Sodium Bentonite Clay Granules 100kg (5 x 20kg) | Eco-Friendly Pond Sealer and Lake Sealer | Plastic-Free Alternative For Ponds, Lakes & Reservoirs | UK Supplier

• Eco-Friendly Alternative to Traditional Pond Liners: Sodium Bentonite is a highly effective, plastic-free alternative to traditional pond liners that does not damage the surrounding ecosystem. It expands when wet, forming an impermeable clay barrier against water — and unlike rubber or HDPE liners, it maintains plasticity and never becomes brittle over time.
• Easy Application for Any Project Size: The bentonite clay granules can be applied by hand or farm machinery, making them suitable for everything from small garden ponds to large lakes, reservoirs and dams. No specialist equipment or professional installation required.
• Durable and Puncture-Resistant: No risk of punctures in the lining by farm animals or wildlife, ensuring long-lasting protection and reliability for your pond or water feature
• Long-Term Solution That Never Wears Out: Once applied, sodium bentonite clay forms a permanent seal that self-repairs minor leaks over time — simply sprinkle additional granules over the affected area. Available in quantities from a single 20kg bag up to 1 tonne bags to suit any project scale.
