Concrete expansion joints explained Hanson UK

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. For a 100mm slab, cut the joints at least 25mm deep.

10/01/2013  Construction joints are placed in a concrete slab to define the extent of the individual placements, generally in conformity with a predetermined joint layout. Construction joints must be designed in order to allow displacements between both sides of the slab but, at the same time, they have to transfer flexural stresses produced in the slab by external loads.

Concrete expansion joints explained Hanson UK

A concrete expansion joint – or control joint – is a gap which allows the concrete to expand and contract as/when the temperature changes. It forms a break between the concrete and other parts of a structure to allow movement without causing stress, which can lead to cracking. They should be used in large concrete slabs such as foundations and concrete driveways.

Construction Joints in Concrete Structures - Structural Guide

Providing construction joint in concrete limits the area to be concreted in a one pour. For example, when there is a large area to be concreted, we divide the area into several pours. It speeds up the construction work as part completion of work can proceed to concrete work. Further, a large area cannot be concreted within a day. It will take a long time and a huge volume of concrete could be ...

22/06/2020  But across construction joints or contraction joints in slabs that will have heavier loads, we need a way to keep the slabs vertically aligned as the traffic crosses. The problem is that if one side of the joint is deflecting under load, then the wheels will hit a slight rise on the other side of the joint and eventually the edges of the joints will break down. In those cases, when there's a ...

Construction Joint in Slabs The Structural World

13/02/2018  Construction joint is one of the types of joints in site construction that can be located on walls and slabs. The most popular usage of construction joint is on suspended slabs. Literally, it is defined as a longitudinal cut in the slab during the concrete pouring process. It is termination on slab during the concreting works. This is usually done in wide span areas of the slab being ...

Vertical construction joints in walls, beams and slabs will usually have been formed against a stop-end. Stop-ends should be located where the reinforcement is least dense; they should be well made, easily strikable, and fixed to avoid grout loss. A typical stop-end detail is shown in Figure 2. Most vertical construction joints do not require any surface treatment, plain smooth surfaces being ...

Joint Waterproofing - Sika

Due to the nature of concrete and reinforced concrete, structures are built divided into sections by forming joints, namely three types – construction joints, movement joints and connection joints. The key function of joint sealing is to minimize water ingress and create a secure waterproofing barrier. The seal must be capable of accommodating the anticipated joint opening and closing due to ...
