Expansion Joint Filler
Expansion joint filler is a material that is used to fill the gap or space between two structures, such as concrete slabs, walls, or floors, to allow for movement due to thermal expansion or contraction. The filler material is placed in the joint to maintain the structural integrity of the joint, provide a smooth surface, and prevent water and debris from entering the joint. There are several types of expansion joint fillers, including:
- Preformed Compressible Filler: These are made from a compressible material, such as cork or neoprene, and are placed in the joint before the concrete is poured.
- Preformed Non-compressible Filler: These are made from a non-compressible material, such as wood or metal, and are placed in the joint before the concrete is poured.
- Field-installed Compressible Filler: These are made from a compressible material, such as cork or neoprene, and are placed in the joint after the concrete has been poured.
- Field-installed Non-compressible Filler: These are made from a non-compressible material, such as epoxy or polyurethane, and are placed in the joint after the concrete has been poured.
- Elastomeric Filler: These are made from a elastomeric material, such as silicone or polyurethane, and are placed in the joint after the concrete has been poured. They provide flexibility and high movement capabilities.
