    Repeatable injection : After vacuum cleaning, the system can still be used for other purposes and repeated injections at any time.
    Detectability : The moisture absorption of the grouting tube before and after the injection can be measured by a simple and reliable method with strictness.
Safe and reliable : After more than ten years of application and laying experience in the professional field and successful grouting experience in domestic large and medium-sized projects, we ensure that we provide our customers with the most professional technology and the best performance products.
    Performance principle :
    During the concrete pouring process, when the external concrete pressure is applied, the rubber cover strip wrapped on the outer side of the grouting pipe is tightly attached to the injection discharge hole of the central shaft tube due to the pressure, thereby closing the entire system and preventing the concrete during the pouring process. The slurry is mixed into the grouting pipe.
    Specifications : Inner diameter : 8mm; Outer diameter : 20mm; Inner diameter tolerance : ±0.3mm; Length per roll : 30m
