When it comes to protecting your home from the elements, selecting the right waterproofing product is crucial. Onduline offers a range of high-quality solutions designed to keep your home dry and secure. In this comprehensive guide, we'll compare four of Onduline's leading waterproofing products to help you make an informed decision.

Onduline Onduklaro

Onduklaro is a single-component polyurethane waterproof coating specially developed for long-term water immersion projects. It is made of isocyanate and polyether polyol as the main raw materials, with a variety of additives, fillers, and other reactive polymerization processes. After the material is constructed, contact with moisture in the air triggers the sealing of the curing agent in the system to solidify and form a film.

Product Features

  • Environmental protection, safe, and reliable
  • Excellent corrosion resistance
  • Excellent physical properties
  • High tensile strength, high elongation, and strong resistance to expansion and cracking of the base layer

Recommended Applications and Uses

ONDUKLARO Waterproofing Coating for Drinking Water


Onduklaro is versatile and can be used in a variety of applications, such as waterproofing and protecting domestic water transmission and distribution equipment, long-term flooded underground projects, bathrooms, balconies, and non-exposed roof projects. It is especially suitable for projects that require high water quality, such as swimming pools, pools, and canals.

For more detailed application instructions and technical specifications of Onduklaro, please refer to the technical data sheet.

Onduline Onducrete


Onducrete is a capillary crystalline cement-based waterproofing material made of silicate cement, quartz sand, and chemical substances. It penetrates the internal capillary channels of concrete and reacts with free lime and water molecules to form an insoluble water crystallization that fills pores and gaps and permanently seals the concrete.

Product Features:

  • Suitable for wet construction
  • Can naturally heal concrete cracks below 0.4mm
  • Prevents corrosion of reinforcing steel
  • Protects the concrete structure from wastewater, seawater, chemicals, and solvents
  • Reinforces concrete strength by eliminating cracks due to its unique permeability
  • No protective layer is needed after construction
  • Non-toxic and harmless material, can be used for drink water waterproofing
  • Easy to construct and no construction joint is needed


  • Can be applied on the surface of both positive and negative side of concrete structure
  • Suitable for damp substrates
  • Self-repairing material which can fix tiny cracks smaller than 0.4mm
  • Protects structural steel from corrosion for a long time
  • Strengthens the concrete structure and protects it from damage due to freeze-thaw cycles
  • Can be used to protect concrete from wastewater, seawater, and chemical corrosion
  • No protective layer is needed as it is an osmosis material

Recommended Use:

Onducrete is recommended for water proofing and anti-seepage treatment for swimming pools, drinking water pools, sewage tanks, marine aquariums, dams, reservoirs, and more. It is also suitable for waterproofing and seepage prevention in water immersion environments such as basements, underground water channels, elevator wells, balconies, toilets, bridges, tunnels, stadiums, nuclear power plants, military facilities, municipal engineering, and pile head treatment.

ONDUCRETE Waterpoofing Coating

Packaging and Usage Recommendations

Each bucket contains 25 kg of product. For a coating with a thickness of 1.0mm, we recommend using approximately 1.5 kg per square meter.

For installation instructions and technical details, please refer to the Onducrete technical data sheet.
