1. Removal of slided material on the road side. 2. Construction of toe support retaining wall with sufficient weep holes and hill side drain.
1. Toe cutting of slope during road construction and road widening, 2. Pore water pressure developed in slope forming material during heavy rainfall reduces its shearing strength and thereby leading to slope failure.
