Anyone ever damproofed solid 215mm walls

Gareth2011

Hi Folks,

Just wondering has anyone ever damproofed (rising damp) solid 215mm walls with the stuff from damp store? My dad called them and they told him it was stuff you could pour in. I thought this was odd as never heard of stuff you pour in only inject. Anywho I called them myself and sure enough it has to be pressure injected he said its a silicone based soloution and it expands to form a barrier. Thats fine but this is 215mm solid solid walls with just cement or something else put onto both sides no drylining or anything.

My dad is going to help me with it but once the stuff is used as planned and then tanking is to be done. Ill have the plaster pelled off the walls where affected areas are.

Just wondering has anyone ever used this stuff im talking about? It not a basement its a bunaglow built in 1940's no call for dpc back then but now its getting unbearable with the cold Once I have the damp sorted then il look at insulation. Any help is appreciated

Hi,

There are a number of different ways to retrofit a dpc, it is vital to read, understand and follow the instructions of such injection treatments to the letter.

Very important to double check the warranty / guarantee and check that it applies to diy installation and that any guarantee offered is not subject to installation by trained / licenced installers.

Ask for the BBA cert and any other certification that is marked on the product because once you install it you could be making installation of another product difficult in the future should this one not work.

Most of the cost of installing a new dpc is in the preparation and finishing with that in mind you may wish to do a bit of research on specialist products and installers the fact that you are doing the preparation and finishing the cost could be less than you expect.

So you mean I take off the plaster and skirting boards clean off walls and see how much it will cost me to get a professional in to inject the dpc? Dont know how well that would go down with my father as it was his idea to help me do it :eek:

Hi,

There are other products available, just suggesting you look and see what options are available to you.

Not that many to stop rising damp tho. If I was insulating there are a few but not for the damp problem. Only way as far as I know is to put in DPC into the blockwork to form a barrier or there is the electro osmosis system.Unless you know a different way to stop the rising damp? Bear in mind im not what you call cash flush

Hi,

You have to read between my posts (or between the lines) to type it out straight could get me banned and no I'm not interested in doing your job.

Spend once on a good job that carries a proper guarantee and you can forget about damp problems, nothing worse than decorating the rooms and finding the same problem back again.

In addition to researching the injected /electro etc stuff, please research the options if you cant get satisfaction on such products.

Read around the subject and bear in mind that there are solutions out there such as, but not limited to breathable renders and ventilation.

Also the old reliable of putting a french drain around the house.

Are the floors concrete?.

There are many thread here on this subject

Its the old part of the house thats the problem think the wife calls them the old builders cottages. Its only 102 sq mtrs total and thats with an extention rougly same size onto the back of house. Only 1 floor is concrete whole way through others are wooden with a gap of about a ft or so from floor to ground which would be under the eye level of the outside path around the house.

Hi,

If the timber floors are below the level of path outside you need to do a bit of planning for this project because it is very important to have a through flow of air under the timber floor or they will rot away in a very short time.

You may not have to spend a fortune as a french drain and lower path outside could help to direct the water away from the walls of the house, I suggest start with the small details and eliminate the problems one at a time.
