Trenchless Sewer Repair & Replacement

Fast, minimal-disruption trenchless sewer and water line services for commercial properties across Nassau & Suffolk County.

Allied / All-City specializes in trenchless sewer repair and replacement for commercial properties across Long Island. We serve schools, multi-unit buildings, restaurants, retail, and municipal sites with pipe-bursting, pipe-lining, directional drilling, and hydro excavation. Our no-dig methods preserve landscaping, parking lots, and operations — reducing restoration costs and downtime. Using industry-grade equipment and certified crews, we diagnose issues with CCTV inspection, recommend the right trenchless fix, and complete work to code with permits and inspections handled. For urgent issues we deploy rapid-response teams 24/7 to minimize loss of service and liability.

Pipe Bursting Services

Efficient pipe replacement without full excavation.

Pipe bursting is ideal for failing cast iron, clay, or corroded pipes under pavement or landscaping. Our crews insert a bursting head to fracture the old pipe while pulling a new, high-density polyethylene (HDPE) pipe into place — all with minimal surface disruption. For commercial sites this means replacing service or main lines under driveways, sidewalks, or parking areas without costly closures. We pair bursting with CCTV pre- and post-inspections, pressure testing, and proper tie-ins to ensure flow, compliant connections, and reliable long-term performance.

Sewer Line Benefits

Why choose our trenchless solutions

Faster repairs, lower restoration costs, and reduced operational disruption for commercial properties.

Minimized Downtime — Get businesses back online faster than full-excavation methods.
Lower Restoration Costs — No large trenches means less paving, landscaping, or concrete repair.
Safer Work Zones — Reduced open-excavation hazards for customers, staff, and tenants.
Long-Lasting Results — Modern lining and bursting materials extend lifespan of replaced lines.
Accurate Diagnostics — CCTV inspections locate failures precisely to target repairs.
Code-Compliant Permits — We coordinate permits and inspections with Nassau and Suffolk authorities.

Directional Drilling & Hydro Excavation

Precision installations and safe excavation alternatives.

Horizontal directional drilling (HDD) allows new sewer mains to be installed under roads and obstructions with a small access pit. For exposed tie-ins or locating utilities we use vacuum/hydro excavation to safely expose lines without damaging existing infrastructure. Combined, these trenchless, hydro, and vacuum techniques protect site operations and reduce liability. We also offer emergency bypass pumping, industrial piping, septic/cesspool work, and regular pipeline cleaning to keep commercial systems operating smoothly. Every project includes a clear scope, timeline, and after-care recommendations to protect your facility’s schedule.

Common questions about Commercial Sewer Services

What is trenchless sewer repair and is it right for my business?

Trenchless repair replaces or lines pipes with minimal digging using pipe-bursting or cured-in-place lining — it’s ideal when you need to protect pavement, landscaping, or minimize downtime.

How long does a commercial trenchless sewer job take?

Most simple repairs and replacements are completed in a day or two; larger main replacements vary but are significantly faster than full excavation methods.

Will you handle permits and inspections?

Yes — we coordinate permits, inspections, and utility notifications with Nassau or Suffolk County to ensure code-compliant work.

Do trenchless fixes last as long as new pipes?

Modern materials like HDPE and cured-in-place liners provide durable, long-lasting solutions often matching or exceeding the lifespan of traditional piping.

Can you work around business hours to avoid disruption?

Absolutely — we schedule around operations, offer after-hours crews, and provide rapid emergency response to reduce impact.

How do you locate the blockage or failure?

We use closed-circuit TV (CCTV) pipe inspection and sonar/locating tools to pinpoint issues, then recommend the least disruptive repair option.
