Sprayed Concrete: An Interaction of Man, Machine and Concrete
In times of rapidly increasing mobility and limited space, the need for underground infrastructure continues to grow. Sprayed concrete has an important role in this trend. This method is economically outstanding and almost unlimited technically, making it the obvious answer to a lot of challenges.
Sprayed Concrete Explained
Systems: Sprayed Concrete Technology
Shotcrete Solutions
Sprayed concrete is a high sophisticated application technology. For that reason special admixture for water reduction (Sika ViscoCrete-SC), extended slump-life (SikaTard) and accelerating the shotcrete (Sigunit) are needed.
Equipment Solutions
For the application of shotcrete a wide range of different equipment (Aliva; Sika-PM) is ready for dry or wet application, convey in thin or dense stream method.
Fire Protection
Fire protection mortar protects concrete and steel from the effects of extreme heat. Structures requiring protection only need a thin layer to allow them to survive extensive fire stress and remain undamaged.
Waterproofing Systems
According to the required degrees of watertightness a tunnel structure has to be waterproofed. There are a number of possible solutions depending on the ground and substrate conditions, the water pressure and the water and design concept.
Injections Systems
Waterproofing of construction joints, cracks, damaged membranes and foundation pits as well as surface sealing of leacking concrete structures.
Repair and Protection
Repair and protection of concrete structures which have been damaged or which have deteriorated require professional assessment.
