Retaining & soil nailing
Soil nails, anchors, shotcrete, or retaining walls stabilize excavations and slopes around foundations.
Urban basements and hillside sites require knowledge of strata, groundwater, and neighboring foundations before selecting nail length or support type.
Options include secant or soldier piles, sheet piles, slurry walls, soil nails, and rock anchors.
If architectural documents show only a basement wall and omit excavation support, risk is displaced onto construction. Collaboration is essential.
Permanent systems must align waterproofing, drainage, and corrosion allowances with the structure’s design life.
