Snowplow equipment operators should be educated about the underlying surface prior to beginning snow removal. Snowplow equipment should be fitted with Teflon runners or risers, which will help keep the snowplow blade from damaging the product.

For sites that will require the use of heavy-duty snowplowing machinery, install mow curb/strips prior to installation of vegetated paving mats. Vegetated surfaces should be depressed 1/2 inch below the top of the mow curb/strip to protect the product from the snowplow blade.

Do not use frozen materials or materials mixed or coated with ice or frost.

Do not build in freezing conditions.

Ensure proper drainage to avoid standing freezing water in contact with paving mats.

Do not use deicing agents that are known to damage concrete such as rock salt.
