Concrete expansion joints
 

Hi all,

I've got several expansion joints in my concrete drive that have now
rotted away. I don't want to fill the gaps in with wood, and I was
wondering if there is any other material that can be used.
I wondered about tar or a resin type filler, but I'm not sure what I'm
looking for:(

Any suggestions?

TIA

The correct way to form construction joints is to use a compressible
bitumen-impregnated board, such as Flexcell, up to 25mm from the top surface and
then fill the gap with polysulphide mastic such as Thioflex One. These
materials are available from builders merchants but you may need to order.

Hi,

Tar seems to work for all the cracks in the roads that are patched up.
It might be that the wood in the joints was used as shuttering when
the drive was laid.

cheers,
