King Post Walls: Your Reliable Ally for Soil Retention


When it comes to construction and civil engineering projects, maintaining soil retention is a top priority. Thankfully, there’s an effective solution at hand: king post walls! In this article, we’ll explore the wonderful world of king post walls and how they can help keep your soil stable and secure.

Understanding King Post Walls

Let’s get acquainted with our hero, the king post walls! Also known as soldier pile walls or soldier beam walls, they’re like sturdy soldiers protecting your soil. These walls consist of vertical posts made of steel or concrete, called soldier piles, that are firmly rooted into the ground at regular intervals. To make them even stronger, horizontal members called lagging or planks connect these soldier piles. Together, they form an unyielding barrier against soil movement, giving you peace of mind.

Soil Retention Benefits

The beauty of king post walls lies in their ability to retain soil effectively. They come to the rescue in a range of construction scenarios, stabilizing embankments, excavations, and other structures. By preventing soil from shifting or collapsing, these walls maintain the stability of your project. They’re particularly useful in loose or waterlogged soil prone to erosion. From building basements to underground parking lots and bridge abutments, king post walls have your back when it comes to soil retention.

Design and Construction

Creating king post walls requires careful planning and construction. The size and spacing of the soldier piles, along with the thickness of the lagging, are all determined based on soil properties, expected loads, and the desired performance of the wall. The installation process may vary, but typically, the soldier piles are either drilled or driven into the ground, and the lagging is then inserted between them. For added stability and strength, ground anchors or tiebacks can be incorporated into the design.
