Ideal for small repairs to manholes, sewers and general concrete structures. Advantages „ Unaffected by a wide range of acids, alkalis and industrial chemicals „ Superior chemical and physical bond to virtually all substrates, dry or damp „ Strengths in excess of the concrete to which material is applied. Excellent resistance to abrasion and impact „ Unaffected by freeze-thaw attack which eliminates problems often encountered with conventional waterbased materials „ Cured material provides a long lasting waterproof barrier „ No harmful vapours present Description Nitomortar EL-HB* is a three component system consisting of epoxy resins without solvents and a special blend of chemical resistant fillers. When mixed, Nitomortar EL-HB has a thixotropic consistency for easy hand placement, prior to finishing surface of the application with a trowel. Nitomortar EL-HB is simple and cost effective for overhead, vertical, horizontal patching and resurfacing to both dry and damp surfaces. The low odour, non-sag, and chemical resistant properties of Nitomortar EL-HB make the ideal material for long lasting concrete rehabilitation. Nitomortar EL-HB can be used in brick, block and precast concrete manholes. Nitomortar EL-HB provides a permanent impermeable, high strength, monolithic lining to the interior of manhole walls. To line concrete structures with an epoxy mortar, Nitomortar ELS is available as a spray applied lining system and Nitomortar EL is available as a trowel applied lining mortar. Contact Parchem for further information. Design Criteria Nitomortar EL-HB can be applied in sections up to 100 mm thickness in horizontal locations. The material should not be applied at less than 5 mm thickness. In vertical applications, the material should be “built-up” to a maximum thickness of 30mm. Greater thicknesses than those specified above can be achieved by the application of subsequent layers.
