What factors should engineers and builders consider when selecting the appropriate geosynthetic material for a specific application?

Various factors need to be considered by engineers and builders when a geosynthetic material is selected, the primary one being the function of the material. Geosynthetics serve various purposes, including reinforcement, separation, filtration, etc. Understanding the required function will help narrow down the options. The site’s conditions, such as the soil conditions, climate, groundwater level, slope stability, etc., also influence the decision to pick the material. The material properties, like its strength, puncture resistance, UV resistance, and durability, as well as the installation considerations of the machine itself, are major requirements to be reviewed, as the availability of skilled labour, time constraints, etc., would vary the type of material.

Moreover, considerations of the long-term performance of the material and a cost analysis of the materials should be made. The cost considerations include the purchase, instalment, and maintenance across its lifespan. The material should also comply with environmental and regulatory rules, meeting industry standards, codes, etc. In the end, the manufacturer’s expertise and reputation regarding the material should be one of the major determining factors when purchasing the material. The manufacturer’s track record, technical support, and product documentation like certifications, test reports, and warranties should all be roughly examined.

How do geosynthetics help address environmental challenges like soil erosion, landfills, and contaminated sites?

Geosynthetics are crucial in tackling environmental challenges like soil erosion, landfills, and contaminated sites. In each scenario, they offer significant benefits:
