Fix Structural Cracks In A Concrete Pool With Staples
Make a horizontal cut on the crack. Drill a hole on both ends of the cut. Put a steel or carbon fiber staple to fuse both sides of the crack. This process is actually more complex than it seems. An experienced pool repair professional can help you ensure that structural cracks in your pool are completely fixed.
DIY repairs might be great for fixing surface cracks. Structural cracks, however, are best left for experts. Fixing them on your own might do more harm than good. Getting the best pool repair service in Sarasota will do wonders for your pool. Read one of our many clients testimonials.
Cracking Due To Rebound
Material that flys off or bounces of the rebar and existing concrete is often called Rebound It has a higher concentration of sand and less cement than the original mix, thus it is weaker than the original material. Contractors will often reuse this rebound material to save material and labor. They may use it on the bottom of the pool, in the step entry areas of the pool, or the seating benches or ledges in the pool thats below water.
This practice of poor workmanship may result in weakened areas or cracks at times. If you look closely you may see crack evidence in the entry step area of many pools. When the rebound caused cracks are at the entry step area, they do not always go through the entire shell, therefor there is no leak.
Delamination is another issue with rebound materials, for they do not always bond fully with other gunite or shotcrete that has been shot. The bonding problem relates to the fact that rebound material has less cement and more aggregate and sand.
Plastering A Swimming Pool
Daily contact with chemicals and exposure to outdoor elements can slowly dissolve the plaster coating in a concrete pool and cause it to chip in a process known as spalling. Although this does not pose a structural hazard, it is unsightly and can create jagged edges that harbor algae. You can repair spalling by patching, but it will recur. Eventually, youll need to replaster, usually within 7 to 10 years of the pools construction. A plasterer will first sandblast off the old plaster, to ensure that the new coat will adhere well.

Concrete Pool Crack Causes
Concrete pool cracks may be due to ground or foundation movements. The quality of your concrete structure is also essential to avoid cracks. If materials wear down or especially if they are not of good quality to begin with, they can be the source of cracks in your concrete pool.
To avoid the formation of these cracks, it is important to research the materials used during your pool installation and study the characteristics of the ground where the pool is located.
Transition Areas / Cut And Fill
Pools built on an area that has both cut and fill soil will incur more problems than ones built fully on cut or fill. The tendency on a cut and fill area, often called a transition area, is for the portion of the pool built on fill to settle. This unequal movement leads to cracking. Hill side homes have more cut and fill problems than those build on all cut or all fill.

Pool Repair: Is A Diy Good Enough
Pool crack repair underwater is not an impossible job. It is an option for homeowners who want to have an immediate though temporary fix. Theres nothing wrong with a DIY project as long as it is only for a short period until such time that licensed pool experts come in.
Rather than just plaster repair which we do not recommend, it is best that professional pool contractors are to handle the leak detection and proper repair the soonest time possible. Or else, youll be spending more money on major repairs down the line.
The above DIY projects are just temporary solutions. Do not be content with the outcome of your DIY project. Remember there are most probably bigger reasons why those cracks started.
Why Are Pool Cracks So Dangerous
Pool cracks are dangerous for a number of different reasons. First, they can damage your pools structural integrity. This can lead to leaks or a shift in your pools structure that result in more cracks. The cracks can also spread to the decking around the pool, causing damage there, too. These cracks can pose a danger to anyone using the pool. Someone could trip, a board in the deck could break when stepped on, or the pool water could leak into the surrounding area. That could actually cause structural damage to your house if the ground becomes so wet and soft that your homes foundation starts to sink.

Repairing Small Pool Cracks
If you see any very tiny cracks around your pool area, in the tile of the pool, or around your deck, the first thing you can do is take a small amount of clear silicon and fill in the crack. Make sure youre using silicon designed for outdoor use, not silicon thats rated for kitchen or bathrooms only.
For cracks that are a bit larger, you may first need to use a screwdriver to remove any little pieces of loose material inside the crack. Otherwise, your repairs will be attached to material thats not very stable. Its likely this patch wont hold for long. Now that youve removed any other damaged material, you want to fill in the crack with either silicon or pool putty . If the crack is wide enough that you can get a screwdriver head inside it, you likely need to go with the pool putty. Push it down into the crack as far as you can, then wipe off any excess. This patch can be applied while the pool is still full of water.
Its important that you deal with these small cracks as soon as you see them. Otherwise, its possible that water from your pool can get underneath your deck. This water can cause wooden decks to start to rot, which brings about many more problems.
What Is Pool Plaster
Concrete swimming pools are built with a concrete and reinforced steel shell about 30 to 45cm thick and are commonly lined with a white plaster to waterproof and finish the inside of the pool.
The plaster is usually a mixture of white cement and fine white limestone sand with a small amount of calcium to accelerate the drying process.
The plaster is white and the pool will look light blue when filled with water. Some people have a color additive mixed into the plaster to give the pool a deeper blue or a custom color.

