Fabrication and installation of the Geomebrane
Prefabricated panel sizes were determined by the location and
cross section of the river banks. Layout drawings of each section
were first made and approved so that each panel number
is located in its precise location on the river section.
For the river banks the size of the panels varied between 12 to
15 m width by 50 to 67 m length. The length was determined
by full canal section width so that only longitudinal cross channel
seams were used. This allowed for full double fusion field
seams an QC air channel testing across the new river section.
The lake bank section required panels 20 to 35 m in width by
50 m in length.
The prime contractor scheduled incremental canal sections
for preparation of earth works, lining installation and cover soil
placement at a one week basis. Immediately after positioning
the cross canal seams were made by dual track thermal fusion
bonding with air channel for testing. All field seams were tested
with air pressure direct after seaming. In addition all subgrade
preparation, panel placement procedures, welding, testing and
reporting was accomplished in accordance with SealEco QAS
procedures and under full third party CQA observation.
Construction Quality Control and Assurance
The fully designed and implemented SealEco Quality Assurance
System was made a part of the contract documents and
utilized to the full extent on the Kolubara project. The QAS was
comprehensive and included quality procedures from original
roll goods manufacture through cover soil or aggregate placement.
The QAS included the following:
QC Manufacture of rollgods, QC Fabrication of panels,
QC CCL Material and Placement, QC Subgrade Preparation,
QC Panel Placement and Thermal Fusion Field Seaming and
QC Cover Soils and Aggregate Placement.
Implementation of the QAS in the field and at the fabrication
plant was carried out by the third party consulting organisation
CIP, Institute for Transportation, Belgrade.
