Comprehensive Expertise

WSP's Building Sciences team has experience with all types of structural systems for balconies:

  • conventionally reinforced concrete
  • precast concrete
  • post-tensioned concrete
  • steel joist extensions, and
  • timber.

From decades of experience assessing and repairing balconies, we are familiar with the full range of deterioration mechanisms, including:

  • cracking of reinforced concrete
  • steel corrosion
  • concrete delamination or “spalling”
  • chloride contamination
  • carbonation
  • freeze-thaw damage
  • alkali aggregate reaction

We are also experienced in dealing with damage caused by deflection, thermal movements and structural distress and in evaluating balcony guards to ensure they comply with building codes and municipal by-laws.

We Specialize in Durable, Tailor-made Repairs

We provide repair and renewal strategies that appropriately address the balcony’s structural system, the existing conditions, and the owners’ short and long-term objectives.

In keeping with our focus on sustainability, it also means that often we can confidently recommend targeted repairs, corrosion control techniques and ongoing monitoring rather than wholesale balcony replacement.

We are Industry Leaders

For several decades, WSP has been at forefront of our industry.

In 1993, we were selected by the Canada Mortgage and Housing Corporation (CMHC) to author the seminal report: Concrete Carbonation in Canadian Buildings.

Similarly, when glass balcony guards at several downtown Toronto condominiums shattered in the summer of 2011, journalists, including those reporting for the CBC’s National News, looked to WSP to provide technical knowledge and insight. To help our clients manage their risks with glass balcony guards, we published a number of tip sheets and e-news.
