Tunnel Waterproofing Membrane For Tunnel Waterproofing Projects Application

DWD WATERPROOFING offers efficient solutions for tunnel waterproofing projects such as expressway tunnels, subway tunnels, and mine tunnels, etc. The tunnel waterproofing system is a huge challenge due to its unique design requirements. In most of tunnel waterproofing projects, the waterproofing membranes are required to withstand certain mechanical impacts without damage. And also, the waterproofing membranes should have the features of corrosion resistance, durability, economy, etc., in order to ensure the reliability and safety of the waterproof projects.

Standards And The Main Performance
The performance of DWD 120 waterproofing membranes meets the standard of GB 18173.1-2006 High Polymer Waterproofing Materials as shown below.

ItemParameter/Result
Breaking tensile strength (N/cm)Normal temperature≥60
60℃≥30
Elongation at break rate (%)Normal temperature≥400
-20℃≥10
Tear strength (N)≥20
No leakage performance (0.3Mpa, 30min)No leakage
Bending temperature under low temperature (℃)≤-20
Heating expansion amount (mm)Extension≤2
Contraction≤4
Hot air aging (80 C x 168h)Retention rate of tensile strength (%)≥80
Breaking tensile strength retention rate (%)≥70
Alkali resistance (mass fraction of 10% Ca (OH) 2 solution at normal temperature x 168h)Retention rate of tensile strength (%)≥80
Breaking tensile strength retention rate (%)≥80


Artificial climate aging

Retention rate of tensile strength (%)≥80
Breaking tensile strength retention rate (%)≥70
Bond peel strengthStandard test condition (N/mm)≥1.5
Soaking retention rate (%)Normal temperature x 168h70
composite strength (surface and core layer) (N/mm)≥1.2

Note:
Normal temperature is defined +25℃.
The performances of artificial climate aging, heating expansion amount, breaking tensile strength at 60℃should not consider if waterproofing membranes are non-exposed.
For the total thickness is less than 1.0mm of the resin composite waterproofing membranes, its elongation at break rate should not be less than 50%, and other performances can reach more than 80% of the prescribed value.
