Experience of more than 37,000 repaired manholes, pumping stations and other drainage systems with a total coating area of more than 500,000 m² worldwide
Three layer coating systems protected by several patent laws valid worldwide, based on a systematic coating of polymer compounds, which give a unique structural stability and adhesive strength ("Stress Skin Panel Effect").
Use of a polyurea material for the barrier layers and polyurethane foam for the filling layer (2k system).
The three layer coating system is in a position to prevent the infiltration of ground and stratum water, reprofile the surface of the structure to be repaired and/or sealed, and act against exfiltration from the structure at the same time.
The unusual colour was consciously chosen to guarantee optimum reflection of incoming light in the structure.
The repair is carried out in a trenchless procedure, and therefore contributes to the work being carried out with as little disturbance as possible to the environment and the surrounding area.
A 2 m deep manhole with a one metre diameter can be completely repaired within one hour, and can be used again immediately after the repair.
SpectraShield was developed in order to be the most economical, even in cost competition with the other main coating systems used (liner, coating and concrete rehabilitation).
SpectraShield is 100% reliable in the elimination of rehabilitation problems, which are caused by VOC (volatile organic compounds in accordance with the Code of Federal Regulation (CFR) 40, part 51.100(s), US EPA).
Can be used in almost any type of structure and surface.
Restoring the structure surfaces present before the repair.
Very short gel and drying times of materials.
Extremely high tensile strength and elasticity of the materials.
Extraordinary chemical resistance and widespread temperature range for use (-40°C to +175°C short term).
Main areas of application are sewerage structures in the domestic sewerage network, and manholes, pumping stations, filter basins, sedimentation or discharge basins.
