Modular systems
Advantages
replacement
worn/damaged turf can be removed or replaced with mature turf
Transportability
modules can be moved in and out of venues easily and quickly
drainage
increased drainage channels reduce water logging and clogging of the rootzone
Aeration
air reaches the rootzone from below
encouraging deep strong rooting
light and shade
light levels can be controlled
description + development
individual trays which can be removed from the venue + replaced
multi-functional stadia
2 main companies
Inscapes
Strathayr
both work on the same principle
reasons for development
modules can be grown specifically with a chosen
rootzone
grass seed mix
root reinforcement materials
Fibresand
Fibre-elastic
Desso/SISGrass
system is moveable, interchangeable + replaceable
easily held by forklift
transported by lorry from nursery to storage site
high drainage capabilities
healthy grass development
long term sustainable growth
optional air movement
hot, cold, blowing or suction
Construction and specification
construction
involves growing natural grass on individual 1.17m square trays which link together
each polythene plastic tray is 1.4m² in area and 28cm deep
drain and air outlets are located throughout the bottom of the tray
increases aeration + moisture removal
Spec
1.17m X 1.17m X 28m
made of high density polythene
drainage outlets located throughout the bottom of the modules
sides fold up during construction
fold down after establishment
weighs between 300 - 500kg
depending on rootzone make up and moisture content
Difference in the depth of the profile in the traditional field system vs module system
reduced depth allows for
reduction in materials
smaller mass to heat, drain and transfer gas
choice of rootzone is important for reduced depth
excessive moisture retention can cause
limited root growth
poor microbial activity
poor nutrient uptake
Drainage + Irrigation
pipes can be placed below construction
irrigation lines placed under trays
pipework is accessible if needing repairs
On-going development
continual research into maximizing multi-function venues
Tottenham Hotspur
plans for a retractable pitch
the pitch will be on top of an artificial surface
in 3 long trays
will retract under the south stand
dates back to early 1990's
first high profile modular turf field was installed for the men's world cup football matches
Pontiac Silverdome 1993
Disadvantages
advantages can only work if they can be applied
to be able to move trays there must be a large storage area
need to move a large number of trays to move one tray
limit in maintenance due to rootzone depth
