Installation Guideline
Under Sleeper Pads
for Steel Sleepers
1. Transport and Storage— Always transport in original packaging— Damaged packaging shall be immediately repaired (usingplastic foil and adhesive tape)— Storage should be in a dry environment in original
packaging— Protection from direct sunlight is preferred— Once the original packaging is removed, Under Sleeper
Pads (USPs) must be kept dry— Temperatures below -20 °C and above +50 °C should beavoided— Do not stack pallets and parcels— Under Sleeper Pads are subject to normal thermal
expansion/shrinking. This physical effect is completelyreversible— Storage conditions (and temperature) should match
installation conditions; in case of big temperature
differences between storage and production area, it’srecommended to condition/temper Under Sleeper Pads
for at least 24 h
— Usually padded steel sleepers are stacked on top of eachother and stored outside.
— The maximum number of sleepers with a weight of
300 kg per sleeper to be stacked: 10 (width of the spacer
min. 100 mm, see illustration on the right)— Attention has to be paid during transportation to avoid
mechanical damage

Spacer2. Adhesive Bonding of USPs
For installation on steel sleepers, the under sleeper pads
are delivered without a connection layer (flock or mesh), inorder to enable adhesive bonding.
2.Adhesive
The adhesive is provided with the pads by Getzner
Werkstoffe and is solvent-free. The safety data sheet andinstructions for use have to be taken into account.
Attention: Please note that in case of bonding the Under
Sleeper Pads with Diisocyanate containing bondingagents, staff needs to be trained and certified conform EUlegislation 2020/1149. More information you can find via
