· Construction method
- Injection by filler mortar exclusive pump, use clear water for mixing water.
- Worker adjusts mixing quantity according to specification.
- Once injection starts, quickly proceed with the work without interruption. Inject from only one side or end.
- Quickly clean the inside of the injection hose after injection.
- Do not recharge water nor remix after the hardening starts.
- Take special care during winter construction(below 5℃).
