Hi everyone,

I've recently had building work carried out at my property through a Disabled Facilities Grant (DFG) arranged by the council.

The original specification clearly stated that the builders were to carry out damp-proofing works. However, I've recently discovered that they have used a tanking system instead of the damp-proof course I was expecting.

I'm concerned about whether this is an appropriate long-term solution and why the original specification appears to have been changed without my knowledge.

I'd appreciate some advice on the following:

- Is tanking as effective as a traditional damp-proof course?
- How long should a tanking system last?
- Should the builders have informed me before using a different method?
- Can I ask the council to investigate and ensure the work meets the original specification?
- Would I be entitled to request that the correct damp-proofing method be installed?

Has anyone experienced anything similar with council-funded DFG building works?

Any advice from builders, damp-proofing specialists or surveyors would be greatly appreciated.

Thanks in advance.
