As with liquid injection systems, cream based treatments rely on the competence of the installer for treatment to be successful.Injection holes need to be fully cleared of drill dust and debris before the cream is injected, and it is often difficult to know if each injection hole has been completely filled with cream.Furthermore, damp-proofing cream can sometimes drip out of the injection holes after treatment, reducing the effectiveness of the damp-proofing treatment.
