Drain covers seal storm drains and prevent oil, chemicals, fuels and contaminated liquids from entering drainage systems during spills. They are used in industrial facilities, warehouses, fuel stations, loading docks and manufacturing plants. Also see Drain Filter Solutions.
Drain blockers are made from polyurethane, which provides a temporary seal against oils, chemicals, and hazardous liquids. Their flexible and reusable design makes them a practical part of any spill response plan. You may also need Chemical Spill Kits, Oil Spill Kits, and Spill Containment Pallets for complete spill response coverage.
Drain spill covers support EPA, NPDES, and stormwater pollution prevention regulations by preventing contamination before it reaches public drainage systems and water bodies. Available in 10 sizes from 6" to 54" for round, square, and rectangular drains.
Place the cover over the drain, press down — sealed in under 30 seconds. No tools, no adhesive. Reusable across multiple spill events. Request a Quote Today.

Measure the drain opening — polyurethane drain covers come in standard sizes to fit square and round drains from 30cm to 90cm. The cover should overlap the drain edge by at least 5cm on each side to create a proper seal. For non-standard drain sizes, Enviroguard can supply custom-cut covers.
Under 30 seconds. Place the polyurethane cover over the drain opening and press down — it seals to the surface immediately. No tools, no adhesive. After the spill is cleaned up, peel it off, wash it, and store it for next time. Keep one pre-positioned within arm's reach of every drain near your chemical or oil storage areas.
Yes. A drain blocker placed over a storm drain during a spill creates an instant seal that stops oil, chemicals, and fuel from entering the drainage system. Polyurethane blockers are reusable — peel them off after cleanup, wash, and store for next time. Keep one near every drain within 10 metres of your oil or chemical storage area.
