What Was the Problem for This Saudi Foundation Contractor?
The customer is based in Riyadh, Saudi Arabia. He runs a foundation and piling company. His core business is residential and commercial foundation work—drilled shafts, piling, and ground improvement. His market covers the Riyadh region, where the ground is hard limestone, the heat is intense, and the construction season is long. His problem was simple. He was winning more contracts, but his old equipment could not handle the work. His old machine was slow, messy, and it was expensive.
He told us: “I was turning down work because I could not drill fast enough. I needed real rotary drilling equipment to stay competitive.”
Why Did He Start Looking for a Rotary Drilling Rig?
The customer faced several serious problems.
- His old auger was too slow. A 10-meter pile took 8–10 hours. Some days he could only finish one pile.
- The ground was difficult. Riyadh has hard limestone and caliche layers. His old auger struggled in hard ground.
- The heat was brutal. His old machine had no cab. His operators suffered in 45°C heat. Productivity dropped.
- Labor costs were rising. He needed 7 workers per shift. Wages in Saudi Arabia have been climbing.
- His old machine was unreliable. Breakdowns were frequent. Repair costs were eating his profit.
He started searching online for a rotary piling rig. He found many options. But he needed a machine that matched his project sizes and his budget. That’s when he found the YG Machinery website.

“If you are still using an old auger, you are losing money. The labor is too expensive. The breakdowns are too frequent. The deadlines are too tight.
