Waterproof Mortar Additives

LANDU Construction Chemicals

High‑Performance Polymer Additives for Cementitious Waterproofing Systems

❓

What Is Waterproof Mortar?

Waterproof mortar is a cement‑based mixture designed to prevent moisture penetration while maintaining strong adhesion and durability. Commonly used in basements, bathrooms, water tanks, swimming pools, and exterior walls, it forms a dense layer that resists water ingress.

⚡

Advanced Formula

Unlike ordinary mortar, waterproof mortar contains functional chemical additives—such as cellulose ether (HPMC / MHEC), redispersible polymer powder (RDP), ve polycarboxylate superplasticizer (PCE)—that enhance impermeability, flexibility, and long‑term strength.

Why Additives Matter in Waterproof Mortar

Performance additives are crucial for achieving a truly waterproof, crack‑resistant mortar. They modify the cement matrix to improve bonding, flexibility, and surface durability.

01
💧

HPMC / MHEC

Selüloz Eter

  • • Retains moisture for full cement hydration
  • • Improves workability, viscosity, and anti‑sag performance
  • • Extends open time for convenient application
  • • Enhances adhesion strength and surface consistency
02
🛡️

RDP

Yeniden Dağılımlı Polimer Tozu

  • • Boosts tensile and bonding strength
  • • Provides flexibility and crack resistance
  • • Increases hydrophobicity and weather durability
  • • Enhances film formation for long‑lasting waterproof layers
03
⚗️

PCE

Polycarboxylate Ether Superplasticizer

  • • Reduces water demand without affecting workability
  • • Increases mortar density and cohesion
  • • Improves impermeability by minimizing capillary pores
  • • Enhances flow for easier application and compaction
