Retaining walls have proven useful in a variety of ways, primarily to prevent soil from sliding off steep slopes. Many property owners use them when installing patios, decks and basements. However, you want to make sure your retaining wall installation will last.
That's where Omega Structural, Inc. comes in. When you hire us for your retaining wall installation, you'll work directly with our structural engineer to make sure everything will work as it should. We offer services throughout Los Angeles, CA and the surrounding area.

Retaining walls have a wide variety of uses around the yard, all of which involve keeping earth from spilling off a steep slope. They're indispensable in the creation of sunken patios, walkout basements, and any other landscape with an abrupt separation of ground elevation.
The purpose of all retaining walls is to hold soil behind them. However, the specific needs will vary depending on the project. Walls can range from small landscape stone walls to surround a garden to enormous soil-retaining projects along a highway.
Others can help control erosion from hard rains or create a terraced yard to reduce maintenance. When you begin the initial planning, there are several considerations that will affect the material and type of wall you build. Location, Soil, Design & Drainage
Retaining Walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope). They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses.
A basement wall is thus one kind of retaining wall. But the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side. The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures.
Every retaining wall supports a "wedge" of soil. The wedge is defined as the soil which extends beyond the failure plane of the soil type present at the wall site, and can be calculated once the soil friction angle is known. As the setback of the wall increases, the size of the sliding wedge is reduced. This reduction lowers the pressure on the retaining wall.
The most important consideration in proper design and installation of retaining walls is to recognize and counteract the tendency of the retained material to move down-slope due to gravity. This creates lateral earth pressure behind the wall which depends on the angle of internal friction and the cohesive strength of the retained material, as well as the direction and magnitude of movement the retaining structure undergoes.
Lateral earth pressures are zero at the top of the wall and - in homogenous ground - increase proportionally to a maximum value at the lowest depth. Earth pressures will push the wall forward or overturn it if not properly addressed. Also, any groundwater behind the wall that is not dissipated by a drainage system causes hydrostatic pressure on the wall. The total pressure or thrust may be assumed to act at one-third from the lowest depth for lengthwise stretches of uniform height.
It is important to have proper drainage behind the wall in order to limit the pressure to the wall's design value. Drainage materials will reduce or eliminate the hydrostatic pressure and improve the stability of the material behind the wall. Drystone retaining walls are normally self-draining.
Set a date for an Inspection with one of our specialist. One of our qualified inspectors will visit your property for a proper and detailed inspection.
We will send you our detailed proposal. You can review our proposal and of course we are open for any questions or concerns that you might have. We will be more than happy to answer all of your inquiries.
We will take care of your project. Omega handles all built drafting, designs, and engineering calculations of your project.
All your property plans while be prepared by our team. We will also get the PERMITS and APPROVALS for your city. LA County and surrounding areas.
Job Walkthrough. The project manager will conduct the Job Walkthrough with the property owner or property manager to notify and show about the work to be executed and what to expect.
Notification to tenants. We will notify your tenants if applicable with the job schedule to proceed with the construction.
A temporary foundation is constructed to bear the weight of the building.
A needle beam is a new beam that is constructed at right angles to the existing foundation. Once the beam has been pushed in, the gap between it and the foundation wall is sealed with strong cement mortar.
Once the temporary foundation is in place and has been checked, a pit can then be dug by hand below and around the existing building. The foundation is then underpinned by filling the pit with concrete.
Site-poured concrete. It means that the concrete material is poured, molded and cured onsite.
Once the concrete has set, the temporary foundation can be removed. The concrete is the new, enlarged foundation giving it a higher safe bearing capacity.
Stucco and Paint. Good News! We will apply a building material used for the protective coating of walls and ceilings then paint to make sure your property is safe and beautiful.
Now, Your property is REPAIRED, SECURED, and DURABLE for SAFETY REGULATIONS and from any SEISMIC ACTIVITIES and SETTLEMENTS!
