concrete bleed water/brick permeability

[Subject Prev][Subject Next][Thread Prev][Thread Next]
As part of a retrofit project, a new concrete wall will be cast adjacent to an existing unreinforced brick wall.  The architect is concerned about water bleeding from the fresh concrete, migrating through the brick, and damaging stone cladding on the other side of the brick wall.  They have proposed a fairly expensive waterproofing system for the brick to prevent any water damage.

Can anyone suggest some references for determining the quantity of water that may bleed out of the concrete and migrate through the brick?  Also, any recommendations for an inexpensive sealer that would do the trick?

Thanks.

Jason Emoto
