Expansion Joints cracking?

Janerol is constantly being asked if there is a way to cheaply repair expansion joints without the need for shock cord or rubberised products. Normal cement based products tend to crack and fall out but if you use the Janerol Epoxy Floor Repair you will find it will last a whole lot longer. Ram pack the joint to about 20-25mm from the top and just pour the resin into the joint. Allow it to puddle over the joint to compensate for any shrinkage, no trowelling necessary. Leave to cure and the job is done. the resin will bond to the sides of the joint and filter down into the "pack"to provide a virtually permanent plug.
