Description

Diamond Drilling, Stitch Drilling, Rotary Drilling.

Demon Drillers Ltd were contracted by Sirius to provide approximately 4000 No 32 mm diameter holes to a depth of 300mm through reinforced concrete walls.
Brackets were then used to hold supporting cross beams and whaling beams to support the dig walls.
Concrete packing pads were stitch drilled to allow for the removal and recycling of the whaling beams.

All power and water were supplied by Demon Drillers Ltd. Minimum daily production levels required by Sirius were adhered to throughout, although on most site visits production was significantly higher than target.

All works completed on time and to budget.
