oil tank installation help required

thehairybuilder

We`er about to install a new bunded oil tank in the garden but wondered if there is any recommendation as to how thick the concrete base should be and how ddeep we need to bury the copper pipe from tank to the house .
Any ideas anyone ?

Any help appreciated as always
Thanks

Bump for you

I guess it may depend on how big the tank is and whether the weight is spread or whether there are only a few contact points with the base

Mine is a 2000 litre tank and the base is about 10 inches thick but I really have no idea if that was engineered or just guess work

Ours will be an 1800lt tank and I`ve discovered that base should be at least 50mm thick and extend beyond widest part of tank by at least 300mm all way round .
To be safe I`m going to make mine 300mm deep as 50mm seems pretty flimsy and no-one seems to know how deep pipe should be so I`ll put it at 300mm deep also to keep things simple .

I believe that it's supposed to be buried 24inches (60cm) belw ground.

Mine ended up abut 20 inches as it's a lot of soil to dig!

Oh - d while I remember it should be laid in sharp sand and ideally something laid over it to protect it e.g. tanalised timber laths or tiles. (It is plastic covered copper pipe I trust!)

The usual method seems to be to use a few paving slabs bedded on concrete. The concrete is mixed and laid dry as moisture from the soil will cure it. On ours there is about 50mm thickness of concrete.

Better safe than sorry

Imagine 2000 litres of oil falling over
