There are many possible sources of water leakage/seepage which your toilet or bathroom could be facing. Toilets have many water supply, discharge and ventilation piping, any of damage or disconnection of such piping can lead to water leakage problems. However today we will focus on water leakage or seepage as a result of damaged waterproofing systems or concrete structures.
First,
Identify the source of water leakage. Is the water leaking from the ceiling of your toilet? Is the water seeping out from the walls of your bathroom? Is your neighbour directly downstairs complaining that their toilet is experiencing water dripping from their ceiling? To identify the source of water leakage is not an easy feat and you should engage a waterproofing specialist contractor to carry out a thorough and accurate assessment of your water seepage issues. There are many contractors who provide non-obligatory and free on-site consultation and you may wish to engage their professional services.
Identifying the source of water leakage is of utmost importance in the entire repair method. If the source of water leakage is wrongly identified, any form of repair will not solve the leakage problem and efforts and money will be wasted. It is therefore exceptionally important to engage a professional to accurately identify the source of water leakage prior to deciding on a method of repair.
There are a few common causes of water leakage in toilets and bathrooms, namely cracked concrete structures (due to either differential soil settlement or expansion and contraction) and weakened joints between discharge pipes and concrete slab.
Last but not least,
Once the source of water leakage has been accurately identified, it is important to look for the right contractor who is professional and competent to carry out the repair. To repair such water leakage problems do not necessarily require hacking the entire toilet above and re-waterproof, there are non-invasive waterproofing methods which do not involve hacking. Some of these non-invasive methods of repair are: 1. polyurethane (PU) injection grouting and 2. flooding the toilet surfaces with chemicals to waterproof without hacking. Therefore you have to look for a waterproofing specialist who is able advise you professionally on the different possible repair methods.
Furthermore, all waterproofing repair works should come with warranty. If the contractor refuses to provide a warranty for his repair works, it shows that he is not confident of stopping the water leakage or seepage problem. Look for a specialist who has a strong track record and is able to provide a reasonable period of warranty for the repair.
