Our 22,5cm by 20cm Dammit clay drain mats are supplied in boxes of 12 and are ideal for use on standard square drains.
- Instantly seal a drain to prevent spilt oils and chemicals flowing into storm drain and out to controlled waters.
- Fit the contours of drains to create a complete seal on uneven or broken drains.
- Due to their flexibility you can easily plug misshapen drains.
- Treated with a formula which prevents mould growth and anti-freeze properties so the mat remains flexible down to -20°C.
