I am currently planning to renovate my ground-level terrace, which is currently covered with concrete slabs. These will be replaced with WPC decking boards. Accordingly, a section of the terrace needs to be excavated to install the necessary substructure, as the terrace is intended to remain level with the ground (see image).
A discussion came up within my family, and I would like to ask for your opinion briefly. The excavation will create a hollow space, which will form the lowest point. During heavy rain, water could collect there and eventually find its way toward the basement. The house is a new build and only one year old. I assume that insulation and sealing standards were followed during construction. What is your take on this? Could this cause any issues, and is there something specific I should consider?
Regards

There could be water accumulation during heavy rain, which sooner or later might find its way towards the basement. If the soil is permeable, I don’t see this risk. Just dig a hole in your garden and pour in a bucket of water. Does the water stay standing? Or does it drain away?
Also, the substructure should not be directly exposed to rain. WPC decking boards usually direct water away towards the garden (a slight slope). Not enough water passes through the gaps to create a puddle underneath (assuming the layer is permeable).
WPC is a separate topic. What is wrong with the concrete slabs? Why not use wood? Or other types of stoneware?

twistedtails9 Mar 2017 19:34I will try the bucket of water test. But this problem affects all ground-level terraces, and I find it surprising that none of the guides online mention it at all!?
Regarding the surface material, I don’t find concrete slabs very appealing, and they get too hot in the summer for my liking. Wood requires too much maintenance; I want a surface that is easy to manage. To be honest, I hadn’t really considered porcelain stoneware. I initially thought it would be expensive, but I should probably calculate the costs first. After all, this option doesn’t require a substructure, and the effort involved is much less. However, I guess the heat issue would be similar to that of concrete slabs, right?
I like the look of WPC; it’s low maintenance, and I can avoid the heat problem.
