What type of glue did you use? Might be the best place to start. Can you not fill the gaps with home made filler from sawdust and titebond? Just thinking outloud....

Hypo needle and vingar will loosen up the glue fill needle and inject into the slit. Let set and you may have to do this several times. I have done this on old furinture so it does work

Hello Clocks 1, if you used Ca Glue on your project this might help Ken Dolph made this posting a while back.

Default CA glue
We sell CA specifically for Corian.

Most CAs will work well however most people do not know the rules.

Here they are:

Joints must be tight - CA is an anarobic adhesive, it will not bond in the presence of air.

It requires 35% or higher humidity at the joint at the time of bonding. If it does not get the hydrogen it needs the joint will not be waterproof and will turn brittle with time. Breathing heavily on the surfaces prior to assembly is usually enough, or wipe with a damp cloth.

It hates acid at bonding time. If you wish to bond Wood you must rub the joining surfaces with baking soda first. This will produce a bond like no other in wood.

Polymers continue to grow for 24 hours. Tapping or any sudden impact will stop the process at whatever level it has reached. Do not test your joint for 24 hours.

Wicking the adhesive into a tight joint is almost always the best way to go. Thickened CA has a filler which makes it less strong.

Nitro methane is the best thing to use to pop a joint. Little else will effect it after curing. Nitro methane is available as a 30% mix as fuel for model airplanes. Only use clear fuel. Apply some to joint and tap untill the joint popps.

I have an installation, with 1/4" butt joints, in Corian, half under water, in the California desert, that flexes every day for 14 years. No failure.

I hope this helps
