KDS is a I developed a waterproofing membrane with ultra-high viscosity. It uses high-strength polyethylene, polyester AL as a surface material as an intermediate layer to DUWICH patent glue, complemented by isolating material, done special treatment of the self-adhesive waterproofing membrane surface. Concrete with very good adhesion, fusion, and also good dimensional stability, superior healing properties and advantages.
Application
Basement
Underground buildings
Platform
Roofing
Step
Square floor / roof garden / terrace
Advantage
Superior bond strength, self-adhesive construction, safe and reliable. Avoid fire hazard instability and hot melt glued construction method. Extended performance, be able to withstand the primary general deformation, cracks and other negative phenomena. Strong grass-roots self-locking water performance may be due to membrane damage caused by leakage limits in the local area, to avoid the overall failure of the waterproof layer. The unique "self-healing" function, self-healing small puncture damage, automatically filling smaller base crack healing.
| Feature | Advantage |
|---|---|
| Waterproof | Adequately supported, resistance to hydrostatic pressure. |
| Multi-layer laminated | Provide a full range of stability, high tear strength, excellent resistance to penetration, impact resistance |
| Super adhesive, fusion | Strong bonding or fusion (cement, glass, AL, sediment), and a variety of base surface in order to ensure a very good protective properties |
| Monolayer | Paving convenient, reliable performance, with on-site construction plan, low labor costs. |
| Cold applied | Without heating, self-adhesive at the overlap to ensure continuity. |
| Resistance to chemical attack | Resistant to soil erosion, infiltration of groundwater, provide effective external protection. |
| Good flexibility | Can withstand minor settlement and shrinkage deformation. |
| Stable thickness | Factory-made products to ensure the continuity and stability of field applications. |
| System waterproof guarantee | The waterproofing membrane waterstops combination system waterproofing performance can be further enhanced. |
Construction
According to the engineering practice, the Shop can be used wet, dry shop, pre-Shop anti-stick, empty shops and a variety of construction methods.
Priority to the use in the construction of the wet-laid method of construction, the perfect combination with the base surface, strong bond, no channeling water may.
KDS is a high quality, state-of-the-art, cold applied preformed flexible waterproof material. It is penetrated by a special high-performance multi-layer high-strength anti-polyethylene film and patent laminated composite composite self-adhesive. This high-quality, state-of-the-art end of film through the multi-layer lamination and chemical bonding, so that all levels tightly bonded together have greatly improved physical properties than conventional low-density polyethylene. Tear strength, puncture resistance, impact resistance performance have been improved, thus also improve the ability to resist accidental damage. Junction inverted waterproof material and embedded in the concrete water stop at the same time, we can provide a continuous waterproof foundation and underground construction / concrete waterproofing layer system.Manufactured in a factory with manual brushing material, the thickness of the membrane is consistent factors from construction geographically dispersed, highly flexible, it can easily compensate for the shrinkage cracks in the concrete and can withstandtypes of slight deformation of the structure within the service life.
Installation
In the vertical plane, pavement KDS work needs to be suspended, should be set lath fixed waterproof membrane to prevent slipping. Continue with the work, you should remove the lath and re comprehensive laying a layer KDS.
When laying the KDS, peel off the protective paper behind the sticky side of the paving to the primer surface, The paving should brush the surface of the laminated film to ensure good initial adhesion can be squeezed to remove the air bubbles. Adjacent waterproof membrane should be aligned, alignment, side seams and at least 50 mm overlap, the compaction with KDS drum force, to ensure that the waterproof membrane between the fully bonded and continuous, broken parts should be clean, and waterproof membrane is larger than the damaged area to be repaired and compacted.
The backfill material should be compacted layer by layer, to prevent subsidence and drag passed to the waterproofing system.
