How to keep the rain out !!!

[bob the builder 2]

Hi All

 

I know it has rained for the last month but i am really struggling to keep water out of my timber frame.

 

We have the windows in and roof dry / DCP attached under the VCL over the footings. Copious amounts of taping around windows and any loose elements of the VLC don't seem to be doing the trick.

 

It seems the water hitting the outside of the frame is getting under the sliver VCL and pooling on the concrete floor.

 

Any ideas on how to stem the tide greatly received.

We had this recently, I couldn't sleep. I could hear Kevin McCloud muttering about it! I only have timber roof  joists not timber frame, so I feel your pain.

 

The builder kept assuring me that it is ok, tanalised timber is often stored outside and will be resistant, and it would dry out ok once the roof covering is finished, and that does indeed seem to be happening.

 

Builder said we could hire scaffolding and cover every thing at great expense, so I got over myself and had to trust him.

Tantalised timber 😊

If the roof is waterproof, it sounds like something is not laid correctly. A bit of rain might penetrate gaps but shouldn’t be pooling inside! Photos might help.

I agree

Roof and windows in

there shouldn’t be any water getting in

another reason sheds/timber frames are an expensive option. Unless the plan is in tight to get fully water tight and bricked up externally in 4-6 weeks then the speed advantage of a shed build is wasted.

Thanks all

 

so speaking to the frame company they are saying the external membrane is not water proof and advised to get the cladding / brick on (not very helpful)

 

I wonder if there are any ideas about sealing the base of the frame to the concrete behind the DPC ?

 

Should i just put expanding foam or silicone ?

 

Thanks

I'd suggest they're talking b*****s. our TF was watertight once the roof and windows were in. we used black membrane and no water got in through it.

 

are you sure the water is coming through the membrane? could it be rolling down the membrane and then hitting the dpc and going in under the sole plate?

At the moment the frame is covered in a silver membrane - its peppered with staples. nails holding battens for the cladding etc etc

 

It seems the water is just getting in and running down to the bottom of the frame cassette and into the inside of the house.

 

We have lifted the silver membrane up at the bottom of the outside and placed a DCP under about 300mm and draped it out beyond the sole plate and onto the concrete footings (600mm in total) 

 

Rain has been bad but not feeling too confident to rely on the cladding / brickwork to solve this in the long term as any rain getting in in the future would be straight under the flooring / plasterboard.

 

thoughts / ideas welcome

I would be really surprised if it's going through staples and where the battens are attached as it didn't for us but I have been wrong many times before. it's not something stupid like the membrane lapped incorrectly? so the higher strip is behind the lower strip?
