Charleston Masonry Repair matters for more than just the look of your building. Cracks and gaps in bricks and mortar weaken the structure and allow moisture to seep in.
A qualified mason can fix most masonry damage. However, ongoing maintenance, including waterproof caulking and regular inspections, is essential to extending the lifespan of these materials.
Masonry structures like brick chimneys, concrete basements, cement driveways, and stone pillars add both beauty and durability to homes, buildings, and other commercial spaces. However, unlike vinyl siding that can be replaced in the event of damage, masonry requires special care and attention to upkeep. This is especially true of the mortar that holds the bricks and stones together. Over time, the mortar joints can decay if not addressed. This can lead to deterioration of the bricks and even the structure itself. Repointing is a specialized task that involves the careful grinding away of old mortar and refilling the joints with new mortar to strengthen them. This process not only restores the appearance of a brick building but also protects it from further moisture damage.
There are a few key signs that your bricks and stone may need repointing. Bricks that appear loose or discolored are an indication that the mortar is deteriorating. Additionally, if you notice water leaking into the bricks and freezing, this is another sign of a failing mortar joint. While repointing can be a DIY project, it’s best to trust the professionals with this type of masonry repair.
The preparation for repointing is crucial to the success of the final results. It starts with a thorough inspection to determine the extent of the repointing needed. It also involves examining the structure for potential cracks and other damage. After this, the bricks and stones need to be cleaned thoroughly to remove any debris or dirt that might interfere with the mortar bonding process.
When repointing, the goal is to make the joints look natural and match the surrounding mortar in color and texture. This is why it’s so important to choose a mortar consistency that closely resembles the original mortar, and why it’s always a good idea to start with a small “test patch” before proceeding to larger areas.
Once the new mortar is mixed, it’s applied to the joints using a trowel to create a consistent thickness. It’s then wiped clean with a damp cloth to remove any excess. Once the repointing is complete, it’s often helpful to cover it with a thin layer of hessian to protect it during the winter months when freezing temperatures can cause the mortar to deteriorate faster.
Repairing Cracks
Masonry repair isn’t just about fixing gaps and cracks in brick walls, it can also help to restore structural integrity by replacing eroded or damaged brick or stone. Gaps in masonry can allow water to seep into the building which may cause damage to other materials on the interior and affect energy efficiency.
The first step in repairing cracks in masonry is to examine the crack and determine its severity and extent. Hairline cracks are generally cosmetic and do not need to be repaired, while larger cracks can indicate serious structural problems. Once the extent of the crack has been determined a commercial masonry service can then work to repair it.
This process involves cleaning the crack and removing any loose material with a wire brush. The crack should then be widened slightly using a cold chisel and hammer to create a greater surface area for the mortar to bond with. A skim coat of Earl’s 1kg Concremate Expanding Cement is then applied to the crack, allowing it to fill the majority of the gap and expand slightly as it sets. The resulting fill will match the surrounding mortar and will prevent further movement in the crack.
Cracks in masonry can be caused by many different factors including temperature changes, moisture and the natural aging of building materials. In general, cracks can be divided into three types – expansion, shrinkage and shear. Expansion cracks are often seen in brick buildings and are usually due to initial shrinkage of the materials followed by subsequent expansion. Shrinkage cracks are often seen in adobe and antique brick buildings and are normally caused by deteriorating materials. Shear cracks are the result of movement within the wall and can occur in both solid and cavity walls.
Removing Efflorescence
Masonry is a durable option for building construction, but it can be vulnerable to damage. Masonry repair and restoration projects can be time-consuming, costly, and complex. The difference between repair and restoration is important to understand for property owners. While repair projects are ideal for fixing small or moderate issues, larger-scale restoration is a great choice for older and historically significant masonry structures.
Efflorescence is a common problem that affects porous masonry surfaces. This white “salt-like” build-up occurs when moisture moves through the masonry, leaving behind crystalline salt deposits on the surface. It can be caused by a variety of factors, including weather conditions, temperature, and underlying soil conditions. For example, rain and snow can increase the amount of moisture in the surrounding environment and cause more moisture to migrate through the masonry walls. This migration of moisture causes a release of salts that can leave behind visible “whiskers.”
It’s important to remember that while efflorescence is unattractive, it is not harmful. Efflorescence is a natural part of the process that allows water to move within the masonry materials and evaporate. It is also a sign that the masonry is in contact with ground water that contains soluble salts. This can cause the water to rise through capillary action to the surface.
To remove efflorescence, a clean and dry sponge should be used to wipe away the white powdery substance. A stiff-bristle cleaning brush may be needed to scrub the brick surface. Then, a solution of water and vinegar should be applied to the bricks. This mixture has been shown to effectively dissolve the crystalline salts that create efflorescence.
It is also recommended that a clear waterproofing sealant be applied to the masonry after the efflorescence is removed. This will help prevent future occurrences of efflorescence and protect the masonry from further damage. It is important to note that it’s best to hire a professional to perform any masonry work on your home or business. These professionals will be able to properly diagnose any problems and recommend the appropriate solutions. They will also ensure that the repairs are period-appropriate to keep your masonry looking its best for years to come.
Replacement
Masonry structures are beautiful and add a sense of tradition and strength to homes, commercial buildings and historical landmarks. But they are also susceptible to natural wear-and-tear and structural damage over time. Often, these issues can be addressed with masonry repair services like repointing and crack repair, but sometimes more extensive repairs are required. In these situations, a reputable commercial masonry contractor can offer restoration services to make the building look as good as new while restoring its structural integrity.
The best time to perform a masonry repair is when the problem is just beginning to show signs of trouble. Taking steps to address minor problems immediately can prevent the problem from worsening and save money in the long run by keeping your masonry structure in tip-top shape. Common warning signs that it’s time for a masonry repair include crumbling mortar, gaps or cracks in the brickwork and visible differences between sections of the wall. In addition, it’s important to check for damaged expansion joints and shelf angles, which help keep brick walls stable as they shift and move over time.
It’s also a good idea to apply a water-based, penetrating sealer to the surface of any brickwork to protect it from rainwater and road salts. It can also help prevent efflorescence and slow the deterioration of mortar. In addition, regular cleaning of the masonry surface can help reduce dirt buildup and algae growth, which can further deteriorate the mortar and brickwork.
Brick and stone masonry is beautiful and durable, but it requires regular maintenance to keep its beauty and structural integrity. By understanding the difference between a masonry repair and restoration service, you can ensure that your home or commercial property’s masonry structures receive the proper care and treatment to extend their lifespan.
Masonry repair typically includes patching and plugging gaps and cracks in the mortar, as well as removing and replacing bricks or stones that have lost their structural integrity. In some cases, repointing may also be necessary to strengthen the bond between bricks. Masonry restoration, on the other hand, involves a more holistic approach that focuses on repairing and replacing all of the worn-out materials in the structure to restore it to its original condition. This may be necessary for older structures with historic significance or to preserve a masonry building’s value.
