Cavity lean mix

by Dorset » Sun Apr 05, 2009 10:19 am

Hi,

I have to put a lean mix into the bottom of the cavity 225mm below DPC.

I am unsure on what a lean mix is. is it sand and cement or ballast and cement and what ratios are used.

Your help once again is mucho appreciated

Hi

When ordering ask for concreting ballast.

A lean mix is a dry weak mix

Bye
