Earth Retention System Design Services

These retaining walls are used in deep excavations and happen in stages. The application is adequate for soil with cohesion and a lower water table.

This type of ground retaining structure is used for deep and narrower excavations. These walls or walers are installed laterally to support the soil, and struts run across the supports. Braced walls are fitting for ground with cohesion and a lower water table level.

Soldier pile walls work for soil with a higher water table, but less for cohesionless soil. The soldier beams are placed in the ground with lagging timber at the front flange to retain the soil during excavation.

Diaphragm walls are a traditional method used in big construction projects operating under the water table. In regions where the water table reaches the surface, water can press against the foundation’s bottom. Without adequate support, the force of hydrostatic pressure can cause water to seep through the foundation and even permeate solid concrete in the long term.

Diaphragm walls are created and inserted in a slurry trench. The slurry trench helps avert soil from entering the channel. The slurry is replaced with a concrete wall, which can be temporary or permanent.

Prefabricated diaphragm walls follow a similar principle, but panels are set inside the trench and slurry mixture.

These supports are used mainly in water-bearing soil. Sheet pile walls are seldom used in urban areas for several reasons. The frequency of buried pipes and public utilities poses a challenge, as do hard layers and boulders.

Pile walls are used for deep excavations. Common types include secant bored, intermittent bored and tangent bored piles.

Secant bored pile walls are watertight walls that may be more economical than other options. Depending on the amount of cement used, their construction can be soft-hard or hard-hard. Intermittent bored walls are mostly suited for cohesive ground and do not demand water tables.

Tangent bored piles are the go-to choice when diaphragm walling and secant piling equipment are unavailable, like in situations where groundwater exists. Groundwater can create significant problems if not tended to by professionals, so quality work is vital.
