Advantages of the extended injection winder D18 CF IR:

Wall dryers conventional type with inserted in holes bottles or the well-known impact or screw packers are often uneconomical, as these methods can not safely and reliably hydrophobic a wall in its full depth even under high pressure compression. This is due to the length and design of the wrench and screw packer, because all have one design feature in common: they simply represent only a relatively short tube, at the end of the hydrophobic liquid with more or less high pressure unintentionally leaking, hoping penetrate as far as possible into the wall depth. The lamellar packer D18CFIR with injector infusion tube (IR) ensures optimal penetration of the grout into the masonry. On the injector coupling side are markings which show that when they are set up, the spray holes alternately run 60 ° around the central axis and thereby ensure the best possible penetration in the dust-free borehole. The perforated infusion tubes (IR), which are drilled into the borehole depending on the borehole depth (masonry thickness), ensure a uniform distribution of the injection medium over the entire horizontal cross-sectional area. The grout can be injected into hollow, fissured and / or multi-shell masonry without the need for prior cavity filling.

Description of the extended injection winder D18 CF with open tip:

Drilling is a horizontal row of boreholes at a distance of 10-12cm, hole diameter 18-20mm, hole angle 10-15 ° downwards. The borehole depth results, taking into account the drilling angle, the reduced by 5cm wall thickness. The available lengths correspond to the common wall thicknesses. The IR can be easily adjusted by shortening. The so-called technical length is the length from the end ring of the injector to the leading edge of the IR stopper. The diameter of the D18 CFIR is such that even with a larger drill hole depth, the drill does not run away in an uncontrolled manner. The integrated spring-loaded check valve prevents the injected agent from escaping again.
The injector is structurally constructed so that the press connection can be separated safely when needed. That After fulfilling its function, the injector can be cut flush with the surface and remain in the object together with the IR.
For a secure hold in the wall is a prerequisite that the borehole is accurate, free from dust and deep, and the injector is used properly and far enough. For this we strongly recommend our impact aids.
