Dry mix mortar, also known as specialty mortar, is widely used in applications involving powdered materials and cement-based formulations. It offers consistent quality, easy application, and improved performance across multiple construction needs.
Its main application areas include:
– Cement mortar and high-performance concrete for structural and decorative work.
– Cement-based self-leveling compounds for smooth, even flooring.
– Precast components and concrete products, ensuring strength and durability.
– Grouting solutions such as cement-based grouting, pressure grouting, and injection grouting for sealing and reinforcement tasks.
LANDU’s waterproof mortar solutions are designed for a wide range of everyday construction needs, offering long-lasting protection against water intrusion. Common application scenarios include:
•Basements – Anti-seepage and leak repair to prevent moisture damage
•Roofs – Waterproof layers to protect against rain and weather exposure
•Interior & Exterior Walls – Leak-proofing and surface sealing
•Swimming Pools & Water Pools – Ensuring watertight containment
•Tunnels & Civil Defense Projects – Protecting underground structures from water ingress
•Grain Warehouses, Kitchens, Bathrooms – Safeguarding moisture-sensitive areas
•Factories & Enclosed Balconies – Providing durable, water-resistant protection for industrial and residential settings
With LANDU’s waterproofing additives, these structures benefit from enhanced durability, reduced maintenance, and extended service life.
Flowable mortar refers to mortar with high fluidity, designed for easy placement without the need for vibration or extensive finishing. It’s commonly used in various daily construction applications where smooth flow and self-compaction are essential.
Typical Daily Applications of Flowable Mortar Include:
•Cementitious Self-Leveling Compounds
Used for creating smooth, level subfloors before installing flooring materials.
•Grouting
Ideal for filling voids around tiles, anchors, or structural elements.
•Self-Compacting Repair Mortar
Applied in repairing concrete surfaces, columns, and beams without the need for mechanical compaction.
•Underlayment for Equipment and Machinery
Provides strong, level support with easy flow into confined spaces.
At LANDU, we offer advanced additive solutions to enhance the performance, flowability, and durability of all types of flowable mortar formulations.
HPMC (Hydroxypropyl Methylcellulose) works in mortar primarily by improving water retention and enhancing workability. As a high-molecular-weight polymer, HPMC forms a mesh-like structure that traps mixing water and encapsulates cement particles. This prevents rapid moisture loss, allowing for slower, more controlled cement hydration, which improves bonding and reduces cracking.
It also acts as a thickening agent. The long polymer chains and hydroxyl groups form a stable film that creates tiny, evenly distributed air bubbles throughout the mix. These bubbles help prevent aggregate sedimentation and improve mortar consistency. As a result, HPMC contributes to better cohesion, smoother application, and long-lasting performance—especially in dry mix and polymer-modified mortar systems.
HEMC (Hydroxyethyl Methyl Cellulose) plays a crucial role in improving water retention and workability in mortar formulations. As a high-molecular polymer, HEMC forms a mesh-like structure that locks in mixing water and coats cement particles. This structure slows down moisture evaporation and allows for better cement hydration, leading to improved bonding strength and reduced surface cracking.
HEMC also acts as a reliable thickener. Its long-chain molecular structure introduces tiny, evenly dispersed air bubbles that prevent aggregate settling and help maintain a uniform mixture. This results in a stable, easily workable mortar with enhanced spreadability—ideal for both dry mix mortars and polymer-modified systems.
