Yes it is and it's called CadWeld.  Their "OneShot" products are awesome.
Go to erico.com click on the Cadweld button and then select the type of joint (wire to ground rod for example) and then one specifys the rod size and wire size and you're left with a mold number.  Then call up you local industrial electrical supply house (not Home Depot) and place the special order.  I have to order a box of 12 minimum.  Also Hargar has a similar product called UniShots that I believe can be ordered individually.  Go to hargar.com to find their info.  My cost has been about $5.50 each and are permanent, weatherproof, and maintenance free (All you clamp guys regularly re-tighten all your clamps as they loosen due to climatic temp changes, don't you?).  They are, pardon the pun, "The Bomb".  Phil  KB9CRY
