AERATION, IRRIGATION & DRAINAGE
Deep aeration relieves compaction
Waterlogging on grassed areas such as
parks, around trees in public spaces and
all types of sports pitches is often the
result of heavy compaction. The action
of normal aeration, use of machines and
foot traffic, over time can all contribute
to panning and poor drainage, depriving
grass and tree roots of oxygen and
nutrients. Deep aeration specialists
Terrain Aeration have been providing
a long-term solution to this for over
twenty-five years.
The Terrain Aeration’s Terralift machines
hammer a hollow probe one metre into
the soil using a JCB road breaker gun.
This is because the ground is usually so
compact at depth it needs the hammer
to break through). Once the probe has
reached one metre depth, compressed
air is released up to a maximum of 20Bar
(280psi), which is needed to fracture and

fissure the soil. The probe is withdrawn
and the process repeated using two-
metre centre spacings on a staggered
grid pattern - this means that each shot
interconnects with the previous ones.
injected which stick to the walls of
the fractures and fissures and, over
time, expand and contract with the
moisture content in the soil - similar to
“breathing” underground. Biochar can
also be incorporated which collects
contaminates in the soil structure. The
1½” probe holes created by the Terralift
machine are backfilled with Lytag
aggregate to provide a semi permanent
aeration/ventilation shaft, helping
to keep the whole aeration process
working. The Terrain Aeration process
is ecologically sound, there is no mess
and the deep aeration ensures good
drainage for many years ahead.

COMPACTION AND WATERLOGGING STOP PLAY.
DOWNTIME COSTS MONEY.
Terrain Aeration’s long-term treatment reaches
one metre deep where compressed air blasts the
compaction.
The soil is opened up for good drainage and a
healthy sward with minimum disruption.
We have been successfully aerating sports turf,
bowling greens, golf courses, parks, trees and
gardens for over twenty-fi ve years.
