Drain Protection

EnviroproNZ has a full range of drain protection options to ensure nothing enters the Stormwater system from your site.
Drain guards should be considered in high traffic areas to prevent rubbish, sediment, and hydrocarbon runoff.
Drain mats are essential to ensure you can isolate a drain in the event of a spill.
We have economy options and heavy-weight options.
Available in multiple sizes.


An economical drain protection option is the nitrile drain mat. This cover has great resistance to oils, petroleum, and mild acids.  They can quickly be placed over the stormwater drain to temporarily stop or slow liquid spills from entering stormwater.

750 x 1000 x 1.5mm
1000 x 1200 x 3.0mm

Nitrile Drain Cover Code: CDRA002 for 750x1000x1.5mm
