Drawing file shows the details of foundation in the Autocad DWG drawing file. Compacted sand and lean concrete is provided. Compaction Sand is a course sand that compacts down firm whilst still allowing for drainage and flexibility. It contains slightly more fines than the Washed River Sand, allowing the course grains to lock into each other and compact down stronger. Thank you for downloading the autocad file and other CAD program files from our cadbull website.
