EZ Shim Heavy Duty Shims - Plastic - 7.9 Inch Review

More expensive than wood gaskets, they are excellent for leveling and sealing, easy to trim, will not splinter, and are even weather and rot resistant for use in wet environments. .

Very happy with the plastic gaskets. I used them to line an outdoor kitchen. These pucks are amazing! They had no problem slipping under a solid base (summer kitchen floor). I will also be using them to line my spa. They are very strong and seem to be holding up. You can't go wrong with this.

Very strong and hard enough not to dent or flatten. It looks like it can handle areas of high humidity and extreme outdoor weather. It's very thin on one side, so you can handle even the slightest wobble. The thickest side is probably only about 1/4", so it probably won't work on a severely uneven surface unless you want to glue multiple epoxies together.
