Pit Liners: Durable Containment Solutions
What are Pit Liners?
Raven American Tanks provides high-performance pit liners designed to safely contain water, chemicals, by-products, and wastewater in in-ground storage areas. Our liners protect pits used in industrial processes, remediation projects, energy operations, and commercial facilities where secure containment is essential.
With over 20 years of industry experience, we fabricate and install pit liners engineered for long-term durability, environmental safety, and regulatory compliance. For broader context on all available liner solutions, you can review our main service overview.
Why Pit Liners are Essential
Pit liners prevent contaminants from entering the environment by creating a secure barrier between stored liquids and soil. Industries rely on lined pits to safely manage:
- wastewater and runoff
- processed liquids and by-products
- oil remediation fluids
- chemicals and industrial residues
- temporary containment during operations
High-quality pit liners also reduce health risks, support compliance with safety standards, and prevent costly ground contamination events.
Applications for Our Pit Liner Systems
We design and install pit liners for a wide range of storage and containment needs, including:
- oil storage pits
- wastewater treatment pits
- industrial lagoons
- remediation pads
- processing dams
- temporary containment trenches
Each liner is customised to the dimensions, shape, and environmental conditions of your site.
Choosing the Right Pit Liner Material
Different pits require different liner characteristics depending on:
- type of stored liquid
- temperature exposure
- sunlight and weather conditions
- whether the pit is temporary or permanent
- chemical concentration
- size and depth of the containment area
PVC is commonly used for water and light chemical applications, while reinforced and heavy-duty membranes are recommended for oils, fuels, and aggressive substances.
Our team will help determine the ideal liner type based on your operational requirements.
Key Features of Our Pit Liners
Our engineered liners are developed for performance, strength, and longevity:
- puncture- and abrasion-resistant membrane material
- UV-stabilised for continuous outdoor exposure
- strong tensile capacity for large or deep pits
- flexibility for uneven ground or irregular shapes
- corrosion-resistant construction
- reliable temperature-variation performance
- lightweight materials for easier installation
These features ensure long-term containment even in demanding industrial environments.
Custom-Fabricated Liner Solutions
Every pit layout is unique. Raven American Tanks custom-cuts and welds geotextile sheets to create liners that match any pit shape, footprint, or depth.
We can also fabricate and install liners for:
- large-scale containment areas
- multi-section pits
- deep excavation sites
- irregular or non-standard geometries
If you are planning a pit reline for a large surface area, we can prepare and install a tailored solution onsite.
Maintenance-Free Performance
Our pit liners are designed to require minimal maintenance. Their membrane structure maintains flexibility without thinning, peeling, or becoming brittle. This ensures long-term protection with low operational effort.
If an existing liner begins to show visible wear or deterioration, further details about repair solutions can be found in our guide to liner repair options.
Secondary Containment Pit Liners
For fuel, oil, and chemical tanks, we construct pits that function as reliable secondary containment systems. These lined pits capture spills and leaks, preventing contamination and providing a final safety barrier for high-risk operations.
Our secondary containment solutions are engineered to withstand sudden high-flow discharge, aggressive chemicals, and extreme environmental conditions — ensuring safe operation even in demanding industrial settings.
If your facility requires a compliant containment pit or a replacement liner for an existing structure, Raven American Tanks can design and install a custom solution tailored to your site requirements.
FAQ
1. What are pit liners and why are they used?
Pit liners are protective membranes that prevent liquids from seeping into soil or groundwater. They’re used in industrial pits, wastewater areas, and remediation sites to ensure safe containment.
What materials are pit liners made from?
Common materials include PVC, HDPE, LLDPE, and reinforced geomembranes. The best choice depends on chemical exposure, temperature, and pit conditions.
How long do pit liners last?
Lifespan varies based on material quality, chemical exposure, temperature, and UV conditions. Proper installation and routine checks significantly extend durability.
What can damage pit liners?
Sharp debris, aggressive chemicals, UV exposure, and poor installation can cause wear. Prevention includes regular inspections and choosing a liner designed for the pit’s specific environment.
