Material Testing

Rox Engineering provides in-place density and moisture testing by both nuclear and sand-cone methods. Rox Engineering conducts laboratory testing of fill materials to determine moisture density relationships, soil plasticity, and other engineering characteristics. Proper management is essential to construct a high quality structural fill. Rox Engineering engineers conduct and review laboratory testing of fill materials to determine moisture density relationships and soil plasticity characteristics. Simultaneously, our project engineer and/or geologist will perform sub grade observation to verify removal of organic and soft soils. Compaction and non-destructive testing will be performed by experienced and qualified technicians to verify in-place density of soils.
