Elevation Protection Options

[Rocks100]

Hi All, hoping for some advice on a potential job.

The rear elevation of this building has damp issues, the existing drain pipe looks to need replacing but the walls seem to be just soaking up moisture in numerous areas especially at the lower walls.

Reason I assume is that the stone work doesn’t seem to have any water resistant render and isn’t painted, so I’m just wondering what would people advise on the best option moving on forward, obviously need scaffold but would you say just a simple coupe layers of paint with a stabiliser solution would suffice?

A silicon render coat would probably be best solution but cost for that size of elevation would be huge so I think painting is the most viable option.

Many thanks in advance!

Hopper and pipe clear?
They fill up and get blocked with moss off the roof as thats what it looks like.

Yes agreed, that definitely needs doing but if scaffold on is going to go up is it worth painting at the same time, the entire elevation is quite damp, I don’t think the old cement render has any waterproofing in it, hence why I’m thinking is it worth applying a coat of stabiliser and painting a couple coats of weather shield…

Make or fit a rodding hole on ground and rod up for now.
Need a link?
I watch a drain guy that drills hole to rod down but you will be rodding up

What IS that growing on the vent brick?
Some sort of mushroom?

Would recommend you wait until spring or summer before painting that lot.

Indeed

Yes I think probably best, do you think just some anti fungal solution, stabiliser (maybe oil based) and 2 coats of paint would suffice?

Thanks!

Picture is grainy but that "mushroom" looks like a dry rot fruiting body to me. What does it look like close up and from above?

If it is dry rot, you have a major project on your hands.

Yes I think it does look like a dry fruiting body, but I thought that mainly grows on timber so surprised to see on the wall albeit in the vent.

What wound you suggest as best course of action? Check the area where the vent leads to I guess and see how far it has spread, would need fix the pipe and clear the hopper but the entire wall needs drying out throughly, hard to use heaters externally.

Any advice much appreciated.

Many thanks!

Dry rot, like any 'rot' can only colonise damp timber. The difference between dry rot and other rots is that it can ramble across or through other substrates to find more food.

What you have there may not be dry rot. It could well be some sort of bracket fungus.

Whatever you have indicates potential extensive decay of internal fimbers like floor joists. If it is dry rot and it has reached that stage, this is a major task. Let's hope it is not.

Do you see anything like cracking or shrinking of internal timbers near there? Springy floors? Mouldy mushroom smell?

Can you open up floor voids to check umderneath? Can you get a photo of the top of the fruiting body?

Perennially wet walls from failed guttering/downpipes is the classic way for these faults to manifest. If it is dry rot it will be an uninsured loss (bad maintenance) and will need urgent treatmemt - you should plan to be in it for tens of thousands of pounds.

So, let's hope it is a wet rot. Either way, you need to figure out what it is and the extent of the damage now. Dry rot moves very fast.
