LW Re-inject Is one of the specially designed solid PVC injection pipe systems. It can be mounted on the internal cement joint, used to waterproof and seal any gaps and holes on the joint area.
1.Can pass leaking test
Can confirm the sealing property of the construction joint at scene
Grout only when the joint leaking
2.Hose can be unlimited re-injected
If there are still crack or new cracks, hose can be grouted again, effectively reduce the complicated process of changing tools
3.Rigid core Won't be pressed flat under concrete pressure so as to make the use of the grouting unobstructed
4. Resistance to chemical corrosion
Won't be corroded when contacting polyurethane, ethylene resin, epoxy resin or cement, the material is durable, Do not contain metal
Expediently placed in the corner, no need to cut and connect.
Subway, tunnel, Water and sewage treatment plants, Swimming pool and water amusement park, Nuclear power station, The dam, lock, canals, reservoir and ditch, Primary and secondary cofferdam facilities, Bridge, Commercial and industrial buildings, garage, stadium, Aquarium, tank and similar structure .
LW repeatable injection pipe installation length can reach up to 10 meters, which include the fiber reinforced PVC end. If you need longer, please contact Beijing Lang Wei times science and technology co.,ltd.;
In central parts, every 20 -- 25 cm, use special plastic clip or pipe clamp (see figure 1 and figure 2) to fix LW repeatable injection pipe on flat and smooth cement plane;
Cover at least 2cm cement overlay;
Not to install in ways of bend or limitation, and should not be connected in reinforcing bars as building support
Distance between two parallel injection pipes is at least 5 cm
Connect grouting pump at the end of the PVC emissions tube For future grouting, The fiber reinforced PVC pipe ends should be exposed to convenient, accessible place. Use terminal box, shoot to nail gun or directly extend fiber reinforced pipe to the cement external (see chart 3);
In many practical applications, it requires the injection pipe cross each other. The intersection parts must maintain close contact with concrete; Discharge outlet part can overlap (see chart 1);
Extend the fiber reinforced discharge outlet about 10cm into the box when junction box used.
Two models are alternative:
Gap between holes
LW 1 Used for all standard building joint;
LW 2 If need more long injection pipe according to design reasons or if the upcoming cement mortar (Portland cement and mortar mixture) grouting, namely, as to design and application problems, please call Beijing Lang Wei times science and technology co., led.
Stored in a cover of place, avoid oil, dirt, concrete rubble, etc. getting into the hose.
Quality guarantee period:Permanent preservation according to the recommended way, in the seal, original conditions.
