Incredible gave good advice! Take it out on the patio on a nice day! Make sure the cement is dry. You don't need to fill it completely. About three to four inches of h2o will usually be sufficient. See where the cement is getting wet, and look above that spot on the kayak. Find the leaks. Some people put the yak a little above the cement, suspending the yak on two sturdy boxes. Mark the leaks with a crayola, or marker. You need a heat gun and a plastic repair (weld!) rod in the same color as your yak. Most manufacturers will send you one. Ocean Kayaks sent mine free! With instructions! Seak the leaks and you're good to go. The number one cause of kayak leaks is the scupper cart! Yaks can't take the leveraged stress these carts inflict on the scuppers when you pull the yak over bumps and sand! Good luck! Piranha
