The GRR sheet method is a technique that involves laying geotextiles within a crushed stone base of a specified thickness. This method provides reinforcement effects near the surface due to the crushed stone and deformation restraint effects from the sheet, resulting in enhanced bearing capacity. After construction, nothing remains deep underground, so there are no underground installations that arise after the demolition of buildings. 【Features】 - No contamination of residential foundations or groundwater occurs. - It can be implemented within the flow of foundation work, so no special procedures are necessary. - Good workability and the ability to work in rainy weather prevent delays in the workflow. - The work is free from vibration and noise, so it does not disturb the neighbors. - Construction is possible in areas where heavy machinery cannot access. - The improvement effects after construction can be confirmed using surface wave exploration methods. *For more details, please request materials or view the PDF data available for download.
