Fibre-reinforced, acid-resistant, two-component, cementitious mortar for repairing and protecting sewerage systems. It can be applied manually or by wet spray. Sewament 100 is used for the cortical restoration of damaged precast or placed concrete urban water purification system structures and sewerage systems. Sewament 100 is made up of pozzolanic reacting hydraulic binders, selected graded aggregates, special water retaining additives, synthetic fibres and a liquid form component based on acrylic polymers in water dispersion. Sewament 100 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 100 mixed with water becomes a thixotropic mortar, fast-setting and hardening, easily workable manually and with a wet spray machine. Sewament 100 can be applied, maximum 35 mm per layer, on the substrate which is sufficiently uneven (roughness not less than 5 mm). Thicker layers must be applied in several coats. 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.
Consumption approximately 21 kg/m2 per cm of thickness.
