So as this is private sewer to back of my house and I don't need a build over agreement, do I need to inform thames water of how the new layout is of the drainage, provide anyone with a drawing etc?

Ok well the bottom of the trench is probably not done yet for the drainage. I have the foundations laid only yet around the side of extension

So your not talking about the the top part of the foundation where the dpc level is, your talking about the bottom of the foundation at the Base, say if it was 1 metre down... that has to be lower than the invert level So to clarify the top of the foundation level (where the bricks would be...

When you say the foundations have to be 150mm lower than the invert level, I don't think this is the case for me. The builder who i sacked now has made the foundation sit higher than the invert level what can I do to overcome this?

so your saying the sewer drain is straight onto the rodding access at back of garden, which is how it will be. But it will connections bending off into other rooms for the bathroom and kitchen, is this ok? the other issue is the drainage runs further as its coming from the garage room, so in...

if i build over a private drain with a extension in the back running 10m in length. is this ok? i will have a rodding access at the back of the garden. in the extension will be new connection for bathroom/kitchen. the groundwork builder doing it will design it, but it hasnt been designed by...

I had full planning for a side extension, we dug footings, put the steel and knocked main side wall out. Due to problems we now want to stop and put the original wall back to how it originally was in first place. Building control have signed footings and steel off already, can we just simply go...

Is the block and beam allowed to sit on a single engineering brick as below. Its only resting on 1 brick faced upside down, which is underneath a 800mm concrete footing. Would BC pass this?

I removed parquet flooring in a bungalow and the concrete is covered in bitumen. A little thick in some places. I want to lay ufh matts and install ufh. How do I tackle the bitumen. Is it acting as a dpc? I don't want the place smelling with the ufh

I'm putting ufh matt on top of the lifted floor which has a bitumen layer in, if anyone knows?

I've removed a old parquet flooring which was glued down with bitumen. I want to install ufh over the top, what's best way to do this over a floor that was previously glued with bitumen?

I'm being advised by builder not to use laminate and to go with engineered over the ufh boards. He said laminate will cause issues down the line. My preference is laminate due to costs but I dnt want to run into any issues.

Ok I may just leave the underlay alone and do direct on top

Ok thnx. It's a bit confusing because when I'm looking at eps boards it saying check to see which underlay is recommended for laminate or engineered. But from what yr saying no underlay is required and the laminate can sit directly ontop of eps without underlay

Can laminate flooring be installed the same way directly onto the boards or would it need a underlay with it on top of the eps board? I'm also wondering if any screeding needs to be done on top of the boards and pipe first?

Which overlay can I use around the whole bungalow over concrete for this purpose?

I'm mixing a new extension with the existing house. The old part of house is just a concrete slab no insulation. I need to build this height up by 25mm overlay boards for ufh to match the new extension. Can I just put 25mm ufh overlay boards straight over the concrete, then lay a floating...

Yes it's already installed

Can you lay blockwork on top of block and beam floor to create a wall partition, they will not be load bearing just on single storey with flat roof aboce. I want to subdivided the floor area into 3 separate rooms.

This is all that's been done on the floor level, and work was halted since. Could the gap cause a issue with the planners up to the boundary, as it tapers in towards the end. The neighbour has no issues with me putting up a single storey this close.
