Roll weights can be up to 35kg, hence appropriate equipment is required for unloading and handling.
PD1700 is supplied in packaging designed to protect from damage during handling and storage, and degradation as a result of UV exposure. PD1700 should be kept in supplied packaging until it is required for installation, and then covered within two weeks of installation.
JUTA UK PD1700 is primarily used for external tanking applications, forming a high comperssive strength void, providing a path of least resistance for water, which enables controlled drainage into outlets or connector pipes. PD1700 can be used in combination with GP gas/waterproofing barriers to provide both protection and drainage for external tanking application, ensuring the gas /waterproofing barrier remains intact and the system performs as intended.
PD1700 should be installed with the geotextile facing the soil/backfill, and the direction of the water flow. Rolls can be cut to size on site. PD1700 can can be held in place prior to backfilling with DS Butyl tape (50mm wide), or mechanically fixed in the in the absence of a gas/waterproofing barrier.
Adjacent rolls can be overlapped using the geotextile, secured with DS Butyl tape (50mm). Roll ends can be connected by simply butting the cuspate sheet together.
Connection to land drains/collection pipes is achieved by placement within the slotted area, or removal of the cuspated core, and wrapping of geotextile around the pipe. Care must be taken not to damage/cut the geotextile during core removal to facilitate connection.
Backfilling should proceed with caution to avoid undue stress on the PD1700. Compactive effort should be avoided within the first 100mm of the PD1700.
