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”
With our winter season arriving, as a homeowner you should take some steps to winterize your foundation against the colder, wetter weather. This is not something you should overlook, as the foundation of your home is literally the base for the entire structure which rests upon it, supporting everything inside your home. Here are some tips that will help prepare your home’s foundation for winter. Continue reading “How to Winterize Your Home Foundation”
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.

Helical anchors enjoy widespread use today to help stabilize and secure above-ground structures, especially when that structure is built on ground that may be or has become unstable. The anchors themselves are steel shafts with helical coils or plates welded on at an angle. The shafts are screwed into the soil beneath the foundation to a depth that enables the coil to support the load. When foundation drilling calls for helical anchors, the depth of the anchor is drilled into the ground is determined by precisely measuring the torque it takes to turn the anchor. Generally, the higher the torque value the more stable the soil. This gives soil and structural engineers an accurate indication of the load-bearing capacity of the helical anchors.
