Admixtures for Concrete

At Fospak (Pvt) Ltd., we understand that concrete is the backbone of modern construction, but its strength, durability, and performance can vary greatly depending on the materials and techniques used. That’s why we offer a specialized range of admixtures for concrete, designed to improve workability, setting time, strength, and long-term durability.

Whether you’re working on a high-rise tower, highway, dam, or residential structure, our admixtures are formulated to deliver consistent, high-performance results in all types of environments.

Why Use Concrete Admixtures?

Concrete admixtures are additives mixed into the concrete during the batching process to modify its properties. At Fospak, we offer a complete line of admixtures to meet specific construction needs, including:

Water-reducing admixtures
Set-retarding admixtures
Accelerators
Air-entraining agents
Plasticizers and superplasticizers
Shrinkage-reducing admixtures

These solutions allow for better placement, reduced cracking, and enhanced resistance to aggressive environments, especially when dealing with waterproofing concrete slabs or structures exposed to harsh conditions.

Enhancing Durability and Waterproofing

In large-scale concrete work, especially in basements, rooftops, and exposed slabs, waterproofing is a critical concern. Fospak’s admixtures work in synergy with concrete curing compounds and external waterproofing systems to deliver stronger, water-resistant structures. When used alongside our PU sealant or Tar Epoxy Coating, our admixtures contribute to a full-spectrum defense against water ingress, corrosion, and surface deterioration.

Our waterproofing admixtures are particularly useful for underground structures, water tanks, and foundations where moisture poses a long-term threat. Combined with PU sealants, they create a seamless protection system for critical areas.

Complete System Integration

At Fospak, we don’t just sell admixtures, we offer a full solution. Our admixtures are designed to integrate with other Fospak products like:

Concrete curing compounds to reduce surface cracking and moisture loss
Tar Epoxy Coating for corrosion protection in marine or industrial environments
PU Sealant for flexible, chemical-resistant joint sealing
Surface and subsurface waterproofing systems for waterproofing concrete slabs

This systemized approach ensures that each product complements the next, reducing the chances of failure and maximizing service life.

Quality Meets Affordability

All our admixtures are manufactured using high-quality imported raw materials and conform to international standards like ASTM, BS, and ACI. Despite the rising bitumen price in Pakistan and volatility in material costs, Fospak continues to offer market competitive pricing by optimizing production and supply chains, without compromising product quality.

Technical Support You Can Count On

Every construction project is unique. That’s why our technical team is always ready to help you choose the right admixture based on your site conditions, concrete mix design, and project timeline. From dosing advice to on-site trials, we’re committed to ensuring your concrete performs at its best.

Choose Fospak’s Admixtures for Concrete – because the foundation of quality construction starts with what goes into your mix.
