Addendum to 1987 Final Report. Short brief of the construction and reference to previous recommendations, major objectives, and notation of conclusions. Findings, observations, and pictures showing long term effects to fabric fonn. Conclusions and recommendations for long term effects. This addendum constitutes a follow-up to Item 2114; 81-08-1, "FabricForms". Major Conclusions: Fabric Form can be utilized with little preparatory work. Nylon resists ultraviolet radiation and bonds with the mortar mix better than the polypropylene. The pillowed effect of the fabric collects sediment, thereby encouraging vegetative growth. Weep hole should be used. Lesser slopes result in greater abrasion to the material.
