Simba_ali Posted July 29, 2020 Share Posted July 29, 2020 Hey I've got an ongoing thread in the roofing section in relation to a balcony leak but I think this question may be better suited here. I know I have a leak on the roof upstand but I'm trying to establish if water penetration through the brick wall could also be a factor I've taken some pictures as I've noticed missing mortar in certain parts of the brickwork. I can't tell you whether they have appeared over time or if they were there when I purchased the house (new build 3 years old) How serious does they look for the overall quality of the mortar and the water penetration issue? Can these areas be patched up? Many thanks Link to comment Share on other sites More sharing options...

tonyshouse Posted September 19, 2020 Share Posted September 19, 2020 Poorly rubbed up brickwork typical of stubbiest on a price unlikely to leak none the less to eliminate water penetration I a fix a sheet of poly over the brick wall in question I often find flashings leak in or junctions between bricks and balcony waterproof layer.

scottishjohn Posted September 20, 2020 Share Posted September 20, 2020 (edited) if thats what you can see --how bad is it where you can,t see? that would be my question rake out and repoint? Edited September 20, 2020 by scottishjohn Link to comment Share on other sites More sharing options...
tonyshouse Posted September 20, 2020 Share Posted September 20, 2020 No need to repoint, possible touching in locally with colour matched mortar, not for me yet 25 yrs time may be. Link to comment Share on other sites More sharing options...
Mr Punter Posted September 20, 2020 Share Posted September 20, 2020 I would tap around the crappy looking bits with the corner of a bolster and see what falls out, then fill in with a matching mortar. Unless you get driving rain against this wall it is unlikely to cause issues. The bricks do not look porous. 1 Link to comment Share on other sites More sharing options...
Simba_ali Posted October 3, 2020 Author Share Posted October 3, 2020 Thanks for the replies. Its a new build about 4 years old. Not one of the bigger developers but still a typical cheap new build from my experience. What i can't tell is if this is just bad brickwork and has been like this from day one or if its getting worse. I've also notice small holes on the vertical joints on one edge of the brick. I will try and upload some pics soon thats shows this. It rarely gets driving rain but when it does, the wall seems to dry out very quickly. What is also strange is the bottom half of the wall is of much better quality than the top half and has none of these problems. Its like 2 different people did the work!

Its like 2 different people did the work! Quite possibly. The new bungalow next to us has a half hipped wall facing us which had the walls bricked up to eaves height by one set of brickies and the bit above was done much later by different brickies. The bit above has different coloured mortar which hasn't been cleaned off the bricks as well as lower down. Does not look tidy. Link to comment Share on other sites More sharing options...
PeterW Posted October 4, 2020 Share Posted October 4, 2020 Modern estates use teams of brickies - it’s not unusual to see different mortar beds, bonds etc as you move up a building. It is also why when you have two working together that haven’t before, only one does the setup of the corners unless they are using profiles. 1 Link to comment Share on other sites More sharing options...
Declan52 Posted October 4, 2020 Share Posted October 4, 2020 The team that built the bottom half probably asked for more money as they where worth it and the boss went no and got someone cheaper in. Link to comment Share on other sites More sharing options...
Simba_ali Posted October 4, 2020 Author Share Posted October 4, 2020 (edited) Hey i managed to get a photo of the strange holes appearing. Any idea why this could be happening? At the moment there seems to be about 5 of these all around one area but one or two in totally different areas. The hole is around 1cm - 1.5 cm deep and then i hit something solid which im guessing is mortar Regards Edited October 4, 2020 by Simba_ali Link to comment Share on other sites More sharing options...
Declan52 Posted October 4, 2020 Share Posted October 4, 2020 Line pin holes maybe. 1 Link to comment Share on other sites More sharing options...
Simba_ali Posted October 4, 2020 Author Share Posted October 4, 2020 sorry whats a line pin hole? I'm a novice when it comes to brick work etc Link to comment Share on other sites More sharing options...
Declan52 Posted October 4, 2020 Share Posted October 4, 2020 The brickies would use them to build to a line. You have one pin at each side of the wall and the line is tied to the pins. https://www.toolstation.com/line-pins/p85832 Link to comment Share on other sites More sharing options...
Simba_ali Posted October 4, 2020 Author Share Posted October 4, 2020 ah ok i understand, thanks for explaining that for me. here is another photo showing the area they are concentrated in.. I'm considering contacting the new build warranty provider as my first thought was that this is weak mortar and is showing considerable weathering for only 4 years old. This wall is 3 stories high and does get pretty soaked during the winter but none of the other walls are showing this amount of wear. Ive also heard these holes could be frost damage? but in all honesty i have no idea. Does this look like its bad enough to need repointing? providing the mortar is sound obviously Link to comment Share on other sites More sharing options...
Declan52 Posted October 4, 2020 Share Posted October 4, 2020 Is this at one side or in the middle of the wall. Link to comment Share on other sites More sharing options...
Simba_ali Posted October 4, 2020 Author Share Posted October 4, 2020 Those holes are located where the red circle is in the photo. the entire wall is about 4 meters long and you have about 1.5 m on each side on the door roughly.. Link to comment Share on other sites More sharing options...
Mr Punter Posted October 4, 2020 Share Posted October 4, 2020 The site bricklayers we have had can be fairly rough, but they have a service person that acid treats and jetwashes the job and fills in missing mortar pointing. Link to comment Share on other sites More sharing options...

This looks like different bricks were used when they go 7 courses from the top of the door. Different mortar mix too. Did you by off plan or was the house complete when you saw it?

Simba_ali Posted October 4, 2020 Author Share Posted October 4, 2020 (edited) It is a share buy property through a housing association which i visited once prior to completion. I am passed the 2 year builders warranty but can still claim on the structual side of the warranty. it might be worth mentioning rain has been battering this wall for 2 days straight so the top of the wall is drenched and the bottom half seems drier Edited October 4, 2020 by Simba_ali Link to comment Share on other sites More sharing options...
Mr Punter Posted October 4, 2020 Share Posted October 4, 2020 I don't think you have much of a case as you have left it so long but you may manage to get them to send someone to touch in the pointing for an hour or so just as a goodwill thing.

Simba_ali Posted October 4, 2020 Author Share Posted October 4, 2020 Yea it's abit annoying but I didn't even think to inspect brickwork mortar... Do you think from the looks of it that it just needs repointing? Not tearing down the wall or anything? Link to comment Share on other sites More sharing options...
PeterW Posted October 4, 2020 Share Posted October 4, 2020 It’s pin marks by the looks of it - where in the UK is it as that mortar is very coarse ..? Would only take an hour as @Mr Punter said to touch that lot in Link to comment Share on other sites More sharing options...

Brickie Posted October 6, 2020 Share Posted October 6, 2020 Looks like a non-porous,engineering style brick. I’d bet @Nickfromwales’s sheepskin sombrero that there was staining as it was built,and the contractor went crazy with the jet wash & brick acid at handover. You’re not supposed to hold the jet wash too close or for too long in one area because it’s detrimental to the joints,but the temptation is often too great.
