hi...
my house is currently in midst of brick-laying...
completing soon by this week..
i have been to quite a number of houses (relatives and friends) and notice their walls have hairline cracks..
Besides weather conditions, what's other reasons that causes such cracks on the walls?
I have been to the site and notice that there are gaps between bricks that are not totally filled with cement...
I am assuming that they will be filled with plaster in time to come as i am having rendered walls...
Would these gaps be a factor in causing the hairline cracks?
Should i get them to make sure the gaps are all filled with cement or they do not really matter since they will be plastered?
Thanks....
