Cavity lean mix


Postby Dorset » Sun Apr 05, 2009 9:19 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
