Two-way slope plates (counter-slope plates). They are designed to shape a two-way slope (counter-slope) on a flat roof of any inclination.

• Compressive stress at 10% relative strain: ≥70 kPa
• Tensile strength perpendicular to the surface: ≥15 kPa
• Water absorption by short duration immersion: ≤1.0 kg / m2
• Water absorption with prolonged immersion: ≤3.0 kg / m2
• Compressive force under a point load giving a 5 mm deformation: ≥650 N
