Residential and Commercial Site Excavation Long Island, NY

Conventional digging and trenching

Allied / All-City provides full-service conventional excavation for residential and commercial properties including foundation digs, utility trenches, parking lot removals, and grading. Our crews perform careful pre-construction surveys, coordinate underground utility locates, and implement erosion and sediment controls to protect surrounding property. We handle traffic control, temporary shoring, and dewatering when needed to meet safety and code requirements. After excavation we use compaction testing and grading to prepare a stable base for contractors, asphalt, concrete, or landscaping. For urgent jobs we deploy rapid-response teams to limit operational disruption and quickly restore site function.

Shoring, Dewatering & Cleanup Long Island, NY

Safety systems and site restoration included.

Deep or wet excavations require shoring, bracing, and dewatering to protect workers and neighboring structures. We design and install temporary shoring systems and pump systems to lower groundwater for safe excavation. After work is complete we perform proper backfill, compaction, and surface restoration — from asphalt and concrete repairs to landscaping and curb reinstatement. Our crews follow OSHA and local regulations, maintain daily logs, and coordinate inspections to ensure a safe, code-compliant outcome that leaves your site clean and ready for the next phase.
