San Diego Deck O Seal or pool expansion joint is a rubbery material separating the pool coping and deck. It’s purpose it to prevent against damage when the swimming pool encounters expansion and contraction. This happens as the pool warms up and cools down. Without the Deck O Seal, there is a possibility of damage. If the pool expands and puts pressure on the, it may crack one of the surfaces or structure. The Deck O Seal material also helps prevent moisture from getting under the pool deck. When this happens, the soil can erode causing the deck to sink or crack.

San Diego deck O Seal | pool expansion joint explained
Deck O Seal and pool expansion joint comes in a variety of colors. The most common colors are grey and tan. The others are white and black. They also have custom colors but, are seldom used. The grey and tan are most common because most concrete or stone pool decks are similar. The Deck O Seal and pool expansion joint last on average a few years. The life expectancy is based on the movement of the surfaces and the materials bond. We always make sure to prepare everything properly to ensure the longest life possible. When done incorrectly you may see low points that look like mini sink holes. You may also encounter separation from the surface due to bad prep work.
San Diego deck O Seal installation process
The Deck O Seal installation process consists of a few things. One is to thoroughly remove all of the old material from the deck and pool coping. The next step is to pack the opened area with either sand or foam. That allows the material to not sink in when installing. Once that is done, we start to mix the two part product. This needs to be done correctly to ensure that the material will actualy set up and cure. We then take that from the gallon can to a pour container and start installing the product. This is a self leving pool material that can be very difficult to clean if spilled. The final step is to lightly sand the surface of the Deck O Seal. This is what gives it a natural appearance. If you did not add the sand, it would look like a big rubber band around your swimming pool. The Deck O Seal needs to set up overnight or longer depending on the temperature. You can not use the pool or touch the material. If you did, the material would stick to anything it comes into contact with. You will never get it off. That is the same for your pool deck. If it gets on your pool deck, it will be a nightmare to remove often causing some short term dis-coloration.
