Expansion Joints

Expansion Joints are joints in concrete or tarmac paving areas such as airfield hard-standings, petrol stations and car parks. The joints are designed to allow the tarmac or concrete to accommodate thermal expansion and contraction without cracking. In order to prevent the joints filling with debris or water joint sealants are installed. ALH Systems have a range of products to fulfil this need.
