Exploring the Underlying Constraints to the Use of Geosynthetics for Civil Engineering Infrastructure: A Study from Ghana

Abstract

Whereas the level of use of geosynthetics on continental basis is generally considered to be low, little is known of country-specific studies that unravel the constraints to the use of geosynthetics for civil engineering infrastructure in the construction industry. Thus, this study seeks to identify the underlying constraints to the use of geosynthetics for civil engineering infrastructure in Ghana and determine the relative significance of each of the underlying constraints on the use of geosynthetics for civil engineering infrastructure in Ghana. A mixed methodology was employed. A structured questionnaire and structured interview helped in data collection. Data were analysed using frequencies, percentages, mean, standard deviation, one sample t-test, and the Relative Significance Index (RSI). Nineteen (19) underlying constraints were identified as the constraints to the use of geosynthetics in Ghana. Each recorded a significant RSI value from 0.70 to 0.95 and t-test values were statistically significant. The lack of a geosynthetic research institute to champion research-driven campaigns for geosynthetics use in Ghana, and the use of geosynthetics is not prioritized in the manifestos of political parties in Ghana were unique constraints to this Ghana study only. In terms of civil and construction engineering practices, this study has offered an understanding of the constraints to the use of geosynthetics in Ghana and provided the theoretical basis for future geosynthetic-related studies.
