Tanking a cellaris there a rule of thumb to guesstimate the cost?

Yeh its dead easy. It will cost twice what the estimate is & four time what you can afford

Well, there's the size, depth and tanking method to consider - but given those variables, I'd say anything between £600 and £12,000.
That help?

with deep preperation a fair bit per square metre
get at least 3 quotes (5 is good )
go for trustable and mid price imho

I was hoping for the '£400' square metre as for extensions, or what ever it is.
More details 4m x 4m, 6ft deep (about 4.5 ft below ground), brick walls, stone floor. No water ingress just damp stone and brick up to 6" off the floor. Very humid though but reasonable ventilation keeps it useable for storage and DIY stuff. I deally would like to dig down about a foot to give more headroom and have it dry and cool for a larder/meat store etc.
Just pondering as we're thinking of getting an extension off the back and this would seem to be an ideal time to get it done. Damn site cheaper than moving.

I’ve got a mate who’s been looking into it (probably lives close to you in W. Yorks). He’s got a terraced back-to back and has been quoted £7,000.
Apparently, straightforward tanking isn’t done now- if there’s any movement then the tank will crack and the whole job is ruined. So I think now they spray on a semi permeable barrier which is flexible, then install a sump & pump below the floor to pump out water that has collected.
I expect the sump/pump bit wouldnt be needed if you've just got a vague dampness- probably get away with a flexible membrane.

Funnily enough we are considering exactly the same thing at the moment - However we need to raise the patios (we've 3!!!) up to the same height as the house ('bout 6-8ft)and are thinking about putting in a tanked cavity underneath the patio's to replace the shed space currently taken up down at the bottom of the garden (then that space will become chickenopolis )

That's about it, though in my case I suspect the damp is solely from the floor sooooo I'm toying with idea of digging out the floor and laying memebrane and concrete, opportunity to lower the floor as well subject to the usual footings issues, then line the walls with a semistructural membrane that you can plaster or tile over. As we're on the top of a hill and the cellar is not toatally below ground the full scale tanking is probably not necessary.
Can anybody suggest a name for the semistructural membrane. it comes in rolls about a metre wide and has 'corrugations' on one side.
Cheers.

Can you explain what this tank thing actually is?

Not any more, but it used to be that as long as the stick was thinner than your thumb... hence the "rule of thumb".

like the oldroyd series? SafeGuard chemicals do something like this where the dimples on one side leave an air gap and you can plaster directly over the top - looked into it a couple of years back for our place, several different variations but din't get as far as pricing it up.
Sorry if quote dun't work, numpty here!

Thanks that looks something like it. THe whole idea may be redundant as OH thinks we should move to the Forest of Dean or thereabouts.

Do YW have many offices there?

No, it would involve change, not something I'm comfortable with but property is cheaper than here and there's the opportunity of a bit of space for veg plot etc.

Well, he's eaten pretty much everything else around him by the looks of things.

You think he's becoming a nutritional refugee? Eaten everything with calorific value within 100 miles, so having to move?

sorry to interrupt - but to answer the Q, it describes a way of waterproofing a cellar (or other very damp room) by lining it with what is in effect a waterproof box (or the bottom half thereof). There are a variety of proprietary systems .

TankingDid you get anywhere with this Behemoth? We've got 2 large coalholes/underground sheds I'd like to make waterproof for putting bikes/roofboxes etc in and this would seem to be the way to do it.
Any recommendations?

No - all house plans have changed - we're moving on so don't need the extra space.
