PVC Waterproofing White 4 x 25 m. is a versatile sheet for indoor cultivation that protects the floor against spills, facilitates cleaning, and improves light reflection. Wide roll to cover entire rooms and create a continuous barrier against moisture, liquids, and crawling pests.
THIS PRODUCT IS SUPPLIED ON REQUEST

The White Waterproofing PVC 4 x 25 m. sheet is made of high-strength polyvinyl chloride with a thickness of 0.5 mm, balancing flexibility and durability for intensive use.
The white color increases diffuse reflection, providing uniform light around cannabis plants and helping to reduce shadows under tables, benches, or pots.
The 4 meters wide by 25 meters long format speeds up installation on large surfaces, minimizing overlaps and weak points.
It acts as a waterproof barrier against nutrient solutions, water, and biostimulants; prevents leaks to the slab, parquet, or cement, and allows intensive watering without compromising the room.
The smooth finish makes it easy to remove runoff with a squeegee or wet vacuum and allows periodic disinfection with horticulture-safe solutions, ensuring a hygienic environment in indoor cultivation facilities.
In addition, it helps limit the entry of crawling insects from joints and baseboards by acting as a continuous sealed skin. Logistics note: this item may incur additional shipping charges in the cart due to volume and weight.

In cannabis cultivation rooms with frequent watering, the White Waterproofing PVC 4 x 25 m. sheet acts as a continuous "tray" that collects spills and protects technical floors. The white tone increases reflected light and helps homogenize PPFD at edges and aisles. Ideal for large tents, dedicated rooms, service corridors, and mixing areas where cleanliness and safety are essential.
It is used to waterproof floors, contain spills, facilitate cleaning, and improve reflection in indoor cultivation. It reduces the risk of stains, dampness, and floor deterioration; limits pathogen hotspots by allowing quick disinfection; provides a barrier against crawling insects and stabilizes the work environment when significant volumes of water are used.
Optimal performance in combination with butyl tapes or premium duct tape to seal overlaps, PVC baseboards for a clean perimeter, finishing profiles, and cultivation trays that concentrate drainage. Adding non-slip mats in walkways, dehumidifiers, and oscillating fans helps control VPD. EC/pH meters and liquid extraction pumps complete an efficient set. All available at Hydroponics Blanes with a catalog of indoor accessories and discreet shipping.
1) Cleaning and leveling: sweep, vacuum, and remove sharp particles. 2) Cutting and placement: unroll the 4 x 25 m roll, cut to size with a cutter and metal ruler, leaving a margin of 5–10 cm to overlap walls or baseboards. 3) Joint sealing: overlap 5–8 cm between sheets and apply butyl tape or compatible sealant. 4) Perimeter finishing: fix to the baseboard with strong double-sided tape or profiles, creating a watertight "bathtub". 5) Protection of critical points: reinforce under tanks, pumps, or work tables with a second layer or rigid plates. 6) Maintenance: remove runoff after each watering, use a mop/wet vacuum, and disinfect weekly with a horticulture-safe solution. 7) Inspection: check cuts and corners; replace seals if necessary to maintain watertightness.
