Explore our premium foundation tar sprayers, asphalt distributors, and heavy structural engineering equipment designed for maximum durability and precision.
Modern civil infrastructure, underground transport corridors, commercial high-rise basements, and heavy industrial facilities rely heavily on subterranean structural integrity. Moisture ingress, acidic soil erosion, hydrostatic pressure, and chemical deterioration pose persistent threats to concrete foundations. Securing a structure against long-term water degradation demands high-performance bituminous membranes and specialized heavy-duty application equipment.
As a leading Foundation Tar Sprayer Manufacturer & Supplier, HEM Group (HME TOP Machinery Equipment Co., Ltd.) delivers cutting-edge thermal spraying solutions designed to process rubberized asphalt, hot-applied bitumen, emulsified tar compounds, and modified liquid waterproof membranes. Engineered to maintain consistent viscosity control and uniform atomization, our foundation tar spraying machinery bridges the critical gap between material science and structural engineering longevity.
HEM Group was established in 1998, originally founded as Xi'an Hongda Communications Technology Co., Ltd. by a distinguished panel of professors from Chang'an University alongside premier road construction industry experts. As one of China's earliest high-tech pioneers dedicated to independent research and design of road construction and waterproofing machinery, our foundation rests upon deep scientific inquiry.
Our ongoing collaboration with academic research laboratories ensures continuous breakthroughs in mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control systems for asphalt and bitumen processing equipment.
In 2006, the Shaanxi Provincial Department of Science and Technology officially recognized our entity as a certified "High-Tech Enterprise". To keep pace with expanding global market demand, in 2017 HEM Group launched its specialized international sales and export division, HME TOP Machinery Equipment Co., Ltd.
HME TOP Machinery manages international technical exchanges, global logistics, custom OEM manufacturing projects, and comprehensive overseas after-sales technical support across more than 60 countries worldwide.
State-of-the-art modern manufacturing facilities equipped with automated robotic welding, laser cutting, and precision hydraulic assembly lines.
Decades of field experience refining thermal oil heating systems, self-cleaning spray bars, and electronic metering technology.
High-volume manufacturing capability supplying contractors, government agencies, and industrial conglomerates across six continents.
Rapid global urbanization and the expansion of deep-underground transport infrastructure (tunnels, subways, subterranean parking complexes) have elevated the stringent performance criteria for foundation waterproofing equipment. Traditional manual hand-application of tar or cold-applied paint is no longer viable for large-scale engineering due to non-uniform membrane thickness, labor inefficiency, and severe health hazards caused by solvent emissions.
High-pressure spraying of rubberized bituminous emulsions creates an uninterrupted elastomeric membrane across concrete basement walls, eliminating cold joints and moisture seams under extreme hydrostatic head pressure.
Prevents de-icing salt chemical intrusion and water percolation into reinforced steel structures by applying continuous thick tar-polymer layers prior to backfilling or paving.
Protects heavy manufacturing plants, power generation stations, and water treatment tanks against aggressive groundwater sulfates, soil acids, and structural thermal movement.
Our foundation tar spraying systems are engineered from the ground up to solve the operational bottlenecks inherent to high-viscosity bituminous materials. Below is an engineering overview of our proprietary core subsystems:
Utilizing closed-loop thermal oil jackets powered by dynamic automatic burners, our sprayers heat tar and polymer-modified bitumen uniformly. This prevents localized scorching or material degradation while maintaining exact spraying temperatures between 160°C and 190°C.
High-durability cast-iron positive displacement rotary gear pumps deliver steady volume regardless of viscosity shifts. Equipped with heat-jacketed pump casings, system lock-ups during cold starts are completely eliminated.
Bituminous coal tar and recycled asphalt polymers often contain micro-particulates. Our multi-stage filtration (tank inlet, inline pump screen, and individual nozzle basket filters) ensures continuous, uninterrupted spray pattern delivery.
Integrated electronic control units (ECU) dynamically sync pump speed with travel velocity or manual application lance output. Operators can pre-set precise application rates (e.g., 1.5 kg/m² to 4.0 kg/m²) with ±1.5% accuracy.
Different climate zones and geographic topographies demand customized foundation waterproofing protocols. HEM Group equipment is adapted for extreme environmental operational envelopes worldwide.
In cold regions like Russia and Uzbekistan, foundation footings endure harsh freeze-thaw cycles. Our sprayers apply heavy SBS-modified rubber bitumen that remains flexible at temperatures down to -30°C without cracking.
Deployments in Malaysia, Indonesia, and Sri Lanka require fast-setting asphalt emulsions for foundation tanking before monsoon rain inundation. Our dual-fluid spray lances allow simultaneous catalyst injection for instant setting.
In hot environments like Kenya, Ghana, and South Africa, thermal stability is key. Our heavy insulated double-walled tanks maintain high binder temperature without over-burning diesel fuel resources.
In addition to our industry-leading foundation tar sprayers, HEM Group supplies a complete end-to-end machinery ecosystem for heavy road building, mining aggregate processing, and foundation construction:
Pavement milling machines, intelligent bitumen distributors, asphalt spray pavers, self-propelled chip spreaders, slurry sealers, and road wideners designed for asphalt rehabilitation.
Heavy excavators, versatile mini excavators, backhoe loaders, wheel loaders, road rollers, and special walking excavators ("Iron Spider-Man") for emergency rescue and severe terrain foundation work.
Mobile jaw crushers, mobile primary screens, vibrating screeners, and mobile roller crushing plants for quarry aggregate production and concrete ballast preparation.
Acquiring industrial capital equipment demands absolute confidence in regulatory compliance, build customization, and ongoing field support. HEM Group prioritizes client operational uptime through robust structural standards.
We provide tailored equipment design to meet specialized regional requirements: modified tank capacities (from 1,000L to 15,000L), customized engine emissions compliance (Euro Tier 3 / Tier 4 Final / Stage V), truck chassis mounting options, or self-propelled crawler chassis designs.
Our dedicated international trade team handles all logistics export compliance, international certificate of origin documents, bill of lading documentation, customs clearance, and sea freight containerizing for seamless delivery worldwide.
We maintain active service support teams, local spare part stocking hubs, and regional technical partnerships across Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka to provide immediate field service response.
Our technical team provides round-the-clock remote electronic troubleshooting. For large-scale municipal or enterprise projects, expert technicians are dispatched on-site for machine setup, calibration, and operator safety certification.
As industrial automation, IoT telematics, and eco-friendly machinery standards evolve, HEM Group continues to push the boundaries of bituminous spray engineering.
Integrating machine-vision sensors to automatically scan foundation wall surface roughness and adjust individual spray nozzle flow rates in real-time, optimizing bitumen consumption.
