Excavation and Trenching Services in Napa, Sonoma and Marin County

When choosing a plumbing company to perform sewer & drain replacement, a property owners main focus should be the excavation portion of the job. Trenches and tunnels must be excavated to expose the sewer & drain lines for repair. Tunneling beneath a commercial or residential building requires specific procedures and safety standards. It is a complicated process that only a true professional can perform. When we tunnel beneath your foundation, we make sure you are educated and informed every step of the way. We invest in the best training methods and equipment ensuring that tunneling is achieved safely, promptly and effectively. Our employees hold multiple OSHA certifications and attend safety training workshops regularly.

When choosing a excavating company, it is important that you ask questions, such as:

  • Are the excavators employees or sub-contractors?
  • Do the excavators follow required OSHA procedures?
  • Do the excavators have OSHA certifications?
  • Are the excavators insured?
  • Will I receive an engineer’s letter from the excavators?
  • Do the excavators have a contractors’ license or contractor registration card?

At Group Infinity Construction we strive to work in a safe, clean and efficient manner at all times. The construction of underground tunnels are an essential but dangerous activity. Working under reduced light conditions, difficult or limited access / egress, with the potential for exposure to air contaminants, underground workers face many dangers. To help employers protect the safety and health of underground construction workers, the Occupational Safety and Health Administration (OSHA) has prepared a number of guidance documents, including the underground construction regulations, found in Part 1926, section 800 of Title 29 of the Code of Federal Regulations (29 CFR 1926.800). We take these guidelines seriously and follow them closely.
