Fosroc Supercast Predimax Injection Hose comprises of a doublewalled, patented PVC hose specially formulated to be durable, robust and fully resistant to continous immersion in ground water, saline, sewage, alkalis, acids, petrol, diesel and alcohol. The hose has exit openings (slots) for the pressure-fed injection material. Openings of the inside hose and the those of the outside hose are staggered with respect of each other to prevent cement paste from entering the injection hose during concrete placement.
Available in P11 (for general use) and P19 (for tunnels or large voids in concrete) sizes, supplied in kits - please see Kit Contents below.
Accessory pack also available.

Application Notes
- Installation, injection, reinjection and selection of materials should be conducted by a Fosroc Approved Applicator
- The concrete should be a minimum of 28 days old prior to commencing injection
- The Supercast Predimax Injection hose systems consists of a suitable length of hose plus inlet and outlet vents. These vents allow for injection and each vent is of a different colour (White/Red) for ease of identification
- Overlapping of injection hose length should be approximately 100-150mm with subsequent hoses placed between 50- 80mm of each other
- Place in the middle of the wall. Where walls are wider than 600mm, the hose shall be placed at a maximum 250mm from the water side. In all cases ensure that the hoses are embeded at a minimum distance of 50mm in concrete
- Fix the injection and vent hoses to the substrate with hose clips and accessories as supplied. Fixing shall be at 200-250mm centre to centre, to ensure that the hoses do not float in the fresh concrete during casting process
- When injection needs to be carried out, locate the red vent hose, remove the sealing cap and fix suitable injection nipples and accessories. It is imperative that the following steps are followed in the listed sequence:
- Fill the hose with injection material using injection pumps until flow is observed at the other end (white hose)
- Plug the end
- Pressurise the Supercast Predimax Injection Hose
- The system will allow injection of Polyurethane (Nitofill WS60, Nitofill UR63), epoxy resin (Nitofill LV) cement suspensions (Nitofill CEM) and polyacrylate gels
