Hydraulic conductivity studies of a consolidated pozzolanic material indicate that heat-shrinkable tubing can be utilized to encase cylinders for use in a permeameter. The materials required for encasement of a sample include: heat-shrinkable tubing, hose clamps, polyvinyl chloride discs, glass tubing, and an electric oven. The procedure requires that the assembled PVC discs, filters, shrinkable tubing, and sample be placed on a support stand in an electric oven for three to four minutes at a temperature between 450–500° F. Upon removal from the oven, hose clamps are placed around each PVC disc. The method has several advantages. It saves time and expenses over conventional methods such as pneumatic pressurized core holders or triaxial testing units and preserves the original interstitial bore spaces of the sample.
