High-Strength Anti-Floating Anchor for Groundwater Engineering

High groundwater levels, coastal soft soil, and deep basement projects around the world require reliable anti-floating solutions. From European high-rises and Southeast Asian coastal developments to Middle Eastern infrastructure and Australian waterfront buildings, Jiufu’s high-strength anti-floating anchors provide outstanding uplift resistance (100–500 KN) via deep anchoring and precision grouting. They effectively eliminate structural floating risks while ensuring high construction efficiency.

1. Core Product Characteristics

1.1 Premium Material & Anti-Floating Core Design

Our anti-floating anchor is manufactured from PSB1080 high-strength, fine-rolled, ribbed steel, with a yield strength of ≥1080 MPa and an ultimate tensile strength of ≥1230 MPa. It features a full‑thread structure for reliable connection and deep anchorage, with customizable lengths from 5 to 30 meters.
Key design advantages:

Full-thread design:

Ensures a stable connection with couplers and allows for the flexible extension of anchoring depth without compromising strength.

High uplift capacity:

Customizable anti‑floating load from 100 to 500 KN, 40% higher than standard anchors, effectively resisting structural uplift caused by groundwater pressure.

Excellent corrosion resistance:

Hot‑dip galvanizing (430–600g/㎡): Ideal for humid basements and inland projects, complying with ISO 12944 C4.

Epoxy coating: Provides outstanding protection against salt spray and acidic/alkaline soil, suitable for coastal projects and meeting the C5‑M corrosion standard.Multiple surface treatments available for harsh environments:

Wide grout compatibility:

Works with cement grout, chemical grout, and polymer grout to form a solid bond with rock and soil, improving load transfer efficiency.

  • 1.2 Global Standard Compliance

    The product is ISO9001 certified and meets major international standards, including GB/T 20065 (China), ASTM A722 (North America), EU CE, Australian AS 10125, and Russian GOST 25900. This ensures smooth application in cross‑border projects and avoids rework caused by standard mismatches.

2. Global Anti-Floating Application Scenarios

Our anti‑floating anchors are designed for diverse geological conditions and project types, solving regional anti‑floating challenges worldwide.

2.1 High-Rise Basements & Underground Structures

Applications: Dams, irrigation facilities, reservoir banks
Solution: Hot‑dip galvanized anchors with diameters of 32–40mm and depths of 20–30m, using cement grout to withstand long‑term water pressure and humid environments.

2.4 Permafrost & High-Groundwater Regions

Regions: Siberia (Russia), Northern Canada, Middle East (Gulf Countries)
Applications: Arctic infrastructure, desert oasis projects
Solution: Low‑temperature resistant PSB1080 anchors with diameters of 25–32mm and depths of 10–15m, using anti‑freezing grout. Stable performance from ‑40℃ to 60℃.

3. Technical Advantages

3.1 Superior Uplift Resistance

The PSB1080 high‑strength steel core combined with pressure grouting (2.5–4 MPa) forms an integrated steel‑grout‑rock/soil system, ensuring uniform load distribution and 100–500 KN uplift resistance.
Deep anchoring up to 30m penetrates unstable shallow soil and anchors into stable rock or soil for long‑term reliability.

3.2 Efficient Installation & Cost Savings

Full‑thread connection allows quick assembly without welding, reducing construction time by up to 30% compared with traditional anchors.
Lightweight design (≤20kg per meter) simplifies transportation and on‑site handling, lowering labor costs.

3.3 Wide Adaptability

Compatible with standard construction equipment worldwide (drills, grouting pumps), no special tools required.
Load capacity, diameter, and anchoring depth can all be customized to match geological and structural requirements.

3.4 Long Service Life

Corrosion‑resistant surface treatments and high‑grade steel ensure a service life of over 25 years, reducing maintenance and replacement costs.

4. Step-by-Step Installation Guide (Regional Adaptation Included)

4.1 Pre-Installation Preparation

Tools: Core drill (25–50mm), high‑pressure grouting pump (≥2.5 MPa), torque wrench (≥200 N·m), depth tape, compressed air device (≥0.6 MPa), grout mixer, water pump (for high‑groundwater areas).
Materials: High‑strength anti‑floating anchors, couplers, grout, centralizers, water‑stopping rings.
On‑site survey: Confirm groundwater level, soil/rock type, and required uplift force. Mark drilling positions (spacing 1.5–3m, hole diameter 10–15mm larger than anchor).

4.2 Standard Installation Steps

Drilling: Drill vertical holes with angle deviation ≤5°. Use diamond bits for hard rock and spiral bits for soft soil.

Hole cleaning: Clean holes with compressed air from bottom to top. Drain water first in high‑groundwater areas.

Anchor insertion: Insert the anchor with centralizers to keep it centered. Use couplers for extended depth.

Pressure grouting: Inject grout bottom‑up at 2.5–4 MPa to avoid voids. Use anti‑corrosion or low‑temperature grout as needed.

Curing: Cure for 7–14 days at 20–25℃; extend to 21 days in humid or low‑temperature environments.

Load testing: Use a hydraulic jack to verify uplift resistance (≥1.2× design load) for project acceptance.

4.3 Regional-Specific Precautions

Coastal soft soil areas: Use epoxy‑coated anchors and anti‑corrosion grout; increase depth by 30%. Avoid drilling during high tide.

High groundwater areas: Drain water before drilling; install water‑stopping rings; use chemical grout.

Hard rock areas: Use diamond drills; pre‑grout fractured rock to prevent stress concentration.

Permafrost areas: Preheat holes; use anti‑freezing grout; finish installation within 12 hours.
