I noticed the other day that there are quite sizeable gaps in the mortar between the bricks at the bottom of the wall (see attached photo). Is this anything to worry about? Coud it be ants or some other insect? Thanks.
Hi baward, It looks very much as though the person mixing the mortar lost count of the number of shovels of sand. Try rubbing the mortar with your finger nail, if it loosens mortar then a weak mix is the issue. Raking out and repointing with the correct mortar mix is the solution. Regards S
Hi bayward, At the moment your image shows a stable wall and none of the bricks look like they have become loose. Just get it repointed - make sure the existing mortar is racked out to about 20mm and blown clean - and the problem will be solved. Regards S
