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.

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.

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.

All building foundations will settle with time, but problems arise when this settlement is uneven or extreme. Sometimes requiring pier drilling or helicals.
Are you wondering if you have foundation issues with any property that you own? All building foundations will settle with time, but problems arise when this settlement is uneven or extreme. Continue reading “Pier Drilling Can Shore up a Sagging Foundation”
Before excavation and construction can begin at a construction site, ground improvements must be done to manage groundwater and improve soil strength. Otherwise the site may not be able to provide adequate support for the planned foundation. There are several methods which can be used to accomplish this, depending on the conditions of the soil. To determine the need to make soil improvements prior to the work of the excavating contractor, it may be necessary to consult with a civil engineer.
The long-term structural stability of any building depends on having a well-built foundation in place. In a region subject to earthquakes, it is especially important for a highly reputable Bay Area excavating company to set the stage for that strong foundation. It is easy to build something passable, but it takes a well managed, well supervised and well executed excavation to build a foundation that will stand the test of time.

Pier drilling is a process which uses an augur to drill deep down into the ground, for the purpose of establishing piers or columns upon which a foundation can be placed to support a structure above ground. It is very often used in locations where the ground is not particularly stable, and where it would be unsafe over the long haul for building construction. Piers are often drilled down deep enough so they can rest in either stable ground, or on solid bedrock, which can provide a very solid base for supporting anything above.

Avoiding problems with your home’s foundation is critical to the long-term stability of your home, which will also save you money on costly repairs. In the San Francisco Bay Area, such problems can be prevented by installing deck piers, footing piers, helical piers, concrete piles, or other constructs which can provide foundation support to keep your home’s base completely stable. As a homeowner, here are some things to look for in in order to prevent foundation problems. Continue reading “Four Ways to Prevent Home Foundation Problems”
