Uncalabrated slate paving - Nightmare to lay

Paving expert · Thu Jul 16, 2015 11:06 pm

hi there tony I've recently layed a patio with unacalabrated 600x600 slate slabs but had nothing but problems as the varieation in thickness just in one slab could vary from 10 - 40m I layed them on a strong sharp sand and cement mix (wet) as I don't like doing dot and dab as you get voids under the slabs .and I've had to to back a few times to sort some rocking ones just wondering if you have any advise as I don't usually have any problems with rocking slabs useing this mix
