I was recently advised to apply tanking slurry to a part of my brick garage wall about 3ft x 3ft due to water ingress. I've applied this as directed in the instructions and now have condensation forming on the tanked part of my wall. This is creating more water than there was before I applied it.
Am I missing something here ?
Should I apply the slurry to the same part of wall on the outside as well ?
Is there a cure for this?
Any help or advice would be appreciated.
Thanks
