Advice on external works

[Taff]

Morning, 

 

looking for advice on materials to use for the driveway and around the house.

 

currently the driveway has hardcore however this has been mixed up with mud etc during the build so I’m looking to scrape that away and put another substance down again temporary just so we are not traping mud everywhere also don’t want to waste money so this would form part of the driveway etc. This will eventually be covered with gravel. 

Around the house, I’ve Doug a trench out and want to fill this in with something hopefully the same stuff as the drive. Will be putting some damp proofing around the house foundations prior to filling in and then installing ACO. Drainage.

 

Ive had a look and there seems to be lots of options. The site is quite wet at the moment so not sure what material would be best. (Grano dust, type 1, type 2, ballast etc).

 

any advice would be appreciated thanks ?
