I spent $800 to cover my balcony in Chengai Wood decking. Despite being treated and varnished, in less than 6 weeks the wood is cracking, splitting and warping ! In one place the crack is 4 inches and the other its 2 inches. There are also smaller 1'-2' cracks at the joins. The carpenter did advise me to use short wood strips across the balcony width but I think thats ugly so I asked for longer wood strips to span the length of the balcony. He has replaced the 4' cracked area but I feel like asking for my money back ! Has anyone else had such problems ?
