Our Septic System Services

New Septic System Installations

New construction and undeveloped rural properties often require a complete septic system installation. High Grade Excavation provides excavation and site services for new septic projects, including tank excavation, septic field preparation, pipe trenching, distribution-area preparation, aggregate placement, backfilling, and final grading.

We work with homeowners, builders, contractors, and rural property owners to prepare the site for a properly planned septic system. Before installation begins, confirm the required design, approvals, system location, and inspection requirements for the property.

Septic System Locates

Finding an existing septic system is important before landscaping, excavation, construction, driveway work, additions, pools, drainage work, or property improvements. High Grade Excavation can help locate septic tanks, access points, pipe routes, distribution areas, and septic fields using available records, site information, visible clues, and careful excavation where required.

A septic locate may help identify the system layout and improve planning for future work. Existing systems can vary significantly, especially on older properties. A locate is not automatically a certification of system condition, capacity, compliance, or remaining service life.

Septic Tank Excavation and Access

Septic tanks require safe and practical access for inspection, pumping, maintenance, repair, and replacement. We can excavate around tanks and access points, expose buried components, improve the surrounding grade, and prepare the site for related septic work.

Do not enter a septic tank or confined space. Tank access and inspection should be completed by properly qualified professionals using appropriate safety procedures.

Septic System Repairs

Septic problems can cause slow drains, sewage odours, wet areas, surface pooling, unusually green grass, or wastewater backing up. High Grade Excavation provides excavation and site work for septic repairs after the problem has been assessed and the required repair has been determined.

Repair work may include exposing a tank or pipe, repairing or replacing damaged lines, correcting drainage around the system, improving access, repairing a distribution area, replacing unsuitable material, or restoring the site after the work is complete. The appropriate repair depends on the system design, the location of the failure, the soil, the age of the system, and the applicable requirements.

Septic System Upgrades

Older septic systems may need an upgrade to improve performance, increase capacity, correct drainage issues, or support a renovation, addition, or change in property use. An upgrade may involve tank access improvements, pipe replacement, distribution changes, field improvements, additional treatment components, or related excavation and grading.

We can complete the excavation and site preparation needed for an approved septic upgrade. The design and approval requirements should be confirmed with the appropriate septic professional or authority before construction begins.

Septic System Replacements

When a septic tank, pipe, field, or other system component has failed beyond practical repair, replacement may be required. High Grade Excavation can excavate the existing system, prepare the area for replacement components, remove or manage unsuitable material, install approved materials as part of the project scope, and restore the property after completion.

A replacement system must be planned for the specific property. Soil conditions, lot size, setbacks, grade, water table, system capacity, and local requirements all affect the final design.

Septic Field and Drainage Area Preparation

The septic field, also called a leach field or disposal field, is the area where treated effluent is distributed into the soil. Proper preparation requires attention to elevation, soil, drainage, pipe layout, aggregate, compaction, and the approved system design.

We can prepare septic field areas, excavate distribution trenches, place approved materials as specified, complete backfilling, and grade the property after installation. The final design and material requirements depend on the site and approved septic plan.

Septic Pipe Trenching

Septic pipes connect the building, tank, distribution components, and field. We can excavate and prepare pipe trenches with attention to route, depth, grade, access, and connections. Proper trench preparation helps support the planned system layout and reduces the risk of avoidable settlement or drainage problems.

Septic Site Grading and Restoration

After septic work, the property may require final grading, backfilling, drainage improvements, topsoil placement, or restoration. We can shape the site to help direct surface water away from the septic components and nearby buildings while preparing the area for future grass, landscaping, driveway work, or other improvements.

Septic Services for Residential, Rural, and Commercial Properties

High Grade Excavation provides septic excavation and site services for new homes, existing residences, cottages, rural properties, farms, commercial buildings, and new developments. We work with property owners, builders, contractors, septic designers, and other project professionals.

Every septic project is different. The correct approach depends on the approved design, soil conditions, groundwater, property grade, system age, access, lot layout, and local requirements. We will review the excavation and site-work scope with you before starting the project.
