Bentonite Pond Sealing & Natural Pond Repair in Devon

Bentonite Pond Sealing & Natural Pond Repair in Devon

Natural Solutions for Leaky Ponds Across Devon and the South West

If your pond struggles to hold water or dries out too quickly, the issue is often in the soil. Many older or newly built ponds across Devon, Dartmoor, and the South West sit on permeable ground that simply won’t retain water.

At Sasaquatics, we offer professional bentonite pond sealing and natural pond repair — a sustainable, chemical-free solution that restores ponds naturally and permanently.

What Is Bentonite Clay?

Bentonite is a natural volcanic clay that swells when wet, filling tiny gaps in the soil and forming a watertight seal. It’s completely natural, non-toxic, and safe for wildlife.

When properly installed, a bentonite-sealed pond can remain watertight for decades — without the need for plastic liners or concrete.

Why Choose Bentonite for Pond Sealing?

• 100% natural and eco-friendly

• Wildlife-safe – no plastic or chemical components

• Self-sealing – expands and reseals cracks over time

• Blends beautifully into the landscape

• Low-maintenance and long-lasting

This makes bentonite clay ideal for:

• Farm and estate ponds

• Natural swimming ponds

• Wildlife ponds and scrapes

• Rewilding and habitat creation projects

Our Professional Pond Sealing Process

Our team combines soil science, hydrology, and habitat design to ensure your pond is both watertight and ecologically healthy.

1. Site and Soil Assessment – We analyse the pond base and subsoil to understand water movement and clay content.

2. Preparation and Reshaping – The pond bed is cleared, graded, and compacted to create an even surface.

3. Bentonite Application – We calculate and apply the correct amount (typically 5–10 kg per m²), mixing it into the soil for an even, watertight layer.

4. Moisture and Compaction – Controlled compaction ensures the bentonite bonds fully with the soil.

5. Refilling and Planting – The pond is gradually refilled and re-planted with native vegetation for a thriving ecosystem.

The result? A natural, leak-free pond that looks and functions as part of the landscape — not a plastic insert.
