Reasons for expansion joint sealing
We mentioned above some broad reasons for requesting expansion joint sealing, so let’s look at those in a bit more detail. Firstly, health and safety issues.
One of the key reasons for providing expansion joint sealing to our clients is to reduce risks associated with health and safety. As the concrete slab or floor cures and contracts, the expansion joint may get wider and create a risk to those walking on the surface. This is particular risk where the area is used by the public and may mean that people are walking in the area wearing high heeled shoes or sandals which may get stuck in the gap or clip the edge causing people to trip or twist their ankle. Public safety is obviously a key factor so hazards such as these must be avoided.
Secondly expansion joints may be sealed to reduce the damage that can occur to the edges of the joint with wear and tear and repeated pressure from vehicles or heavy traffic. If the edges of the joint starts to break down it can start to cause damage to wheels of cars or impact other users. It may also start to affect the integrity of the concrete slab.
Thirdly in areas where chemicals are used there can be a risk that the chemicals may infiltrate the concrete and cause deterioration in the structure or contamination.
How does expansion joint sealing work?
Expansion joints are obviously used in construction all the time to allow space for the concrete to expand and contract according to the temperature and moisture levels, so what happens when you seal it? National Drilling Services has carried out research and tested various products to find the best sealants to avoid the risks highlighted above, but still enable the concrete to expand and contract.
