Ground Bearing Slabs on Fill
Ground Bearing Slabs on Fill
(OP)
We often used a guide set by the local authority and housing building association of changing to suspended slabs in a house when there is over 600mm Dp. of fill material.
I am now looking at a large factory building and will have aprox: 600mm - 1500mm of fill below the floor. I am considering using a ground bearing slab but producing a spec. for the quality and compaction required for the imported granular fill. Can any one advise where I can get detailed info on this for the UK?

RE: Ground Bearing Slabs on Fill
First look at your soil conditions and the type of fill material you want to use. You will use select structural fill, it should be granular, and should not contain more than 10 percent passing a 0.074mm sieve.
Next, the soil should be placed in loose layers that do not exceed 300mm, each. Compact the soil to at least 95 percent of the maximum dry density determined through an acceptable moisture-density relationship standard used for your soils in your area. Here, we specify at 95% of the Modified Proctor maximum dry density.
Place and compact each succeeding layer until you have achieved the fill that you need.
Look for British Standard BS 1377-4 on the compaction testing, both field and laboratory.
