Flexible vinyl chloride sheet with excellent flexibility and processability<\/h4>\n\n\n\n

This is an impervious sheet made of vinyl chloride resin with excellent workability. It is flexible and can be installed anywhere. In addition, since the sheets can be thermally welded on site, they can be joined together in a watertight manner.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

Excellent physical properties<\/h4>\n\n\n\n

The physical properties of SANPVC sheets fully satisfy the voluntary standards for low elasticity sheets in the \u201cJapan Interceptor Engineering Association\u201d and the physical properties of soft PVC interceptor sheets in the \u201cLand Improvement Project Design Guidelines.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

Various processing and joining methods<\/h4>\n\n\n\n

On-site joining of impervious sheets is possible using adhesives as well as heat fusion welding using special machines such as self-propelled welding machines and hot-air welding machines. We can also provide pre-welding and cutting services according to the site conditions.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

End Fixing Method<\/h4>\n\n\n\n

The most common method of securing impervious sheets is to embed them by excavation backfilling. The impervious sheet is secured by digging into the ground to a depth large enough to withstand the pull-in load and thermal contraction. In addition, concrete or other structures are usually held in place with flat bars, etc., and then anchors, etc., are used to secure the sheet.<\/p>\n\n\n

Self-propelled welding situation<\/h4>\n\n\n\n

Water barrier sheets are joined using a self-propelled welding machine. Thermal welding can be done homogeneously and quickly.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

Manual welding status<\/h4>\n\n\n\n

A manual welding machine is used for detailed joining work. The sheet is heated by hot air emitted from the welding machine and crimped by rollers.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n
