Here’s an indoor wooden balau pool deck we built in Estcourt KZN recently. The client had been doing some renovations on his house and had enclosed the pool with brick walls and windows resulting in an indoor pool. He wanted a wooden deck around it to finish it off nicely.
Careful consideration was needed to ensure that any water from the pool could quickly drain away so as not to remain wet beneath the deck boards for too long. Of course with an outdoor deck any rain water or pool water evaporates quite quickly and isn’t of that much concern. Being indoors however this water can get trapped below the deck for some time resulting in premature failure of the timber. Although the timber is H3 CCA treated, and as such can live outdoors with periodic wetting, it cannot remain wet constantly. H4 CCA Treated timber is more suitable for damp conditions such as constant contact with wet soil. But a fair amount of water on an ongoing basis is not a good idea.
In this instance the builder had done a great job in creating a small fall on all four sides of the pool so that any water dripping or splashing on the deck would fall back into the pool rather than sit below the deck.
The job was relatively easy as there was very little difference in distance between the walls and the sides of the pool. If the wall is not parallel to the pool then it will result in a wedged shaped deck board either up against the wall or the pool. To counter this one must “fan” the deck boards by making the gaps on one side 1mm smaller than the gaps on the other side effectively gaining 1mm per deck board. After 20 deck boards you will gain 20mm to make up any difference.
In fibre glass pools one might also find that the edges of the pool are not straight. Run a fish line along it to see if it bulges in or out and find the straightest side to start your decking. If it does bulge then you will need to overlap your deck board on the pool side slightly to cover that and keep the deck boards straight.
A simple single deck board as a fascia board on the inside of the pool finished it off nicely. It was oiled with a deck oil and this deck will require very little maintenance or re-oiling as it is indoors and won’t get any sun.
