Yantai Gaea's expansive mortar (expanding grout for breaking rock) is a non-explosive, eco-friendly slurry poured into drilled holes that expands overnight to fracture marble, granite, limestone, concrete and boulders without noise, vibration or flyrock. Expanding grout for breaking rock enables precise, safe quarrying, mining and demolition, cutting costs and hazards. Choose expanding grout for breaking rock where explosives are banned.

The patented 80-Type Crawler Road Cutting Machine combines a four-cylinder turbocharged 490KZ engine with 24V electric remote control. Compact at 1650×1050×1550 mm and 800 kg, it cuts up to 50 cm deep with 90–120 cm single-cut spacing — ideal for deep trenching and road rehab.

57-Type Crawler Road Cutting Machine is a patented, crawler-mounted cutter powered by a four-cylinder 490K engine with 24V electric remote control and onboard water spray. Compact (2200×1160×1400 mm, 700 kg), it cuts up to 30 cm deep with 50–100 cm single-cut spacing.

Yantai Gaea's expansive cement, also sold as expanding grout for breaking rock, provides non-explosive, eco-friendly rock and concrete fracturing with strong controlled cracking force. Expanding grout for breaking rock cuts heavy-equipment costs, boosts safety and precision, and suits mining, tunneling and roadwork. Choose expanding grout for breaking rock for efficient, low-impact excavation.

Gaea's electric-powered hydraulic stone splitter pairs electric drive with hydraulic force for precise, low-emission rock breaking in mining and construction. The hydraulic stone splitter delivers continuous, controllable power, safety interlocks and after-sales support. Our hydraulic stone splitter system uses pump-driven splitting rods for silent, fast (5–12s) splitting of granite, basalt and limestone.

The WG-45 excavator drill rig combines a rock drill and excavator for powerful rock drilling, versatile excavation and precise control. This excavator drill rig uses high-frequency piston impact crushing for efficient penetration; durable components, an ergonomic cab and safety features cut downtime and fatigue. Yantai Gaea’s WG-45 excavator drill rig suits mining, tunneling and construction.

The hydraulic splitter is a machine that uses the wedge principle (which can release a great splitting force outward in the narrowest hole) for the mining of quarry blocks.
The hydraulic splitting machine grasps the brittleness of rock and concrete, and is designed using the principle of wedge-it can release a great splitting force outward in the narrowest hole.

The hydraulic rock splitting machine uses hydraulic pressure to swell and crack the rock without splitting and breaking the rock without vibration and sound.we are a hydraulic rock splitter manufacturers china.

Expansive cement, a vital material in construction, expands during hydration, countering shrinkage of regular cement. Its performance is remarkable: creating self-stress in concrete, enhancing impermeability, and bolstering long-term durability. With various types like Portland and sulfoaluminate, it addresses diverse needs from waterproofing to self-stressing reinforced pipes. Efficient packaging and storage are crucial for its longevity. However, challenges like slump loss during hot weather necessitate careful handling.
