Excavation is often the first step in any construction project. Once teams have cleared ample space, building crews will use a shoring technique to support the future floors and walls to help property owners avoid foundation repair in the future. There are different types of shoring used for various jobs, as the guide below explains.

What Are Popular Methods of Shoring?

1. H or I Beam

H or I-beam shoring is the most common technique, often used in shallow excavations and projects requiring standard basements. It involves driving steel beams directly into the ground, in either an I or H shape. Then crews can install a concrete panel between the two steel beams on either side to construct walls and hold both sides up. 

2. Diaphragm Walls

Diaphragm walls are solid walls made of reinforced concrete. Teams may install these temporarily or make them part of the permanent retaining wall structures. This option is utilized for deep excavations, like those for extensive basements or tunnels. 

3. Secant Pile

Secant pile shoring involves combining two piles to form a continuous wall, though one typically receives extra support. A guide beam ensures these piles are correctly aligned. In addition to being used for deep excavations, this is also a preferred method when there is limited space available surrounding the site. 

4. Contiguous Pile

Contiguous pile shoring involves adding multiple piles in a row, arranged so that they are almost touching. These piles can effectively retain dry aggregate or filler material, which is often used for drainage. However, this option is best suited for dry areas since water seepage may be a concern, leading to the need for foundation repair.

5. Sheet Pile

Sheet pile shoring involves driving Z or U sections of steel directly into the ground around a site's perimeter. These are then connected and can even be welded together to reach the desired depth. This method is often chosen for excavation sites near bodies of water to prevent moisture from getting through.
