Parking lot waterproofing system can be divided into parking garage waterproofing system and parking deck waterproofing system. DWD WATERPROOFING has committed to parking lot waterproofing membranes for many years. DWD waterproofing membranes can meet different construction conditions and waterproof requirements according to the building structure of the parking lot.

Parking garage waterproofing system

Parking garage waterproofing is an important indicator to measure the quality of building engineering. The quality of parking garage waterproofing works not only affects the performance of buildings, but also the safety of buildings. Most of the parking garage is a reinforced concrete structure, which is an excellent and easy to install substrate for DWD waterproofing membranes.

DWD waterproofing membrane is a waterproofing membrane with a cement-based base that can be perfectly bonded to the cement base layer to achieve waterproof and moisture-proof purposes. Besides of parking garage waterproofing system, it also can be performed in parking deck waterproofing system.


Parking deck waterproofing system

The roof parking lot roof is a kind of special roof. There is much more dynamic load, impact load and vibration than ordinary roofing. And its waterproof is uniquely challenging. DWD waterproofing membranes can protect cars withstand damaging emissions as above. And also it can endure cyclic weathering and mechanical damages. DWD waterproofing membranes have a perfect solution to meets those performances.


Introduction of DWD waterproofing membranes

The upper and lower surfaces of the DWD waterproofing membranes are rough, and its non-woven fabric has a random cross structure to form a three-dimensional mesh, which has high tensile strength, strong impermeability, good low-temperature flexibility, small expansion coefficient, and temperature rise effect. It has strong adaptability, a large friction coefficient can be used with a variety of adhesives, and has a good bonding effect.

Cement paste can be used to bond a DWD waterproof membrane with the cement substrate surface. Cement paste can directly enter the mesh of the membrane surface. With cement solidification, cement paste does not exist aging, mildew, hydrolysis and other problems, so the bonding is permanent and firm.

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 Of DWD Waterproofing Membranes
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

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.
