Regardless of the frequency of your pool repair and maintenance routines, in-ground pools will eventually develop cracks. This is most especially true for those pools that have been in use for more than 15 years. Many pool owners immediately worry when they see cracks in their in-ground pools. However, you don’t have to because there are easy and permanent repairs for the cracks in your in-ground pools.
Where do cracks often develop?
Basically, cracks can develop on the surface of your in-ground pool or in the corners. Those that are visible on the surface, often on the top step or anywhere close to the surface, are small hairline cracks. You do not have to really worry about these as these are very common among in-ground pools.
On the other hand, cracks that develop in the corners run deeper and are usually longer. They are commonly seen where the spa wall joins your swimming pool wall, behind the tile line or in the beam of your in-ground pool.
Type of pool repair for in-ground pool cracks
The types of pool crack repair depend on the particular type of crack and the permanence of the repair. According to experts, the more difficult the repair you chose to implement on the crack, the longer and more permanent it will be.
- Easy repair
An easy repair is applicable to small, hairline cracks on the surface of your in-ground pool plaster. The first step for this type of repair is to widen the cracks using a screwdriver. You also want to scrape the screwdriver down the crack to remove any debris that has been stuck in the crack. Keep in mind that the crack needs to be a little bit wider and empty inside.
After this, you will need to mix some pool putty. This is available in many pool supplies store or at the nearest home depot or hardware store from your location. Strictly follow the instructions for mixing the pool putty. Roll it into a long rope shape, making sure it is thick enough to fill and cover the crack. Push the putty into the crack and make sure it is entirely filled. You can use your hands to smooth down the putty and remove the excess.
- Moderate pool repair
A moderately difficult pool crack repair obviously requires more effort and time than the easy type of repair. What is good about this type of repair is that it has more permanence and allows the repair to last longer. Plus, it will be easy for you to match the color of your pool plaster.
- The first step for this particular type of repair is to drain your in-ground Note that it is not highly advisable to do this after heavy rains as the water might cause the still loose soil to collapse and be drained. Also, keep in mind that when you are draining your swimming pool, make sure the water will not go underneath your swimming pool to avoid more severe problems.
- After draining your swimming pool, you need to pull out the hydrostatic plugs first for safety measures. You will find your pool’s hydrostatic plugs plastered into your pool’s floor. The plug is secured by plaster so you will need to remove the plaster first before you can reach the plug. Use pliers to grab, pull and un-thread the plug. Do this for at least 2 of the hydrostatic
- Use a grinder to widen the crack. If the crack is too small, you can opt to use a drill with a masonry drill bit. You do not need to buy these power tools if you do not have them. You can opt to borrow from a friend or neighbor or you can also rent them from nearby rental shops. Before using these power tools, make sure you wear safety gear – eye and ear protection, gloves, boots and long pants, and a dust mask as it could get dusty. Keep in mind that a grinder is very dangerous so you need to handle it with utmost care. Hold it firmly and properly so it won’t get near your finger or leg.
- While widening the crack, you also want to create a dovetail on the crack. This refers to cutting the crack at an angle to improve the success of the repair. The best way to do this is to create a reverse V shape at the end of the crack into the plaster. Make sure the dovetail reaches into the concrete beneath the plaster. This way, the plaster will be able to hold the patching material more firmly.
- Clean the cracks using a garden hose to make sure there are no dust, debris and loose materials left inside and around the cracks. They need to be clean inside and outside of the patching material to stick more easily.
- Mix a pool plaster mix that you can get from any home depot, hardware store or pool supplies store. If the crack is more than one inch deep, fill it with hydraulic cement first leaving the top half inch to be filled with the pool plaster mix. The crack should be moist before filling with the plaster mix. You can opt to use a type of bonding additive to ensure the plaster will stick more easily and much longer into the crack.
- Keep the area moist at all times after filling it with the plaster mix. This is to ensure that the mix will dry at a slow pace rather than too quickly. To do this, you can lay a wet towel over the area or cover it with plastic that has holes every few inches.
- Extreme pool repair for cracks
This type of repair is made for cracks that run across the pool floor and along the wall. What makes this different from other types of repairs is the use of staples to hold the pool wall or floor together. This makes the repair more effective and last longer.
To do this, you will need to make horizontal cuts that are perpendicular to the crack every few feet along the length of the crack. Drill holes at each side of the horizontal cuts where you will place the ends of a steel or carbon fiber staple. Epoxy it in place. Once the staples are in place, you can work to fill the cracks with plaster mix or you can also opt to re-plaster or repaint your entire swimming pool.
Make sure you work with a professional pool repair and technician to confirm the best and most suitable type of repair for your swimming pool.
