In case you are going to put up a terrace with hardwood, it is very important to account the natural shrinkage or expansion (movement in service) of the wood. During typical and natural expansion and contraction the terrace planks will, by their own nature, determine the easiest pathway to move.
The reason Deckwise® Invisible Terrace Fixings work so well is because only one side of the timber plank is fastened to the underlying sleeper. This permits the opposite side of the plank to move naturally. This simpje terrace fixing method guarantees even gaps over time as well as end-to-end terrace planks.
