Rising damp?

    Looking for some advice.


    I recently moved into a new house with a detached garage. I had the roof renewed less than a year ago and have noticed that it's showing damp patches and is covered in mould.

    As can be seen in the 1st image, the floor is wet and appears to be seeping in from ground level. There appears to be a damp proof course as I can see it above the 1st row of bricks.

    I've attached a further photo of what is on the outside of the garage.

    Looking to see if anyone can tell me what the problem is and how I can fix it quickly as I need to roof to dry out before it's beyond repair.

    Thanks in advance. IMG-20190127-WA0010.jpeg IMG-20190127-WA0008.jpeg IMG-20190127-WA0010.jpeg IMG-20190127-WA0008.jpeg IMG-20190127-WA0010.jpeg IMG-20190127-WA0008.jpeg

    Is the ground level higher than the damp proof course?

    No, the outside ground level is the same as the garage inside ground level.

    Well that's not helping, I'd dig out 18inches or so deep next to the garage and fill with pea shingle as a soak away and see if things dry out. Is anything else in the garage damp, or just where you have shown?

    Screenshot_20190127-185907_Gallery.jpg No, it's just that one wall that's looking wet and that the puddles are gathering at.

    I dug out a trench this afternoon, how high should I fill it with shingle? Should I do anything else to prevent water ingress?

    Fill it to ground level. You could paint the wall and floor with a tanking solution to keep the damp at bay, they're very good products. Google KA tanking solution.

    Well I wouldn't have pebble dash down to soil level,I cut away 50mm or even 100mm from the bottom, to allow wall to dry out, then paint with a liquid dpm.
