Two component, thixotropic, cementitious modified polymer waterproofing membrane.
Newton 103-S is a two component, thixotropic, cementitious modified polymer waterproofing membrane with high adhesion, designed for the internal and external waterproofing of concrete and steel elements of water-retaining and water-resisting structures such as reservoirs, water tanks, below ground structures, podium decks, and parking areas.
Capable of resisting extremely high positive and negative water pressure, it forms a hard, highly alkaline coating with a degree of elasticity which has greatly enhanced chemical resistance and so is particularly suited for the protection of concrete within sulfate contaminated ground. It has excellent resistance to the ingress of acid gases, moisture and chlorides to enhance the durability of reinforced concrete and protect highway and coastal structures from chloride attack.
It is recommended that Newton 103-S and its ancillary products be installed by contractors trained by Newton Waterproofing Systems in the correct use and specification of the product.
Surface preparation is required, as is protection after application - consult manufacturer for details.
Features and benefits:
Resistant to 10 bar positive or negative water pressure, quick application in one coat, providing a hard, durable and trafficable finish
2 mm thick waterproofing membrane
30 kg in two parts - 6.1 kg Part A (Liquid) and 23.9 Part B (Powder)
When specified, installed and protected in accordance with the Data Sheet and Application Guides, is fully and permanently isolated from UV light and physical damage or wearing, and only to those substrates confirmed within, Newton 103-S has a service life that can be equal to the design life of the structure
