Application of EVA waterproofing membrane

Bitumen, also known as asphalt, is a sticky, black and highly viscous liquid or semi-solid form of petroleum. Thanks to its waterproofing qualities, it is widely used in construction. Bituminous Waterproof Membrane are perfect for waterproofing roofs, basements, below-ground structures, bridges and other structures.

Product Characteristics

1. EVA waterproofing membrane has outstanding softness, construction operability, and good waterproofing effect due to its tensile strength, tear strength, and small relative density.

①Good organic chemical reliability, corrosion resistance to strong acids and alkalis and salt solutions, and good insulation characteristics.

②Good flexibility, ductility and light transmittance, easy for the actual operation of engineering construction.

③High quality impact resistance, high tensile strength and good anti-aging properties.

④High quality barrier characteristics to gas and environmental humidity, and is a relatively highly impermeable raw material.

2. ECB waterproof board tensile strength, elongation, good puncture resistance, in a complex environment with vibration, distortion can also achieve a good waterproofing effect.

3. PE waterproof board has good toughness and good chemical resistance, anti-aging properties, not easy to corrode, and long service life.Contact us for more news.

Cautions

① Rain and snow, more than five winds, below 0 ℃ is not suitable for construction.
② Pay attention to ventilation when storing and transporting, avoid direct sunlight, and forbid direct contact with acid, alkali, oil, and chemical solvents.
Place in a cool and dry place, a suitable temperature below 15℃~35℃. The storage period is 12 months.

 

Construction method

① Clean up the oil, floating slurry, cement slag, loose layer, etc. On the base surface, deal with the unevenness and repair.
② Construction by hot air welding method.
③ Protection: the waterproof layer should be protected after the construction is finished to prevent punctures and other perceived damage.

 

Application

1.EVA waterproofing membrane is widely used in the waterproofing of tunnels, subways, human defense, and other projects.
2.ECB waterproof board is widely used in waterproofing tunnels, subways, and other projects.
3.PE waterproof sheet is widely used in anti-pollution, anti-leakage, anti-corrosion, and anti-toxic projects in tunnels and various industries.

 

 

Types Of Bitumen Membrane Waterproofing System

 

1.Self-Adhesive Bituminous Membranes

The main advantages of self-adhesive Bituminous membranes include: you don't need a torch or special equipment, making them perfect food wooden, small, flammable areas.

 

2.Polymer-Modified Bitumen Membrane

The polymer-modified bitumen membrane is the most popular choice for adding a waterproofing layer to a surface. This product provides additional flow resistance, which allows it to be used in scorching climates. They present as roll-fed sheet membranes and can withstand temperature fluctuations making them reliable and effective. 

 

 3.Polypropylene Membrane

This product comes in roll form and is also manufactured from the waterproofing material called bitumen. It is highly efficient and durable and most commonly used on concrete flat roofs. Other common areas of use are concrete gutters, retaining walls and basements.
