Concrete base shuttering

[simcfc73]

Morning,

Made a bit of a c**k up with my shed base.

It's at the side of my house with a boundary wall at the other side so th base was squeezed in.

I used wood on all sides and half way at its 6 meters so thought I'd put a expansion joint there.

Problem is I can't get the shuttering out. It's my fault as I over estimated the concrete and ended up pouring down the sides. Ive jackhammering the excess to try and pry it out but I can't shift the wood against the building. I've tried crowbars, drilling, bashing but it's splintering and not coming out.

If I can't get it all out in one piece will it affect the slab ( I did put dpm down). I've got some out, the middle section.

I would have thought that so long as the house DPC isn’t breached, you’d be ok?
You could try a carefully controlled gas torch to char and splinter the timber? Don’t heat the concrete.
Is there a Second DPC going in later?

I used leverage to remove shuttering , small hole in the top and 4x2 in the hole over a short pile of bricks as a lever point , lifted 4’x 4’ sheets of osb out easily .

Given a few years, it will rot away, if it's not causing any other issues?

Thanks for the replies. Getting them out is damaging the concrete so I'm going to just do the side against the building and then put my expansion joint in.

I've attached a picture... Not the best concrete level I know... Never again.

I agree with Harry. That wood will rot away pretty quickly, so if you've got a DPM in place, maybe just leave it be.

Quite typical down here, you can see the top of the OSB used to make movement joints that's left to rot away and fill with sand etc.
