Expansion joint filler board Features
The latest compressible filler board is based on polymers, and is a Cross Linked Closed Cell Polymer, also known as Compressible Expansion Joint Filler Board or Micro Cellular Filler Board. In India it is also known as HD100 joint filler boards. The 100 refers to the density of the filler sheets, which is 100Kg per CuMtr.
Expansion joint filler HD100 board is flexible and has high compression-recovery, therefore it’s suitable for application at places which require readily compressible low load transfer joint filler boards. This filler board is non-tainting and therefore suitable for use in potable water retaining and water excluding structures.
Salient features of these boards are:
–Resilient – 95% recovery after deflection (compression), as it is one of best feature for any expansion joint filler board desired
–Weathering Test – Joint filler board is resilient and does not distort under low load transfer from wet concrete
–Closed cell structure – HD100 joint filler board extremely low water absorption thus non deteriorating and durable
–Bitumen free – Opposite to bituminous filler board it is non-staining
–Chemically Resistant – As any EJF board needs to be inert to most dilute acids, resistant to oil and hydrocarbons and it is very suitable for EJF applications.
–Hygienic – Rot proof and bacteria resistant
–Simplicity – Unlike the bituminous filler board it is very easy to handle and install it.
–Temperature – Accepts temperature cycle with minimal load transfer
