Tanking of prefabricated basements

Detailing the available solutions

Every prefabricated basement needs suitable tanking. It serves to protect against soil moisture and ground water and should provide total protection against damage to the building fabric over many decades.

The question of which tanking system will suit a basement project is a vital one to answer correctly. While Glatthaar customers will always be assured the perfect tanking is used for their specific property, it may be useful to understand the various methods for tanking a prefabricated basement.

Internal tanking: a solution for semi-detached and terraced basements

Internal tanking is a solution relied upon when all of the external walls of a basement are not accessible from the outside. This is most commonly the case for semi-attached and terraced basements but also comes into play when certain site conditions restrict full access e.g. a property is constructed close to dense rock which limits the ability to carry out surrounding excavation.
These situations are relatively rare and therefore internal tanking is a less commonly used solution.
So while professionally installed internal tanking for a prefabricated basement can provide a good protection against the ingress of water and soil moisture, applications are limited to specific use cases.

External tanking: the preferred choice for accessible sites

Where outer walls are accessible, external tanking should always be a preferred choice. External tanking can be rigorously checked after completion and any irregularities quickly identified and refinished.
When choosing a plot for a new build featuring a prefabricated basement, where feasible, it is advisable to select a site which will allow for external tanking as this is proven to provide more robust, long term protection.
