Green Rhino EnviroPad 5.0 - L31 Large 1370 x 910 mm Spill Mat - 31L Oil Capacity

EnviroPad 5.0 L31 Large Spill Mat

The EnviroPad 5.0 L31 is the large-format option in the EnviroPad range, measuring 1370 mm x 910 mm with a 31-litre oil capacity. It is the specification choice for high-utilisation plant on active construction and civils sites: large generators running continuous shifts, diesel compressors serving multiple pneumatic tool points, telehandlers, and tracked plant operating at fixed positions. At 31 litres, the L31 provides substantially greater capacity headroom than the M15, reducing replacement frequency on sites where equipment runs for extended periods. Like all EnviroPad generations, the L31 uses patented Neutroilize Smart Fabric Technology to convert oils, fuels, and hydraulic fluids into a permanently locked non-leaching solid, with Gen 5.0 adding full HVO and bio hydraulic fluid compatibility for sites operating low-carbon plant.

Why choose the EnviroPad 5.0 L31 Large Spill Mat

• 31-litre capacity reduces replacement frequency: On high-utilisation sites where plant runs continuously, the L31's larger capacity means fewer pad changes and less handling compared to the M15.

• Permanent hydrocarbon solidification: Oils and fuels convert to solid rubber on contact — no draining, no squeezing out under load, movement, or tracked vehicle pressure.

• Covers the footprint of large plant: At 1370 mm x 910 mm, the L31 accommodates larger generators, diesel compressors, and static tracked plant without leaving drip zones uncovered at the edges.

• Rainwater passes through, oil stays in: The mesh top wicks hydrocarbons inward whilst shedding clean water — no contaminated overflow, no hazardous liquid waste to manage.

• Jet-washable without contaminant release: Surface mud and site debris wash off cleanly without disturbing solidified hydrocarbons inside.

• Gen 5.0 HVO compatibility: Fully rated for HVO and bio hydraulic fluids alongside diesel, petrol, and motor oil.

• King's Award for Enterprise Innovation 2025: Independently recognised alongside Construction News Best Product Innovation 2024.

 Specifications

Compatibility

Who is this for?

The EnviroPad 5.0 L31 is specified by site managers, plant supervisors, and environmental coordinators on construction, civils, utilities, and infrastructure projects where large or high-utilisation plant operates at fixed or semi-fixed positions. At 1370 mm x 910 mm with a 31-litre capacity, it suits large generators running continuous overnight shifts, diesel compressors serving multiple tool points, telehandlers, static tracked plant, and dedicated refuelling bays serving medium and large equipment. It is the standard choice on sites where the M15's 15-litre capacity would require replacement too frequently to be practical.

Typical applications

• Placed beneath large generators during continuous site operations, particularly on infrastructure and civil engineering projects running 24-hour shifts

• Deployed as the primary spill control mat at a fixed plant compound or refuelling bay

• Used under diesel compressors serving multiple pneumatic breaking or drilling points simultaneously

• Positioned beneath telehandlers and other large wheeled plant at parking and service positions

• Specified at static tracked plant operating positions on major earthworks and groundworks contracts

• Used on rail, utilities, and energy projects where environmental compliance is subject to regular third-party audit

• Kept as a permanent provision at the welfare cabin fuel store on larger sites

How to use

1. Position the L31 on level ground directly beneath the equipment, label side up. The orange surround and carry handles indicate correct orientation.

2. Ensure the pad extends beyond the drip zone on all sides. The 1370 mm x 910 mm footprint is designed to cover the base area of large plant without leaving exposed ground at the edges.

3. Begin operations as normal. No activation or preparation is required.

4. The smart polymer core absorbs and solidifies hydrocarbon contact progressively. The pad thickens uniformly as capacity is used.

5. Check remaining capacity by pressing the pad surface firmly across its full area. Uniform thickening indicates the pad is approaching its 31-litre limit.

6. Move or store using the carry handles. Solidified hydrocarbons will not drain onto hands, clothing, or vehicle floors.

