One-component, fibre-reinforced, cementitious mortar for restoring and repairing sewerage systems. Sewament 10 is used for the cortical restoration of damaged precast or placed concrete urban water purification system structures and sewerage systems. Sewament 10 is made up of hydraulic binders, selected graded aggregates, special water retaining additives and synthetic fibres. Sewament 10 is resistant to the chemical aggression produced by sulphuric acid following the bacterial oxidization of the acid as the result of the anaerobic fermentation of civil and industrial liquids. Sewament 10 mixed with water becomes a thixotropic mortar, easily workable manually and with a spraying machine. Sewament 10 can be applied, maximum 20 mm per layer, on the substrate which is sufficiently uneven (roughness not less than 5 mm). If the thickness needs to be more than 30 mm, it is essential to insert a reinforced net appropriately distanced from the substrate. Finish the surface with a sponge float or with a flat trowel. If Sewament 10 is manually applied, always apply a Sewament 3 Primer, single-component cementitious mortar bonding enhancer, beforehand.
Consumption approximately 18.5 kg/m2 per cm of thickness.
