Concrete Repair
Introduction
Concrete repair has been the main core of our business since its inception back in 1995, originally concentrating on traditional repair techniques. Product and technique advancements have meant we have had to increase our knowledge and diversify our scope of operations so that we can provide a solution to any concrete failure problem.
There are numerous repair methods and in order to determine the best techniques and products a good understanding of the construction processes and the nature and cause of the failure is essential. South West Concrete Repairs Ltd are Investors in People and have an ongoing training programme which includes manufacturer product training, repair techniques and health & safety training so that our operatives keep ahead of changes within the industry.
Key Factors to be considered
In order to provide our clients with repair solutions that meet their needs the following factors must be considered before submitting detailed proposals.
- The design life or client requirement of longevity
- As a temporary or long term solution
- The need to restore structural strength
- To restore the structure back to existing profiles
- Elimination of corrosive conditions
- Provision of fire resistance
- Prevention of further deterioration
- For appearance only
Following investigation into the causes of the failure and an assessment of the clients needs and requirements, the best repair technique and most suitable products can be determined.
