DeepStream Designs Custom Welded Liners
Tournesol Thermoformed ABS Plastic Liners
NOTE: If you're building custom planters that require liners, keep in mind that our stock liners are the least expensive option, followed by thermoplastic liners that are molded to order, then custom-welded liners. If you have some flexibility on size, find out what size liners are available BEFORE you build the planter box. It is much easier and less expensive to build a custom planter box to fit existing liners than to find liners that will fit your custom planter box!
If your planters will not be dug up and replanted every year then we strongly recommend adding Drain Filter Packs for each drain. A three-part filter combines the waffled plastic backing of TREMdrain, three layers of filter fabric, and Biobarrier buttons to inhibit root growth. They may not stop aggressive root systems like Bamboo and Clusia.
Filter packs, when used in conjunction with clean 1-2 mm inorganic drainage material to slow the flow of the water to the drain, could prevent clogged drains for a decade or more.
