PaveDrain Manufacturer Warranty
Ernest Maier in partnership with PaveDrain is proud to offer the only manufacturer warranty for a permeable pavement stormwater BMP (best management practice).
3-Year Manufacturer Performance Warranty: Surface infiltration ≥500 in/hr
If after maintenance PaveDrain surface infiltration is <500 in/hr we will clean to perform above this benchmark.
- Anytime within 3 years your installed PaveDrain system will infiltrate water according to the ASTM C1701/C1701M-09, or C1781 test at or above 500 in/hr.
- Result is the average of 3 representative test sites: One chosen by manufacturer, one chosen by owner, and one chosen jointly.
- Maintenance: Recommended maintenance process should be followed as per most recent relevant manufacturer guidance at the time of installation
- Cleaning must occur at least every 2 years, or when 75% of the surface area falls below 100 in/hr
- Excessive build-up of organic debris (leaves, lawn clipping, etc) require more frequent maintenance cycles, including sweeping.
- Failure to follow these maintenance guidelines will nullify this warranty
- Additional conditions as below
Extended 6-Year No-Maintenance Warranty: >8 in/hr always
- Anytime within 6 years your installed PaveDrain system will infiltrate water according to the ASTM C1701/C1701M-09, or C1781 test at or above 8 in/hr.
- Result is the average of 3 representative test sites: One chosen by manufacturer, one chosen by owner, and one chosen jointly.
- No maintenance or cleaning required
- Additional conditions as below
Fine Print for both
- Proper Installation: Installation must be performed by a licensed, and PaveDrain-certified contractor and follow manufacturer’s guidance
- Base compaction in 6”-8” lifts
- Proper use of geotextiles and geofabrics
- Open joints
- Use
- Warranty is voided if pavement surface is used to store loose aggregate (sand, stone, mulch, soil, etc.)
- Plowing should be done with a rubber tipped blade / raised blade
- Limitations
- Warranty does not cover blocks that are chipped, damaged, cracked or suffer some other cosmetic issue that do not impact stormwater performance.
- If heavy vehicle traffic is expected, use PaveDrain HD blocks
- Warranty is only available for block purchased directly from Ernest Maier or its subsidiaries beginning January 1, 2022
- Applies only to contiguous areas larger than 300 SF
- Warranty does not cover blocks that are chipped, damaged, cracked or suffer some other cosmetic issue that do not impact stormwater performance.
FAQ
You say expect 1600 in/hr of surface infiltration, but are only guaranteeing 500 in/hr?
500 in/hr is above what any of our competitors will even realistically claim under ideal conditions. We chose 500 in/hr so you would feel comfortable that our system would outperform everything else on the market.
Why 8 in/hr?
This is the standard that MDE (Maryland Department of the Environment) sets for permeable pavement/alternative surfaces to be credited as such.
Are we crazy?
Crazy confident.
