This week the contractor finalized on the masonry work in the foundation. Depending on the height prescribed in the drawing, the foundation had about 4 courses in the higher sides and up to 7 courses in the lowest land levels.
Backfilling
The backfilling also took place this week. The contractor returned all the red soil into the wall space, then left a gap of about 1 foot to the top. the 1 foot was filled with Hardcore then levelled with a hammer they then added quarry dust.
Compacting
They used a roller compressor to compact the hardcore and quarry dust then put a layer of DPM and BRC . They put a formwork made of wood (mukima 6*1) around the ground floor in preparation for the slab.
Materials
BRC A142 2 rolls
DPM 2 rolls
Quarry dust 20t
Hardcore 40t
Ballast 20t
Rock sand 20t
Cement 120 bags
In week 5, we hope to start walling.
