WEC installs HDPE/LDPE/LLDPE rollout sheet liners for secondary containment and primary containment projects. These liner systems are popular due primarily to their low initial material cost and ease of installation. They have excellent chemical resistance characteristics and have thus been successfully used in the Oil and Gas industry for years. WEC stocks a large selection of sizes and can fabricate a liner to any size based on the needs of the client. Seam welding is easily performed in both a shop or field environment to address the specific needs of each job.
