How to use

Installation Procedures

1. Installation of Polyinject Hose PVC is preferably position in the middle of the substrate or if not possible, with a minimum of 100mm concrete cover from any outside edge.
2. The Polyinject Hose PVC must lie flat on the 1st concrete section with the hose clips at 150mm apart. If the concrete surface is rough, then the hose clip spacing need to be closer so the hose is touching the surface of the concrete.
3. The standard length of Polyinject Hose PVC, between injection points is approximately 10-12 meter. This will achieve the ultimate injection process.
4. At the injection point location where each individual hose length meets, an overlap of 150mm is required and with the two hoses laid parallel to each other at a distance of 30mm apart.
5. The injection points are to be installed in such a way as to allow access al all times.
6. Over length applications of up to 30 meters are possible but the correct installation procedures and use of Acrylic Gel injection material be used via a 2K Pump. Note: Please refer to the manufacturer’s installation procedures and guidelines (available upon request)

Simple injection Process

1. Check the continuation of the hose by flushing with water or with air.
2. The hose is injected via the injection point until traces of the injected material are discharged from the Vent end (opposite end of hose). This vent end is closed by means of an injection nipple as soon as the injected Material flows freely (without air pockets) from the vent.
3. The flow and extent of the inject ion material in the concrete joint s can be monitored during the injection Process by means of the inject ion pump’s pressure gauge if using a 2K pump.
4. The injection process is continued until constant pressure has been reached. Constant pressure indicates that the concrete joints are absorbing no more injection material and thus signaling the end of the process.
5. Any injection material still within the injection channel is simply flushed out by means of a water pump (2K pump Unit). Minimal pressure is required and it is simple and easy to achieve.
6. On completion of the flushing process, the injection channel is ready for future reinjections, if required
