EXPERIMENTAL MACHINE FOR LAYING MEMBRANE WATERPROOFING

A ROOF FELT LAYING MACHINE WAS USED IN AN EXPERIMENT IN LAYING DOWN MEMBRANCE WATERPROOFING. SPECIFICATIONS FOR MEMBRANCE WATERPROOFING IN THE DISTRICT OF COLUMBIA ARE DISCUSSED. DIMENSIONS OF THE RECTANGULAR TANK AND PROCEDURAL DETAILS ARE DESCRIBED. THREE PROBLEMS ENCOUNTERED IN PRACTICAL EXPERIENCE, AND THEIR RESULTANT SIDE EFFECTS ARE OUTLINED. POSSIBLE SOLUTIONS ARE SUGGESTED. IT IS NOTED THAT THE MEMBRANE WATERPROOFING PLACED BY THIS MACHINE DURING THE EXPERIMENT WAS NOT ACCEPTABLE TO THE DISTRICT DUE TO UNEVEN APPLICATION OF THE ASPHALT AND FABRIC AND USE OF OIL TO KEEP THE TIRES OF THE MACHINE CLEAN. MODIFICATIONS TO THE MACHINE TO OVERCOME THE PROBLEMS ARE PLANNED.
