Other Cause For Concrete Decks To Crack

How to fix cracks and holes on a concrete pool deck.
  • No reinforcement or minimal reinforcement in the concrete. Reinforcement like steel rebar or wire reinforcing mesh makes concrete stronger and reduces cracking.
  • Weakened concrete. If a low strength concrete was poured or too much water was added when the concrete was placed; then the concrete may be weaker than normal.
  • Tree roots are often the culprit that causes sidewalks, driveways and patios to crack and likewise they may cause pool deck slabs to crack.

Concrete Pool Deck Cracks: Causes Types Repair Methods

You dont have to spend a ton of money to have a beautiful deck around your swimming pool.

Enter concrete.

Concrete pool decks are affordable, relatively easy to maintain, and easy to customize. They can also be comparable in aesthetics to more expensive pool decking materials.

While concrete has a reputation for being strong and durable, its also prone to cracking. By that, we mean its almost inevitable that your concrete pool deck will crack at some point in time.

As fiberglass pool manufacturers with years of installation experience, we can confirm that cracking concrete is a common issue in pool decks. Because its such a widespread problem for everyone who has concrete on their property , were going to explain how concrete cracks, why it cracks, and what you can do to repair it.

Concrete usually cracks for at least one of the following reasons:

  • Structural settling
  • Poorly placed control or expansion joints
  • Improperly mixed concrete
  • Fluctuations in temperature

Cracks in a concrete deck can be the first sign of structural settling or ground movement. If the cracks are still active, you need to hire an engineer to find out the cause and get to the root of the problem before you try to patch the cracks in your pool deck. This is especially important for cracks close to the pool because it can mean bigger and more expensive problems for your swimming pool in the future if you dont act fast.

How Polylevel Works To Repair Your Settled Pool Deck

PolyLevel is a high-density expanding foam that our technicians can use to raise settled concrete. The two-part polyurethane foam mixture is injected through small holes drilled in the settled concrete. Our installers are trained to control the injection process so that just enough foam is used to re-level the concrete deck and fill additional voids under the concrete. Because the foam’s expanding action fills gaps in loose soil, this concrete leveling technique improves the soil’s stability and load-bearing characteristics. You can feel confident that settlement won’t occur again. Once the slabs have been lifted level, we can also provide a silicone polyurethane sealant that will keep water from going through any joints and causing future erosion or possible heave situations.

Three Main Causes For Pool Cracks

1. Improper engineering and design

If a pool is not properly designed and engineered, then the likely hood of the shell to crack increases. Often the first flaw of engineering a pool is failure to test the soils and engineer the pool based on the soil load bearing capacity and stability. Soils with a clay content, usually called expansive soils, are one of the more problematic types of soils. Additionally, poor design of the areas around the pool plays a part in the overall picture; retaining walls and the concrete deck areas around a pool are a perfect example.

2. Poor workmanship

Failure to follow the construction plans when building the pool or taking shortcuts is a large part of why a pool will crack. Simple things like adding too much water to the gunite or shotcrete when spraying it on the rebar or failure to adequately tie the rebar in place when placing the rebar, may cause cracks. Even not keeping the pool sufficiently moist after the concrete is sprayed on, especially in hot climates or hot days will cause cracking.

3. Soils issues

Soil issues are another major reason for a pool to crack. If the contractor left uncompacted soil when digging the pool hole and then built the pool on this poorly compacted soil, it may result in cracking. Soil movement, especially on hillsides, likewise may cause cracking; on flat lots with expansive soils or even earthquakes can cause a pool to crack.

While concrete is a tough material, it does have its limitations. Over the course of several years, extreme temperatures and other conditions can cause it to warp, crack, degrade, and chip away.

Because of that, you might notice that your relatively new driveway already has some cracks in it. Fear not, because today we are here to help you learn how to fix cracks in concrete. We will cover four methods that will help you deal with cracks of all sizes

Pool Coping Grout Repair

Typically pool coping has the main purpose of joining together the horizontal deck with the vertical walls of the pool.; It acts with a sense of architectural presence protecting the pools beam.

If water can actively penetrate the grout, it may cause the walls of the pool to shift, and as a side effect, major damage can occur to the pool.

It becomes necessary to repair brick coping when damage can visually be spotted with the naked eye.; However, in cases where only the grout is damaged, simply remove the old grout.; Fill the old joints with new grout in order to seal out moisture and protect the pool from any long-term damage or side effects.

