High water table pools

Outdoor fibreglass drop in pool with high water table. GRP lining refurbishment.

We were called in to refurbish an outdoor fibreglass drop in pool. As you can see from the photos below this particular swimming pool has buckled around the walls and floor and has also cracked in some places. Although this is an uncommon occurrence with fibreglass drop in pools, such damage can be possible over time due to a high water table and many winterisations. The cost to remove and replace the whole fibreglass drop in pool would have been considerable, the customer was not concerned with the aesthetics of the bows in the pool but did want to regain functionality of the fibreglass drop in pool. This is where we recommended our cost effective solution, our fibreglass lining would regain functionality of the pool by sealing the cracks completely, as well as giving the pool back its strength. When we first started work on this project the bowed floor was completely filled with water and bounced up and down when we walked on it, reminiscent of standing on a water bed. However, when we had finished the in-situ fibreglass lining, we noticed the floor was much rigid and no longed moved. This is an example that demonstrates how effective our linings are at increasing the structural integrity of the swimming pools that we work on . As you can see from the after picture the cracks in the pool were repaired and the fibreglass drop in pool was given back its functionality. We were very pleased with the outcome of this project as our extremely cost effective fibreglass lining was, to our knowledge, the only solution to giving this pool a new lease of life short of an entire drop in replacement.

Domestic indoor swimming pool with severe water table.

As you can see from the photos below this swimming pool was originally fitted with a plastic liner and fibreglass steps. When the liner was initially installed there were no water table issues apparent. However, when the pool was drained down for subsequent maintenance it was found very quickly the whole of the liner was floating. This was due to a large volume of water coming through cracks in the bottom of the pool, upon site inspection it was discovered that the building of a recent housing estate close to the property had diverted a large underground aquifer straight underneath the swimming pool. At only 1m below ground level, the water table was substantial and without any intervention the ground water was able to fill up to 2/3rds full. This is demonstrated by the video below which shows the water spouting through a small hole in the steps. Due to this water table problem, a refitting of a plastic liner was no longer possible. We were called in to fit the whole pool with our GRP lining, this was by far the worst water table we have ever encountered, however we were still able to successfully carry out the in-situ lining. As the pool was 100% waterproof after our work was finished the pool was immediately filled to counteract the outside pressure and is now a stable and working swimming pool. We were very pleased with the outcome of this project as to our knowledge there was no other solution to return this swimming pool back  to working condition.

Domestic pool with wrinkled liner and high water table

This is a domestic swimming pool we worked on which was originally fitted with a plastic liner. As you can see from the before picture the plastic liner has become severely wrinkled. This occurs when the pool is heated past a certain threshold which subsequently expands the plastic over its original size, leading to wrinkling. In this case the liner had wrinkled within the first 6 months of being installed! Of course this is unpleasing aesthetically and was subsequently removed to be replaced by our GRP lining. The benefit of our GRP liners is that we pride ourselves on using only the best materials, this means that our GRP can withstand swimming pool water temperatures up to and over 100ºC, therefore removing all fears of such wrinkling occurring again. Upon removal of the liner we found that the ground surrounding the pool suffered from a high water table, and over the years this had weakened the render and allowed water into the pool. However, as we at DRFS have had extensive experience working with high water table issues in swimming pools we were successfully able to install our new GRP lining which gave the pool back its structural integrity as well as making the pool water, heat, chemical and wrinkle proof. This swimming pool was finished in white which when filled with water makes the pool look blue, to see how this works please visit the page on our site http://www.fibreglass-lining.com/other/white-pool-turns-blue/

This swimming pool was in a terrible state when the plastic liner was removed. The galvanised panels were falling off and rotted through, and the render forming the base of the pool had completely lost its integrity, coupled with a high water table surrounding the swimming pool it was no surprise that this pool was letting in a significant amount of water. There were few solutions to rectify this swimming pool short of a complete overhaul. However through years of working with pools that suffer from high water tables we were able to successfully line the pool using our GRP system, not only did this give the pool a new lease of life as it is now 100% waterproof it also allowed the pool to regain it’s structural integrity. Found below are the before and after pictures as well as a link to our Youtube video showing the severity of the water ingress. We believe this level of refurbishment gives testament to our skill and our product and we are very happy with the results.
