what is the minimum thickness you can use for a solid concrete slab floor. I was hoping to get away with 75mm? Many thanks

Yes I did. Just really hoping not to dig that deep. Thanks

I posted a topic earlier after talking with a BCO on the phone. I explained I have a tree 2 meters away from my foundations (after setting out it is actually 4 meters away). He advised I would have to dig 2.1 meters deep which I found very daunting. He would not advise me on how much of the rear...

I am digging my foundations where there is a previous drain which was used for rain water that I assume must connect to my main drain. Will it be ok to remove what is in the way and cap it as I will have to use soakaways? I found it blocked but have dug down/ cleared it. What method is best to...

Thanks for that information Ronny. What do you mean by clay master?

Hi I am not sure if it's shrinkable clay? It is on a slight slope though! I am very worried about going that deep. I take it ply wood with mini acros will be ok to support the excavation ?

Thanks for that Frank. I had a chat with the building inspector- he now wants me to got 2.1 meters deep as I have a blossom tree near me. Seems too much? I take it the foundation blocks are the thickness of 2 blocks + cavity. ?

I had a brief chat with a building inspector who advised me that the area where I live the normal foundation depth is 1 Meter. Is this the actual depth of concrete of just excavation depth? Thanks[/list]

Yes I will be going deeper that his foundations. He has a garage on the side, I will be digging 1 Meter away from that. He if a very miserable old man who enjoys complaining. I am tempted to excavate everything up to 3 meters away and then just excavate near him at the last chance and fill with...

Hi, I've served a Party Wall Notice on my neighbour (regarding excavation within 3 metres) and he does not agree. What are the implications if I were to go ahead and commence work anyway, rather than go down the route of instructing surveyors and having a Party Wall Award drawn up? Thanks in...

Thanks, that's what I thought. And medium density 3n concrete blocks / engineering bricks ok?

Would anyone be able to advise me whether it's best to use sharp sand 4:1 mix or building sand 4:1 mix for up to damp course. I'll be laying medium density concrete blocks/ engineering bricks. Many thanks

I am in the process of putting down my foundations and would like some advise on laying the slab. I am using 150mm of type 1, 50 mm sand, membrane then 100mm of concrete, 100 mm of insulation then around 60mm of screed. When laying the 100mm of concrete would you advise building the damp course...
