Engineered to excel in demanding geological strata, from Sofia's dense clay basins to the Danube River's loess deposits.
Bulgaria is undergoing a monumental phase of infrastructural updates driven by the European Union’s National Recovery and Resilience Plan (NRRP) and major Trans-European Transport Network (TEN-T) corridor projects. The expansion of the Sofia Metro (particularly lines 3 and 4), structural reinforcements of Danube river port installations, and massive road artery developments such as the Struma and Hemus Motorways demand highly specialized foundation equipment and custom tooling accessories.
Local contractors are facing distinct geological challenges. The northern Danube Plains features highly collapsible loess soils, which require massive soil compaction, stabilization, and deep pile boring. In contrast, the southern Rhodope and Balkan mountain corridors require drilling through high-strength volcanic rocks and highly variable, seismically active strata. To address these demands, construction firms require tools with high-strength alloys, custom configurations, and compliance with European construction safety regulations.
"Choosing the appropriate drilling accessories and piling machinery is critical to reducing operating costs in Bulgaria's diverse and demanding geological structures."
How SINOVO Group bridges heavy manufacturing expertise with European onsite execution requirements.
Our products fully adhere to EU safety directives and EN 16228 standards for drilling and foundation equipment. This ensures seamless integration on domestic projects under Eurocode 7 (Geotechnical Design) and Eurocode 8 (Seismic design).
Strategically positioned production centers with reliable shipping routes to the Port of Burgas and Port of Varna. Direct container transport ensures reduced logistics costs and fast customs clearance via Class-A export certifications.
Our rotary drilling rigs utilize globally recognized components, such as Caterpillar (CAT) undercarriages and Cummins engines. This enables local Bulgarian contractors to access domestic CAT service networks for maintenance.
Preserving standard catalog lines with customized adaptation for Bulgarian geological conditions.
SINOVO Group is a global supplier of construction machinery, exploration equipment, and deep foundation engineering solutions. Serving the piling and mining industries since the early 1990s, the company has integrated design, engineering, and export operations to support global infrastructure development.
Over more than 20 years of technical development and system refinement, we have built alliance partnerships with top-tier equipment suppliers in China and engineering distributors in Europe, Asia, and Africa. We focus on pile construction machinery, hoisting equipment, water well drilling rigs, and advanced geological exploration equipment, exporting to more than 120 countries and regions.
All products hold ISO9001:2015, CE (Machinery Directive), and GOST certifications. To support our European and international clients, our operations in Singapore, Dubai, and Algeria provide technical support, spare parts storage, and field services.
Beijing Sinovo International & Sinovo Heavy Industry Co., Ltd. operate an ISO9001:2015 certified production complex covering 7,800 square meters. The facility is equipped with over 50 advanced manufacturing machines, including CNC machining centers, automated welding robots, and hydraulic test benches.
In 2010, SINOVO established an additional heavy production base in the emerging industry demonstration zone of Xianghe, covering 67 mu (approx. 44,000 sqm) with an investment of 120 million RMB. Located 100 kilometers from the Port of Tianjin, this facility reduces shipping and logistics overhead for international shipments.
Our annual production capacity includes:
Pre-sale technical configuration, on-site commissioning, and post-sales parts supply to ensure high machine uptime.
We provide a one-year warranty for our drilling and piling rigs. During the warranty period, we offer free installation, commissioning support, operator training, and maintenance servicing. Critical replacement parts are shipped from global service depots to minimize downtime on the job site.
We provide complete engineering reviews, geological suitability analyses, and custom accessory selections to ensure the equipment meets project specifications. Third-party inspections are supported for all custom orders.
We deploy service technicians to client job sites to manage equipment assembly, perform commissioning tests, and conduct operator training programs lasting 1 to 2 weeks.
