Insulating dams and water tanks are important safety structures in underground mines. They require effective sealing due to constant contact with mine water and hydrostatic pressure.
Sealing materials:
FLEXICOVER — elastic spray membrane
a two-component, mineral-organic membrane for spray application. Creates gas- and water-tight insulation. Component A (dry) is a cement-based powder mix, Component B (wet) is aqueous polymer dispersion. Key properties: elasticity (high tear resistance), tightness maintained even with significant displacements, excellent adhesion to rock, concrete, steel, and wood, efficiency up to 200 m² per ton, fire-retardant.
Applications:
- Sealing roofs and sidewalls against water and gas leakage
- Protecting rock against weathering and crumbling
- Sealing insulating dams in old workings corridors
- Membrane coating working with bolt support
- Anti-corrosion protection of metal and concrete surfaces
- Waterproof insulation of underground tanks
Sealing method selection depends on structure type, water pressure, mine water chemistry, and required insulation durability.
