Earth Material Sealants
KF-D
EMS for dust control and soil stabilization, waterproofing agent
Light gray powder with specific smell. After application, the smell disappears.
This inorganic compound works as an admixture to the cement containing Earth-Materials-Sealants (EMS).
Benefits
- Initial solubility of KF-D with water is 100%.
- Final hardened product is insoluble even in acid or salt water.
- Completely reduces bubbling of the standard mixture.
- Hardening time is adjustable.
- KF-D does not affect the environment.
- The application of KF-D using injection or sorption treatment creates a chemically altered structure with increased density and reduced hydraulic conductivity.
Uses Of KF-D
- Improves density and impermeability of soil or severely deteriorated structures. KF-D added to standard EMS mixes can be used for injections under or into sinkholes, foundations, tunnels, dams, wet and polluted soils, etc.
- Strengthens the standard EMS formula and increases waterproofing.
- Improves binding with standard concrete fillers and particles of soil.
- Applicable as a dust controlling premix.
Application
Add 5.5 Lbs of KF-D per 200 Lbs of cement or 2.5 Kg of KF-D per 100 Kg of cement to EMS and mix for 10 min.
Add pure water to produce a water to cement ratio of 0.38.
Mix for 5 minutes and unload into the hopper of pump station.
Apply mix through injectors into the targeted damaged areas.
The KF-D and EMS premix can be poured onto soils with or without subsequently mixing with the soil for stabilization and waterproofing of soaked areas.
