DESCRIPTION

KÖSTER Injection Gel S4 is used for stopping active water ingress, to quickly seal joints and for curtain injection. The setting time can be adjusted between 20 seconds and 3 minutes by changing the added amount of the B component. By adding an organic dispersion to the B component (KÖSTER B+), the gel can achieve a particularly high flank adhesion on mineral substrates. The organic dispersion accelerates the gel by approximately a factor of 2 and significantly improves the elongation at break. The standard set is supplied as follows; A1 component: 20 kg, A2 component: 1 kg, B component (salt): 0.4 kg. All components can also be ordered separately. To increase the flank adhesion and improve the elongation and tear resistance, the B + component (dispersion) can be ordered separately. Colored versions of the gel can be made on site by the addition of separately supplied pigments.

For curtain injections, KÖSTER Injection Gel G4 is recommended. When using KÖSTER Injection Gel S4 as a curtain injection, it must be noted that the injection parameters (quantity of material per stroke, number of strokes, waiting times, pressure, etc.) must be changed and the injection theory presented in the training courses is not transferable. The KÖSTER Injection Gel S4 is resistant to pollutants commonly found in subsoil and building components; such as salts, etc.

AREAS OF APPLICATION

Water stoppers: In the event of heavy water ingress, injection solutions can be realized if the gel times are accelerated to a high degree. Joint injection in buildings, underground garages, bridges, and similar structures: Using KÖSTER B+ organic dispersion improves both the flank adhesion and the elongation at break, which especially makes sense when injecting joints. The reaction times are approximately halved in contrast to the standard mixture, but can still be controlled by the amount of salt. For joint injection a longer gel time is usually recommended. Sealing joints with KÖSTER Injection Gel S4 is typically done on building components in contact with soil for repair work to stop water entering from outside. Acrylic gel joint waterproofing must always be designed in such a way that the gel seal can not dry out, e.g. by using KÖSTER FS joint Sealant or KÖSTER joint tape 20. Curtain Injection: For the demarcation of curtain injections in the edge area, a more rapid gel time (for example into gravel) may be useful to avoid further outflow of the material. It would also be possible to adjust a lower penetration of average sands over a faster reaction time. In other cases it is recommended to use KÖSTER Injection Gel G4 with a particularly low viscosity and a standard reaction time of 4 minutes.
