PVC Waterproofing Sheet 2x50, 4x25, 6x25 and 8x20 m – Geomembrane for Ponds and Construction Storage Tanks

Frequently asked questions

• What is this waterproofing membrane and what is it for?

  It's a PVC geomembrane designed to waterproof ponds, built-in tanks and irrigation reservoirs. It holds the water in without needing a rigid lining, so you save on construction work and cost. It's the usual solution when you want a large, custom-made water reserve.

• How is it installed?

  It's laid directly over the excavation or the finished construction, covering the basin. Being a flexible membrane, it adapts to the shape of the pond or tank without needing rigid parts. It's a simple installation compared to lining the basin.

• What roll sizes are available?

  There are four sizes by width and length: 2 x 50 m and 4 x 25 m, both 100 m²; 6 x 25 m, at 150 m²; and 8 x 20 m, at 160 m². The choice depends both on the total surface area you need and on the width that best suits covering the basin.

• How do I know which size is right for me?

  Measure the length, width and depth of your pond and check which roll width covers it best, because the total surface area isn't the only thing that matters. Between 2 x 50 m and 4 x 25 m, you get the same 100 m², but laid out very differently. If you're unsure, write to us Monday to Friday from 10:00 to 19:00 and we'll look at it with you.

• How is a roll of this size shipped?

  It's a very heavy product, between 65 and 104 kg depending on the size, so it doesn't travel by standard courier: it's shipped by pallet freight and may require a specific delivery time and cost. Get in touch before buying if you have any doubts about delivery or access to the unloading point.

• Is it only for irrigation ponds?

  Its main use is for ponds, built-in tanks and irrigation reservoirs. In all these cases it does the same job: creating a flexible barrier that holds the water in while adapting to the shape of the basin. It's a very versatile solution for any built water reserve.
