Create slope up to road

[mattbdavis]

Hi, I can’t seem to find an exact answer to my question so hope you or others can help. I currently have a straight drop of 500mm from the road into my front garden and need to create a 10m slope down to the front of my house to lay block paving on. I realize I will need a 150mm standard sub base of type 1 but what would you suggest to create the slope below this?

I am awash with concrete as I have removed a garage base and concrete drive from the rear of the house and also a vast amount of bricks and blocks from the house renovation and ex garage. I was hoping to recycle this and I am prepared to hire a concrete crusher to create the type 1 sub base. Could this also be used to create the entire slope below?

Also I have some clayey soil I have excavated but assume it would not be a good idea to use this?

FYI the front garden is currently grass growing in flat clayey sub soil and I will have drainage along the bottom of the slope to a soak away

All advice much appreciated and apologies if this has been covered before.

Regards

Matt.

you can use your hardcore thats been crushed matt
just build it up in 100mm layers rolled rather than wacked if possible
compaction is the key in this

Wow, amazing quick reply LLL, a big thanks.

Would I need to crush all to type 1? And would that be a vibrating roller to use?

Also I take it i'd need retaining walls to each side?

Thanks,

Matt.

yes you would either need a retaining wall or kerb at each side
this detail would have to be built first
and sorry of course a vibrating roller

Thanks for your replies LLL, Just a couple of clarifications and I think i'm ready to start.
Will all the hardcore need to be crushed to type 1? and is brick ok to crush with the concrete?


Much appreciated,

Matt
