This committee oversees the work plan that covers the evaluation of cementitious and resin based spray applied liners for storm water conveyance conduits. This work plan utilizes laboratory testing to evaluate material used for the spray applied liner. Different laboratory material testing is required for the resin based liner versus the cementitious liner. An optional structural test is included in the work plan.
This work plan (located under Documents on the right side menu) is intended to determine the material, durability, application properties, composition properties, and structural capacity of each liner. Acceptability of each material, based upon the data generated as a result of the testing and evaluation in this practice, is the responsibility of the user. Structural design methodologies of spray applied liners are not covered under this standard practice.
