CBGM Marine Anti‑Corrosion Non‑Shrink Grout

One‑sentence intro
A marine‑grade, high‑flow non‑shrink grout engineered to improve durability against chloride and sulfate exposure.


  • High flow, easy placement for base plates, anchor pockets and tight formwork

  • Non‑shrink / micro‑expansion to help reduce cracking risk and improve bearing contact

  • Sulfate resistance (KS ≥ 150) for harsh marine or saline environments

  • Low chloride permeability to limit chloride ingress in coastal structures

Product Introduction

CBGM Marine Anti‑Corrosion Non‑Shrink Grout is developed for coastal structures exposed to high humidity, wet–dry cycling, salt spray, and sulfate-rich environments. The formulation focuses on a denser cementitious matrix and durability indicators to help slow down chloride ingress and reduce sulfate-related deterioration.
The CBGM series includes CBGM‑1/2/3/4 options to match different flow requirements and section thickness (including a pea‑gravel version for thicker placements).

Typical applications

  • Coastal bridges, ports, piers, seawalls, breakwaters

  • Offshore / near‑shore foundations (non‑acidic environments)

  • Anchor bolt grouting, base plates, bearing seats, precast connections

  • Salt‑alkali soil infrastructure and coastal industrial facilities

Product Usage

Application Scenarios

  • Marine and coastal foundations, ports, piers, seawalls, breakwaters

  • Cross-sea bridges, coastal highways, sea-side buildings

  • Salt-alkali soil infrastructure (foundations, pipe galleries, roads)

  • Non‑acidic tunnels and underground structures

Substrate Preparation

  • Remove laitance, dust, oil, weak concrete and loose particles.

  • Pre-wet concrete to SSD condition (no standing water).

  • Ensure steel and embedded parts are clean and properly fixed.

Mixing

  • Use a forced-action mixer or high-shear mixer for consistent dispersion.

  • Add powder to clean water gradually and mix until uniform.

  • Control water addition to meet the specified flow (do not re-temper with extra water).

Placement

  • Seal formwork to prevent leakage; provide vents at high points if needed.

  • Pour or pump continuously from one side to avoid air entrapment.

  • Do not vibrate; allow grout to flow and self-level.

Curing & Protection

  • Protect from wind and direct sun; keep moist curing as required by the project specification.

  • In coastal sites, protect fresh grout from seawater splash before initial set.

Limitations

  • Not recommended for acidic environments unless validated by project-specific testing.

  • Always perform a site trial for large-volume pours or critical marine structures.
