Sikaplan® WP 1100

Sikaplan® WP 1100 series of membranes are loosely laid homogeneous PVC-based sheet membranes for tunnel and below ground structures waterproofing. Several nominal thicknesses are available ranging from 1.5 to 3.2 mm. These membranes are manufactured with a yellow signal layer, which varies in thickness between less than 0.2 mm (HL2 type of membrane) to about 0.6 mm (HL type of membrane). Membranes are sealed by thermal jointing. The following membrane thicknesses are available:

• Sikaplan® WP 1100-15 HL (1.5 mm total nominal thickness, 0.6 mm signal layer)

• Sikaplan® WP 1100-20 HL (2.0 mm total nominal thickness, 0.6 mm signal layer)

• Sikaplan® WP 1100-21 HL2 (2.1 mm total nominal thickness, ≤ 0.2 mm signal layer)

• Sikaplan® WP 1100-22 HL2 (2.2 mm total nominal thickness, ≤ 0.2 mm signal layer)

• Sikaplan® WP 1100-25 HL2 (2.5 mm total nominal thickness, ≤ 0.2 mm signal layer)

• Sikaplan® WP 1100-30 HL (3.0 mm total nominal thickness, 0.6 mm signal layer)

• Sikaplan® WP 1100-31 HL2 (3.1 mm total nominal thickness, ≤ 0.2 mm signal layer)

• Sikaplan® WP 1100-32 HL2 (3.2 mm total nominal thickness, ≤ 0.2 mm signal layer)

Sikaplan® WP 1100-21 HL2 is used as the benchmark for this EPD.
