Datasheet: P1 Data GB01
Notes
Composition and Environmental
Behaviour
Composition
70% polypropylene / 30% polyethylene.
Durability
The products are predicted to be durable for more than 25
years for non reinforcing applications, in soils with a range of
pH 2‐14 and soil temperatures less than 25 degrees C.
Chemical Resistance
Alkali ‐ Resistant to all naturally occurring soil alkalis.
Acid ‐ Resistant to all naturally occurring soil acids, (i.e. to
acids of pH 2).
Biological Resistance
Terram is unaffected by bacteria, fungi, etc. Since it is not a
source of nourishment, rats and termites will not eat the
product as food.
Reaction to Temperature
The tensile strength of Terram decreases with increase in
temperature, but recovers fully when the geotextile is re‐
turned to normal ambient temperature.
Exposure to Sunlight
Terram is delivered in polyethylene wrappers to protect it
from the harmful effects of ultra‐violet rays: it is recom‐
mended that it remains wrapped until it is to be used.
The unwrapped product shall be completely covered within
14 days after installation to avoid UV radiation exposure
For projects where prolonged exposure is inevitable Terram
grades with UV resistance to match the requirement are
offered. In these grades the UV light resistance is enhanced
by appropriate stabilisers in the polymers.

All other properties are identical to the corresponding stan‐
dard series Terram presented in the data sheet. Terram prod‐
ucts with enhanced UV resistance carry the suffix UV (e.g.
Terram 1000 UV).
Notes
1. The stated properties are family mean values of the ap‐
propriate tests derived over periods of time.
2. The mean tensile values quoted are the mean values in
either the length or cross directions, whichever is the
lower.
3. For a full description of the test procedures quoted please
refer to the specific methods of test.
4. Where widths or lengths greater than those supplied on
one roll are required, jointing is normally effected by sim‐
ple overlapping. However, depending upon application,
sub‐grade conditions, material loading, convenience and
cost, alternative methods (pegging, sewing, stapling or
gluing) may be used. Please refer to the Terram Jointing
Methods leaflet for more details.
5. As part of its continual improvement process Terram Ltd
reserve the right to change the properties listed on this
data sheet without prior notice.
