The drain inspection chamber will need to remain in place, it’s 1500mm deep and on the main run servicing a row of several properties.
The concrete being poured. the sides of the trenches have collapsed slightly due to the soft ground, but this could have been far worse had it rained significantly.
The central area has been reduced and all soft ground removed to be filled back in with hardcore before concreting. The soft top soil can be seen on the right of the photo.
Just started digging, the house footings are about one metre deep, but the building inspector says we need to go to 1.3 m and widen the bottom of the trench to 600mm to account for the sandy soil.
Ironically, we will probably use several hundred pounds worth of sand on this job, but the stuff in the ground isn’t suitable. Never mind, we might strike gold on the next job!
First day on site – new orangery
The ground is looking very soft, top soil near the surface then sand. The machines should make short work of this though, access down the side of the house is good and we can use a grab lorry to remove the spoil.
Shane the digger driver makes it look easy!
Breaking out old foundations
The old conservatory has been removed and we’ve had to break through the old foundations to dig deeper. This will need to be approved by the building inspector.
Dunstable used to have a lot going for it, but now the only positive attribute that comes to mind is the fact that the ground is generally fairly solid and you don’t normally have to dig too deep!
On the whole, the old conservatory base was actually built fairly well, we’ve taken down a lot of old conservatories over the years and the foundations are often quite shocking.
