Browse Forums Pools & Spas 1 Nov 10, 2014 8:51 pm Hi all We are planning on constructing a pool at our new home and having difficulty deciding between concrete and fibreglass as both appeal to us in different ways. Our site is about 2.5m of fill which is predominantly silty clay. Just wondering if anyone has any experience with constructing a pool with this soil type? I have read that clay is quite expansive and the movement in the soil can cause the pool to crack. There seems to be conflicting information on the internet depending on whether it is coming from a concrete pool builder or fibreglass pool builder. Thanks in advance I've dug some footings to embed a post anchor into. My holes are around 450mm deep which I'll put a 200mm stirrup into. The bottom of these holes seem firm enough. … 0 1547 Thanks for your reply. I will just wait and see I guess. Trying to get some more information from our builder. 9 11727 I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills. 2 8270 |
