San Luis Obispo Trenchless Technology is an advanced technique for replacing, repairing, or installing underground infrastructures such as sewer pipes and utility lines. Using a combination of advanced methods, materials, and equipment, Coastal Construction & Engineering can complete underground projects with minimal disruption to surface activities and traffic.
Minimal disruption means:
Along with significantly minimizing disruptions, trenchless technology:
Applications for trenchless technology include installing, repairing and retrofitting sewer lines, water lines, and underground utility lines.
Coastal Construction & Engineering is uniquely qualified for underground installations, repairs and connections because the company holds the California “A” General Engineering Contractor license. Among other specialized tasks that are associated with sewer and water lines, the “A” license is the only one that grants the license holder the ability to connect sewer lines to a public street.
Too many times, property owners rely on a well-meaning plumber without the proper licensing to thoroughly repair pipes and properly reconnect the new pipe to the public utility on the street. Without the correct connections, leaks continue, resulting in additional costs and more problems.
Rely on Coastal Construction & Engineering for top-quality underground installation, repairs, and retrofitting. How does trenchless technology work?
Trenchless technology does not disrupt the ground above. No more time-consuming, labor-intensive digging and trenching. Only two surface holes are drilled for special drill heads to enter and exit the ground. No trenches. No ditches. No huge piles of dirt that need to be backfilled (or hauled away if contaminated by sewage), turn to mud in the rain or blow dust around in the wind.
Two examples of trenchless technology are Pipe Bursting (replacing underground lines) and Horizontal Boring (installing new underground lines). Coastal Construction & Engineering does both.
Pipe Bursting
Pipe bursting is used to replace damaged pipes for sewer, water, gas, or electrical conduit. It also is optimal for increasing pipe size.
High-density polyethylene (HDPE) pipe is attached to a special head that bursts the old pipe as sophisticated equipment directs the head forward. As the head travels, it pulls the new pipe behind.
Upon arriving at the destination, the head exits through a hole and Coastal Construction & Engineering makes the final connections.
Horizontal boring
Sometimes called “directional boring” this method is accomplished by pushing a specialized drilling bit through the soil at a specific angle until a specific depth is reached. Once that depth is reached, the drill tip levels out and continues boring horizontally.
When the drill head reaches its destination and breaks through the soil surface, it is replaced with a “back reamer” to which the new pipe or conduit is connected. The back reamer is pulled back through the newly bored “trench,” laying out the new pipe on its way.
Horizontal boring is most commonly used for new pipe or conduit installations.
