Objectives of the
Study
The main objective of this study is to improve the methodology used in the previous study entitled
“Modification of Sansevieria Trifasciata (Espada) Fiber as Geonet'' for soil stabilization and erosion
control, and observe the differences based on the results.
Objectives of the
Study
1. To classify the type of soil on the site.
2. To assess the soil holding capacity of the enhanced geonet based on the eroded soil.
3. To determine the properties of the enhanced geonet whether it would pass the Standard
Specifications of Geonets for slope protection.
Objectives of the
Study
4. To determine the quantity of water that would pass through the geonet using further testing
techniques such as the water permittivity test.
5. To assess the efficacy of the geonet by contrasting the percentage of eroded soil on the protected
and unprotected slopes.
6. To compare the result of the study to the previous study (Modification of Sansevieria Trifasciata
“Espada” Fiber as Geonet) based on tensile strength, thickness, mass per unit area

Delimitation
It delimits that the study must be conducted on similar soil
surfaces with an evident slope that shows signs of erosion,
and is free from vegetations that may alter the results of
the study.

research is to examine
This study discusses measures for
retaining and strengthening slopes
using geogrids. Based on this study,
geogrids are used as a substitute for
natural armoring materials and are
able to solve increasingly complex
geotechnical issues. One of the
reasons we use geogrids is for the
anti-erosion protection of unstable
soils on natural or artificial slopes. This
study was able to identify the key
benefits of using geogrids, such as a
significant reduction in total costs
compared to traditional methods and
a significant reduction in the
thickness of the granular material
