We see this type of damp proof course throughout the UK and they are normally associated with Frank Schijver. In the many years that I have been coming across this type of DPC, i have yet to see one that is actually performing any useful purpose. The target audience for this type of DPC is generally senior citizens who have seen adverts in the national press and like the fact that they do not have to remove the internal plaster (a big selling point of the installers) so it is seen as an attractive solution. In most instances, there is no rising damp present, but even where rising damp is present, these types of DPC's offer no protection. Once installed, the company says you must allow a period of up to 5 years for the internal walls to dry out although, in my experience, they have not accurately diagnosed the cause of the dampness the walls generally do not dry out at all.
Avoid at all costs.
