Sandberg provides specialist advice at the design stage which can prevent many problems occurring during construction. New specifications can be prepared or existing ones reviewed to optimise both durability and constructability.
Our range of services includes:
- Durability assessments for new structures
- Advice on performance testing for concrete and its constituent materials
- Production of materials and concrete specifications
- Advice on all aspects of concrete performance, based on the most recent developments in technology
Construction Support
Sandberg offers a range of services to contractors to assist them in achieving their objectives. Whilst based on the latest technology, our approach is focused on the practical application of technology during construction.
- Advice on achieving performance requirements
- Materials selection
- Concrete mix design development
- Advice on appropriate construction techniques
- Site monitoring
Service Life Estimation of Concrete
Concrete That Lasts: More Than Just Strength — It’s About Time
We offer technical support in concrete specification and service life estimation to help meet project performance and durability requirements:
New Concrete Structures
For new structures, we offer:
- Specification in accordance with BS 8500 and EN 206
- Concrete mix designs matched to UK exposure classes (e.g., XC, XD, XS)
- Service life design options for 50, 75, or 100+ years
- Assistance in avoiding overdesign while ensuring long-term durability
Existing Concrete Structures
For existing structures:
We can develop and implement a sampling and testing program tailored to the structure, which may include:
- Chloride Profiling
- Carbonation Depth Measurement
- Concrete Core Sampling and Analysis
- Cover Depth Surveys
- Chloride migration and diffusion testing
Service life modelling is carried out using the fib Bulletin 34 approach to provide an estimate of remaining service life. This helps inform decisions on repair, maintenance, or replacement strategies.
Our services cover both initial concrete specification for new builds and the evaluation of existing structures to support asset management and maintenance planning.
Investigation
Should problems occur either during construction or at some subsequent time, Sandberg can help. We have extensive experience in diagnosing and solving concrete-related problems, including:
- Poor fresh concrete characteristics
- Low-strength concrete/failure to meet performance specifications
- Concrete deterioration and damage
- Failure in service
In the event of litigation, Sandberg can also provide expert technical advice and assistance:
- High-quality support in concrete technology
- UKAS-accredited laboratory facilities
- Provision of expert witnesses
