Common use of Joint Formers Clause in Contracts

Joint Formers. Closed cell expanded polyethylene joint formers shall have the following typical properties: Property Unit Value Value Test Method Density kg/m3 110 DIN 53420 Property Unit Value Value Test Method Compression Stress at compression kPa 175 DIN 53577 strains of 10% kPa 210 DIN 53577 kPa 340 DIN 53577 25% 50% Compression set after 24 hours recovery % 14 Tensile Strength kPa 680 DIN 53571 Elongation at Break % 49 DIN 53571 Max. water absorption after 24 hours by volume % 0,1 ASTM C-177 Joint formers shall be pre-cut to suit the application as per drawings with a tear-out strip for forming the specified recess for the sealant. The joint formers shall be developed for use in applications with a head of water of at least 10m. If so required the filler shall be glued into position with approved epoxy glue. Joint formers will be used for expansion joints in the walls and roof and as indicated on the drawings. Joint formers will also be used where the perimeter walls are cast up to the beams and shall have a thickness of 12 mm. Where this is the case, the joint formers will be cut out to a depth of 12 mm to allow a cavity for the application of an approved 12 mm x 12 mm UV resistant polyurethane sealant.
