Decking project - concrete problem

[Slicecbr]

Hi guys,

Hope everyone is well and safe.

I'm looking to put decking outside my conservatory and not sure whether I'll be attempting it or not yet but thought I'd clear the area ready.

I've cleared alot of concrete however come across this slither which runs partially next to the conservatory and side of the house. It has a top pour which was level with the pathway and a bottom part which is more blue/black in colour and alot harder. Is it okay to remove this totally or best to just take the top layer off?

As you can see from the picture I started to take the top layer off but thought I'd get some advise.

Any advise would be really appreciated. Thanks for the help

I cant see that being a problem unless you damage the masonry of the house.

You will obviously need to make space for the decking and frame so it will need to come out anyway won’t it?

You be ok as long as like PP says you don't start hacking away at the brick work. You going for Timber or composite decking. ? Decking one of my next tasks and i come to the conclusion that i going to spend a little more and get composite decking which i am going to lay on the concrete joists you use for block and beam flooring.

Thanks for the quick responses, much appreciated. Yes it would need to come out ideally, otherwise build the frame around it. I'm just wanting to make sure taking it out wouldnt cause damp or foundation issues. I've attached another picture.

Yes ideally I would like to finish it with a composite decking, I haven't confirmed a size yet so haven't calculated a potential cost yet

foundation issues

That meaty looking concrete could be the toe end of a raft foundation. Leave it well alone and build around it.

Why can't you deck over/around it, rather than mess about removing it?

Yes it seems like a strong, foundation type concrete. I'm just going to take the top off which is a different pour as I'm aiming for the decking to finish level with the concrete path.

A bit of an update...I've constructed the majority of the outer frame and have set the frame 10inch off the house currently - due to the sloping conservatory foundation.

As you can see from the pictures, I'll be able to get a 2x4 ledger board in until it reaches the end of the door and tie it into the existing frame.

However between the end of the door and the concrete path I'm working out how best to do it...my thoughts are:

• Leave as existing and just 'fly' the decking boards over the top at this section
• Attach a further 6x2 to the back of the existing frame to reduce the fly over to 8 inch in this section

Any thought on this would be great!

Thanks again

You could make a nice step that curves around the door in a half moon shape running just under the doors but over the sill. Do sort of the same thing to cover the slope and put planters on it.

Thanks for all the input on this. Just to show how it turned out I've attached some pictures. I ended up building around the concrete slab and flying the deck over it (around 6 inch gap). Thanks again
