The foam is obtained after mixing component A (aqueous solution of phenolformaldehyde resin) and component B (aqueous solution of organic and inorganic acids).
It can be applied by spraying (components volume ratio 2:1) or by regular foaming (components volume ratio 4:1).
Minoterm can also be used to build or seal insulation and ventilation dams.
The high-strength Tekflex membrane was originally developed according to the TSL (Thin-Sprayed-Liner) technology to serve as an alternative to steel mesh and shotcrete for mining projects. Today, the Tekflex family has expanded and covers many more applications in the civil and tunnelling sectors.
Tekflex products are based on mineral materials with special additives or polymers to achieve sufficient rigidity or required flexibility depending on the type of the application. With just a few mm of thickness, the Tekflex membranes represent an effective, low-cost solution for changing the mechanical parameters of the lining or increasing impermeability.
Fibre reinforced, this product offers strengths over 55 MPa and can be used in conventional, dry-process shotcrete equipment. It is ideal where immediate structural strength is required.
Tekcrete™ Fast M was developed in response to customer demand for a shotcrete with effectively immediate strength on application. The product can be used with or without steel or polymer mesh, although the mesh will provide additional tensile and flexural strength. Binding broken strata together for better structural integrity, Tekcrete™ Fast M can be used anywhere in a mine where conventional shotcrete is used and as with any coating or sealant.
