I need to estimate materials for laying a patio and building various walls. It's been suggested I buy limestone for bedding in the patio slabs and I estimate I'll need one cubic metre for this.
For the foundations - what quantities of what should be used? I'd prefer to use the combined aggregate but I have an eye on cost, would it be cheaper to use a mix of limestone instead of sharp sand? What's recommended - and in what mix?
I estimate the area for foundations for the walls at .60 cu metres
I've estimated the number of bricks I'll need for the walls which total approx 14.5 sq metres, but how do I estimate the amount of mortar needed and what mix is used in mortar? I will also need to grout the slabs once laid and the total area involved is approx 120 sq metres.
Finally, can someone tell me how many wall ties are recommended to use in a double thickness wall?
