A Complete Guide to Masonry and Brick Repair

Masonry is one of the most trusted construction methods used by industries. This method is typically considered safe and visually appealing for buildings.

Masonry in Wilmington NC, enhances the aesthetic appeal of the business and property, as it is fire-resistant, durable and lasts longer.  The limitations of using masonry techniques include cost, construction time, design limitations, weight, and environmental impact.

Masonry, Its Importance and Some Problems

Masonry is a construction technique that uses brick, stone and concrete on top of one another to build structures and walls. Mortar is an adhesive paste that is used to fill the gaps and to bind these materials together.

Masonry offers huge advantages because it is non-combustible, durable, resistant, has a longer lifespan and is attractive and elegant. It enhances the overall look of the building and also adds value to the property.

However, poor-quality masonry can create problems like cracks, damaged bricks, moisture buildup and rust on brickwork. If these issues are not repaired on time, they can damage the whole structure. A brick repair technique is used to restore structural stability, stop water penetration, and repair cracks.

Common Brick and Masonry Problems

Here are some common problems that a homeowner can face with the passage of time.

Structural Cracks

Cracks are one of the most common brick problems because they result from structural movement. Common types of cracks that usually appear are hairline, stair-step, horizontal and vertical cracks. These cracks usually require attention and timely repair, as they can damage the structure.

Mortar Deterioration

Mortar joint failure is the most common problem. It has a lifespan of 25-50 years. Signs that indicate mortar joint failure are crumbling or sandy mortar, receding joints, plant growth in joints and gaps between mortar and brick. The only method to repair these gaps is to refill them to a depth of 15-25 mm with fresh, color-matched mortar.

Water Infiltration

Water is the biggest enemy of the brickwork. It can enter the brickwork through gaps, cracks, above windows and doors and weep holes. To fix this problem and keep the water away from the walls, you should fill all the gaps and cracks correctly, improve grading to avoid water flow toward the wall and use a non-breathable coating.

Efflorescence

Efflorescence occurs when water dissolves salts within brick, mortar or substrate. When water evaporates, it leaves behind a white residue of salt crystals. This white residue is harmless, but the underlying cause can cause spalling and mortar deterioration.

Signs Your Home Needs Brick Repair

Here are some signs that may indicate your home needs brick repair:

• Mortar is crumbling or turning into powder.
• Gaps are formed between bricks.
• Cracks are running through the mortar joints.
• Dampness appears near external joints.
• Bricks are breaking.
• Wall looks uneven after heavy rain.

Common Masonry and Brick Repair Methods

Here are some brick repair methods that you can undertake before it starts damaging the structure:

Brickwork Repointing

Repointing involves removing the old, deteriorated mortar from the masonry joints and replacing it with new suitable mortar. It helps protect the edges of bricks and stones while improving the appearance of the wall. Minor surface cracks do not require repointing of the entire elevation. Common signs you should consider for repointing include crumbling or missing mortar, open gaps and water penetration.

Brick Replacement

Brick replacement is usually required when there is cracked or damaged brick, or when bricks become loose. When the damage to the brick is extensive, thorough evaluation is done before replacement to determine the cause.

Masonry Repairs

Reconstructed stone can develop cracking, surface loss and damage to the structure. The repair method depends on the type of stone, extent of corrosion, and the affected elements.

• Daily inspection for signs of pest infestation, plant growth and any environmental damage.
• Identifying and repairing brick damage to help protect masonry integrity.
