Bossong plastic sleeves with thread ends for continuous protection system; nylon insulation washer; metallic pipe fittings drilling machine/BOS TP plastic sleeves.

Highadhesion epoxy resin for heavyduty fastenings for use in different base materials as concrete, solid masonry and wood. This Bossong resin can be used also with wet concrete and flooded hole including underwater fixing (reduction of the recommended loads of 20%). Suitable for electrically insulated fastening. It has longterm resistance to hydrolysis. Excellent for applications with reinforced bars. Thixotropic consistency. The resin, due to its strong adhesion value and the ease with which it penetrates holes and hollow areas, permits secure fixing without expansion and so without stresses in the base material. It does not need premixing, the resin and hardener are only mixed during extrusion in the special mixer. It can also be used for repair and refilling. SERVICE TEMPERATURE RANGE Between 40°C /+ 40°C with T°max long period of 24°C and 40°C/+80°C with T°max long period of 50°C (ambient temperature after installation).

There are certainly technical and theoretical reasons determining whether an anchorage should be realized with resin or grout. However, in the practical application it is not so easy to define such limit, because of many factors, such as the compatibility with the original materials or simply feasibility problems during the execution. Significant parameters for choosing the type of anchors are type of substrate anchorage length hole diameter setting time and fixing mode waiting times for the loading of the anchorage The thixotropic consistency of the resin, that is useful to prevent from excessive spreading in the interstices of historical buildings, complicates the deep extrusion stage and limits the anchorage length in comparison with the application where the injection is realized with grouts.

Cooperation with the designer The characteristics of Bossong anchorages are defined on the base of the specific parameters of each single project, as well as the dimensions of the hole they must be embedded in, that depend on the type of material constituting the substrate. The change of information relating to the knowledge of the building’s state of preservation and of the aims of the provided interventions, drawings and pictures, the pattern of cracks and deformations, as well as the design of interventions, are very important to define the type of anchor that better fits the application and also to evaluate the intervention from the economic point of view. Tests in place The need to give to design engineers the possibility of an assessment of the behaviour of injected anchors in a particular application and in a specific setting has lead Bossong to equip its technician with a mobile instrumentation that allows the execution of onsite tests.
