DEFENCELL Prole 300
Introduction
The DEFENCELL Prole 300 Protection System is a textile,
cellular, containment system which can be lled with
various materials (sand, gravel, soil and small rocks) to
build a variety of structures for perimeter security and
HVM protection.
Site Preparation
The ground should be level and compact to CBR value
of <5%. Where soft spots occur (CBR value of >5%)
the material will be excavated and replaced with 6F1
material compacted in 150mm layers. If the soft spot
locations are extensive, the material will be tested for
its CBR value. In addition, a trial pit will be excavated
to a depth of 1.5m and the sub-strata re-examined and
tested for its CBR value. Appropriate remediation of the
soft spot will be determined by the engineer.
DEFENCELL is to be lled using suitable granular ll with
a maximum stone size 40mm with no clays.
Landscape and Ecology
The designer should ensure that the berm proles takes
into account the following local material (soil) properties
and environmental conditions:
• Compaction: the consolidation of soil (under its own
weight) overtime.
• Erosion: the carrying away or displacement of solids
through weathering or living organisms.
• Slump: gravity causing material to slide down slope.
• Stability: the consistency of the berm form under
loading and over time.
Construction time
A team of four on an average 8 hour shift, with a 16T
excavator with 1m3ditching bucket plus operator, may
achieve the following:
Using the frame method
(Using two Prole frames)
Can complete 25-35 linear metres per shift.
(Not including landscaping.)
Note: These are a guide to installation of Prole300. The
production rate will increase or decrease depending on
the following:
• Distance excavator has to haul the ll
• Type of excavator used and bucket capacity
• The ow and size of granular ll used
• The experience of the excavator operator
• The climatic conditions
• The number of teams available
• Number of frames or pins available
Using the pin method
(Using enough pins for two panels at once)
Can complete 10-15 linear metres of Prole 300 per shift.
(Not including landscaping)
Installation
Prole 300 should be installed on compacted level
ground as per instruction above with consideration
given to drainage. The installation of Prole 300 can be
achieved in six stages:
Stage 1 - Panel Placement
The base layer of any Prole 300 PAS 68 design is the
P300:11. Identify the panel by its label which can be
found on either end.
Once the correct Prole 300 is selected, build the
corresponding Prole 300 frame by following the Frame
Installation Guide and position it on your building
site with the long side along the direction of your
construction.
Next identify the female end of the Prole 300. The
female end of a P300:11 has 11 cells while the male end
has only 10 cells.
Start with the labelled corner of the female end, lift the frame
up and place the corner cell onto the two corner pins.
