Dryrod damp proofing, does it work?

[yartin]

Hi
I just come across a video using Dryrod to solve rising damp issue in cavity walls, it looks to easy DIY which made me curious, does it really work?

How did you determine the cause of the damp . A wrong diagnosis will result in a wrong solution .

Which damp?!
I came across a video and just curious if such simple DIY works.

No

You have to find out where the water is coming from, and cure the defect or source.

Every square metre of your wall has a square metre of bricks that water will evaporate off if you let it. What will you gain by drilling a 25mm hole in it and inserting a rod?

It works to extract large amounts of money from people when they are installed to solve problems that don't exist.

Seems no one has used them, just opinions.

Post a link to the video and we may understand better how they, (supposedly), work and with what type of damp.
I.E rising, penetrating, condensation, etc.

You can find them here: https://www.wickes.co.uk/Dryrod-Damp-Proof-Course-Rods---180mm-Pack-of-10/p/133882 (as an example)

Reviews say that they are easy to install (drill 12mm holes 190mm deep and 120mm apart in a mortar course and shove a rod into each hole). There don't seem to be any reviews on that site which say that they have actually cured a problem.

They are made of porous ceramic. Bricks are made of porous ceramic.

Edit
The Wickes ad says that this version includes a silicone agent in fibre.

They're available from the likes of safeguard, a respectable damp proofing agent and are also BBA certified, again a respectable standard so perhaps they have they're uses in the right situation https://safeguardstore.co.uk/dryrod-damp-proofing-rods/

It seems to me that they leak WD40 into the middle of the bricks to stop moisture passing through, then it is not a proper porous brick any more.

My old (damp) house had some strange strip of copper pointed into the brickwork and connected to an earth rod - looked highly technical but didn't stop the damp.
