Comparative Guide in Choosing the Right Waterproofing Solution

1. ONDUKLARO Waterproofing Coating for Drinking Water

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 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.

2. ONDUCOAT PU Waterproofing Coating

ONDUCOAT PU is a single-component, elastic, water-resistant, leak-proof coating paint made from polyurethane. It can be applied on dry or damp surfaces and has the following advantages:

• Environmentally friendly waterproof coating
• Long-lasting
• Robust product
• Strong adhesion
• Easy application

Recommended Applications and Uses

Onducoat PU is suitable for a variety of applications, including non-exposed roofs, underground structures, indoor bathrooms, kitchens, and non-potable water constructions. It is recommended for use in podium slabs, lift pits, tunnel and subway structures, R.C. retaining walls and gutters, R.C. roofs, water features, and more.

Advantages

Onducoat PU has a number of advantages, including:

• Resistance to hydrostatic pressure
• Crack bridging properties
• Elasticity and flexibility
• Seamless application
• Good adhesion
• Can be applied by brush, broom or roller

Packaging and Coverage

Onducoat PU is available in 25kg/pail. Under normal conditions, the coverage rate for Onducoat PU is 1.3 - 1.5kg/m2 per coat. For more technical and installation data about Onducoat PU, please refer to the technical data sheet.

3. ONDUCOAT CE Waterproofing Coating

ONDUCOAT CE is a waterproofing coating made from elastic cement and modified polymer. It consists of two components: acrylate emulsion and special cement. It is an ideal solution for areas exposed to moisture, and has the following advantages:

• Excellent water impermeability
• Environmentally friendly
• Good weather resistance
• Strong adhesion
• Superior elasticity

Onducoat CE is a 2-part high polymer flexible cementitious waterproofing coating consisting of selected Portland cement, polymer latex, and proprietary additives. When applied to concrete, it provides an excellent barrier that is impervious to water.

Advantages

Onducoat CE has a number of advantages, including:

• Pre-batched components
• Non-toxic
• High flexibility
• Good adhesion
• Resistance to hydrostatic pressure
• Easy application by brush, broom or roller
• Environmentally friendly
• Excellent durability

Packaging and Coverage

Onducoat CE comes in two parts:

• Part A (Liquid) - 20kg/pail
• Part B (Powder) - 30kg/bag

The recommended ratio for mixing the liquid, and cement is 1:5.1:. Under normal conditions, the coverage rate for Onducoat CE is 1.3 - 1.7 kg/m² per coat. A minimum of 2 coats is required. An additional coat may be necessary for areas subject to extreme water ingress.

For more information about the installation process and technical specifications, please refer to the Onducoat CE technical data sheet.

4. ONDUCRETE Waterpoofing Coating

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

Recommended Applications and Uses

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.

Advantages:

• 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

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.
