What our leach field service includes
Soil absorption testing
Testing determines your drain field’s current capacity and identifies areas where effluent processing has failed due to saturation or contamination.
Drain field excavation
Carefully removes failed components while preserving usable portions of your system and minimizing disruption to surrounding landscape areas.
Advanced treatment system installation
Upgrades failing conventional systems with modern technology that processes effluent more effectively in challenging soil conditions.
Distribution system redesign
Creates proper effluent flow patterns using gravity or pressure distribution to ensure even waste processing throughout your drain field area.
Aggregate material replacement
Installs clean gravel and sand layers that restore proper drainage and create optimal conditions for long-term soil absorption.
Biomat restoration treatments
Break down clogged soil layers that prevent effluent absorption, often extending drain field life without complete replacement needs.

How leach field repair saves you time and money
- Avoid complete system replacement. Strategic repairs often restore function at a fraction of the cost of installing entirely new septic systems.
- Eliminate sewage surfacing problems. Proper drain field function keeps waste underground where it belongs, preventing health hazards and property damage.
- Restore property usability quickly. Fixed drain fields allow normal water usage and eliminate restrictions that failed systems impose on daily household activities.
- Meet regulatory compliance requirements. Properly functioning drain fields satisfy health department standards and prevent costly violation fines or legal complications.
- Protect groundwater quality effectively. Working drain fields filter effluent properly before it reaches underground water sources, maintaining environmental protection standards in your area.

When to call for leach field repair
Simple signs to watch for that indicate your system may need immediate attention before problems worsen.
Persistent wet areas
over your drain field during dry periods indicate soil saturation from system failure that requires professional evaluation and repair.
Sewage odors in yard
around drain field areas suggest effluent is surfacing instead of being absorbed, creating health hazards requiring immediate attention.
Indoor plumbing backups
despite recent septic pumping often indicate drain field failure that prevents normal effluent flow from your septic tank.
Failed percolation tests
during septic inspections show soil absorption problems that need professional drain field repair or replacement to meet code requirements.
Excessive vegetation growth
in drain field areas indicates system failure where nutrients are feeding surface plants instead of being processed underground properly.
Standing water or muddy conditions
over drain field locations during normal weather shows complete system failure requiring immediate professional intervention and repair work.
