Waterproofing

Binders for superior flexible concrete, bitumen and liquid applied membrane (LAM) waterproofing applications

Synthomer is a specialist supplier of water-based binders optimised for use in waterproofing products. Our wide range of carboxylated styrene butadiene rubber (XSBR), high-styrene styrene butadiene rubber (HS-SBR) and acrylic dispersions deliver excellent performance across the various technologies applied in the waterproofing industry, such as flexible concrete, bitumen and liquid applied membranes (LAM).

Liquid applied membranes: essential to modern building construction

Liquid-applied membranes (LAM), also known as ´damp-proof’ membranes´ (DPM), have become increasingly important in new building construction and the renovation of older ones. Synthomer’s binders will allow you to formulate ready-to-use compounds that provide seamless protection of moisture-sensitive substrates, well balanced mechanical properties, high flexibility, good crack-bridging properties and low water vapour permeability.

Our Lipaton SB 47B40 for thick-layer coatings has been an industry standard for many years. Now, to meet the increasing demands for binders that comply with the most stringent workplace health requirements, Synthomer has developed new Lipaton SB 60B11, a low-VOC and low-odour XSBR binder offering even better adhesion and elasticity.

Synthomer binders for cementitious waterproofing systems

Cementitious waterproofing systems are used to protect mineral-based substrates for interior and exterior applications, for example water reservoirs, swimming pools and balconies. Our dispersions build a polymer matrix in the membrane to form a very dense, elastomeric barrier to liquids after curing. The cementitious waterproofing membrane maintains its flexibility under permanent immersion in water and when exposed to a wide variety of weather conditions. Plextol D 324 is ideal for applications requiring very good low temperature flexibility. Synthomer offers a broad range of dispersions for two-pack (2C) cementitious waterproofing systems based on XSBR (Lipaton), styrene acylic (Revacryl) and pure acrylic (Plextol) dispersions. These can be tailored to meet your specific requirements.

  • Comprehensive product range for liquid applied and cementitious waterproofing systems.
  • Formaldehyde-free and APEO-free systems.
  • Excellent durability.
  • Products optimised for interior and exterior applications.
