Can you unload a column?
In those cases where the column deterioration is significant, unloading the column is usually required so that the entire cross section of the repaired column is capable of carrying the reintroduced design load. Without this unloading, the new repair will hardly carry any load. Drying shrinkage of new material may further reduce this share of load. Unfortunately, it can be difficult and expensive to unload columns, especially in high-rise buildings. If the existing load on a column is not removed before the repair, the jacket will only provide confinement to the existing column. The percentage of direct load taken by jacket will be very small (less than 25 percent of the jacket strength). If it is not possible to remove the load from the column, then a supplemental column system can provide an alternative method of support in combination with the repair of the existing column.

What can a restoration mason do?
A restoration mason can analyze old mortar and make a compatible mix, or you can send mortar samples to companies such as U.S. Heritage and get a custom blend with the same color and characteristics. You can choose between hydraulic lime, which comes in bags and hardens when it reacts with water, much like portland cement, and lime putty mortar, which comes in buckets and slowly hardens by reacting with carbon dioxide in the air.
Can You Mortar Over Old Mortar?
If your brick is 50 years old or less, you can probably repoint it safely with modern, portland cement–based mortar (although the guy doing the next repointing, who'll have to grind it out, may curse your decision). But if your house was built before World War II, the mortar is likely a mix of lime putty and sand, and you should try to match it. Otherwise, over time, as the soft old brick swells and shrinks against the rock-hard mortar, the bond between them will break, moisture will get trapped in the wall, and the brick faces will start popping off. Traditional lime mortar acts like a cushion, flexing with the brick's movement while allowing moisture to migrate easily out of the wall.
