일반적으로, 방수공법은 방수층을 구성하는 재료의 유형에 따라 시트방수와 도막방수로 나누어진다.Generally, waterproofing methods are divided into sheet waterproofing and film waterproofing depending on the type of material that makes up the waterproof layer.
상기 시트방수는 합성고무나 합성수지 또는 개량 아스팔트를 주원료로 제조된 방수시트를 겹쳐 붙여서 방수층을 형성하는 공법으로써, 합성고분자 시트방수와 개량 아스팔트 시트방수로 나누어진다.The sheet waterproofing is a method of forming a waterproofing layer by overlapping waterproofing sheets made from synthetic rubber, synthetic resin, or improved asphalt as the main raw material, and is divided into synthetic polymer sheet waterproofing and improved asphalt sheet waterproofing.
상기 도막방수는 합성수지 재료를 바탕에 일정두께 도포시켜 방수도막층을 형성하는 공법으로써, 액체 상태의 방수재를 그대로 도포하는 액체형 도막방수, 방수재를 휘발성 용제에 녹여 액체상태로 만든 다음 콘크리트 바탕에 바르는 용제형 도막방수, 우레탄수지를 도포하여 방수층을 형성하는 우레탄 도막방수가 있다.The above-mentioned film waterproofing is a method of forming a waterproof film layer by applying a synthetic resin material to a certain thickness on the base. Liquid-type film waterproofing is applied as a liquid waterproofing material, and the waterproofing material is dissolved in a volatile solvent to make it into a liquid state and then applied to the concrete base. There is a urethane film waterproofing that forms a waterproof layer by applying urethane resin.
또한, 시공방법 또는 방수목적에 따라, 바탕면에 도막 방수재를 일정두께 도포한 도막층을 형성한 후 상기 도막층 상에 방수시트를 시공하는 복합방수공법이 사용된다.In addition, depending on the construction method or waterproofing purpose, a composite waterproofing method is used in which a waterproofing material is applied to the base surface to form a coating layer of a certain thickness and then a waterproofing sheet is constructed on the coating layer.

There is a problem in that defects such as lifting or fracture occur in a shorter period of time.
이에, 습윤상태 또는/및 진동 또는 충격 등의 거동에 대한 대응성을 가짐에 따라 방수층의 사용연한을 유지 또는 증가시킬 수 있는 방수구조 또는 시공방법에 대한 개발의 필요성이 대두되고 있다.

As the molecular weight increases, toughness, plasticity, stress cracking resistance, and impact resistance improve, but formability and surface gloss decrease. In addition, as the vinyl acetate content increases, compatibility with polymers or plasticizers with different density, rubber elasticity, and flexibility improves, and the softening temperature decreases. In other words, it is flexible but not strong at low temperatures, but has high impact strength, good weather resistance, good tear strength, stress crack resistance, and ozone resistance. It is lightweight, transparent, and non-toxic compared to rubber, and has a large amount of vinyl acetate units. Flexibility increases, but melting point decreases, resulting in good adhesion.

It is made by copolymerizing acrylic monomers with OH, COOH, greenzyl or amino groups with acrylic acid ester, methacrylic acid ester, styrene, etc., and fillers are added. As a result, a strong formed product can be obtained and has the physical properties of transparency, weather resistance, and high hardness. In other words, EVA or acrylic resin improves the hardness and flexibility of asphalt and prevents it from breaking easily.
