Hello All,
We have had a flat roofed outbuilding(7.5m x 5m) built by a builder on building notices. I trusted that he and his men knew what they were doing. He called in a BC inspector for final sign off certificate last week. It failed on 2 items, one of them was the soakaway that I nor the inspector saw until it was all covered over. I dug down today briefly and found the 100mm plastic pipe about 125mm deep below the grass with 1cm dia stones scattered around and it was sloping upwards rather than with a fall downwards........ Not a good start! I didn't dig at the 5m end away from the building yet to find out what was there.
The soil is clay, so should it go to a soakaway firstly? If it can go to a soakaway, how deep should it be and is 5m away from the building and 2m from my boundary OK? Also should it go to a special receptacle at the end of 5m?
I think the water table is quite high as we are on flat ground 1km from the sea.
If a soakaway isn't allowed in clay where does the surface water have to go? Into the main drain?
Please advise anyone that can help.........
Thanks
Penny
PS the other failure by BC was the strength of the roof which is yet another thing to sort out! Should it be my problem or the builders to do?! We are still on good terms at the moment.....I think.
