Yes. Our planter box factory offers liners specifically designed to protect wood from soil moisture. We treat liners as an important part of a long-lasting wooden planter, not as an afterthought. Depending on the planter style, climate, and planting plan, we can supply a factory-installed liner, a cut-to-size liner kit, or a custom-engineered moisture barrier.
The liner creates a reliable separation between wet potting soil and the wood. Without this barrier, constant moisture can soak into the grain, soften fibers, encourage mold, cause warping, and speed up rot. A properly selected liner also reduces staining from tannins and fertilizers, helps keep the planter structure stable, and can extend the service life of cedar, pine, teak, acacia, or thermally treated wood.
We offer several liner materials. High-density polyethylene, or HDPE, is a popular choice for waterproof protection. It is flexible, puncture-resistant, and easy to clean, and it can be heat-welded or folded into corners. EPDM rubber offers excellent flexibility and durability in cold or hot climates. For projects that need moisture control without a fully sealed membrane, non-woven geotextile can be used as a drainage and separation layer. In some designs, we combine a waterproof HDPE liner on the sides with a geotextile-wrapped drainage zone at the bottom, so excess water can move away while wet soil stays away from the wood.
Drainage is just as important as waterproofing. A liner that traps water can create its own problems. That is why our planter liners can be made with drainage holes, overflow outlets, raised false bottoms, or gravel-bed details. We plan the liner around the planter's drainage strategy, not against it. For self-watering or reservoir planters, we can also integrate separate water compartments and wicking systems.
Because every planter box is different, our liners are custom-made. We work from your internal dimensions, corner style, drainage layout, and planting requirements. Common options include straight-sided liners, folded-corner liners, formed trays, stapled-in liners, removable liners, and liners with hidden drainage channels. We can pre-drill holes, reinforce stress points, add filter fabric, or leave the liner ready for on-site installation. If you are a retailer, landscaper, builder, or garden brand, we can also produce private-label liner kits with instructions and branded packaging.
For wood protection, material thickness matters. A liner that is too thin can tear during soil loading or later maintenance. A liner that is too rigid may crack at corners. Our team recommends the right gauge and shape based on planter size, soil volume, exposure, and expected lifespan. We can provide samples so you can test flexibility, fit, and drainage before mass production.
Installation is straightforward. In most factory-installed planter boxes, the liner is placed before the drainage layer and soil. We seal or fold corners carefully, keep the top edge above the soil line where possible, and make sure drainage paths remain clear. For DIY kits, we supply cut pieces, corner folds, and simple instructions. Routine care includes checking drainage holes, removing standing water, and replacing damaged sections if needed.
So the direct answer is yes: our planter box factory does offer liners to protect wood from soil moisture. We can supply basic moisture barriers or fully customized liner systems for residential, commercial, and wholesale projects. Tell us your planter dimensions, wood type, drainage plan, and target market, and we will recommend a liner that protects the wood, supports healthy plants, and fits your production budget.
