Brick Pointing Service
There is something about the stone and brick walls that simply captivates the beholder. These walls are the epitome of beauty and durability, and their value seems to grow with age. However, nothing lasts forever. With time, the bricks and their joints develop cracks and water starts permeating these cracks, stagnating there, while it slowly eats away at both the beauty and durability of the structure.
Moisture and temperature change are the biggest enemies of a building’s brick wall, causing damage to masonry and concrete. They have caused some of the most common problems that can result from harsh weather or improper use of materials or techniques in the original construction.
When these problems are ignored for too long, a fairly large section of the bricks may be affected. Over time, the mortar starts breaking down, and if left ignored, this can lead to a myriad of problems:
To counter all these consequences, it is very important to repair your building’s mortar joints well ahead of time. This is where our brick pointing services come in. Brick pointing is the professional work done by a brick contractor to repair or replace the mortar and mortar joints.
Repointing is the process of renewing the pointing, which is the external part of mortar joints. Repointing is also called pointing or pointing up, although both these terms are more closely related to the process of the finishing step in new construction.
The Process of Repointing Consists of the Following Steps
Examining the Structure
Before beginning the actual work, our contractors at MBH examine the masonry, mortar and techniques that were employed in the original construction process. We look into details and try to deduce where the true problem lies and what is causing the cracks or the damage. Usually, if the crack is smaller than 2mm and is not causing any major problems, we find it better to leave it as is and not repoint. Cracking along old repairs is common due to shrinkage of hard mortar and seasonal expansion and contraction along the joints.
Matching the material
We measure the strength and permeability of the original mortar and match it with the new. This ensures that we find the best match to the existing setup, as it is essential that the mortar used for repointing has performance characteristics similar to the original mortar that was used in the building. Some of these characteristics include permeability, compressive strength, and the degree of thermal expansion.
We also find the best match for the color of the mortar as well as the best match for the tooling.
Testing a Small Panel First
Before starting the work, all the methods and materials for the repointing will be applied in a test panel. A test panel is an area on the structure out of plain sight where the owner or conservator can test the methods that they will use for repointing, the color of the mortar, and the tools and skills of the mason. We believe this is crucial to foresee potential problems before going full-scale.
When to Avail of a Repointing Service
All kinds of masonry walls, be it brick, stone or block, are subject to gradual erosion due to rain, wind and wind-driven dust and grit. Once the exposed façade of the mortar has receded beyond the face of the outer wall, the joints become even more prone to erosion. This may allow water to penetrate and saturate the wall through the worn-out joints.
The decision to get a repoint done usually comes when you see one or more of the following signs of deterioration:
Every task calls for a precise decision, based on a wide range of factors. But our expert contractors as MBH Roofing and Waterproofing are experienced enough to predict potential problems at the outset and can thus prevent the repair or recovery task from becoming prohibitively expensive.
