Descripción
SikaTop-209 ES is a two-component, pre-dosed, flexible waterproofing mortar based on cement, selected aggregates and modified polymers.
ADVANTAGES
- Low modulus of elasticity, which achieves good flexibility, reduces the risk of cracking and improves the ability to bridge shrinkage cracks and microcracks.
- Impermeable to water and permeable to water vapor
- Suitable for both positive and negative pressure
- Predosed
- Excellent adhesion on healthy supports of concrete, mortar, stone, brick, etc.
- High resistance to ice and deicing salts
- Slows the progression of carbonation
- Good crack pointer properties
- Suitable for contact with drinking water
APPLICATIONS
It can be used to make waterproofing and protective coatings on surfaces in which flexibility is required, in order to spot small cracks. Some of the most common places where it can be used are:
- Tanks, pools, canals or other elements intended to contain water, whether buried or not buried.
- Interior basement waterproofing
- Exterior waterproofing of buried walls
- Repair and protection of surfaces exposed to the action of ice and deicing salts: bridge parapets, terrace and roof overhangs, cornices, etc.
- Protection of concrete structures in marine environments
- Waterproofing in contact with drinking water
CHARACTERISTICS
- Chemical base: Cementitious mortar improved with synthetic resins
- Conservation: 12 months from the date of manufacture, in their original, well-closed and undamaged containers in a dry and cool place.
