Hi,
It’s been something I have been meaning to start for a very long time and finally we are starting our home cinema project, equipment updates as we go but opted for atmos 7.1.4 but will future proof for 7.2.4 and possible more.

Anyway before we get to the interesting stuff it’s a lot of mud and waterproofing.

i will start with the before pics.

Be very very very very careful "waterproofing" if it's an old house (more than 50 years).

I could quite literally write a book on heritage building damp treatment and you will 99.99% guarantee to have massive problems if you've taken your advice from anyone other than a heritage building damp specialist. Note 99% of damp companies are charlatans and thieves and don't know what they're talking about even if they claim to.

On the other hand, if not just ignore me and good luck. This is exactly what I've just done so I feel your pain just starting having just finished mine.

Hi,
Thanks for the advice, we are using a very large and reputable company who deal with a lot of heritage properties so hopefully we are good but it is a minefield for sure.

p.s it is a very old property.

FWIW

I went through 6 damp companies before I found one that had even the faintest idea including some big reputable companies who claimed experience in heritage damp issues. If they are recommending one or more of

1. Concrete Tanking (or concrete of any type for any use)
2. Damp proof injection course
3. Paint/plastic treatments to "seal" the walls

Then I would be very wary of the advice or the work as none of those should be anywhere near an old building.

A caveat is of course I have no idea what you have or what they've recommended (neither is it any of my business of course!) but it cost me the best part of £30k to rectify the work a bad damp company had done before we bought the house. It is also likely to look fine for a year or two and then you'll have to spend £1000's fixing the problems

Thank you.

Just to add to this topic and what we are actually doing, and yes it’s expensive:

Cavity drained membrane drilled to the walls on floors
Channels around room for water to go into
dual pumps and battery backup and alarm
This will then be covered in plasterboard dot and dab and flooring

I have been thinking about converting my basement to an AV room for a while: and it looks very similar to yours.

not sure the mrs will ever let me, but I can watch your project develop and dream!!!! 😊

Luckily mine wasn't damp enough to need all that (i.e. we don't have pooling or running water) but yes I can imagine that not being very cheap to do if you're getting an external company in to do it.

We are carrying out the 2nd fix of a clients basement cinema in 2 weeks time. We have already soundproofed and wired. We’ve worked on many basement cinemas and they are fantastic spaces.
