Corroded interior
The trap’s working surfaces, baffles, or connection areas are deteriorated, while the surrounding installation may still support a retrofit approach.
Custom retrofit solutions
Give a failing grease trap a new working interior.
A custom drop-in liner may offer a less disruptive alternative to complete removal when an existing interceptor is corroded, embedded, or difficult to access.
Why consider a liner?
Replacement without starting from zero.
Removing an old interceptor can mean demolition, excavation, plumbing changes, floor repair, and business disruption.
Where the existing installation and approving authority allow it, a purpose-built insert can create a new containment surface inside the original footprint. Pipe penetrations, baffles, and edge details can be incorporated around the project’s measured conditions.
- Custom fit for non-standard existing dimensions
- Potentially less demolition and site disruption
- New corrosion-resistant interior surface
- Useful for embedded or hard-to-remove units
A liner is not a universal repair. Suitability depends on the condition of the surrounding structure, access, connections, temperature, loading, maintenance needs, and local approval.
Concept illustration. Each liner is reviewed and built for the actual field conditions.
Good starting candidates
When a liner may deserve a closer look.
These conditions do not guarantee that a liner is appropriate, but they are common reasons to request an evaluation.
Difficult removal
The unit is recessed into a finished floor, built around equipment, or located where excavation and replacement would significantly interrupt operations.
Unusual footprint
The existing opening, pipe locations, or dimensions do not match a readily available replacement unit.
Help us evaluate it
Measurements and photos make the first review faster.
Start by documenting the trap after it has been safely emptied and cleaned by qualified personnel. Do not enter a confined space or handle hazardous waste to obtain measurements.
- Clear inside length, width, and depth at multiple points
- Opening, rim, lid, and surrounding floor details
- Inlet and outlet pipe sizes, locations, and centerline heights
- Baffle locations and any internal obstructions
- Wide and close-up photos showing corrosion or damage
- Project location and any known approval requirements
Liner project flow
From field conditions to custom fit.
Accurate information at the beginning helps prevent assumptions and identifies whether a liner should move forward.
Document
Send dimensions, pipe information, photographs, access details, and the trap’s known condition.
Evaluate
We review the geometry, connections, material needs, and project constraints.
Confirm
Open questions, final measurements, responsibilities, and approval needs are resolved before fabrication.
Fabricate
The liner is built to the confirmed specifications and prepared for the project’s installation plan.