7. Jet wash to remove surface mud or debris. No contaminants will be flushed out.

8. Dispose of a saturated pad in a normal hazardous waste bin. No special COSHH handling is required.

Safety

• For incidental drips and refuelling spills only. Where a catastrophic spill is foreseeable, a bunded area with minimum 110% of the risk volume is required.

• Wear nitrile gloves when handling used pads in the early stages of saturation.

• Store unused pads flat, away from direct sunlight and heat sources.

• Do not use for AdBlue, chemical, or solvent spills. Hydrocarbon use only.

Maintenance

Inspect at the start of each shift by pressing firmly across the full 1370 mm x 910 mm surface to gauge polymer thickness. On high-utilisation sites running large generators or compressors continuously, check capacity every two to three days as a minimum. Replace when thickening is uniform across the full pad area. Jet wash surface debris as needed without concern for contaminant release. Store clean unused pads flat in original packaging away from heat. Keep one spare per item of plant for immediate replacement.

Frequently Asked Questions

Q: What plant types is the L31 designed for?

 A: The 1370 mm x 910 mm footprint and 31-litre capacity suit large generators (30kVA and above), diesel compressors serving multiple tool points, telehandlers, and static tracked plant. For plant with a footprint exceeding 1370 mm x 910 mm, or for a refuelling bay covering multiple large items simultaneously, the XL50 X Large at 1370 mm x 1370 mm provides a larger coverage area.

Q: How often will the L31 need replacing on a busy site?

 A: Replacement frequency depends on the leak rate of the equipment above it. The smart polymer swells to approximately twice its original thickness as it absorbs hydrocarbons. On a site running a large generator continuously, a practical inspection interval is every two to three days. When the pad has thickened uniformly across its full area, replace it before the next shift.

Q: What is the difference between the L31 and the M15?

 A: The L31 is 1370 mm x 910 mm with a 31-litre capacity. The M15 is 900 mm x 690 mm with a 15-litre capacity. Both use identical Neutroilize Smart Fabric Technology and Gen 5.0 HVO compatibility. The L31 is specified where the M15's footprint would leave drip zones uncovered, or where its 15-litre capacity would require replacement too frequently to be practical on a high-utilisation site.

Q: Can the L31 be used as the sole spill control measure at a refuelling bay?

 A: For incidental refuelling spills involving small volumes, yes. If the refuelling bay regularly handles drum quantities or if there is a foreseeable risk of a larger release, a bunded secondary containment area with minimum 110% capacity of the largest container at risk is required alongside the mat.

Q: Does the L31 work with HVO-fuelled large plant?

 A: Yes. Gen 5.0 is formulated to capture and solidify HVO alongside diesel, petrol, motor oil, and bio hydraulic fluids. The L31 provides compliant spill control for large plant that has transitioned to HVO without requiring a separate product.

Q: Why does the L31 not need a liner beneath it?

 A: The Neutroilize smart polymer converts hydrocarbons to a non-leaching solid on contact. Because the spill is solidified rather than held as liquid, there is no mechanism by which it can pass through the base of the pad. Liners exist to contain liquid — they are unnecessary when that liquid no longer exists.

Q: Can the L31 be driven over by heavy plant without releasing captured contaminants?

 A: Yes. The EnviroPad is constructed to withstand being driven over by tracked vehicles including excavators. Solidified hydrocarbons inside the pad cannot be squeezed out under vehicle weight, which is the critical failure mode of polypropylene absorbent products under the same conditions.

Q: How does specifying the L31 support Considerate Constructors Scheme compliance?

 A: The EnviroPad has been listed on the Considerate Constructors Best Practice Hub by Morgan Sindall. Specifying a product with that endorsement, alongside the King's Award for Enterprise Innovation 2025, provides principal contractors with a documented, auditable spill control provision that supports a high Considerate Constructors score on environmental management.

Q: How should a saturated L31 be disposed of?

 A: In your normal hazardous waste bin. No special COSHH handling is required because the hydrocarbons are solidified and non-leaching. For a pad of this size, fold using the carry handles before placing in the bin to reduce the volume for disposal.
