How long does it last?

We've been testing and improving our products since 2008. When properly applied the Waterproof Membrane will extend the life of your Pond by 10+ year.

Why do i need the GEO Textile?

The GEO Textile is sandwiched with the Waterproof Sealant over cracks, holes, seams, vents etc. It is used for reinforcement and stabilisation purposes.

What is the Seam Tape for?

The Seam Tape is used to cover bigger holes and cracks as it is firmer than the GEO Textile. Like the GEO Textile, it is used for reinforcement and stabilisation purposes.

Why do I need the Quick Dry Spray?

The Quick Dry Spray is optional. However, we recommend spraying it on top of a wet Waterproof Sealant layer for a quicker cure and to protect it from moisture.
