PART 1 JOB DESCRIPTION
Soil Stabilization Method a. Soil Stabilization is preservation of one or more soil properties to improve the engineering characteristics and performance of a soil. Chemical soil stabilization is by blending and mixing suitable chemical admixtures or stabilizing agents with insitu soils to improve and strengthen the certain properties through chemical reactions for engineering purposes. Purpose of soil stabilization Reduction of plasticity index (PI), swelling potential for clayey soil Increase in durability and strength Improved the strength and stiffness of the soil layer Effectively utilize of locally available soils and other materials as road construction material.
PART 2 METHOD STATEMENT
2.1 General Soil Improvement and subgrade stabilization. Wet, weak, fine grain soil can prove to be a major challenge at many construction sites. Muddy site conditions make for difficult working conditions. Access is difficult for construction vehicles. Wet, poorly compacted soil makes for poor pavement support and embankment/fill. Construction sites often proceeds under time constraints. The use of chemical soil stabilization to dry and modify marginal and poor soils can assist in keeping projects on schedule during wet weather by providing a working table that sheds water and allows return to work more quickly after rain events. Soil Stabilization quickly improves the soil condition during construction and can add long term improvements to key soil properties. Adding TerraFirma Soil Stabilizer can cause three major soil improvements: Soil Drying Reducing the soil moisture content Soil Modification Reducing soil plasticity, aiding compaction and increasing early strength Soil Stabilization Increasing long term strength and reducing swell potential
2.2 Broad ranges of application Airports Parking lots Mining roads warehouses Agricultural roads Rural road Subdivision road Plantation road

PART 4 TERRAFIRMA SOIL STABILIZER
4.1 TerraFirma Soil Stabilizer Polymer modified cementitious chemical agent in fine powder form Designed for soil stabilization especially for sandy and clayey soils under tropical condition and environment
4.2 Benefits Less permeable layer Stabilized soil permeability decreases and therefore minimizes mechanical loosening caused by water penetration. As a result stabilized soil provides much longer durability when compared to those of un-stabilized materials. Stabilized layer Unsealed/unstabilized roads on the other hand, easily lose their structural integrity in the presence of water, and load. Layers, and layers of gravel may be added and compacted but, since the surface is unbound, these deteriorate easily in the presence of water, and heavy loads. As such, a never ending cycle of road maintenance is needed. Unbound/ unstabilized materials
4.3 Savings Saves Money - Generally, there is no need for aggregates (and associated hauling). Saves Time - Stabilization is very fast, 3-4 days/km. Also, time associated with base preparation (hauling of aggregates) is eliminated. Saves Environmental Impact - Imagine removing 50 truck loads of soil and bringing in 50 truck loads of imported material/aggregates. Less costs, less congestion, less carbon footprint.
