Atlantic ECOBLOX - 74243 Manuel Du Produit page 4

Eco-Blox must be set on a level, tamped base. If the base of the excavated reservoir is not
firmly compacted or uneven, the blocks may shift under load, destabilizing whatever is set
on top of the reservoir.
Eco-Blox do not retain water directly, they must
be used with an impermeable liner, typically
45mil EPDM, which should be protected from
sharps in the soil, roots, rodent damage, etc.
Before setting the liner in the excavation, cover
the tamped base and soil sides of the excavation
with a layer of underlayment, then set the liner in
the excavation. Because all edges and corners of
the Eco-Blox are rounded, the Eco-Blox can be
set directly on the liner. However, because sharp
gravel and debris can sometimes fall into the
completed reservoir, a second layer of underlayment on top of the liner
before setting the Eco-Blox will ensure maximum security and longevity.
Eco-Blox are designed to support massive distributed loads of up to 7 tons without
collapse. However, point loads over 36psi can break individual ribs. For example, the
pressure exerted by a boot heel jumping down onto bare Eco-Blox may exceed 36psi. A 3"
layer of gravel over the Eco-Blox is all that is necessary to distribute loads sufficiently to
support foot traffic.
Eco-Blox in Pond-free Systems
The water stored in Eco-Blox reservoirs is typically accessed by the Pump Vault, a
reinforced slotted housing that shares the underground reservoir space and houses
pump(s) and plumbing. A single layer of Eco-Blox can be used with all Atlantic Pump
Vaults. Pump Vaults are taller than Eco-Blox so the pump inside will sit at the lowest
point in the reservoir. This will help protect the pump from running dry and maximizes
the usable volume of the reservoir.

For deeper reservoirs, PV1800/PV2300 Pump
Vaults and Extensions (PV18EXT/PV23EXT)
accommodate multiple layers of Eco-Blox. Each
Pump Vault Extension equals the height of one
Eco-Blox. Use one Pump Vault Extension for
each additional layer of Eco-Blox.
