Crafted from PSB1080 high-strength fine-rolled ribbed steel (yield strength ≥1080 Mpa, ultimate tensile strength ≥1230 Mpa), the anti-floating anchor features a full-thread structure for seamless connection and deep anchoring (5-30m customizable). Key design highlights:
- Full-thread design: Ensures stable connection with couplers, allowing flexible extension of anchoring depth without strength loss.
- High uplift capacity: 100-500 KN customizable anti-floating load, 40% higher than standard anchors—effectively resisting structural uplift from groundwater pressure.
- Corrosion resistance: Multiple surface treatment options to adapt to harsh environments:
- Hot-dip galvanizing (430-600g/㎡): Ideal for humid basements and inland projects (complies with ISO 12944 C4 standard).
- Epoxy coating: Superior protection against salt spray, acidic/alkaline soil—perfect for coastal and coastal projects (meets C5-M corrosion standard).
- Grout compatibility: Works with cement grout, chemical grout, and polymer grout, forming a solid bond with rock/soil to enhance load transfer.
The product is ISO9001 certified and complies with international standards including GB/T 20065 (China), ASTM A722 (North America), EU CE (Europe), Australian AS 10125, and Russian GOST 25900. This ensures seamless integration into cross-border projects, avoiding rework due to standard mismatches.
Our anti-floating anchors are tailored to diverse geological and project types worldwide, solving region-specific uplift challenges:

- Regions: Siberia (Russia), Northern Canada, Middle East (Gulf Countries)
- Application: Arctic infrastructure, desert oasis projects
- Solution: Low-temperature resistant PSB1080 anchors (25-32mm diameter, 10-15m depth) with anti-freezing grout—stable performance in -40℃ to 60℃ environments.
- PSB1080 high-strength steel core + pressure grouting (2.5-4 MPa) forms a "steel-grout-rock/soil" integrated system, ensuring uniform load transfer and 100-500 KN anti-floating capacity.
- Deep anchoring design (up to 30m) penetrates unstable shallow soil layers, anchoring into stable rock/soil for long-term reliability.
- Full-thread connection allows quick assembly without welding, reducing construction time by 30% compared to traditional anchors.
- Lightweight design (per meter weight ≤20kg) simplifies transportation and on-site handling, lowering labor costs.
- Customizable load, diameter, and depth to match project-specific uplift force and geological conditions.
- Corrosion-resistant surface treatments and high-quality steel material ensure service life ≥25 years, reducing maintenance and replacement costs.
- Tools Required: Core drill (25-50mm bit), high-pressure grouting pump (≥2.5 MPa), torque wrench (≥200 N·m), depth measuring tape, compressed air device (≥0.6 MPa), grout mixer, water pump (for high groundwater regions).
- Material Preparation: High-strength anti-floating anchors, couplers (for extended depth), grout (cement/chemical/anti-corrosion type), centralizers, and water-stopping rings.
- On-Site Check: Conduct geological survey to confirm groundwater level, soil/rock type, and uplift force; mark drilling positions (spacing: 1.5-3m, hole diameter 10-15mm larger than anchor diameter).
- Drilling: Drill vertical holes (angle deviation ≤5°) to the designed depth. Use diamond-tipped bits for hard rock (Europe/North America) and spiral bits for soft soil (Southeast Asia).
- Hole Cleaning: Blow holes repeatedly with compressed air from bottom to top to remove dust and loose particles. For high groundwater regions, use a water pump to drain water before cleaning.
- Anchor Insertion: Insert the anti-floating anchor into the hole, using centralizers to keep it centered (ensures uniform grout coverage). Connect multiple anchors with couplers if extended depth is required.
- Pressure Grouting: Inject grout from bottom to top at 2.5-4 MPa pressure—avoid voids. For coastal projects, add anti-corrosion admixtures to the grout; for permafrost regions, use low-temperature resistant grout.
- Curing: Allow grout to cure for 7-14 days (20-25℃); extend to 21 days in humid or low-temperature environments.
- Load Testing: Use a hydraulic jack to verify uplift resistance (≥1.2× designed load). Mark qualified anchors for project acceptance.
- Coastal Soft Soil Regions (Southeast Asia/Australia): Use epoxy-coated anchors and anti-corrosion grout; increase anchoring depth by 30% to penetrate stable soil layers; avoid drilling during high tide to prevent hole collapse.
- High Groundwater Regions (Middle East/Europe): Drain groundwater before drilling; install water-stopping rings at the anchor top to prevent water seepage into the foundation; use chemical grout for better adhesion in water-rich strata.
- Hard Rock Regions (North America/Canada): Use diamond-tipped drills for deep, precise holes; pre-grout fractured rock to seal gaps—ensures uniform load transfer and avoids local stress concentration.
- Permafrost Regions (Siberia): Pre-heat drill holes to 5-10℃ with a portable heater; use anti-freezing grout and low-temperature resistant steel anchors; complete installation within 12 hours to prevent re-freezing.
