RE: tuckpointing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The mortar is probably a lime mortar which in some ways is superior to the modern Portland cement mortars.  It is flexible and will redistribute loads.  It does not require control joints.  When repointing do not use the hard Portland cement mortars.  Jimmy Price of Virginia Lime Works is an excellent source of information.

How does tuckpointing affect mortar tensile, compressive and shear strengths?  This is for 3-wythe brick walls in two separate buildings... one is about 80 years old, the other is 120 years old.  Any thoughts on mortar tensile, compressive and shear strength of these old buildings?
