Sub base Certification

BGSB practices planning and executing grading operations so that the final soil / sub base elevation is at the theoretical bottom of the slab on ground immediately before commencing concrete operations. Sub-base has three main purposes:

1. It’s a working platform for floor construction activity.
2. It provides level formation for the construction of concrete floor slab.
3. It transmits the load from concrete slab to the sub grade.

BGSB uses TERRATEST® LWD type machine, which is the easy and fast way to check quality of soil / GSB / WMM / WBM compaction at construc­tion sites. BGSB’s sub base expert team performs the test and no load ve­hicle is needed. TERRATEST gauges are fully equipped with GPS system, printer which allows the operator to release the results instantly. BGSB testing equipment combines the best of both worlds: absolute high quality equipment made in Germany and BGSB’s in-house experts conducting the test, live at site.
