Engineered to deliver high torque, structural stability, and extreme efficiency in challenging geotechnical strata.
Understanding why under-reamed piles are normally bored following initial pilot piles and their significance in deep foundation systems.
An under-reamed pile is a specialized type of bored cast-in-situ concrete pile characterized by one or more bulbs (under-reams) expanded along its shaft. These bulbs significantly increase the load-bearing capacity of the pile by expanding the base resistance (end-bearing) and offering anchor capability against uplift forces. Under-reamed piles are particularly essential when dealing with expansive soils, such as black cotton soil, clayey deposits, or strata prone to seasonal volume changes.
In standard construction practices, under-reamed piles are normally bored following the main pile shaft drilling. The mechanical process follows a sequential phase:
Deploying under-reamed bored piles provides immense engineering benefits compared to traditional straight-shaft piles:
By multiplying the effective base area by up to 2.5 to 3 times the shaft diameter, the structural load is distributed across a much larger soil interface. This makes it possible to build heavy, multi-story buildings, high-voltage transmission line towers, and industrial plants on ground that would otherwise require deep and highly expensive replacement strategies.
SINOVO Group is a professional supplier of construction machinery equipment and construction solutions. We engage in the field of construction machinery, exploration equipment, import and export product agency, and construction scheme consulting, serving the world's leading construction and exploration projects.
As early as the early 1990s, the backbone members of the company began serving the construction machinery industry. Through 20+ years of persistent innovation and development, the company has established long-term strategic alliances with top global equipment manufacturers, earning numerous accolades in China's engineering machinery export sectors.
We establish a complete after-sales service system, offering free debugging, operator training, and maintenance during the warranty period.
Our experienced engineering and trade experts ensure that all equipment specifications precisely match your geological project needs.
We back our drilling equipment with a robust 12 to 24-month warranty covering main components, supported by global spare parts networks.
Delivering high-tech, reliable heavy machinery solutions across all five continents.
Beijing Sinovo International & Sinovo Heavy Industry Co. Ltd. are ISO9001: 2015 certified manufacturers. In 2010, the group invested in a massive production and manufacturing base inside the Hebei Xianghe Emerging Industry Demonstration Zone. This facility occupies 67 mu with a total investment of 120 million yuan. Situated just 100 kilometers from Tianjin Port, this strategic industrial hub reduces logistics and transportation overhead, passing substantial cost benefits directly to our wholesale partners and distributors.
SINOVO Heavy Industry stands at the absolute vanguard of electronic-hydraulic control and drive systems. Through our alliance with premium parts manufacturers such as Caterpillar (CAT), our heavy piling machinery leverages global CAT service networks. This means local structural contractors from Riyadh to Singapore can execute complex foundation works with minimal downtime.

SINOVO Heavy Industry traces its foundation roots to the early 1990s. Recognizing the fast-paced growth in global civil construction, we expanded operations internationally by forming TEG Far East in Singapore in 2008. This pivot empowered us to capture major public infrastructure projects in Singapore, Malaysia, and Indonesia.
Our core R&D team consists of mechanical engineers who hold multiple patents on hydraulic control, continuous flight auger (CFA) design, and diaphragm wall grab telemetry. We do not just build rigs; we construct complete mechanical ecosystems tailored for challenging underground projects.
Tested and verified under world-leading manufacturing standards to guarantee safety and performance.

We back our advanced machinery with operational and technical support to ensure low downtime and safe onsite execution.
For each equipment inquiries, we supply in-depth technical breakdowns and strata compatibility analysis. This ensures that the selected rig, whether it is a low-headroom TR80S or a high-depth CFA system, matches your project specifications. All rigs undergo load and system calibration checks before leaving the factory.
We work within a streamlined delivery window of 10 to 15 days for standard equipment configurations. For highly customized projects requiring specialized belling buckets or modifications, delivery timelines are adjusted to cover comprehensive custom testing. We provide regular manufacturing updates.
We deploy service engineers directly to your job site for 1-2 weeks of initial setup and operator training. All normal wear parts are covered and replaced free of charge during the warranty. Furthermore, our CAT-chassis-based machinery enjoys global maintenance and support through local CAT service centers.
