Gravel-Filled Reservoirs

Because Eco-Blox are 96% void space, they allow the reservoir to be dug to just the size

required for the water volume needed. Backfilling with gravel fills 65% of the reservoir

with stone, leaving only the 35% that remains between the stones available for water

storage. This means that a gravel-filled basin will need to be three times larger than an

Eco-Blox basin to hold the same volume of water. That's a lot more time, excavation,

additional soil removed, additional gravel to fill the hole, labor costs and cleanup.

For Larger Basin Volumes

For installations where a larger basin volume or a deeper basin is required, Atlantic offers

Pump Vault Extensions for both the PV1800 and PV2300. Each additional layer of Eco-Blox

increases the depth of your excavation by 17.5"; use one Extension for each additional layer.
