Accounting for temperature changes on concrete

Concrete is considered to be one of the most durable building materials in the world, and has been used in the construction industry for thousands of years. Roman buildings like the Colosseum were built from concrete, and have survived through the centuries because of the outstanding properties it offers. Concrete has become more widely used in construction than any other material.

The strength and durability of the material is a major advantage, but it is important to consider how it will react in various temperatures. When it gets hot or the moisture content changes, concrete will expand. This is why we see expansion joints on concrete bridges, buildings and surfaces. These joints are necessary to prevent issues when expansion occurs, but they also create a potential weakness in the material that needs to be accounted for. In colder temperatures the concrete can contract slightly too, making the potential weak spot even wider. As a result it is important to ensure that each joint is sealed and monitored.

Joints in concrete must be sealed in a way that will allow the material to expand when it gets warmer and contract when the temperature drops substantially. The materials used to fill and seal the joints needs to be compressible to prevent bulging when it gets warm. They also need to be stretchable so they can fill widening gaps in the winter when contraction occurs. It is vital the correct material is used to give each joint the necessary protection it needs.

At Churchill Concrete Technology we have a great understanding of how concrete behaves and can provide first rate joint sealing and waterproofing services to protect surfaces and structures. In order to maximise the quality of each service, we take the time to inspect the surface and the environment, and can carry out a full survey and testing. This knowledge will help us to devise the right measures to seal and waterproof the joints.

With us you can have complete confidence we will offer a sustainable solution that will protect the concrete for a long time. If you would like advice or further information please feel free to contact a member of our team.
