FLOW Mortar Bag

FLOW Mortar Bag

Conventionally, brick and mortar were used for pipe laying works in parting work involving injection of filled Air Mortar. However, this construction method had problems in working time and strength.
The FLOW mortar bag developed by TAC Corporation has a big bladder structure, and it is used by attaching it to the FRP pipe at the partitioning position.
This system can do partitioning work easily by leaving filled mortar or by adding plastic reinforcing agent and injecting it into the bag
