Underground Parking Garage Waterproofing Membrane For External Wall Application


In the underground garage waterproofing system, it is generally necessary to add a waterproofing layer on the external wall, because the concrete itself can meet the waterproof requirements, but there will be structural joints during construction, which can not meet the requirements of waterproofing. So generally, a layer of waterproofing membrane should be added to the outer wall to ensure the waterproofness of the underground parking garage waterproofing system. DWD waterproofing membranes can offer a premium waterproofing performance in underground parking garage waterproof system.

Features of DWD waterproofing membranes
Excellent waterproofing and anti-seepage ability.
Good tensile strength, adaptability to deformation and flexibility at low temperature to meet wide temperature range application.
Soft texture, good adhesion, can be installed in no obvious water condition and firmly bonded.
Long service life, chemical corrosion resistance, aging resistance, non-toxic.

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.

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.


Package and Storage
Each roll of DWD waterproofing membranes is packed by a woven bag and plastic plugs in both ends. Beyond that, we are surely available to provide your customized service including design, brands, color, etc.
For storage, It is advisable to store the waterproofing membrane rolls in a dry place, sheltered from the sun in the summertime, because of the greenhouse effect. And It should also keep the waterproofing membrane rolls in the temperature range of -38℃ to +40℃. Different categories and specifications should be classified and should not be inclined or cross-stressed. And always keep the waterproofing membranes away from a fire.
