Block 'B' Cracks on the Terrace parapet wall

Hello Friends,
I had recently gone to the terrace (Block B) and i noticed that there are many cracks on the walls which needs to cemented as soon as possible. The cracks are noticeable in quite a number of places. We need to pressurize the builder to get this problem fixed. I also urge the members from Block A also to check their parapet walls as well.

Thanks
