What Is Grouting Mortar and Why It Matters

Grouting mortar is a high‑flow cement‑based material that fills voids and anchoring gaps with precision. It is used to:

▸
Level and secure machinery foundations
▸
Anchor steel reinforcements and bolts
▸
Install bridge bearings and rails
▸
Repair cracks and voids in concrete
▸
Fill ducts for pipelines and cables
▸
Provide non‑shrink support beneath structural components

Performance Additives

To keep these mixtures stable and pumpable, modern formulations rely on performance additives that enhance rheology, limit sedimentation, and maintain bond strength from day one.

⚙️ Technische Uitmuntendheid

How LANDU Additives Improve Grouting Performance

01
💧

Cellulose Ether (HPMC / HEMC)

For Cohesive Flow and Optimized Workability

Acts as a water‑retaining and rheology‑control agent to stabilize mixes and maintain lubrication through the pump line.

Technical advantages:

  • • Consistent hydration and stable flow through formwork
  • • Prevents segregation and bleeding even at low W/C ratios
  • • Extends open time for precision placement
  • • Improves surface finish and anti‑shrink behavior
02
🛡️

Redispersible Polymer Powder (RDP)

For Adhesion, Flexibility and Long‑Term Bond Integrity

RDP modifies the cement matrix to improve bond to concrete and steel while adding ductility for crack resistance.

Technical advantages:

  • • Higher adhesion to substrates and reinforcement
  • • Better tensile and bending resistance under load
  • • Improved freeze‑thaw durability and fatigue strength
  • • Enhanced structural flexibility to prevent micro‑cracks
🔬

Synergistic Performance

Used together, HPMC + RDP create a grout that is fluid enough for perfect filling and strong enough to carry heavy loads without shrink or segregation.

Q5

Can HPMC and RDP be used together?

✓

Yes – the combination offers synergy: stable flow, higher adhesion, better crack control, and improved durability. LANDU provides the right ratio guidance.

Q6

How to prevent bleeding and segregation in grout mixes?

🛡️

Optimize HPMC dosage, use RDP 4025N, add micro PP fibers for reinforcement, adjust aggregate gradation, and reduce water content with a PCE superplasticizer.

Q7

How do LANDU additives improve pumpability for vertical grouting?

⬆️

They create uniform viscosity and self‑lubrication within pipes, reducing friction and pressure drops for consistently smooth delivery even at 30–50 m heights.
