In MULTISEAL concrete, thermosetting resins are used as the principal polymer component due to their high thermal stability and resistance to a wide variety of chemicals. MultiSeal can include aggregates that include silica, quartz, granite, limestone, and other high quality materials.
In simplistic terms, MultiSeal is a polymer emulsion, which includes polymer, geofabrics, cement and selects silica. The combination of these elements results in a high-tech waterproof liner with superb flexible strength. MultiSeal is designed to be highly acid & alkaline resilient.
MultiSeal Ultraviolet Protection is Three Fold
- MultiSeal Geoliners are designed to provide protection from the harsh environment of outdoor weathering, especially the deterioration caused by UV radiation. One of the main influences on the polymer coatings performance is the amount and type of UV absorbers used in the coatings. Zinc Oxide (ZnO) nanoparticles provide long term protection from harmful UV radiation in harsh environments. Zinc Oxide is an inorganic absorber it does not degrade over time like organic UV absorbers.
- Cementitious Additive – virtually unaffected by heat and UV.
- Plaster Sand (siliceous sands) – is added to MultiSeal to deflect UV radiation.
MultiSeal are applied in three layers. Layer one bond to the geotextile or base surface and once dried, a second layer of MultiSeal mix is applied. Once dried a third layer of MultiSeal mix is applied. Each layer of MultiSeal mix protects the previous layer.
As each layer consists of MultiSeal (UV absorbing polymer), Cement and Silica UV reflectors.
MultiSeal Geoliners – Backing Material
Earthen dams are lined with a geotextile prior to being sprayed with MultiSeal. For the building/construction industry no geotextile is needed unless there are gaps of 2mm and more.
