GIAN Anti-slip. Safety cast in concrete GIAN anti-slip formliners : attractive, thin texture mat adhered inside concrete mould GIAN is the name of the innovative texture mat from Compañero. This texture mat is easy to handle and can be used repeatedly. GIAN 2 sandblast texture The GIAN 2 sandblast texture was developed by Compañero especially for the concrete industry. The contra-sandblast texture in the mat gives the concrete an effective sandblast anti-slip effect after removal. From an environmental and technical perspective, the use of the GIAN 2 texture mat is preferable to blasting because no particulate matter is released during production and the top layer does not become porous due to sandblasting. The use of the GIAN 2 texture mat keeps the top layer of the concrete surface intact, making it less susceptible to moisture and dirt absorption. The GIAN 2 sandblast texture goes together excellently with our other sandblast products: GIAN 2S (square sandblast), GIAN 7 (dot sandblast), GIAN 8 (rib sandblast) and GIAN 9 (octagon sandblast).
