Self-adhesive Asphalt Waterproof Membrane

1.Introduction 

Self-adhesive  Polymer Modified Bituminous Waterproofing Membrane is a patented product which  is independently developed by Guangzhou Dayu. This Self-adhesive Membrane product  is made of synthetic rubber and high quality asphalt.by added in active  chemicals and reinforce materials (PY type) or non-reinforced (N type). Use  peelable silicon PE/PET film as insulation film. It is a cold-applied  waterproofing membrane product. With its unique bonding mechanism.paved with  wet-applied or pre-applied method.DCPS self-adhesive membrane can supply a  gapless complete waterproof sealing system.it will construct a strong bonding  between waterproofing membrane.polymer cement and basement.so realized full and  permanent combination.forming a reliable “Skin Type” waterproofing  system.

3.Features
 1)  Strong puncture resistance.high tearing resistance.high ripping resistance.high  elongation.and excellent dimension stability and low temperature resistant  performance.
 2)  Perfect Self-Healing performance and strong creep property.it is very adaptive  to base deformation.and can meet the rigid waterproof performance of  concrete.to form flexible and rigid double waterproof effect. 
 3) No  need to apply primer and hot melting.no fire risk.and we don’t require  treating the uneven basement.so the construction is convenient.economical.safe  and environmentally friendly,

4.Application  scope
 1)  Various industrial and civil buildings.basement.roof.
 2)  Underground construction.railway tunnel.subway.bridge and highway project.
 3)  Swimming pool.fire pool.water ditch and pipe drain.
 4)  Sewage pool.refuse landfill.artificial lake and municipal works.

6.Constructions  - Pre-appled:
 

image004.jpg

 1)  remove dust.debris from the substrate surface.but no ponding left.
 2) All  joints (corners.construction joints.post-cast strips.deformation joints and  through-wall pipelines) should be reinforced first.
 3)  pave the membrane along the alignment and keep min. 60 mm overlap for joint  area.
 4)  peel off the cover on overlap area.use a hand-hold press roller to roll and  press the lapping area.exhaust air.and ensure a tight bonding.
 5)  peel off the isolating film of the membrane upper surface. pour cement mortar.
 6)  Advantages: it can achieve the “skin type” waterproofing performance.can prevent  watermoving between  layer.
 

7.Cautions
 1 Don’t install if  the temperature is lower than 0 ℃.the basement is polluted.there are water or ice on basement.
 2 Don’t install with  others construction processes at the same time.if need to install others  facilities on ready waterproof layer.take actions to protect the waterproof  layer from damage and the waterproof layer under facilities should be  reinforced.
 3 Don’t put any  material.machines or facilities on ready waterproof layer.and don’t touch the  waterproof layer with any sharp objects in order to prevent the waterproof  layer from damage.
   

8.Storage: 

 Different  items.models.dimensions and grades should be stored separately.
 Store  the products in a dry and ventilated place with the storage temperature less  than 50℃.and products should be placed upright and stacked no more than two  layers.
 Keep  products in an upright position during transportation..avoid incline and cross  squeeze between rolls.
 The  shelf-life is one year under normal storage condition.not be more than one  year.
