Grouting Mortar Additives
Grouting Mortar Composition and Features
Grouting mortar is a building material that only needs to be mixed with water to be ready to use at the construction site. Grouting mortar is widely used for the multi-step grouting process of equipment foundations that require precise installation and for the anchoring of steel bars and rock bolts in construction and geotechnical engineering. This building material is composed of high-strength aggregate, cement, and additives.
With versatile additives, grouting mortar features excellent fluidity, rapid curing, great corrosion resistance, and fast strength development. It also exhibits tight sealing with minimal shrinkage and micro-expansion. LANDU biodegradable additives introduce no harmful substances, ensuring grouting mortar is an anti-aging and eco-friendly building material without causing pollution to water, surroundings, and humans.
What are Additives in Grouting Mortar Formulas?
Common additives in grouting mortar are plasticizers(water reducers), defoamers, water retainers, accelerators, shrinkage reducers, and reinforcements. As a prominent manufacturer of chemical additives, LANDU is committed to developing optimal solutions and their application in grouting mortar.
LANDU Additives For Your Grouting Mortar
LANDU has established several brands aiming in various directions. Here’s our recommendation for your grouting mortar projects.
LANDERCOLL is a brand under LANDU specializing in cellulose ether. LANDERCOLL Hydroxypropyl Methyl Cellulose (HPMC) and Hydroxyethyl Methyl Cellulose (HEMC) serve as critical water retainers in the grouting mortar. They can also work to improve the workability and adhesion of grouting mortar while preventing shrinkage.
LANDU boasts ACCURATE Redispersible Latex powder to effectively enhance the adhesion and durability of grouting mortar projects. The combination of ACCURATE RDP powders and LANDERCOLL cellulose could significantly upgrade the performance of building materials, especially those exposed to harsh environments like grouting mortar.
NOVASTAR marks LANDU’s pursuit of innovative development. Novastar additives for grouting mortar include Polycarboxylate Superplasticizer, which also functions as a reinforcement, Powder Defoamer, and more. They are used to improve workability and pumpability as well as speeding up early and final strength development.
Core Additives in Grouting Mortar
LANDU NOVASTAR Polycarboxylate Superplasticizer is an innovative and advanced additive designed to reduce the water-to-cement ratio while improving the strength of grouting mortar. It is a fine, free-flowing powder that is highly soluble in water, making it easy to handle and disperse in construction applications. This superplasticizer is specifically formulated with Polycarboxylate-based polymers, which offer exceptional benefits to enhance the properties of concrete and mortar.
Benefits:
- Low dosage, high water reduction
- Good dispersion
- Improved Workability
- Reduced Shrinkage and Cracking
- Enhanced Strength Development

| Powder Defoamer P805 | 0.1-0.5% | Download TDS |
Benefits:
- Foam Control: It is highly effective at controlling and eliminating foam in mortar mixtures.
- Improved Workability: This results in smoother application, better consolidation, and improved finishing of the material.
- Reduced Mixing Time: This can lead to increased productivity.
- Enhanced Bonding: Eliminating excess foam promotes better bonding of mortar to substrates, improving the overall strength and durability of the construction.
LANDU LANDERCOLL HPMC is a non-ionic cellulose ether derived from refined cotton. It is primarily used to reduce water loss and keep the mortar wet enough to prevent shrinkage. HPMC helps the grout flow smoothly through the pipeline, making the application more effortless. The addition of HPMC can improve the viscosity and flexibility of grouting mortar to avoid cracking or peeling off when acted upon by an outside force.
Benefits:
- Enhanced Water Retention
- Improved Workability
- Increased Sag Resistance
- Extended Open Time
- Enhanced Tensile Strength
- Adjusted Water Demand

| LANDERCOLL K40HT | 0.2-0.5% | Download TDS |
LANDU LANDERCOLL HEMC is a non-ionic polymer powder derived from natural polymer cellulose. It has excellent workability and stability. HEMC can be fully dissolved in the grouting mortar to form a uniform slurry, thereby improving the fluidity and stability of the grout.
Benefits:
- Low dosage, high water reduction
- Good dispersion
- Improved Workability
- Reduced Shrinkage and Cracking
- Enhanced Strength Development

LANDU ACCURATE RDP powder is a key additive in grouting mortar to enhance adhesion and durability. It can form a strong adhesive film and ensure the grouting material firmly adheres to the substrates under various environmental conditions without peeling and cracking. This property of our latex powder also prevents the penetration of water and other corrosive substances, thereby extending the service life of grouting mortar.
Benefits:
- Flexibility and Adhesion: Improve the flexibility and adhesion properties of various materials.
- Improved Workability: They make the mix easier to handle, apply, and shape
- Reduced Shrinkage: Significantly reduce shrinkage during drying and curing
- Improved Durability: Making them more resistant to environmental factors
- Temperature Tolerance: Improve the freeze-thaw resistance of construction materials
