Parging/pointing
Parging is basically a top-coat of mortar that’s applied over the walls of the foundation to shield it from the elements and provide a more aesthetically pleasing finish.
It is extremely important to use a professional masonry service on parging projects as a poor job can create a moisture trap that will lead to water damage. This can in turn compromise a section of your foundation, making your initial problem pale by comparison.
Stone foundations that are showing their age can be enhanced with a professionally applied coat of parging. It adds to the foundation’s water-resistance and prevents further mortar erosion. Masonry blocks can be unsightly and parging is also used to improve the look of an above-grade foundation. Parging hides a multitude of sins and gives the foundation a uniform and attractive new finish.
Pointing is the process of adding mortar to the gap in between the bricks. The issue today is that many companies do not know how to properly manage the upkeep of brickwork. Too often we are seeing companies use modern materials, such as cement to repair brick. The issue with this is not only cosmetic. Older brick homes were built so that the building could absorb moisture and then let it naturally dry out. This process has a large impact on the condition of the wall as well as its appearance. Incorrect Pointing can lead to water being trapped behind the dense mortar. This can then lead to leaks and physical damage to the stone, brick, and the integrity of your home! When the Pointing repair process is done correctly, it can assist in waterproofing as well as stabilizing the structure of the walls.
