I’ve been meaning to feedback for a year or more now. Basically bought the Hollow composite board, it’s atrocious, laid it with 1:100 fall like a normal deck, the board has split and buckled all over the place. It’s crumbles under pressure, the 50% bamboo fibre is not fit for purpose in this country ie frost & wet ....£2,300 of rubbish the composite boards are the same water sits in them and freezes... I’m a professional and fully registered with 25 yrs experience. Edecks washed their hands of it saying I didn’t use end caps that’s why it’s like it is in the state it’s it in. Basically I had to relay new deck for client using a quality board from Millboard. Do not use this company Edecks terrible products and customer care. I note they have discontinued the hollow board due to so many problems. Shame they couldn’t hold their hands up at the time I originally complained over a year ago. Do not use Edecks.
