I think the answer to your question depends where you are located combined with what are the traditional building methods of the area and available skill. In my part of the world, the San Francisco Bay Area, seeing brick buildings is unusual as it can be costly to make them seismically safe. If one happens to have a real brick wall or walls, it can be nice to expose and clean it to make it a feature as it is seen infrequently. Some of the brick construction here is done as a veneer over wood framing. If detailed property it can be convincing, if not, it can just look like it is a thin veneer just pasted on another wall. Seismic concerns aside, brick construction can be seen as durable and long lasting. The thickness and weight of brick adds to that perception.

I think this was just brick added to a wall so you should not need anything other than mortar but IMO this looks odd just put in the middle of a wall I would remove it

Hello there, It seems you're getting confused over choice of materials for your residential project. Let me clarify your doubts first , AAC blocks are available in longer dimensions only (26"x10"x8") which facilitates fast building in a short span of time . It is hence well suited for commercial and large residential projects as well. If you want to use AAC blocks, be sure that the labour have the knowledge of laying as it needs special thin mortar for joints. Else, the best option still working today is kiln bricks/ fly ash bricks, provided you get a quality consistent supply as they fluctuate by season.

Hello there, I would recommend you to check concrete bricks and Kiln Bricks both for quality first . Please check at least 3-5 brands of local manufacturers before buying. As for plaster cracks and water seepage, it depends on brick-brick joint which directly depends on concrete ratio. Keeping it steady will do that. You could apply water proofing compound (Dr. Fixit ) while preparing mortar. Regards, Aurum Ideas and Spaces Bhubaneswar
