Every industrial facility deals with spills. Whether it’s hydraulic fluid under a press, coolant on a machine shop floor, or a chemical leak in a processing area, the speed and completeness of spill containment determines cleanup cost, downtime, and regulatory exposure. Sorbent pads are the frontline tool for controlling liquid spills at the source — and Wi-Supply stocks them in wholesale quantities for Canadian facilities that can’t afford to run out.
What Are Sorbent Pads?
Sorbent pads are flat, absorbent sheets engineered to capture and hold liquids. They’re made from polypropylene or natural fibre materials that absorb fluids on contact and resist dripping even when saturated. Unlike cotton rags — which spread a spill as much as they absorb it — sorbent pads are designed to lock liquid in and allow safe single-handed disposal.
Pads come in three formulations matched to what they’re absorbing, and choosing the right type is as important as having pads on hand at all.
Types of Sorbent Pads
Universal Sorbent Pads — Grey
The most widely used type across Canadian facilities. Universal pads absorb oils, coolants, solvents, water, and most non-aggressive chemicals. Grey colouring indicates “universal” in the standard colour coding system. These are the correct choice for general maintenance areas, loading docks, and anywhere liquid type is variable or unknown.
Oil-Only Sorbent Pads — White
Hydrophobic (water-repelling) construction absorbs petroleum-based fluids — oil, hydraulic fluid, fuel, and lubricants — while repelling water. White pads float and stay absorbent in wet environments, making them the right choice for use near floor drains, on water surfaces, or in areas where rainwater or wash-down water is present. Using universal pads in these situations fills their capacity with water, reducing oil absorption.
Hazmat Sorbent Pads — Yellow
Built for aggressive and corrosive chemicals — acids, bases, and unknown substances. Chemical-resistant construction handles materials that would degrade standard polypropylene pads. Yellow colouring signals hazmat duty and helps ensure pads are used and disposed of correctly under your facility’s safety protocols.
Sorbent Pad Applications
Machine Shops and Manufacturing
Coolant and hydraulic fluid leaks are constant in machining environments. Keeping pads staged at each machine dramatically reduces cleanup time and prevents slip hazards from spreading fluid. Oil-only pads are typically the right choice where coolant is water-based and oil leaks are the primary concern.
Maintenance and Repair Operations
Fleet maintenance shops, equipment service bays, and facilities maintenance teams use sorbent pads during oil changes, filter replacements, and hydraulic line work. Universal pads handle the mixed-fluid environment most MRO operations encounter.
Chemical Processing and Laboratories
Hazmat pads belong in any area where aggressive chemicals are handled. Canadian environmental regulations require appropriate containment materials for chemical storage and handling areas — hazmat pads are a low-cost part of a compliant setup.
Spill Response Kits
Sorbent pads are the primary fill item in spill response kits. Whether you’re building your own kits or restocking existing ones, buying pads in bulk from Wi-Supply is more cost-effective than purchasing pre-packaged kit refills.

Buying Sorbent Pads Wholesale in Canada
Running out of sorbent pads during a spill is not an option. Wi-Supply maintains Canadian inventory of universal, oil-only, and hazmat pads so orders ship same day and arrive within two to five business days across most of Canada. Volume pricing scales with case and pallet quantities — contact us for a standing order arrangement if your facility runs through pads regularly.

Frequently Asked Questions
What’s the difference between universal and oil-only pads?
Universal pads absorb water and oil-based fluids. Oil-only pads repel water and absorb only petroleum-based liquids. Use oil-only pads where water is present to preserve absorption capacity for oil.
How many pads should I keep on hand?
A common guideline is to keep enough pads to absorb the largest container of liquid in the area, plus 20% extra for a secondary incident. For regulatory compliance, consult your provincial environmental health and safety requirements.
Are used sorbent pads hazardous waste?
It depends on what they’ve absorbed. Pads saturated with regulated materials must be disposed of as hazardous waste in accordance with Canadian environmental regulations. Consult your provincial guidelines or waste management provider for disposal requirements.
Can sorbent pads be used in floor drains?
No — pads are for surface containment, not drain blocking. Use drain covers and plugs for drain protection. Sorbent pads used near drains help contain liquid before it reaches the drain.
