This is exactly what i need to do on my garage. Thanks for the video!

Looks very similar to what I need to do. I have a end Terrence house and the same is happening as the walk way at the side has been built up over the years and is over the damp course. Great video. Thank you.

Perfect mate this is exactly what I need it for.

This is literally the same issue I have with my garage and someone quoted me £300 to put sand and cement around the base of the garage. Lucky I found this video lol nice one

Spot on my friend. I have a concrete sectional garage with internal cement fillet seals totally useless. Why do the manufactures instruct this procedure ? As you demonstrated I cleaned the outside of the bottom edge then painted a flat roof repair / sealant around the base. now no dampness :) Great that you are giving advice to solve problems.

Nice one. Adding a cement filet on top of that blackjack would protect it to last a bit longer, otherwise blackjack by itself could get damaged/worn over time. Or you could always also another coat on if that happened I guess.

Any update on this? Did it manage to keep the damp out after a few weeks?

Mate, I’ve been bitchin, wineing and moaning about the garage roof replacement company that installed the garage roof a year or so ago, turns out it’s not up top. As your quick guide says, it’s water ingress along the side of the garage where the earth is high up running into and through the single skin brickwork. Tommozer, I’m going to Wickes and getting me some blackjack, bit of digging and BOOM that’ll be job done. Thanks and Thanks again, you hit the mark, no fannying around. Just say it how it is………We’ll done boys

Thanks for the video mate. I have a similar problem in my garage the water tracks in from above the exposed slab on the outside. The gap between my garage and the neighbour's is only about six inches so I can't get to paint on the BlackJack. Thinking of pouring tanking slurry down the gap to raise the level above the slab, any thoughts?

Hi mate. I have the exact same problem. How dry does the existing mortar have to be before you put the stuff on.? Don’t suppose you know if it’s still working sound?

got the same problem with my garage and was looking at doing the same thing can you put a layer of cement on top of the dpm?

Hi there what is a good idea to damp proof the garage concrete floor

What do you use to stop the water getting in?

What would you suggest if you can't access the bottom of the exterior wall? Is there a way to damp proof from the inside?

Do all single brick garages leak in water or is it that this one was built poorly. My garage is single brick and hasn’t leak at all yet

Hi. Thanks for the brilliant video. I was just wandering ....... we had a builder come in and damp proofed our little cellar with this. He left lots of marks on the wooden skirting boards. I was wandering how do you take the damp proof of or remove it from a wooden skirting board? Methylated spirit didn’t work. Thank you in advance.

I have water coming in from the bottom and at the top on the sides. Can can I solve that?

What about painting the outside wall with stormdry cream lasts 25 years. Amazon £107 pounds

How to do just from inside ?

Can you use Liquid DPM on the internal floor for a wooden shed? The floor is wooden. Thank you

Can u do the whole garage floor in this paint

Did the blackjack work?

Whats the product you use

Can you do this on the inside as.i can't get around the outside

Over garage has no dpm, would this help,

My garage is single skin with no DPC would this still work?

Is the bitumen still there? I want to paint one northern wall

In Wickes they do not sell this no more
