Elbe – Geotextile Underlay Polyester White 300 g/m² 50 m × 1.50 m

At 300 g/m², this 50 m × 1.50 m polyester geotextile roll from Elbe — one of the world’s leading pool liner specialists — delivers a full 75 m² of heavy-duty protective underlayment from a single roll. The 1.5 mm-thick white fabric sits between the pool substrate and the liner, acting as a buffer layer that guards against punctures, abrasion, and ground movement across in-ground and above-ground installations alike.

Liner protection & substrate cushioning

Pool liners are vulnerable wherever the substrate contains stones, compacted gravel, roots, or rough concrete. This 300 g/m² geotextile creates a resilient intermediate layer that absorbs point loads and distributes pressure evenly, reducing the risk of punctures or stress tears in the liner over time. It also stabilises the ground immediately beneath the liner, limiting the pocket formation that can occur when soil shifts under the weight of water.

Cutting & installation flexibility

Supplied as a continuous 50-metre roll, the fabric can be trimmed with standard scissors or a utility knife to match any pool shape — rectangular, oval, kidney, or freeform. Strips are simply overlapped at the seams rather than joined with adhesive, making on-site installation straightforward for professional installers and experienced self-builders. The 1.50 m roll width suits common pool bench widths and can be double-layered on the floor for additional protection on particularly rough substrates.

Material quality & Elbe credentials

Elbe has manufactured flexible pool surface products since 1956 and is one of the most established liner brands in Europe, with products installed across more than 60 countries. The white polyester construction is resistant to biological degradation, pool chemicals, and temperature fluctuation — properties that ensure the underlayment retains its protective function for the full working life of the liner it supports.
