Decking – grooved or smooth?
A grooved board offered no advantage over a smooth one in terms of slip resistance.
The benefit of grooves is they aid water runoff. However, they only do this effectively if they are installed with sufficient fall and in fairly short lengths. If you are using long board lengths e.g. greater than 3.6m, the grooves are always going to hold water due to surface tension properties. In this case it is much better to use a smooth board. Grooved or ribbed boards can also be used alongside smooth deck boards as a design feature.
The good news is that we now stock dual purpose boards offering you two surface style options. Simply lay these with your preferred option on top.
