KTTL Geotextile is permeable to water but prevents the mixing of aggregate and soil when laid as a separator between the sub soil and aggregates. It also enhances the strength, durability, and structural integrity of the structure.
Non-woven KTTL Geotextiles are designed to restrict movement of different road layers and prevent reflective cracking. These attributes together with separation, filtration, protection, and reinforcement functions make KTTL Geotextiles, a preferred choice for road construction and repair.
The high tensile strength of KTTL Geotextiles, combined with its property of elongation, makes it the best material to increase the load bearing capacity of weak soils. Hence most ideal to be used in road construction, slope protection etc.
Minute perforations in the KTTL Geotextiles are designed to facilitate water flow & restricting the minute soil particles. As a result, the water pressure is reduced and load-bearing capacity of the structure is enhanced.
KTTL Geotextiles, due to high puncture resistance, prevent pumping of aggregates into the soil. This results in a stable soil structure.
KTTL Geotextile is designed to drain off excess water in soil, over the lateral plane of fabric resulting in higher CBR of soil
Application of geotextiles are varied and yet, unique. Geofabrics need to perform different functions based on different requirements. Broadly, the selection of the right geofabric is based on the functional need of the end application. Following points are taken into consideration:
1. Identifying the need and the primary function for which the geotextile is being incorporated in the design
2. Ascertaining the geotextile functions that govern this application 3. Establishing the property requirement based on site specific conditions
Geotextile, graded and selected through such a selection process, will not only serve the design intent but also set clear standards for the project implementation team.

Climate Change is a phenomenon that has gone from being widely debated to globally accepted within a span of one lifetime. Governments and corporates are mulling ways to reduce Greenhouse Gas (GHG) emission, so that the impact of climate change can be lessened, if not reversed. The use of KTTL Geotextiles in civil projects can provide sustainability benefits such as reduction in associated congestions, noise, air pollution and significant reduction in CO emission.
