A NEW CONSTRUCTION CONCEPT WAS DEVELOPED PRIMARILY TO PROTECT CANALS AND OTHER WATER-WAYS FROM SCOUR AND EROSION. IT INVOLVES PLACING DOUBLE WALLED CLOTH MATTRESS MATERIAL OVER THE BANK OR OTHER AREA TO BE PROTECTED. THE TWO LAYERS OF CLOTH, PREFERABLY NYLON, ARE WOVEN TOGETHER EVERY SIX OR EIGHT INCHES AT TIE POINTS. MULTIPLE SECTIONS OF SUCH MATTRESS MAY BE JOINED TO COVER WIDE AREAS. WHEN PROPERLY POSITIONED AND SECURED, CEMENT MORTAR IS PUMPED INTO THE MATTRESS TO INFLATE IT SO IT RESEMBLES COBBLESTONE PAVING. THE SIZE OF THE COBBLES DEPENDS ON THE SPACING OF THE TACK POINTS. ONE SECTION IS PUMPED AT A TIME UNTIL THE SCHEME IS COMPLETED. THE SYSTEM CAN BE USED TO PAVE A STREAM BED BY STRETCHING THE MATERIAL FROM ONE BANK TO THE OTHER, EVEN WHERE STRONG CURRENTS EXIST. THIS DUTCH PROCESS IS BEING INTRODUCED INTO THE U. S. CONSTRUCTION INDUSTRY UNDER THE TRADE-MARK FABRIFORM. NEW APPLICATIONS SUCH AS PILE JACKETING, TUNNEL LINING, BEACH PROTECTION, SMALL DAM ENCASEMENT, ETC. ARE BEING TESTED OR STUDIED.
