Retainig Walls & Terraces
What is a retaining wall?
A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. Its basic function is to hold back earth or water. Such walls must be designed and installed by professional engineers who understand the tension that will be placed on the wall, the strength needed to tolerate that strain reliably, and the type of materials best suited to performing the job appropriately. Retaining walls are very common in areas where there may not plenty of open land, specifically for gardening and landscaping purposes. Such wall can help you create different levels in the side of the graded land, using the available space as completely as possible.
Do you live in a hillside area that is prone to landslides? Is your house ready for the El Nino? Do you need to hold back soil surrounding an excavation?
The cost of a retaining wall in California is not expensive if you plan It right and do it correctly, the difficulties start when you need to redo it all over, it can be very pricey. Failure of the wall will most certainly cost you a bundle, and this is the best scenario. Damages to property or lives are also a probability. A well-thought-out retaining wall can not only save lives, but will allow you to take advantage of your lot. At Infinity Construction we can build a retaining wall to support vertical grade changes, prevent downward slope movement or create beautiful terraces.
Constructing a retaining wall involves a great amount of engineering and planning, Geologic and Soils Engineering and Exploration Reports to accommodate every possible scenario and to prevent a disaster in an attractive way. We have great experience with building rigorous retaining walls and permitting them by the city code. Whether the aim is hillside stabilization, generating more yard space or preventing landslides we will design, engineer and build the most practical retaining wall.
If you have any questions about a new retaining wall, or adjusting an existing one, give us a call and we will send an expert to inspect the site for free and advise you on what should be your next step based on the site conditions and your own personal objectives.
Different Types of Retaining Walls:
Gravity retaining walls:
Gravity walls rely on the weight of their mass (stone, concrete or other heavy material) to resist the pressure from behind and usually will have a setback to improve stability by leaning back into the retained soil.
Cantilevered retaining walls:
Cantilevered retaining walls are prepared from an internal stem of steel-reinforced, cast-in-place concrete or mortared stone. These walls cantilever loads (like a beam) to a big structural footing, converting horizontal pressures from behind the wall to vertical pressures on the ground below. Sometimes cantilevered walls are buttressed on the front, or include a counterfort on the back, to improve their strength resisting high loads. Cantilevered retaining walls uses significantly less material than a gravity wall.
Sheet piling retaining walls:
Sheet pile retaining walls are commonly used in soft soils and fitted spaces. Sheet pile walls are made out of wood, vinyl or steel planks which go deep into the ground. (about 2/3 below ground, depending on the surroundings). Higher sheet pile walls must be assisted by a tie-back anchor placed in the soil a distance behind the face of the wall, and is tied to the wall, usually by a rod or a cable.
Anchored Earth walls
Any wall which uses facing units tied to rods or strips which have their ends anchored into the ground is an anchored earth wall. The anchors are like abutments. The cables used for tieing are commonly high strength, prestressed steel tendons. To aid anchorage, the ends of the strips are formed into a shape designed to bind the strip at the point into the soil.
