Sump Lining System

This coating system provides a waterproof, anti-static, chemical resistant coating for sumps. The system can be applied for 4 different kind of sumps. The sump can be made from steel, fiber glass, concrete or brick. For different subsurface different primer must be used. The system can be reinforced with fiber glass sheet. The system is approved by the German Institute for Construction Technology (DIBt).

Structure of the lining system:

Schematic of the sump lining system

Surface Preparation:

The surface shall be solid, clean, dry and free of any hydrocarbon residuals.

Levelling:

Reprofiling. Cover the cracks and uneven surfaces with Epoflex® Klebmoertel.

Lining:

For each application a dew point distance of 3°C must be observed.

Primer:

Primer application depends on the subsurface. For proper adhesion special primer must be applied directly on the cleaned and solid underground surface.

Main structural layer on vertical surface:

Epoflex® DOM Spachtel is a 2 component (resin and curing agent) epoxy based conductive resin. Mixing ratio is 2:1 by weight. Apply approx. 3 kg/m2 which is 2 mm of thickness after drying. The material shall be applied with trowel or brush.

Main structural layer on horizontal surface:

Epoflex® DOM Guss is a 2 component (resin and curing agent) epoxy based conductive resin. Mixing ratio is 2:1 by weight. Apply approx. 3 kg/m2 which is 2 mm of thickness after drying. Pour the Epoflex® DOM Guss on the dome shaft floor and distribute it roughly. Due to its low viscosity, the material spreads by itself and the desired coating thickness is obtained automatically.

Installation note:

The above information is based on tests by approved institutes (e.g. TÜV Süd Germany) and many years of experience. As the lining performance depends on correct installation, we offer application courses for certified installers and installation supervisors and provide certificates which shall be renewed every 3 years.