Mirrored Or Reflective Cracking
Tile and plaster often mirrors a crack that is behind them i.e. if there is a crack in the bond beam, the tile may crack in the same area that the bond beam is cracked. The same is true with cracks in the plaster.
Cracks may also appear in areas where the concrete covering the rebar or piping is insufficient. When the rebar has insufficient cover, then there may be a pattern of cracks that reflects the rebar pattern. Over time rust my come out of these cracks and that can be a significant concern, for as the rebar rust it expands in volume up to four times its diameter. This expansion creates tremendous pressure on the concrete, causing spalling, cracks and damage.
Dont Put Off Swimming Pool Crack Repair
It may seem like a good idea to put off repairing a small crack, especially when you spot cracks in your pool at the end of the season. However, putting off a repair can prove disastrous.
Over the off-season, the effects of fluctuating temperatures and settling ground can expand the crack, leaving you with more severe damage when good weather comes and its time to open the pool again.
If the crack is in a spot where water leaks, it can cause water damage to your property, including your homes foundation if it is close to the pool. It could also damage any deck or patio structures around the pool. A slow, steady leak can also be detrimental to your plumbing system over time.

Why Do Pools Crack
Theres quite a few reasons a swimming pool can break, but a few of the top reasons for cracks are:
Pool Built on a Hillside Lot This is the No. 1 reason for cracks in swimming pools that we see. This is the predominant cause mostly because of our location in southern California. Living where we do, many of us are bound to live on or near hills thus, many of us build our swimming pools on or close to a hillside. Unfortunately, this doesnt bode well for the health and longevity of your pool due to something called slope creep. Its due to gravity! Slope creep refers to the gradual downhill movement of soil on a hill . This causes anything on top to eventually move with it, leading to tilting, leaning, and foundation/structural distress.
is where some of the hill is slowly moving with the pool With that moving of the hillside, the pool is tilting or moving or losing support and it is causing a crack.
Gunite Too Thin or Rebound Gunite Having too thin of gunite shot during the construction phase can lead to a pool that breaks easily. The right pool builder will make sure this doesnt happen. Rebound gunite is gunite that bounces back during placement. According to the experts, rebound gunite should always be thrown away. However, some pool contractors pack the rebound gunite back in and build some of your pool with it. A good pool contractor will NOT do this because rebound gunite is extremely weak and will damage the structural integrity of your swimming pool.
Pool Concrete Repair: How To Fix A Cracked Pool
Youll have a few options when it comes to fixing structural cracks in a concrete pool shell:
- Inject epoxy or polyurethane into the crack to seal it off
- Apply hydraulic cement over the crack
- Staple the crack closed with rebar staples
- Tear out and redo the damaged area of the pool
Injecting epoxy or polyurethane arent the best long-term solutions, but they might be the most affordable in the short-term. Applying hydraulic cement is similar to injecting epoxy in terms of durability. It can be a good temporary solution, but it doesnt address the root of the problem.
Stapling the crack can prevent further cracks and keep that area from opening up again. This can cost anywhere from $1,000 to $3,000 and up. Redoing the damaged section altogether can cost much more than stapling it, but the final cost will depend on your contractor and the extent of the work that needs to be done.

Patching A Vinyl Pool Liner
The lining of a vinyl pool can be torn easily, but small tearsless than 3 inches longcan also be repaired easily. In many cases, you can do it yourself rather than bring in a professional. Anything much longer than 3 inches may require replacing the entire liner. The most common way to repair a torn vinyl liner is to drain the pool to just below the tear markbeing careful not to completely empty the pool, unless under a professionals supervision. Then patch the liner, similar to the way you patch a bicycle inner tube.
To make the repair, it is important to have a piece of material that is identical to the original pool material. To prepare for eventual patching needs, ask the installer to give you an extra piece of liner when the pool is constructed. Some manufacturers make underwater patching kits. To use one of these kits, position the patch, then apply pressure from the center outward to squeeze out any water.

How To Search For Leaks
Before you can repair a leak, youve got to find it. Its often difficult to determine whether a drop in the pools water level is the result of a leak or normal evaporation. You can call in a professional leak detector to make the diagnosis, but first perform a bucket test yourself. Fill a bucket three-quarters full with water and mark the water line on the inside of the bucket also mark the water line on the wall of the pool.
Let the bucket float in the poolwith the handle removed for better stabilityfor two or three days, keeping swimmers away. If the water loss is due to evaporation, the water level in both the bucket and the pool will have gone down by the same amount if its due to a leak, the level of the pool will have dropped farther than the water in the bucket.

How Long Does Plaster Last In A Swimming Pool
Typically a plaster lined swimming pool will last 10 to 20 years depending on usage and how the pool has been looked after. Over time plaster will lose its clean, white appearance and build up a dullness and accumulate etches, pitting or stains. Most people realise and accept this is the normal aging of the pool surface but other pool owners want their pool to look great all the time so they choose to have the pool renovated more frequently. Hotels, apartments and other community properties will more frequently renovate their pools to uphold their high standards of maintenance and presentation.

Fixing Swimming Pool Cracks
Cracks in your inground pool? Scary, I know. Cracks in a gunite or concrete pool can conjure up all sorts of fears of much worse things. In most cases, pool cracks do not continue to crack, and can be permanently repaired.
Allow me to make a distinction between surface crazing, or check-cracks in the plaster and cracks that run through the pool shell. Its not uncommon for plastered pools to develop small, hairline cracks in the surface of the plaster, especially close to the surface, on the top steps for instance.
Cracks that run deeper can be seen in the corners, or where a spa wall joins the pool wall, or may develop behind the tile line, in the bond beam of the pool.
Todays post is all about How to Repair Cracks in an Inground Pool, in 3 ways the easy way, moderately difficult, and extreme crack repair. The level of difficulty for pool crack repair also tends to match the level of permanence. The more work you put into repairing a pool crack tends to correspond to the longevity and permanence of the repair.
