Gunite vs. FibreglassFor those that can, swimming is pure pleasure. Owning a swimming pool, if you can, is just another level of bliss. No more having to share with the whole neighbourhood, bad habits and all! South Africa is the land of sun, fun and swimming pools, at least in some areas and for those if you are thinking of spoiling yourself you need to understand your options. Putting in a swimming pool is not a cheap exercise. Besides which, once installed it becomes a permanent fixture so you need to get it right first time. There are only really two basic types of in-ground swimming pools, Gunite (or concrete) or fibreglass. Gunite or fibreglass as the most prolific in South Africa though, but I will tell you a little about vinyl pools anyway. Vinyl pools offer nothing more than a high-density liner, seamed together at the sides of the pool. Polymer or steel walls are first attached to the concrete surface and the vinyl lining is then spread over it and connected at the top by a vinyl rib at its outer edge. Initial outlay for these types of pool are fairly inexpensive compared to either Gunite or fibreglass. They take less time to install but over time the liner can be scratched, ripped or cut by sharp objects such as pool cleaners. Repairing a vinyl liner entails replacing it in its entirety. It really is nothing more than a type of shower curtain, but one that is exposed to heat and chemicals on a daily basis, encouraging the growth of algae and bacteria in the seams, especially. This takes high dosages of chlorine treatments to keep it at bay which is an added monthly expense. On top of that if you intend install a pool heater, you will find your running costs higher if your ribbing is made out of steel. So, if vinyl is out of the question the only other options are either Gunite or fibreglass.
