Modern tunnelling and mining projects require concrete that delivers fast strength development, durability, and excellent workability under demanding conditions. In weak rock environments, concrete segments act as immediate structural linings for fully excavated tunnel sections. These precast tunnel segments must achieve high early strength, dimensional precision and long-term durability to ensure safety and stability in underground construction.
Sika’s advanced admixture technologies make it possible to produce high-performance concretes that meet these requirements providing excellent pumpability, flow, compaction and early strength development, followed by low permeability and long-lasting durability.
Advantages of Sika Admixtures for Fair-Faced Concrete
- Delivers smooth, consistent finishes that meet high architectural standards
- Enhances workability and flow to achieve superior surface quality, even in complex formwork
- Supports a wide range of design possibilities through pigmentation, texture and finish control
- Ensures durable, low-maintenance concrete that resists mechanical damage and weathering
- Eliminates the need for surface coatings or paints, reducing long-term maintenance costs
- Provides a cost-effective solution compared with other façade or cladding systems
- Backed by Sika’s century of experience in concrete formulation and performance optimisation
How to Achieve Fair-Faced Concrete
UNDERSTANDING THE DESIGNERS VISION IS VITAL
To enable the successful realisation of the design Sika needs to collaborate with the designer at the earliest opportunity to ensure good communication and understanding.
PROPER FORMULATION OF THE CONCRETE MIX DESIGN
It is key to achieving fair-faced concrete of the required quality. Sika admixture solutions are optimised providing superior finishes and durability.
SURFACE FINISHING
There are many different types of surface finish that can be achieved including formed concrete, polished concrete, exposed aggregate finishes and more.
ON-SITE SUPPORT
Sika technical representatives support the owner, designer and contractor on their projects from the initial design through to completion.
