Top 4 signs your sewer line is
We can save your sewer
Drain Backups
A failing sewer line will not drain the water properly. This flow-restriction causes major damage over time.
Unpleasant Odors
Wastewater in a failing sewer line releases sewer gas that travels into the building. You can smell this near the drains.
Standing Water
A particular area of the ground turns wet, muddy, or develops puddles of foul wastewater. You observe foul odors.
Sinkholes
Leaking wastewater from a failing sewer line over saturates the soil, damaging the property's foundation.

Stages of Advanced Pipe Rehabilitation†
don't dig the line
Inspection & Assessment
We begin with a high-resolution camera inspection to identify pipe damage, blockages, and overall condition.
Pipe Cleaning & Prep.
The existing pipeline is thoroughly cleaned using hydro-jetting or mechanical methods to ensure a smooth surface for lining.
Liner Installation
A resin-saturated liner is inserted into the damaged pipe and cured in place using steam, hot water, or UV light, creating a seamless new pipe inside the old one.
Final Inspection
After curing, we conduct a final camera inspection to ensure a perfect seal and restore full functionality.

Common Pipe Materials We Service
Clay Pipes
Found in older sewer systems, clay pipes are durable but prone to cracking and root intrusion over time.
Cast Iron Pipes
Common in commercial and residential buildings, cast iron corrodes internally, leading to restricted flow and leaks.
PVC Pipes
Lightweight and corrosion-resistant, PVC is widely used but can crack or shift due to soil movement.
Orangeburg Pipes
A fiber-based material used in mid-20th-century sewer lines, Orangeburg deteriorates and collapses with age.

The Infrastructure Crisis
Why Commercial Systems Fail
Commercial sewer mainlines face unique challenges compared to residential systems. Higher flow volumes, aggressive chemical waste, and extended operating hours accelerate deterioration.
Key Statistics:
- 240,000+ water main breaks occur annually in the US
- EPA estimates $271 billion needed for wastewater infrastructure over 20 years
- Average sewer pipe age in commercial districts: 45-60 years
Common Failure Modes
Understanding Deterioration
Hydrogen Sulfide Corrosion
Bacterial conversion creates sulfuric acid, dissolving concrete crown
Root Intrusion
Tree roots penetrate joints seeking moisture, causing blockages and breaks
Offset Joints
Ground settlement creates misalignment, reducing flow capacity
Grease Accumulation
FOG (fats, oils, grease) builds up, reducing pipe diameter by 30-80%
Scale Buildup
Mineral deposits and biological growth restrict flow
Pipe Collapse
Complete structural failure from age, corrosion, or external load
