Seylone provides vacuum excavation services — also known as soft-dig, hydro excavation, orpotholing — for non-destructive utility exposure in congested urban environments across the NYCmetro area. Vacuum excavation uses either pressurized water (hydro-vac) or compressed air (airvac) combined with high-powered vacuum to safely expose buried utilities without the mechanicalimpact of conventional excavation.

‍

Soft-dig is the preferred method when underground utilities are closely spaced, when utilityowners require non-mechanical exposure, or when the project specification mandates nondestructive excavation techniques. It is especially critical near high-risk infrastructure includinggas transmission mains, high-voltage electric feeders, fiber optic trunk lines, and steam systems— where even minor contact during conventional excavation can result in service disruption,safety incidents, or regulatory penalties.

‍

Seylone operates vacuum excavation trucks equipped for both hydro-vac and air-vac methods,allowing our crews to select the appropriate technique based on soil type, utility sensitivity, andsite conditions. Air-vac is used around electrical infrastructure and fiber optics where watercontact is prohibited. Hydro-vac is used in compacted soils, fill material, and clay where air alonecannot effectively loosen the material.
