Cover that drain or start writing checks

Your risk of polluting a stream, river or lake is as close as the nearest storm drain. Spills escape through the drain to the groundwater and waterways. Hello, hefty fines.

The easiest, most cost-effective solution is to cover and seal the drain with a drain cover. Consider three points when choosing.

Ease of Deployment

The best drain cover will be tight-sealing and easy to use, whether it's for emergencies or left down for extended periods.

Ruggedness and Reusability

Only PIG DrainBlocker Drain Covers with DuPont Elvaloy have a specially formulated, two-layer design that makes them UV- and chemical-resistant, long-lasting, tight-sealing and extra strong to prevent tearing. Use indoors or out, with foot or light cart traffic. They can be removed, cleaned and stored for reuse.

Traffic Applications

For traffic from light vehicles to tankers, the tight-sealing PIG Drive-Over DrainBlocker is ideal. It's puncture- , UV- and chemical-resistant. It can also be removed, cleaned and stored for reuse.
