Controlled Trenching & Site Preparation

Precision trenching and site preparation for underground utility installations. Work includes proper excavation, grading, alignment, bedding preparation, and trench restoration to support sewer, water, storm, and fire line systems.

Trenching & Excavation Safety

Dryos Excavating LLC  performs trenching operations in compliance with OSHA safety standards. Typical trench depths range from approximately 5 to 10 feet. When deeper excavation is required, proper protective systems such as trench boxes, engineered shoring, or sloping and benching are used based on site and soil conditions. No employee is permitted to enter an unprotected trench. Safety, controlled excavation, and jobsite risk management are part of every project we perform.
