Construction contractors and developers rely on excavation contractors to complete various tasks including trenching services.
Soil beneath and around new structures plays a large role in the success of a new building or home.
Let’s dig deeper into some specialty trenching services to further explain their importance for you!
Underground Utility Conduits
You already know that residential and commercial buildings require basic utilities such as plumbing, electricity, cable, phone lines and even fiber optics.
Calling on an excavation service is preferred to dig trenches that will house a protected underground passage for electrical channels or waterways (sewer or drainage).
It may be tempting to perform these steps on your own, but hiring the professionals can save you time, take a load off your shoulders and add to the safety of your site.
How do you dig a trench for conduit?
When digging trenches for conduit, there are a lot of things to consider before the project begins.
First of all, your professional excavation contractor will consult the NEC (National Electric Code) to get the correct depths for the specific trench that is needed.
Then, we will create a visual guide so that the location for digging is clear. Once the trench is completed, the other necessary trades may begin working to install the utilities before the trench is backfilled.
Planning to prevent damage from improper site drainage should be completed in every construction project.
Excavators are key to ensuring water drains away from structures to prevent erosion and potential flooding. Drainage trenches can be engineered to hold drainage pipes that carry water from gutters and runoff away from structures.
Electrical trenching is another specialized form of trenching that is critical in new construction sites.
For commercial buildings, homes or housing developments, electrical trenching provides a way for power to be distributed without the need for dangerous overhead powerlines.
Your excavation company works closely with engineers from the utility company to plan where the transformer box will be placed.
Digging then begins on the electrical trenches running from the transformer to each required destination.
Another specialty trenching service that must be completed is waterline trenches. It’s important to note that water lines must generally be buried 12 inches below the frost line in most states.
While this may not seem as important in areas that do not often experience freezing temperatures, every state has laws that guide contractors to prevent frozen pipes and costly repairs.
Waterline trenching is necessary to allow water to be run underground from wells, city water lines, or to connect buildings.
Your excavator will plan the best route to provide an unobstructed flow.
Sewer Line Trenching
Similar to the waterline, trenches are needed to be built for efficient sewage removal. Easy access to sewer lines for maintenance must be considered as well.
As with each utility that must be buried, the codes for sewer line trenching include provisions for health and environmental protection.
Gas & HVAC Piping Trench Service
Natural and Propane Gas are both used for heating buildings and homes throughout the country. Providing specialized trenches for these utilities can protect them from damaging environmental factors.
Many areas also use Geothermal Heat Pumps which require specialized trenches to house and protect the pump and piping underground.
When installed and buried correctly these systems can last 25-50 years without needing to be replaced.
Foundations provide support to structures ranging from sheds and garages to multi-story houses and commercial buildings.
Trenches must be dug in specific locations and then filled with concrete and metal to provide support for the building.
The depth of these trenches will be based on the size of what is being built.
As with other specialty trenches, this will be meticulously planned out by an engineer or architect and included in the building plans.
Trenching for Retaining Walls
Digging trenches for retaining walls provides needed support to hold back soil that would otherwise erode or create a landslide.
Much like trenches for foundations, a trench dug for a retaining wall gives stability to a wall that will be under a lot of pressure from earth and water absorbed through precipitation.
Without a specially dug trench, the retaining wall is liable to collapse under the immense weight. This is often on properties with uneven ground or hills.
