lack of mortar in brick wall


Postby wagon » Thu May 10, 2012 10:24 pm

The internal walls in my 1892 property are suffering from damp on removing the blown plaster most of the mortar is pure sand so just drops off. The wall an English garden bond lacks mortar in the header rows, so much so a tape can be inserted a good eight inches, I guess the tape only stops as the external wall is rendered. Please can you advise on the best approach for putting fresh mortar in the many holes and would a 3:1 mix be ok?
