Description

DYCSelf-adhesive Polymer Modified Bitumen Waterproofing Membrane
 
1. Product Overview
DYCSelf-adhesive Polymer Modified Bitumen Waterproofing Membrane isa patented product which is independently developed byGuangzhou 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 orpre-applied method,DYC self-adhesive membrane can supplya gapless complete waterproof sealing system, it will construct a strong bonding between waterproofing membrane, polymer cement andbasement,so realized fullandpermanentcombination,forming a reliable Skin Type waterproofing system.

3. Product 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 dont 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. Construction guideline
6.1 Wet Application:
substrate treatment →apply cement (mortar)→reinforce substrate joints→apply self-adhesive membrane→press down membrane and exhaust trapped air→seal the edge of joint→acceptance check.
 
6.1.1 substrate treatment: remove dust, debris from the substrate surface, dry surface should be wetted out first, but no ponding left. These sharp corners should be treated by mortar first with min. *0 mm radius for internal and min. *0 mm radius for external corner.
6.1.2 Scrape a thin layer of cement (mortar) over the substrate surface, mortar layer shall be wider than membrane by **0~**0mm.
6.1.3 All joints (corners, construction joints, post-cast strips, deformation joints and through-wall pipelines) should be reinforced first.
6.1.4 Peel off isolating film of the membrane lower surface, pave the membrane onto mortar layer along the alignment, and keep min. *0 mm overlap for joint area.
6.1.5 Press it down, exhaust any trapped air, and make sure membrane and mortar having a tight contact for the entire area.
6.1.6 Use a hand-hold press roller to roll and press the lapping area, exhaust air, and ensure a tight bonding.
6.1.7acceptable check.
6.1.8Advantages: the construction of the base surface can be damp, suitable to apply in rainy reasons
 
6.2 Pre-applied method:
substrate treatment →  reinforce substrate joints→apply self-adhesive membrane→seal the edge of joint→acceptance check→pour cement
6.2.1 remove dust, debris from the substrate surface, but no ponding left.
6.2.2 All joints (corners, construction joints, post-cast strips, deformation joints and through-wall pipelines) should be reinforced first.
6.2.3 pave the membrane along the alignment and keep min. *0 mm overlap for joint area.
6.2.4 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.
6.2.5 acceptable check.
6.2.5 peel off the isolating film of the membrane upper surface,  pour cement mortar.
6.2.6Advantages: it can achieve theskin type waterproofing performance, can prevent  watermoving between layer.
 
7.Storage
1) Different items, models, dimensions and grades should be stored separately.
2. Store the products in a dry and ventilated place with the storage temperature less than *0℃, and products should be placed upright and stacked no more than two layers.
3) Keep products in an upright position during transportation., avoid incline and cross squeeze between rolls.
4) The shelf-life is one year under normal storage condition.
 
8. Cautions:
8.1 Dont install if the temperature is lower than 0℃, the basement is polluted, there are water or ice on basement.
8.2 Dont 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.
8.3 Dont put any material, machines or facilities on ready waterproof layer, and dont touch the waterproof layer with any sharp objects in order to prevent the waterproof layer from damage.
