Earth Retention Services

This versatile earth retention system utilizes vertical steel piles and horizontal lagging to provide robust temporary or permanent support. It is an ideal, cost-effective solution for deep excavations where ground conditions allow for arching between piles.

Tieback anchors provide essential lateral stability by anchoring retaining walls deep into stable soil or rock. These high-capacity systems maximize open workspace within an excavation by eliminating the need for bulky internal supports.

This “top-down” construction method reinforces the existing soil mass with closely spaced steel tendons and a shotcrete facing. It is a flexible, efficient choice for stabilizing slopes or creating excavations in constrained urban environments.

Formed by intersecting reinforced concrete piles, secant walls create a continuous, stiff barrier that is virtually watertight. This method is the gold standard for deep foundations in high-groundwater areas or sensitive sites where minimizing soil movement is critical.

When site constraints prevent the use of tiebacks, internal bracing systems, using struts, rakers, or corner braces, provide the necessary structural rigidity. DBM will engineer these layouts to ensure maximum safety while maintaining as much operational clearance as possible.

Underpinning stabilizes and strengthens the foundations of existing structures to prevent settlement during adjacent construction. Whether by utilizing micropiles or soldier piles, underpinning will ensure the integrity of neighboring buildings is protected throughout the project lifecycle.
