Its quite frustrating for those of us who are trying to ensure your garage doesn't get damp when what you are proposing is still gonna allow damp in, you really don't want that to happen, trust me, you don't, it's not just about the walls being damp but everything inside will suffer too.

If you are really, really against having anything covering the inside of the blocks then you need to do something outside instead to prevent damp coming in permanently, its either membrane inside or outside, but it needs it in one of the places.

Personally I'd rather have it inside, stuck in place with a waterproof adhesive, and then covered, maybe some sort of rubberise flooring material placed on the wall would look better but also ensure that when opening the car door etc it wouldn't get 'chipped' on the wall?

I fear if you don't do this then in future you're gonna have to do something to stop the damp anyway, so better to get it resolved once and for all now.
I have to agree, you need to be confident about it now because it will be a right pita afterward s. I spent a lot of time and money on drainage and I now get no standing water. Sue of course queries it because she can't see the problem any more :banghead:

I am going to get some of that tanking stuff for the outside walls and maybe do the inside too, good thick 11 inch walls, 2 walls at the rear wall with a small cavity free draining gravel infill, drive water slopes away from the garage now builder has resurfaced it.

Also there is enough width on the foundations inside to build another wall at the rear and part way down the sides with a good cavity, maybe all the way yet down the sides so that would be an option as well. I have tried to think it through and if a problem arises then look at it.

I am of the traditional building mentality, see what you’ve got and what is happening then look at solutions.

Hardcore here today and concrete floor Monday.

I am a traditionalist when it comes to building and love all types of old buildings and the way they are constructed. Our house is 1891 with no foundations as such and built with lime mortar,

I did consider getting the foundations dug out and a rubble/gravel lime mortar infill foundation but I’m not well enough after my injury to do any work myself.

Building partially underground no dpc using cement/ concrete is asking for problems. I have thought about lots of options, just having a parking area with no timber garage on top.

I need to look at drainage too. I have thought about tanking also.

I am considering the idea of building an inner wall of reclaimed brick using just lime mortar, this wall will get wet from the concrete/cement wall behind but the damp should “wick away” with ventilation and dry out, just as it’s designed to do.

Need to make sure if I go with my plan there is enough room to get the van in, problem is the total width allowed was 3.6 metres but for strength the builder has laid the blocks on their sides, so much thicker and stronger, so lost some width there, although once through the entrance the garage will widen out when the timber bit starts.

Decisions decisions.

I'd definitely have an aco drain all the way around the outside. I did ask before but didn't get a clear answer. What sort of timber work do you want, oak framed, tanalised soft wood, shiplap, tounge and groove?

Sorry I missed where you said that, what’s an avowed drain? I will have a google I have seen the field drains?

It will be seasoned timber they make a lot of industrial buildings the place I would be getting it from, farming buildings etc

It’s all finished ready for the timber Motorhome garage to go on, end of June.

Trenches filled with Geocell glass foam wrapped in Geocell membrane, drainage in

Rear wall is double skin concrete block, concrete blocks laid on their side for strength.
Too many photos have loaded not sure what happened there.

8.9 metre long, door height 3.25 metres,

Ventilation!!
My only car that rusted was the one I garaged !!
I put a 2” gap all the way round the roof of our wood store which dries it perfectly.
Same applies to Vehicles.
Your garage looks good.
Well done.
Mitch.

A few photos.

The van goes in a treat I have made a workshop at the rear as nearly 2.5 metres spare. I’ve used reclaimed bricks and lime mortar for the work area so any moisture should wick away from the double glazed opening windows.

Need some paint now coming on Thursday.

I’m confident no damp in winter the side and rear trenches are back filled with geocell glass foam which is load bearing, insulating and moisture goes straight through it. Plus the lime mortar inner walls should let damp absorb then release should there be any.

I'll go along with keeping soil off the brickwork, dpm, but I'd be wanting to know what the natural water table is, the last thing you want is a fancy land drain that encourages water, make sure there is a good soakaway, but I'll go along with others, the builder should've given you a spec sheet when pricing.
