Ive just bought 6 wood decking tiles for an area of garden ive levelled out, added weed fabric, and covered in gravel (roughly 20mm ) Please login (registration is free!) to view this link. http://www.awin1.com/cread.php?awinmid=483&awinaffid=58258&clickref=xf&p=http%3A%2F%2Fwww.diy.com%2Fnav%2Fgarden%2Ffencing-paving-decking%2Fdecking%2Fdeck_tiles___frames%2F-specificproducttype-deck_tiles%2FB-and-Q-Square-Deck-Tile-L-600-W-600-T-56mm-9276085%3F now would i need to make a frame for these, or have them raised further? Or are they ok just to keep laid down? btw the tiles are 600mm x 600mm x 42mm (not 58mm) Im going to lay them 3 wide an 2 deep. Do i need to just frame them in all together with 42mm high boards, or raise them all on top of joists n bearers? Im just really confused as to what else i need now. Any help much appreciated. Thanks in advance.
