Miyagi Construction is Metro Vancouver’s trusted specialist for post-tension cable repair in Burnaby. Our certified engineers and repair technicians handle the unique challenges of post-tensioned concrete structures found throughout Burnaby’s high-rise residential towers, commercial parkades, and mixed-use developments. We restore structural integrity safely, efficiently, and in compliance with BC Building Code standards.
Why Burnaby Structures Need Post-Tension Cable Repair
Burnaby is home to hundreds of post-tensioned concrete structures, particularly in the Metrotown, Brentwood, and Lougheed corridors where high-rise construction has surged over the past three decades. Post-tensioned slabs are valued for their long clear spans and reduced structural depth, but the cables that give these systems their strength are highly vulnerable to moisture-induced corrosion when protective grout or sheathing is compromised.
Corrosion of post-tension tendons is particularly dangerous because it can cause sudden, catastrophic cable failure with little visible warning. Burnaby’s wet climate accelerates corrosion wherever water penetrates failed waterproofing membranes or cracked concrete cover. Early detection and professional post-tension cable repair is critical to preventing structural emergencies and protecting occupants.
Our Post-Tension Cable Repair Process
Our post-tension repair program begins with a detailed engineering investigation including live-end inspection, core sampling over suspected tendon locations, and potential mapping to identify corrosion activity. All work is engineered and supervised by a licensed BC Professional Engineer to ensure structural calculations and repair methodologies meet BC Building Code and CPCI standards.
Repair work includes carefully exposing compromised tendons without severing live cables, assessing section loss, applying corrosion inhibitors, and re-grouting or replacing damaged tendon segments as required. Concrete is then restored using high-strength, shrinkage-compensated repair mortars, and the repaired area is coated with anti-carbonation coating to prevent recurrence.
Signs Your Burnaby Building Needs Post-Tension Cable Repair
- Rust staining or concrete spalling at cable anchorage locations
- Unusual cracking patterns following tendon paths in slabs or beams
- Concrete pop-outs or delamination above post-tension tendons
- Known water infiltration in areas above post-tensioned elements
- Engineer-identified corrosion during a routine structural inspection
