Pond Liners & Underlayment

The waterproof foundation your pond depends on.

A pond is only as good as its liner, and the right underlayment makes sure it lasts for years. We carry commercial-grade pond liners in durable, trusted materials designed to keep water in and weeds out.

Paired with our heavy-duty underlayment fabric, these liners protect against rocks, roots, and punctures, ensuring your pond or water feature stays leak-free and low-maintenance. They're perfect for koi ponds, garden ponds, and custom water features of all sizes.

Our experts help you calculate liner sizes, explain installation best practices, and get everything you need delivered in bulk or rolls.

Don’t let leaks ruin your hard work. Start with the right liner and build from there.
