Retaining Walls

Retaining walls are constructed for various purposes including soil containment (to prevent the soil's down-slope movement and soil erosion), creation of flat, usable areas and living spaces and construction of basements.

Sinai Construction Engineering has over three decades' experience in structural and concrete work and extensive expertise in retaining wall construction. With us, you can be assured of getting a strong and solid retaining wall that performs its intended purpose.

We also provide expediting services that will relieve you of the hassle of obtaining permits and coordinating with various engineering professionals in case your retaining wall build is subject to more rigorous building requirements — as is the case if your retaining wall is greater than 4 feet in height. For such builds, an engineered plan is required as well as retaining wall permits and varying grading requirements such as a Geologic and Soils Engineering Exploration Report.

What to Expect in Retaining Wall Construction

Depending on the purpose of the retaining wall construction and the particular needs of the job site, Sinai Construction Engineering will build a Concrete Block Retaining Wall or a Poured-in-Place Retaining Wall.

Poured-in-Place Retaining Wall

This type of retaining wall is built according to the dimensions specified in the construction plan. It is properly reinforced with steel and filled with concrete. Poured-in-place retaining walls could be poured plain / smooth-faced or with a variety of designs such as brick for aesthetic purposes.

Concrete Block Retaining Wall

A concrete block retaining wall is constructed by using hollow core CMUs (Concrete Masonry Units) reinforced with steel and then filled with concrete.

"I want to thank everyone at Sinai for the great job you did at our house. I actually know a fair amount about construction and it was very gratifying to see your crews always making sure things were just perfect. They never failed to arrive early and stay late when necessary. They did not complain when some unexpected snag developed (in our case multiple old tree roots), and just going non-stop to get the project done right and on schedule. In all, Sinai's office staff and work crews provide professional, quality work at what I believe are reasonable prices. I'm not trying to write an advertisement for Sinai but just wanted you to know that my wife and I are very pleased and very happy with your crews and their work."
