Re: Repointing for 1890 historic home after Superstorm Sandy
I am working on a building along the coast and not more than 100 ft. from the harbor it is interior and below grade.
The Engeneer has specified the following mixture to be used.
1 cement " White cement "
1 lime " Type S "
7 to 9 sand
I had this mixture premixed just outside of Atlanta , GA.
The company was A. W. Cook
I used the following 1-1-8 this makes the sand fall in the middle of the required amount.
This mixture has not been tested under ASTM standards but my guesss is that it will reach 1800 PSI and higher.
The brick on this job are in the range of 5000 PSI & up.
Question did the Mason rake the joints to a depth of about 1 1/2 inch ?.
Also this Engeneer will not allow GROUT BAGS OR GROUT GUNS TO BE USED IT IS ALL HAND FILLED AND PACKED WITH POINTING TOOLS.
IF you find a mixture that you like A. W. Cook will blend it for you using this proceedure will require that you purchase the complete hopper which is 112 bags weight of 50 lbs ea.
cost should not exceed $1600.00.
