Concrete and Brick Restoration
Quality Work Delivered On Time
Brick and concrete walls are designed to deflect most of the water that contacts the wall, but they naturally absorb moisture. While some water absorption is normal, significant moisture can
- Freeze / thaw damage
- Cracking and deteriorating at mortar joints
- Unforeseen degradation behind what is visible
Concrete is one of the most useful building materials, unique in how it provides structural strength, fire-resistance, and long-term durability in a cost-effective package. As buildings with concrete components age, they require inspection to identify and maintenance to repair any deterioration in their original design and envelope waterproofing.
Concerns with concrete walls typically focus on cracks and visible spalling (delamination). When concrete cracks, it’s often a result of the initial curing process (shrinkage) or caused by settlement in the months or years following. These cracks can allow moisture and water to enter the structure, causing damage. Most concrete buildings are built with a construction “cold joint” between the floors, and often these joints need to be sealed to maintain a waterproof envelope.
Additionally, since concrete is permeable, the natural process of moisture, air, and pollution moving through it can be a potential threat, affecting both the concrete and the reinforcing steel within, called “rebar.” As rebar rusts (oxidizes) it expands, cracking and weakening the concrete around it.
If enough deterioration occurs, it can affect the durability of the structure. The rusting rebar not only affects the steel but also weakens the structural strength of the concrete. Furthermore,
cracks in the concrete can cause spalling, where pieces of concrete break off, creating a safety hazard from falling debris
Our Restoration Methods
Sometimes the best coating for concrete and brick is one that appears to be no coating at all. Many coatings leave a film on the surface that can discolour, deteriorate, or even peel if not properly maintained. Recommended clear waterproofing sealers can protect surfaces and prevent water from moving through the exterior walls without changing the appearance of the surface. This protection can slow the rusting of metal reinforcement such as metal anchoring and rebar, help deflect water from the surface, and protect interior areas from water penetration.
Most waterproofing sealers penetrate deeply, providing invisible protection to the brick or concrete from within the surface. This reduces future maintenance, as there is no coating to fade, crack or peel, and retains the existing look of the building. Depending on the level of
exposure, a professionally applied penetrating sealer will provide surface protection for 5 to 15 years. Additionally, sealers may help maintain the appearance of your building by resisting mildew and moss formation and helping shed environmental contamination.
