TamCrete SSL

TamCrete SSL is suitable for initial ground support for temporary applications only and should be subsequently supported with traditional ground support techonlogies SCL for permanent applications.

TamCrete SSL is based on Acrylic resin and graded fillers and is not cement based or Polyurea based.

TamCrete SSL is versatile because it works often when no other means of support is available. This is mainly because it can be applied rapidly and safely, reinforcing the rock mass in the early stages using small compact spraying equipment.

TamCrete SSL’s structural support mechanism is considered to be particularly relevant in high stress situations in which some loosening will have taken place and in which on-going stress-induced fracturing does occur. TamCrete SSL penetrates into the rock mass along open fractures and joints and acts as a hard, rough gouge, filling and increasing the cohesion across the fractures. This strengthens the rock mass and limits the ability of the rock fabric to move. (Key block-interlocking). Due to the good adhesion capability of TamCrete SSL it is an excellent temporary support mechanism. The coverage with TamCrete SSL stops weathering and deterioration of fractures and preserves the excavation.

Due to the reduced amount of material that is applied savings are realised with operational effectiveness on logistics, application, etc.

TamCrete SSL is applied using highly mobile and light equipment without sacrificing spray production. TamCrete SSL can easily be applied in confined spaces and difficult access areas.

TamCrete SSL is highly adaptable and can be sprayed on humid and wet areas (not onto pressurised running water). Owing to TamCrete SSL’s fast strength gain ground support may be carried out right up to the working face.
