Basic Waterproofing Materials

Asphalt
Asphalt is a dark brown or black which is binding on solid or semi-solid material, its major component is obtained by distillation of crude oil or natural bitumen.
Since the 16th century the natural asphalt was found and used for a while.
The end of 19th century, peoples get to know that they can get to the asphalt of similar natural characteristics from the distillation of crude oil and this product was called petroleum products.
According to the rapid progress in this recipe occupies most of the current usage of asphalt.

The natural asphalt is include soil, but petroleum bitumen is the only asphalt and the chemical composition of asphalt is a hydrocarbon.
Mainly consists of three mixed by aliphatic hydrocarbons, naphthenic tenjok hydrocarbon, an aromatic hydrocarbon.

Petroleum asphalt is according to the classification of the solubility of the solvent carboids and carbenes are extremely low consists mainly maltenes and asphaltenes.
This is important data for determining the properties of asphalt, these ratios.
Generally, softening point's adhesive strength and stretch are grow but the strength and stability is become a weaken.

In the construction field, devide on purpose of use for asphalt is waterproofing and asphalt paving.
The waterproof asphalt is keeping with the mainstream of the waterproofing method, and used as a raw material for roofing and asphalt melted material (roofing adhesive) the waterproof asphalt.
In the past, A mixture of asphalt and stone dust, sand and crushed stone Have been used for the mastic material and the floor of the hot water, Early in the modernization of country In Korea, the case of construction used of mastic asphalt emulsion but now do not use very little.

Asphalt concrete is used to the paving of road construction by mix the filler such as stone, sand, crushed stone.
The advantage of the asphalt paving is get a quick installation, proper elasticity, easy maintenance.
The kinds of pavement are asphalt concrete pavement, semi-rigid packaging (半 剛性 鋪裝), permeable packaging (透水性 鋪裝), asphalt emulsion packaging (乳劑 鋪裝), asphalt emulsion by simple packaging (簡易 鋪裝) and others.
Waterproof Asphalt Materials

Straight Asphalt

Straight asphalt is the bituminous material remaining soft minutes classification to through the atmospheric vacuum distillation unit such as crude oil.
Blowing Steam is for remove to the remaining soft oil.
Straight asphalt of less than 40 penetration degrees is mainly used for the industrial, if over the 40 penetration degrees mainly used for road paving and repair structures.

Blown Asphalt

Blown asphalt is used for water-proofing and electrical insulation and etc, air oxidation polymerization by heating and blowing into the straight asphalt, Blown asphalt is become a oxidative polymerization (酸化 重合) by heating and blowing air into the straight asphalt, It is uses for electrical insulation and waterproof.

Waterproof Asphalt

Gilyoung waterproofing asphalt is improved the necessary performance of asphalt.
It is compound asphalt mainly use the waterproofing construction of reinforced concrete structures, steel structures, and structure is equivalent similar to other structures. (Quality of Waterproof asphalt)

Modified Asphalt

Gilyoung Modified Asphalt is petroleum and synthetic rubber blended to the asphalt improving the viscoelastic properties of asphalt or as thermochromic.
The rubberized asphalt blended asphalt with rubber and generally used for road pavement or construction of road joint.
The improved asphalt of blended polymer with asphalt is used for waterproofing construction.

Waterproofing Materials

Modified Asphalt Sheet Waterproofing Materials

Gilyoung has improved the Modified Asphalt Sheet Waterproofing Material.
Resin (APP: Atactic Polypropylene) and synthetic rubber (SBS: Styrene Butadiene Styrene), etc.
In place of waterproofing roof conventional method of the hot asphalt and developed the non-woven synthetic fiber reinforced waterproofing sheet to improved polymer asphalt.
Recently, method of waterproofing construction is adhesive the bottom surface with the heating the back of sheet by the propane torch.

Early in the year of 1990, the torch method was begun to by the imported from the United States, Europe, Japan.
It was adopted as the standard construction method for building construction specifications in 1994.

Improved polymer asphalt
Gilyoung Modified Asphalt is petroleum and synthetic rubber blended to the asphalt improving the viscoelastic properties of asphalt or as thermochromic.

The improved asphalt of blended polymer with asphalt is used for waterproofing construction.

- Rubber: Thermoplastic rubber (SBS, SIS), styrene-butadiene rubber (SBR), butadiene rubber (BR), butyl rubber (IIR)
- A synthetic resin-based: polypropylene (PP), polyethylene (PE), ethylene-vinyl acetate (EVA), ethylene ethyl ah create (EEA)

Synthetic polymer waterproof sheet material

Recently a crack in a concrete slab constituting the building generation are accepted as unavoidable circumstances. Also show the iteration of the elastic behavior of the joints based in the sheet materials. Accordingly this sheet waterproofing is basically made by synthetic rubber and a synthetic resin resistant the followability based on the material, and evaluated as a good conformability and adaptability .

Gilyoung synthetic polymer sheet waterproofing material is produced in sheet form from the factory, it is appropriately managed by dimensions (thickness, width, length) of the good quality material.
Furthermore have sufficient weather resistance and durability (music light, ozone, etc.), water resistance, heat resistance, and have the effect of temperature changes less material. This is suitable for waterproof course of expose roof because a waterproofing material color range is various.
