Buytl Liners

Build a lifetime foundation for your koi pond, formal water garden, or architectural feature with our range of premium butyl pond liners and heavy-duty synthetic rubber membranes. Regarded across the aquatic industry as the premier choice for flexible pond lining, genuine butyl rubber provides exceptional durability, puncture resistance, and all-weather flexibility to keep your pond securely watertight for decades.

Manufactured from high-grade, non-toxic synthetic rubber polymers, our butyl liners are 100% fish-safe and plant-friendly, creating a stable, chemical-free environment for prized koi and aquatic life. The ultra-supple, elastic membrane drapes effortlessly into deep excavations, conforming smoothly around bottom drain sumps, steep side walls, and contoured planting ledges without excessive creasing or tension. Highly resistant to UV degradation, ozone, soil acids, and extreme frost down to sub-zero temperatures, butyl will not dry out, split, or become brittle over time. It bonds reliably with pond sealants and clamping flanges on bottom drains and skimmers, ensuring permanent, leak-proof transitions throughout your build. When installed over a protective geotextile underlay, it forms an impenetrable barrier against sharp stones and aggressive root systems.

Available in standard 0.75mm and extra-tough 1.0mm thicknesses across a wide selection of pre-cut dimensions and bespoke roll sizes, explore our complete butyl liners collection to find professional-grade rubber membranes engineered for permanent, dependable water containment.
