Measure the area for your garden decking, then remove soil to around 50mm deep. Ensure the area is flat using a spirit level. A 2mm gradient prevents puddles.
Cut the outer joists carefully to size and lay them in place on their narrowest faces. Ensure the frame is flat and square, then mark two vertically aligned pilot holes at each corner – 40mm from the top and bottom of the frame respectively.
Cut the joists to size and attach them to the frame 400mm apart using joist hangers. Measure out and pre-drill holes into your decking boards or tiles. Countersink the holes for safety.
Use decking screws to attach the boards or tiles to the frame.
