When you choose a builder, landscaper or pool company, you also are choosing numerous other sub-contractors that will work in conjunction with the primary contractor you have chosen. This is especially true when heavy excavation or drilling is part of the project. Few contractors do this type of work themselves (in-house) because the equipment investment is very high, and the training needed get it done efficiently and safely make it prohibitive for contractor to do it themselves.
Many public utilities have underground piping which is used to deliver services to all the residents and businesses of a given community. To avoid any injuries, damage to utilities, and or interruption of service, it is necessary to locate where these Utilities before beginning any excavation work. There are some hefty fines which can be levied against individuals or companies who damage utility lines.
How to Locate and Identify Underground Utilities
Pier drilling and pile driving are techniques used for driving pier or piles into the ground underneath a structure to shore up sinking or sagging building foundations, bringing them back to their proper level and preventing further foundation settlement.
Also called “piering,” this method involves the use of strategically placed mechanical jacks to slowly and carefully lift the settled foundation beam to grade. Once raised, the beam is held to elevation by attaching it firmly to the piers.
There are two common types of foundation piers: Continue reading “Using Piers and Piles to Shore Up Sagging Foundations”
Helical Pier drilling in the Northern California can be thought of as a system which uses anchors to secure structures to the ground when soil conditions are rather challenging, and where the usage of a more conventional foundation system is not indicated. These piers consist of a steel shaft with helicals that make it look like a very large screw, and help to secure any structure tied to it. It is especially useful for drilling where there is unfavorable ground conditions. Continue reading “When to Use Helical Pier Drilling”
The Northern California rainy season has begun, and with it come special challenges for construction project crews.
The most common wet weather dangers are “slips, trips and falls.” These dangers are particularly prevalent when working in elevated positions such as when using scaffolding, hand holds, stairs and ladders. Even after the rain stops, conditions remain muddy underfoot for days.
Strong winds create their own hazardous conditions, scattering unsecured materials and putting pressure on scaffolding. Wet and windy weather can also make driving and operating excavation machinery more dangerous due to slick conditions and reduced visibility. Continue reading “Excavating and Drilling in Wet Weather”
Excavation and trenching are naturally hazardous construction operations, and contractors need to take all the appropriate steps to ensure worker safety. The Occupational Safety and Health Administration (OSHA) defines an excavation as “any man-made cut, cavity, trench, or depression in the earth’s surface formed by earth removal.” A trench, in particular, is defined as “a narrow underground excavation that is deeper than it is wide, and is no wider than 15 feet (4.5 meters).”
When we approach any excavation, drilling or demolition job we keep safety first, starting with the planning for the job. It is not just the possibility of the sides of an excavated plot or trench collapsing. Safety planning also must accommodate the interaction of our people and the machines they need to employ to carry out the job, and the terrain on which those machines must operate.

Foundations vary in structure relative to the depth to which the foundation must be established in the ground. Small structures might only require a shallow foundation, which involves excavating between three and eight feet into the ground, before pouring a concrete footing.
Commercial Building Foundations
Homeowners don’t often think about the foundations of their home, but those foundations are critical components of any home, as they bear the entire load of the structure above. Foundations also have another critical function, in that they must prevent groundwater and soil vapors from penetrating into the home’s interior. When you’re trying to decide what kind of foundation your new home should have, there are four choices available to you, and each has advantages and disadvantages.
Choosing a Home Foundation
One of the typical methods for anchoring ground-mounted solar arrays has been to use a slab of concrete for the foundation. Helical piles are gaining popularity among designers and contractors, though, to provide solar array owners with a more stable installation. Helical piles provide some distinct advantages, so it is worth considering the use of helical piles as anchors for these solar arrays.
Benefits of Helical Piles
What seems like a straightforward business, drilling and excavating, actually has a lot of parts to it that all have to work together. Here are some of the key aspects of running a business like ours.
