Why Skipping Shoring is the Biggest Mistake in Construction Today
Shoring isn’t just a safety measure—it’s a structural necessity. In modern construction, especially in urban environments like Toronto and the GTA, the risks of trench collapse, structural instability, and regulatory penalties are too high to ignore. Yet some contractors still underestimate the value of proper shoring. In this article, we explore why skipping shoring is one of the costliest and most dangerous mistakes in today’s construction landscape.
1. What is Shoring?
Shoring refers to the use of temporary support structures to prevent soil movement or collapse during excavation or construction. Common types include:
- Hydraulic shoring
- Timber shoring
- Sheet piling
- Aluminum hydraulic supports
Each method is suited for specific soil conditions, depths, and structural needs.
2. The Dangers of Skipping Shoring
3. Legal and Regulatory Requirements
In Ontario, the Occupational Health and Safety Act (OHSA) mandates:
- Shoring or sloping for excavations deeper than 1.2 meters (4 feet)
- Engineer-designed systems for deeper or unstable sites
- Regular inspections and compliance with CSA standards
Failing to meet these requirements can result in shutdowns or legal action by the Ministry of Labour.
4. Soil Conditions That Demand Shoring
Some soil types are inherently unstable and require immediate support:
- Wet or saturated soils (clay or silt) increase collapse risk
- Loose sand or granular soil lacks cohesion
- Fill or backfilled areas can shift unpredictably
Contractors must perform a soil classification before beginning any trench work.
5. The Hidden Costs of Avoiding Shoring
- • Medical expenses or lawsuits from injuries
- • Equipment loss in cave-ins
- • Repairing adjacent property damage
- • Higher insurance premiums
- • Reputation damage
6. Best Practices for Shoring
To avoid disaster and stay compliant:
- Always assess soil type before excavation
- Use trench boxes or shields in unstable areas
- Train staff on proper shoring procedures
- Perform daily inspections of shoring systems
- Keep records of all safety measures and engineer sign-offs
7. Shoring in Urban Construction
In cities like Toronto, where construction often occurs beside active buildings and tight spaces:
- Vibration and load pressure can compromise neighboring foundations
- Shoring protects not just the trench, but the entire worksite environment
- Some municipalities require pre-construction shoring plans and geotechnical reports
Urban builds make skipping shoring even more dangerous and unacceptable.
Final Thoughts
- Shoring is not optional—it’s essential. Whether you’re working on a small residential trench or a large urban development, proper shoring protects lives, budgets, and reputations. Cutting corners may save a few hours today, but it can cost far more tomorrow.
