Concrete expansion joints explained Hanson UK

Tips for placing concrete expansion joints Place joints around 30 times the slab thickness apart. So, for a slab which is 100mm thick, the joints should be placed around 3,000mm (3 metres) apart. Make sure joints are cut deep enough: they need to be at least a quarter of the thickness of the slab.

Expansion Joint in Concrete – Types and Characteristics ...

Expansion joints are placed in concrete to prevent expansive cracks formed due to temperature change. Concrete undergoes expansion due to high temperature when in a confined boundary which leads to cracks. Expansion joints are provided in slabs, pavements, buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.

Concrete expansion joints explained Hanson UK

Joints are most effective when the aspect ratio of the slab is kept to 1:1, for example 5m x 5m if the slab is a narrower than it is long it is possible to increase this to a maximum aspect ratio of 1.5 for example 2m x 3m, don’t leave the placing of concrete expansion joints to chance and enlist the services of a structural engineer if several are required.

What Are Concrete Expansion Joints? Do You Need Them?

Joints are used in areas where two slabs of concrete meet, when a slab meets another concrete structure like a wall or when a span of concrete is overly long. For example, a 100 ft. concrete sidewalk wouldn’t be poured in one long slab. You’d get lots of cracks. Rather, we cut expansion joints which breaks the sidewalk into smaller pieces. These smaller slabs of concrete can move much ...

22/06/2020  The Purpose of Joints in Concrete Slabs. As concrete moves, if it is tied to another structure or even to itself, we get what's called restraint, which causes tensile forces and invariably leads to cracking. Restraint simply means that the concrete element (whether it's a slab or a wall or a foundation) is not being allowed to freely shrink as it dries or to expand and contract with ...
