Sikacem 520 Waterproofer – High-Performance Concrete & Mortar Waterproofing Admixture | CETECH Ghana

Sikacem 520 Waterproofer is a waterproofing admixture for concrete and mortar that makes structures more water-resistant, chemically durable, and longer-lasting. It is designed for mass waterproofing of foundations, tanks, and similar concrete structures, and is especially effective in Ghana’s humid and water-exposed environments.

Available from CETECH Ghana both online and in physical stores, Sikacem 520 Waterproofer gives contractors and builders a professional, field-proven solution for waterproof concrete, mortar, plaster, and render.

What Is Sikacem 520 Waterproofer

SikaChem 520 Waterproofer is a liquid mass repellent for concrete used as an integral waterproofing admixture. It is mixed directly into concrete or mortar to reduce water penetration and increase durability.

It is specially formulated to:

• Enhance the durability of construction materials
• Improve water resistance of concrete and mortar
• Increase chemical resistance against aggressive water types
• Protect reinforced and unreinforced concrete structures

It is suitable for:

• All types of mortars
• Reinforced concrete
• Unreinforced concrete
• Plasters
• Renders

For buyers searching for waterproofing, concrete waterproofer, plastering waterproofer, or best waterproofer in Ghana, this product is built specifically for those needs.

Product Identity and Technical Classification

Sikacem 520 Waterproofer belongs to the class of integral waterproofing admixtures. This means it works throughout the entire concrete or mortar mass, not only on the surface.

Technical identity:

• Product name: SikaChem 520 Waterproofer
• Type: Waterproofing admixture for concrete and mortar
• Form: Liquid
• Function: Liquid mass repellent for concrete
• Application: Added during mixing stage
• Use category: Professional use only

Unlike surface coatings, it creates internal water resistance inside the cement matrix itself.

Core Performance Functions

Sikacem 520 Waterproofer improves performance in three primary ways.

Water Resistance Improvement

• Reduces capillary water absorption
• Limits water penetration through concrete and mortar
• Improves watertightness of structures
• Supports leak prevention in mass concrete

Durability Enhancement

• Enhances long-term durability
• Reduces moisture-related deterioration
• Protects embedded steel reinforcement indirectly by limiting water ingress
• Strengthens resistance to damp environments

Chemical Resistance Upgrade

It significantly improves chemical resistance against:

• Sea water
• Industrial water
• Selenitous water
• Pure water exposure

This makes it suitable for harsh Ghanaian site conditions, including coastal and industrial zones.

Material Compatibility and Composition Behavior

Sikacem 520 Waterproofer is formulated to be compatible with:

• Cement mortars
• Concrete mixes
• Reinforced concrete
• Unreinforced concrete
• Plaster mixes
• Render mixes

As a liquid admixture, it disperses evenly when added with mixing water. Inside the mix, it modifies the pore structure and reduces continuous capillary channels that normally allow water to travel through hardened concrete.

Resulting material effects include:

• Reduced permeability
• Tighter pore structure
• Improved internal water repellency
• Better resistance to aggressive water chemistry

Primary Application Field

The defined application field is mass water repellent concrete structures.

Typical uses include:

• Foundations
• Concrete tanks
• Water retaining structures
• Substructures
• Basements
• Similar heavy concrete elements

It is specifically designed to withstand attacks from:

• Selenite waters
• Sea waters
• Industrial waters
• Pure waters

For Ghana projects near the coast, wetlands, or industrial discharge zones, this resistance is a major selection advantage.

Use Instructions and Correct Dosage

Correct dosage is critical for performance and compliance.

Official Use Instructions

• Add to the concrete mixer at the same time as water
• Ensure proper mixing for uniform distribution

Recommended Dosage

• 0.7–2.0% of the cement weight
• Equivalent to 0.7 kg to 2 kg per 100 kg of cement

Dosage should be selected based on:

• Exposure severity
• Structure type
• Engineering specification
• Required waterproofing level

CETECH Ghana provides technical support on mix ratios and application guidance for contractors and site engineers.

Professional Use and Safety Requirements

This product is specified for professional use only.

Important safety notes:

• Safety datasheet available on request
• May contain allergenic agents
• Always consult the most recent product instructions before use

Professional handling ensures:

• Correct dosage control
• Proper mixing procedure
• Compliance with engineering specs
• Safe storage and handling

What Other Ghanaians Are Searching For About Waterproofers

Search behavior in Ghana shows strong demand for multiple waterproofing use cases. Sikacem 520 Waterproofer directly addresses these needs.

Advantages Over Surface Waterproofing Methods

There are two main waterproofing strategies:

• Surface waterproofing coatings
• Integral waterproofing admixtures

Sikacem 520 Waterproofer is an integral admixture, which provides several advantages.

Integral Waterproofing Advantages

• Protection throughout the full concrete thickness
• Not dependent on surface film integrity
• Cannot peel or flake off
• Continues working even if surface is scratched
• More durable in buried or submerged structures

Surface coatings remain useful, but for mass concrete and mortar waterproofing, integral admixtures are often the preferred engineering choice.

Comparison With Other Waterproofing Options in Ghana

Other waterproofing options in the Ghana market include:

• Cementitious waterproof coatings
• Bituminous coatings
• Membrane sheets
• Acrylic waterproof paints
• Other waterproofing admixtures

When compared to many alternatives, Sikacem 520 Waterproofer stands out for:

• Internal mass waterproofing action
• Chemical resistance to aggressive waters
• Compatibility with many mix types
• Defined dosage framework
• Professional technical backing

Contractors often combine integral waterproofers with surface systems for critical structures.
