    Weldable House Waterproofing Membrane , Concrete Waterproofing Products Non Woven

    Weldable House Waterproofing Membranes And House Waterproofing Coating
    House waterproof project is divided into the roof waterproofing, the interior of the wall or the concave corner waterproofing, the pool waterproofing, basement waterproofing, garage waterproofing, etc. The choice of waterproof materials often affects the quality and progress of waterproofing projects.

    DWD House waterproofing products

    DWD polyethylene waterproofing membranes are a type of cement based polymer fabric waterproof material.
    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 problem of waterproof and moisture 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 house waterproof works reliably.

    Specification of DWD waterproofing membranes please see the sheet below.

    Thickness (mm)Length (m)Width (mm)Area (m2/roll)


    Note: Width can be customized such as 1500mm, 2000mm, 3000mm and 6000mm, etc.

    Parameters and Standard
    The parameters of DWD waterproofing membranes meet the standard of GB 18173.1-2006 High Polymer Waterproofing Materials as shown below.

    Breaking tensile strength (N/cm)Normal temperature≥60
    Elongation at break rate (%)Normal temperature≥400
    Tear strength (N)≥20
    No leakage performance (0.3Mpa, 30min)No leakage
    Bending temperature under low temperature (℃)≤-20
    Heating expansion amount (mm)Extension≤2
    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

    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.

    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

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

    DWD waterproofing coating can be used not only as an adhesive for waterproofing membranes but also as an exterior wall of a house. The coating is a kind of cement adhesive can easily enter the non-woven fabric of DWD waterproofing membranes and form a good, cured and permanent waterproofing layer. Moreover, itself can also paint on the cement substrate form a waterproofing layer for which the walls and the concave corners especially.

    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 and related technical requirements.
    Seams of waterproofing membranes are a key point in roof waterproofing works. Make sure all the seams are well welded. Every overlap of two waterproofing membranes should be more than 50mm for welding.
