The average annual rainfall on the Lower Mainland amounts to about 1500 millimetres or just shy of 60 inches. This abundance of moisture makes waterproofing in Vancouver, Coquitlam and other surrounding areas an absolute necessity. Water structurally damages more buildings every year than any other culprit, making it more ruinous than even fire. The average person may not suspect concrete as being permeable, but it is in fact a porous substance. The primary way to protect concrete structures is by applying waterproofing systems.
How water damages concrete
Concrete is a superior building material in many ways, but it has its shortcomings. One of these limitations rests in the fact that some of its common chemical components react to penetrating water. Depending on which aggregates are included in the concrete, the response varies. The two most damaging reactions are dissolution and expansion of key mineral components. These reactions can result in leaching or cracking in the cement paste. In either case, extensive damage to the concrete structure can result.
Another way water can harm concrete surfaces and structures is by penetrating to the reinforcing steel, that support concrete structures. When moisture and steel intersect, corrosion is often the result. As the rebar corrodes or expands, cracking and breakage within the concrete can occur making the entire structure highly unstable.
How waterproofing works
Polycrete Restoration’s area of expertise—waterproofing is often a critical aspect of concrete repair. Our Vancouver and Coquitlam clients trust us to not only mend their damaged or weakened concrete surfaces, but to fortify them. To this end, waterproofing is a critical component of many of the projects Polycrete undertakes.
Depending on the location of the surface—exterior or interior—the method of waterproofing will vary. Any of the following may be applied:
- Liquid applied epoxy or urethane membranes which are applied on to the surface
- Epoxy or urethane injection into the concrete cracks
- Combined systems which use both injection and surface applied techniques
- Hot applied rubber systems
- Torch on systems
Each of these applications is unique with various pros & cons. Our team of highly trained technicians are qualified to carefully assess and evaluate each project before moving forward with waterproofing. This ensures the superior results our clients have come to expect.
