Damp proofing a garage
Turbo Mini Forums

I know there has been a few posts over the years on this but could not find what i wanted.

I have a double and single garage and currently the single garage roof is shot and leaking in a couple of places, now i have moved averything out the single of value over the last few months as the roof has got worse and the lack of space really is hampering my progress on anything.

I am putting a new grp roof on the garage this week however i think i get a bit of damp comes up through the floor and the lower bricks as well as i painted the floor and its lifted and powdery in places, has anyone damp proofed their garage? i would like it for storage of most of my parts and to site my lathe in so need to get it as dry as possible so any ideas would be great.

I used KA tanking slurry on the outside of our garage and put in a french drain. Water would run through the garage in the pissing rain as the wall retains about 5-6ft of sand.

I was going to use it on the inside of the garage to if any water got through but it hasn't so far. You can also use in on floors but you'd have to put anything like that down quite thick to get strength.

Got it from here, free delivery on a certain spend.

Edit: I bought 100kg, this did a thick coat accross the back of small tripple garage with some to spare.

lol i had a concrete sectional that leaked quite badly replaced the roof with osb boards and felt 10 years ago it was great. smashed it down in nov waiting for the builder to fit the master bedroom on the top now !

no help i know. could you not get some damp course and screed over the top ?

I done my previous garage walls coverd with cement that is used in basements? ( under the ground also used to store wine or hide death people ) the floor was then covered with a sort of tar but not the sticky kind. Should do the same with the new garage but its a bit to big for that. Also had a dehumidifier in there running 3 hours a night.

you can do anything if you set your mind to it...
i rather blow it up winning than keep it together losing.

finish date set for project 1... march 2018

neil , is it worth doing the roof ,and some proper guttering ,and see if it all dries out ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

Id say with the roof done it may well dry out. Mine has gone all moldy this winter and ive just noticed a small leak. You'd be surprised what a little bit of water hanging around does.

theres a product you can't paint on like an industrial trade pva id assume might be worhlooking into i can't recall the name sorry

I used tanking slurry on mine, I got it from tool station, £20 for 20kg used x2 tubs, (single garage) just did it 4ft high from the floor up the walls and did the entire floor. Then painted the floor and walls afterwards.

Cat little boxes, the crystal type, I keep one under the mini, one under my tools and one under power equipments, works well for keeping moisture out that area, change it every 6 months.

I know it doesn't help that much right now but long run it may.

Searching is all you need on TurboMinis

I'd fix the roof first and see what that does. Tanking slurry may be an option if there isn't already a dpm installed but check the wearing capabilities of them. Some don't have a great resistance to impact and point loads

Thanks chaps, i will see if the weather is good enough for fiberglassing tomorrow and go from there.
