The growing concern regarding the production of wastes in general with regard to its disposal in increasingly confined urban spaces, and the exhaustion of natural resources and their close relationship with the cost of extraction and transport of materials from dumps even farther from the cities, causes concern in evaluating in more detail the question of waste produced in large urban centres. The purpose of this paper is to check the performance of Construction and Demolition Waste (CDW) when applied to improving soils using compaction piles to replace natural aggregate. With this in mind, it was done an experimental compaction mesh consisting of CDW and conventional piles on site, where it was possible to drill boreholes and perform 15 plate bearing tests. The borehole and plate bearing tests made on the experimental compaction mesh helped confirm good performance of CDW piles compared to conventional piles.
