TP units must be able to be moved freely around
existing utilities. With a connected matrix of units this is
not possible. Units/cells are designed and tested as
stand alone (not interconnected)
Maintenance and repair
Every unit can easily be opened and closed without damaging the integrity of the system, even when the units are
No pavement lifting
Soil settlement and -expanding within the system will not
have any effect on the pavement.
To maximize soil volume or overcome (un)foreseen obstacles the system must be adjusted to every length preferable.
All materials are chemically inert to natural soil conditions.
100 years guarantee.
Specifications green infrastructure
Smallest penetrable opening Ø 33 cm. The smallest opening must be bigger than the maximum root thickness,
to prevent strangeling of the roots.
Maximum soil volume
Ca. 95 % of the system can be filled with soil (1-1,5 MPa
penetration resistance) and still leaving a 5 cm air layer on
top. Uncompacted soil will settle up to 25%.
Water- and air capacity
Within the TreeParker system the soil acts as one continuous natural soil volume, this will enhance root growth
because of good water and air penetration and diffusion.
High quality soil
The system is fillable with all kind of soils. No concession
needed on soil quality. The system does not impose
restrictions on the soil mix.

Stormwater retention and infiltration
TreeParker system are BMP stormwater management
systems. No open walls, uncompacted soil or open posts
which drains the water down directly and too fast. In TreeParker the soil and tree can take maximum advantage of
the incoming water, rain water and/or irrigation water.
The soil within the TreeParker system acts as an natural
filter (Phytoremediation). Polluted stormwater is filtered
and only clean water will recharge groundwater. Water is
not drained down directly through the system but will be
