Cause of swimming Pool Leak FoundHave you ever looked at your swimming pool and had that strange feel that something is not right? The water level appears lower than you left it yesterday, the pavement and grass near the pool looks wet and saturated?

Well, you aren’t alone; hundreds of homeowners across the UK have to contend with leaking swimming pools each year. The tricky thing with leaking swimming pools is that more often than not, the leaks are hidden and hard to detect.

Before you start fretting and looking for a professional, it makes sense to acquaint yourself with the 3 major causes of swimming pool leaks here in the UK;

  • Wear and Tear; Vinyl and marble are common materials used in pool construction. Like any other material, they too suffer the effects of wear and tear after prolonged usage. While these two materials have smooth and shiny surfaces suitable for lining the sides and floors of swimming pools, they aren’t impervious to wear and tear. When vinyl starts aging, it allows water to leak through your pool. It’s very recommendable to engage a professional leak detection company for regular and constant leak inspections. Don’t wait until you’ve noticed a leak; regular leak inspections and tests will help detect problems well on time. This way, you can get the leak fixed and save yourself major repairs in the future.


  • Ground Movements; ground movements are a natural phenomenon. Tectonic movements caused by various geological activities beneath the earth’s surface are responsible for some pool leaks. Regardless of the construction materials, earthly movements in the name of earthquakes and tremors will always have an effect. Rocks beneath the pool pierce right through the vinyl and marble, hence causing small leaks. With time, the leaks become bigger and before you realize it, you have a major hazard staring at you. There’s need to call in professionals such as ADI leaks who can detect leaks in their very early stages using non invasive methods.


  • Poor workmanship; remember the old adage that cheap is expensive? This makes much sense when constructing your swimming pool. Cheap construction materials may paint a picture of all being well for some time; but with time, cheap will come to haunt you. For instance, a pool made of resin and fiberglass may not be as robust and durable as sprayed concrete or concrete steel. The cost of constructing a swimming pool in the UK ranges from £ 20K to £ 75K, depending on the materials used, design, and so on. While expensive isn’t always a guarantee of higher quality, you should likewise avoid cheap quotations as your pool may start leaking sooner.
