Simple raft foundation

[fiaraziqbal]

Good morning all,

 

I have a few questions regarding a raft foundation.

 

I am building a temporary structure in the fom of a mobile home whilst i get the main construction underway.

 

The site is exposed and in the windiest area in Europe as such instad of piers i decided on a raft foundation.

 

it is a 3.6m by 12 m raft andin my head a simple 100mm concrete slab would do.  It will sit on glacial til so the need for hardcore may not be needed.

 

So to my questions.

 

1) What alterations to the simple slab would you make?

 

2) the top soil has poor drainage, i was thinking of placing a simple draininage trench on two sides to drain away the water prior to laying the slab.

 

If you have any links to documentation, videos or advice that would be great.

 

Regards

You may find it easier to dug the drainage out after the slab is cast.

Concrete in some metal rings so you can strap down the mobile home to stop it blowing over.

I was more concerened with the leveled area becoming very wet or even standing water.  I was givingthought. to digging a few feet down next to teh location of the slab and usiing a pump.
