Failed Tanking

what happens when tanking fails


Freephone :

The reasons for failed tanking

Even tiny cracks in basement tanking can allow considerable volumes of water to seep through. 

Tanking can fail for a number of reasons:

  • Vibrations in the ground from passing trains or small earthquakes
  • The property settling into the ground
  • A build-up of hydrostatic pressure behind the tanking system

Because the majority of tanking systems are cementitious, they are inflexible. This means sufficient external pressure will cause tanking systems to crack and ultimately fail. Internal and external basement waterproofing methods are available to replace failed tanking systems.
