NTI is a privately-owned Canadian Company based in Vancouver, British-Columbia
NTI specializes in Nanotechnology based Soil Stabilization
NTI’s Team of Experts has extensive experience in applying its Nanotechnology at world-wide
Introducing:
Iron nanoparticles (nanoFE) react with the natural colloids of the cement
(portlandites and tobermorites), generating a hard and resistant matrix,
concentrations of cement vary from(2.5 to 6%) depending on the
requirements
Polymer chains on the surface of the nanoFe particles provide a self-
binding capacity by increasing the dynamic support force
This process reduces the specific surface area of soils due to the
agglomeration and setting effect of the fine particles, which will be
coated with submicronic water-repellent particles supplied by the
polymer
This effect occurs both at depth and in the surface layers, resulting in
greater structural impermeability and positively influencing sensitivity to
water, the main problem in the maintenance and stabilization of any type
of soil with a high content of active fine particles
Soil Stabilization Process
Applications:
-Road Construction for Major Highway Soil Stabilization, sub base for
asphalt or concrete wearing coat.
-Road Construction as driving surface for secondary, agriculture and
mining roads.
-Road Shoulder Stabilization utilizing purpose constructed soil mixer
-Deep Soil Mixing – Foundations.
-Surface Water control at Agriculture and Industrial Facilities.
-Dam Stabilization
Benefits:
-Offers a highly cost-effective solution by using in-situ soil (incl.
recycled asphalt & concrete roads), no additional aggregate required.
-Reduces Construction Time.
-Reduces Environmental Project Footprint
-Increased Compressive Strength
-Increased Bending Strength
-Increased Impermeability

Performance
Compressive strength (Type HBR A.6 (9) soil)
Swelling: Swelling characteristics on Type HBR A.7-5 (16) soil (AASHTO
Soil Classification System - from AASHTO M 145 or ASTM D3282) were
assessed comparing natural soil (3.65% swelling), to soil + lime (1.25%
swelling) and soil + lime + NANO SOILTEK ES (0.8% swelling).
Performance Test for Deep Soil Mixing
Compressive strength on clayey soil
Kaolinite – IP55, WL = 55%, 45% initial moisture
NANO SOILTEK ES with cement introduced as a grout containing water,
bentonite, cement and NANO SOILTEK ES
Approximately 20% increase in strength after 28 days at 0.5% NANO
SOILTEK ES (by weight of cement)
Application rates
Road Construction & Soil Stabilization
Methodology
Application
Application of diluted NANO SOILTEK ES using mechanical Wirtgen Mixer
connected to water truck mixing into cement & in-situ soil.
Application
Sealing of NANO SOILTEK ES if requested, applying asphalt wearing coat
not sealed
NANO SOILTEK ES can be used without sealant for secondary roads, agriculture and mining roads, runways etc.
