Journal of The Institution of Engineers (India): Series A, 2019
The paper presents the effect of untreated and chemically treated coir geotextiles on the interface properties of sand–/clay–coir geotextile interface. For this purpose, two woven and two non-woven coir geotextiles were used. The chemicals used for the treatment of coir geotextiles were p-aminophenol, sodium periodate and sodium hydroxide.

Model Tests on Coir Geotextile-Encased Stone Columns with Tyre Crumb-Infilled Basal Coir Geocell
International Journal of Geosynthetics and Ground Engineering, 2021An encased stone column with a geocell mattress can serve as a flexible pile raft system, helping in the uniform transfer of embankment load to the underlying foundation soil, improving their behavior. The efficiency of encasement and geocell depends on various factors, among which the material stiffness is an important one. The present study addresses

Use of coir geotextiles in unpaved road construction
Geosynthetics International, 2010ABSTRACT: This paper reports the beneficial effect of five varieties of coir product inclusion (three types of woven coir geotextile and two types of hand-knotted coir netting) on the California bearing ratio (CBR) behaviour of four soils: a natural soft clay; a commercially available soft clay; lateritic soil; and sand over soft clay subgrade.

Numerical Studies on Coir Geotextile Reinforced Flexible Pavement
2020Geotextiles are permeable fabrics that can separate, filter, strengthen and drain when used in association with the soil. Natural geotextiles are more advantageous than artificial geotextiles because of its cost and environmental concern. Coir geotextiles have a life of 3 to 5 years depending on the type of coir geotextile.

Model studies on woven coir geotextile-reinforced sand bed
Proceedings of the Institution of Civil Engineers - Ground Improvement, 2011This note pertains to an experimental study made on model square footings underlain by woven coir geotextile-reinforced sand. About three-fold improvement in strength was obtained with the use of even a single layer of reinforcement, which suggests that woven coir geotextile is an appropriate material for subsoil improvement.

Surface Heave Behaviour of Coir Geotextile Reinforced Sand Beds
Journal of The Institution of Engineers (India): Series A, 2017Soil reinforcement by natural fibers is one of the cheapest and attractive ground improvement techniques. Coir is the most abundant natural fiber available in India and due to its high lignin content; it has a larger life span than other natural fibers.

Numerical Simulation of Coir Geotextile Reinforced Soil Under Cyclic Loading
2021Coir geotextile is a natural fiber derived from the husk of coconut, and its use as a reinforcement element has recently shown great potential for applications in geostructures. The biodegradable nature of the coir fibers makes coir geotextiles an environmentally friendly ground improvement alternative for use in various infrastructure projects. In the
