How to stop rising damp?

[baselofbakerst]

Hi,

recently purchased an 1890’s rural home with rising damp. 
It is double brick with a veranda around external wall. It also appears to have slate acting as a damp course. 
My question is as I am able to access all walls through the underfloor should I use dry rods to stop this issue? 
I have seen them on YouTube and wondering if anyone has any experience using them. 
Also is it the best option? Are there cheaper or better methods to solve this issue?

Thanks in advance.

(i will also add flashing between timber and where it is in contact with brick.)

Hi @baselofbakerst,

Thank you for your question and welcome to the Bunnings Workshop community, it is great to have you with us.

I'm not aware of the product that you mentioned, but it looks like it might be a good option for you.

Unfortunately, I'm not aware of any other products that can be used in this fashion. The only other suggestion I have is to contact a company close to you that specialises in rising damp issues.

You might like to have a read of How to add damp proof course to fix rising damp for some further information.

Allow me to tag some of our helpful members to see if they have any thoughts or can assist, @Nailbag, @DIYGnome, @Dave-1.

Let me know if you have any further questions.

Good Morning @baselofbakerst 

I have not heard of the dry rods (just went and had a look at them) Not sure if I would trust them mostly because Ive never come across them before and figure if they are well known then thats a plus that they work.

I would probarly go downthe route of more ventilation under the house, something that allows cross breezes to dry out the ground and brickwork so the damp doesnt get a chance to contine up the brickwork. In an older place I would definently get someonequalified to install open airvents as the state/way the bricks have been laid could cause structual issues if disturbed. I would even go the route if install under floor exhaust fans to draw air through the space if it was bad enough.

HI @baselofbakerst I've actually not heard of dry rods, but I do know that increasing cross ventilation under your house can make a significant difference in reducing rising damp. This is done by replacing one or more bricks below floor level, either between the floor and joists or below the bearers around the house and above ground level. They are available in several designs and a relatively easy DIY project.

Many thanks,

I have spoken to a couple of other people with similar issues and they have recommended the same course of action with An extraction Fan so will definitely add that to help with the issue.

Hello @baselofbakerst 👋

Those hot rods look quite intriguing... without actually getting to inspect one they appear to be a porous (or perforated) tube which provides an alternative exit path to moisture within a wall structure, clever in theory but I have never used/installed them.

I would concur with the suggestions for additional ventilation in your subfloor and have noted solar extraction fans designed specifically for this purpose but would suggest the passive grilles are significantly more please aethsetically.

Many thanks @Nailbag.

ill investigate further and definitely add some more ventilation to the area. 

Best,

Basil
