Circumferential Seaming

TenCate patented circumferential seaming reduces the stress on the seams which allows for higher pumping heights and a higher factor of safety than longitudinal seams. When a Geotube® unit is being filled, the greatest stress goes across the fabric from side to side.  When longitudinal seams are used, the stress is pulling the seams apart as it is being filled. Circumferential seaming also allows for any circumference to be created without introducing additional seams.
