed to fertilizer spills, and channel runoff to collection points. The 0.5 mm thickness provides resistance to traffic, tray scuffs, and pot movements. The flexibility of PVC offers a precise fit in corners, while the black finish helps control light reflections. Daily cleaning is simple: a squeegee or cloth removes water and nutrient residues in seconds, supporting efficient maintenance routines.
In medium and large grow rooms, the 6-meter wide format minimizes joints and simplifies watertight assemblies. The sheet allows zoning of areas (irrigation, transplant, mixing, quarantine) and limits the spread of moisture or unexpected spills. Combined with drainage trays, collectors, or RDWC systems, it protects pumps, filters, and controllers from residual water. It fits in conditioned rooms and large cabinets, providing a uniform base for shelves, tables, and technical corridors. A consistent choice for productivity- and prevention-oriented projects.
