ᐅ Should Brick Veneer Extend Beyond the Wall or Not? (With Illustration)

Hello everyone,

I have the following question:

Our site manager wants the brick veneer to extend slightly beyond the concrete slab to prevent water running down the brick from constantly keeping the concrete slab damp. (EXAMPLE 1)

Our architect, however, believes the brick veneer should be set back slightly because placing it flush with the edge of the slab can cause chipping. In this case, water would accumulate on the slab’s concrete. (EXAMPLE 2)
I have only sketched the essentials in the pictures, no membranes or similar.
What are your opinions or experiences on this?

My advice is: Don’t listen to either the site manager or the architect. Based on the plans shared here (even though they are not very detailed yet), I can already identify two significant thermal bridges....

I did some more research, this should be better, or do you still see thermal bridges?

Yes, it’s still not ideal.

A tip for planning the insulation of a building: draw a cross-section, take a pencil, and place it on the insulation. If you can draw a continuous line along the insulation all around the building without lifting the pencil, then you’re on the right track.........

But your architect should actually explain this to you and, above all, be able to plan it properly. The construction manager should also be involved.

Best regards

Hello E.Curb,

thank you for your answer.

Of course, I still need to ask this question to the architect, but right now I am very curious about how to connect the insulation under the waterproofing membrane (bituminous membrane) with the space between the facing and backing brickwork.

Best regards!

You need to insulate the foundation as thoroughly as possible.

However, I see a completely different issue: The detail should be designed so that the connection between the cladding / foundation / slab is interrupted, if you know what I mean...
