The Causes of a Leaky Shower

Whether you have a stand-alone shower with its own tray sitting in the corner of the bathroom or you have a shower head and screen in and around your bath, one issue you no doubt consistently come up against is that of leaks caused by the sealant as well as the dark, horrible mould that thrives in a damp conditions.
There is nothing worse than looking at the perfectly white tiles (or any other colour you have happened to choose to decorate your bathroom in!) around the bath or inside the shower cubicle and seeing the silicone gel or sealant looking anything but at the pristine colour it was when first put on the join. It happens to all of us, no matter how often you clean the bathroom suite or how little you use it. It is as much the natural dampness or bathrooms that cause it than anything else.
The constant change in temperature means that the silicone will lose its shape. It would anyway to be honest due to the nature of it, but the bathroom environment and the water hitting each every time the shower is used means that the silicone sealant loses it adhesion and will ease itself away from the edge of the shower tray or tiles to create an area which could leak. As it ages and loses its natural shape, the mould begins to grow and adds to the problem.
It could well be that the weight of a person standing in the shower adds to the problems too. Whenever you are trying the silicone for a leak, you are unlikely to be trying the shower in its usual full working capacity in terms of a person occupying the shower, so test it while inside (wear some old clothes while doing so). You will soon notice if a person is the problem in the respect that their body weight stretches the silicone out of position due to its lack of elasticity.
The best and easiest solution is to use an alternative to silicone, which a) does lose its adhesive-ness as quickly and b) which is better suited to the conditions of a bathroom. The substance in question is a polymer has been developed to become the most durable sealant substance on the market. It’s ability to cope with the type of water a shower is likely to throw at it is the key factor with the sealant maintaining its shape and adhesive quality regardless of the wetness. In fact, it can be applied on a wet surface without negative impact and is also used in underwater areas too such as swimming pools. Perhaps even more importantly, however, is the fact it offers flexibility and will maintain the seal over an area even if the shower tray has dropped a millimetre or two for example with the arrival of human bodyweight in the tray. With silicon, that is likely to be that start of your problems and leaking area, but not with a polymer.
If all of your tests prove inconclusively that the silicone seal is the problem, then it could be the grouting in the tiles that is the issue. Grout can break away or crack and therefore leave gaps for water to swap through, so check there are not issue with the grout. If there is, using a small tool scrape away the existing grout and re-grout to eradicate the issue.
