Hi,

What are the different methods of damp-proof coursing available?

Any opinions on the simplest and most cost-effective way to do this?

Doing a search on the forum revealed a product called Techdry, someone mentioned a $600 cost to damp-proof a whole house using this product...

I have also heard of the Trojan waterproofing system, but donīt know much about this or the costs involved...

Any comments appreciated...

Anyone put a new dampcourse in their property before?

Usually when putting a DPC down its a embossed black polythene plastic, looks like black plastic but its alot thicker, or you can use bituminous coated non-ferrous metal like copper or aliminium. It also depends if your house is or will timber cladding or brick veneer.

you may want to specify that it's a retrofit dampcourse you're looking at rather than fitting a dampcourse to a structure as you're building it.

due to a variety of reasons - inadequate technology/knowledge way back when or dodgy practices in the recent past, lots of buildings don't have any/an adequate DPC. There's quite a few "cures", some of them probably no better than snake oil.;)
