Explore our premium product series engineered for quick deployment, immediate load-bearing support, and high performance in urban civil infrastructure projects across Ho Chi Minh City.
Ho Chi Minh City, the economic powerhouse of Vietnam, is undergoing an unprecedented underground transformation. From the expansive metropolitan metro network (such as the continuous development of Line 1 and Line 2) to deep drainage tunnels designed to alleviate municipal flooding, the city's civil engineering projects face complex challenges. The geological profile of the Saigon River basin consists primarily of thick layers of highly compressible, saturated alluvial clays and soft silt sands.
Underground excavations in these demanding strata require immediate structural support. Unlike passive rock bolts that require extensive curing times for grout or resins, Split Set friction stabilizers exert a continuous radial force along their entire length as soon as they are driven into the pre-drilled borehole. By utilizing mechanical friction to restrict ground movement immediately, our split set stabilizers prevent roof sag, rib spalls, and tunnel convergence, ensuring safe and continuous excavation operations.
A rigorous examination of material properties, testing methods, and structural integration protocols required by international and local Vietnamese regulatory boards.
Procurement directors and geologists managing major infrastructure projects across Southeast Asia look for key compliance metrics. When purchasing friction stabilizer rock bolts, engineers evaluate steel chemistry, structural yield, and corrosion protection. Our products are manufactured to meet and exceed global specifications including ASTM A615 / A615M, ASTM A153 (hot-dip galvanizing standards), and equivalent Vietnamese National Construction Codes (TCVN).
For Ho Chi Minh City’s deep excavation projects, underground acidity levels and heavy marine soil salinity demand exceptional corrosion protection. Shandong E-Way Machine delivers tailored solutions featuring high-durability hot-dip galvanizing or advanced epoxy coatings that prevent oxidation and micro-structural steel degradation. This ensures a long service life, protecting underground retaining structures from environmental degradation.

The performance of a friction rock stabilizer depends directly on the quality of the installation. For HCMC civil projects, adhering to specific mechanical installation protocols ensures optimal anchorage performance:
Friction stabilizers require a carefully calibrated hole size. For example, a 39mm split set bolt typical installation demands a 35mm to 37mm drill bit depending on rock or soil hardness. Too large a hole yields zero friction; too small a hole damages the steel tube during driving.
Using pneumatic or hydraulic rock drill drivers (dolly pushers), the stabilizer is forced into the undersized hole. The installer must maintain constant inline thrust pressure. The continuous spring action of the high-strength steel ensures a permanent mechanical grip along the entire length of the bolt.
A high-strength dome plate is driven firmly against the rock or soil face, distributing loads evenly around the collar of the hole. This prevents face sloughing and secures the surrounding mesh or shotcrete layer in critical tunnel portals.
