In this technique the grout is injected into the ground without disturbing the soil structure. In this investigation an attempt is made to study the comparison of permeation grouting with cement and lime grout. The cement grout and lime grout are injected into the soil specimen by changing weight of cement and lime which will be at 2%, 4%, 6%, 8%, & 10% by the soil weight. Grouting is conducted in a tank of size 30 x 30 x 30cm. The grouted samples are tested in triaxial test after 1, 7, & 14 days of curing period. The permeability test also conducted on the grouted samples. The test results revealed that the shear strength properties are improved for grouted soil, where as the permeability is reduced.

INTRODUCTION Soil improvement is an important project in construction works, especially in those for buildings, bridges, and roads, etc. In practice, many methods are used to improve in-situ properties of deep soil layers, such as dynamic compaction, stone columns, jet grouting, compaction grouting, vibroflotation and wick-drains. However, these methods are generally expensive as they involve accumulation of huge machinery and equipment. The permeation
