The subject of this article is to assess the impact of a new branch of construction products, such as geosynthetics, on reducing the negative environmental impact of the construction sector. Recent decades have shown a rising awareness of advancing degradation of natural environment as well as overuse of natural resources caused by humanity. This is heavily caused by construction sector impact, as it follows growing population needs in householding, civil and industrial infrastructure. Civil engineering was discussed with examples of investments with negative and positive impact on the environment. Later, classification, definitions, functions, and properties of geosynthetics were presented, with special focus on geogrid applications. Working platform for crawling crane and heavy haul road were designed, in order to compare the results of traditional approach and polymeric geogrid usage in specified scenarios. The usage of geosynthetic product allowed to reduce the required thickness of the platform by 670 mm, while maintaining ultimate bearing capacity and factor of safety values on the same level as traditional solution. In the case of the design of the road under passage of heavy transportation, similar results were obtained, with the reduction of thickness of the platform equal to 655 mm. Carbon dioxide (CO2) consumption decreased by 50% in both cases.
