摘要： A tubing with improved compression strength for a subsurface water drainage system comprising a core polymeric support structure wrapped longitudinally in first and second geotextile materials, wherein the core polymeric support structure is heated to soften the polymeric material and wherein the first and second geotextile materials overlap and are adhered together with a hot melt adhesive and tensioned to tightly wrap the core, thereby forming the tubing.
