Basement Waterproofing Products
The basement is space below the outdoor ground in the buildings. Basement waterproofing project, like a mirror, reflects the quality and safety of buildings. Basement waterproof is an important project that not only to ensure the use of underground space but more importantly - to protect the building safety.

DWD 120 Waterproofing Membrane Brochure.pdf


DWD waterproofing membranes are a type of cement based polymer fabric waterproof material. The waterproof membrane can be used in combination with a special cement adhesive in the case of a cementitious substrate. The cement adhesive can easily enter the non-woven fabric of DWD waterproofing membranes and form a good, cured and permanent waterproofing layer.
DWD waterproofing membrane is a new type of waterproofing sheet which is added with additives, anti-aging layer, reinforced adhesion-promoting layer, and polypropylene non-woven fabric through the automatic production line. It can effectively solve the issues of water leakage and moisture seeping in the basement. Also, DWD waterproofing membranes are suitable for many different surfaces, especially in cement substrate basements. As well as its weldable feature for waterproofing membranes’ edges makes your basement waterproof works reliably.

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 agingRetention 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.


Parameters of cement adhesive should meet the standard of GB 50108-2008 Technical Specification For Waterproofing Of Underground Works as shown below.

ItemParameter/Result
Bond tensile strength (Mpa) with cement substrate surfaceNormal temperature in 7days≥0.6
Water resistance≥0.4
Freezing resistance≥0.4
Operating time (h)≥2
Permeability resistance (Mpa, 7d)≥1
Adhesion under shear condition (N/mm = normal temperature)Membrane to membrane≥2.0
Membrane to substrate≥1.8
Compression strength (Mpa)≥9
Flexibility (28d)compression strength/bending strength≤3

Note:
Normal temperature is defined +25℃.
The performances of compression strength and flexibility must meet the parameters as shown above when roofing waterproofing works.


Installation Guide
A complete waterproofing work should include the following steps:
The base or concrete cleaning and checking (leveling blanket) → Making cement adhesive → Special areas and joints waterproofing membranes laying → Waterproofing membranes laying → Seams sealing → Waterproofing works checking → protection layers installation (if needed) → Maintenance
Notes for roof waterproofing:
Before roof waterproofing, it is necessary to carefully check the roof construction drawings, master the details of the construction drawings and related technical requirements.
Seams of waterproofing membranes are a key point in roof waterproofing works. Make sure all the seams are well welded. If necessary, every junction of two waterproofing membranes should be more than 50mm for welding.
