When it comes to basement waterproofing, there are three main types of basement waterproofing systems available for your property, ranging from traditional methods like tanking to more modern internal water management systems.
Basement tanking is a traditional form of basement waterproofing. It involves putting a waterproof render such as a waterproof cement or slurry on the internal walls to form a ‘tank’ that stops the water from entering. The render gives a smooth, seamless wall surface which looks good and provides moisture control.
Being a traditional form of basement waterproofing, there are issues with this basement waterproofing system particularly if the area you live in is susceptible to ground movement or vibrations. That said, it can be an ideal solution for certain spaces.
Basement waterproofing from the outside is another concept that has been around for a long time. Exterior basement waterproofing systems are often installed to protect foundations of properties during construction.
In recent years, the most common form of exterior waterproofing is the use of either an external membrane or cementitious render on the external foundations in conjunction with a traditional French drain that runs along the outside of the property, below ground. This helps manage excessive levels of ground water that can cause hydrostatic pressure to build up against underground foundations.
While this solution can be successful in construction projects, it is not ideal as a retrofit solution as it does involve serious excavation. Retro-fit French drains are also susceptible to clogging from surrounding slit and soil.
Basement waterproofing from the inside is the most modern method of basement waterproofing. Originally pioneered in the USA, these clever "water management" systems are now used worldwide.
Rather than allowing ground water pressure to build up against a cementitious barrier or an external membrane, water ingress is instead allowed to enter the property and then channeled back out using a combination of internal membranes and innovative basement drainage systems. A sump pump will then remove any water safely and efficiently. This method ensures that basements, cellars or any other space below ground level can remain dry without any external excavation. These systems also remove the risk of ground water pressure building up to a point that a physical barrier would crack.
Moreover, there is one last major bonus... these systems tend to be far more cost effective and easier to install.
