Trench Shoring Services
Critical safety systems preventing soil collapse during excavation work with hydraulically-operated slide rail protection
Understanding Trench Shoring
What is Trench Shoring?
Trench shoring is a critical safety system designed to prevent soil collapse during excavation work. Our service provides temporary structural support for trench walls using hydraulically-operated slide rail systems that are installed progressively as excavation proceeds.
The system consists of vertical steel rails, horizontal shoring plates, and adjustable bracing extensions that create a protective barrier between workers and potentially unstable soil walls. We deploy parallel slide rail systems utilizing the "dig and push" methodology, where shoring components are progressively installed as excavation deepens, minimizing worker exposure.
Traditional Excavation Risks
Unprotected excavations create severe safety hazards:
- ✕Soil collapse risk - worker entrapment
- ✕Adjacent structure damage
- ✕Utility line exposure and damage
- ✕Extended project timelines due to safety concerns
- ✕High liability and insurance costs
Shoring System Advantages
Professional shoring provides comprehensive protection:
- Continuous worker protection during excavation
- GS-Certified safety standards compliance
- Progressive installation methodology
- Rapid installation vs. traditional methods
- Reduced insurance and liability exposure
