A reputable manufacturer or fabricator will be able to provide detailed ASTM testing data and advice based on real-world experience for your project, rather than just a sales pitch. If a seller can't explain the difference between unreinforced rubber and reinforced polyethylene, or if they can't tell you the grab tensile strength of their material, they're likely just a reseller of generic inventory.
Buying from an experienced fabricator like BTL gives you a direct line to the people who work with liners every day, from backyard koi ponds to 40-acre irrigation reservoirs. An experienced fabricator can give you real-life validated, expert support from the moment you order until the pond is full.