Remember that if you are repairing the pool grout yourself, it sets in faster than other types of structures so be aware that it dries faster.; Pool grout differs from the grout that may be used in household tiles as it has a greater degree of flexibility.

The flexibility allows for a greater range of expansion and contraction to handle all different weather climates and variations.

Although grout can be repaired in a fairly simple manner, if the damage is too severe, there is a chance that an entire pool deck may need to be remodeled.

Remodeling a pool deck is one way to improve the appearance of your backyard while also increasing the value of your home in the process.

Concrete Crack Leak Sealing Injection With High

This is because the TDI;polyurethane;is injected deep into the building element forced under high pressure. This high-quality fluid resin is injected into concrete cracks, rock fissures and other voids in concrete structures. Once the product is inside the crack, it chases the water present in the crack and begins to foam and expand filling the entire crack.

The polyurethane undergoes a chemical transformation from a liquid to a solid when reacting with water. The product has a very short cure time, making it ideal for active leak sealing. It sets in minutes, forming a dense, durable and flexible seal;preventing future water leaks.

The low viscosity allows for the fine cracks with a width less than 0.2mm to be sealed, so any leak in concrete structure can be sealed in concrete structures.

Polyurethane crack injection is without a doubt the most effective leaking crack repair method in concrete swimming pools. It is commonly used in civil, commercial and residential leaking concrete crack injection.

There are many different types of polyurethane products available in the market. Waterstop Solutions uses the highest quality polyurethane resin formulations, which ensures the optimum cure time, viscosity, efficient and reliable results for each different type of application.

Waterstop Solutions utilises the same techniques and products that we have approved for use on major civil structures with a design life of 100 years.

Should I Try To Fix My Pool Deck Myself

Some concrete repairs can be done as a DIY, but it is highly recommended to hire a contractor for more complicated tasks. There are many patching and filling products available that make fixing small cracks easy for a homeowner to do themselves.

However, if the job requires you to do a full resurface, or use materials that need to be leveled, a professional contractor will be the best choice for your project. A contractor is more likely to complete the job on time, without error, and with a finished look youll enjoy for years to come.

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.

V Shaped Cracks On Wall Of Pool

When a crack is V shaped, wider at the top than the bottom, and its a vertical crack on the wall of the pool; then there is a strong possibility that that one of several things have occurred.

  • There was poor compaction at one end or side of the pool, therefore there was inadequate support for the pool bottom in that area.
  • The pool had uneven settlement because it was built on cut and fill.
  • There is expansive soils and there is a leak or a source of water penetrating into the expansive soils under the pool. Thus causing soil movement.
  • Slope creep has occurred, causing the crack.

V shaped cracks are one of the more serious types cracks that a pool may incur and the probability that there is a leak is rather high.

Hairline Cracks In Pool Deck Common

How to repair cracks in concrete pools.

Question: I have a pool deck that is about 2 years old that has a hairline crack extending from the outside edge and across and through three saw-cut expansion joints. This crack is about 20 feet long and about 1/16-inch wide or smaller.

I am sure the crack was caused from settling. I have repaired this crack twice using an exterior flexible-patching compound that has an elastomer in it. I applied this substance using a putty knife. Both times I allowed this substance to dry at least 48 hours before repainting.

The crack keeps coming back. Can you recommend a do-it-yourself way to repair this crack without having to saw-cut it?

Answer: Cracking is a common occurrence in all concrete flat work.

Look beyond your pool deck to your sidewalk and driveway, even inside your home for cracks that are caused by many factors, including settling, shrinkage, expansion and contraction.

“The most common cracks in pool decks are hairline cracks like you have,” says Steve Bludsworth, owner of All-Pool Service and Supply in Orlando.

Most cracks result from the concrete constantly moving because of hot/cold and wet/dry conditions, Bludsworth says.

Movement of the ground also causes cracks.

Even though this movement is normally very small, it makes a permanent repair elusive.

Caulking, epoxy injection, saw-cutting and patching are some of the repairs used with limited success.

Many times the attempted repair is much more of an eyesore than the original crack.

Drain the pool completely. Remove at least two hydrostatic relief plugs from the pool floor. Using a 4-inch grinder, widen the crack and make it into a reverse V shape. Next, dampen the crack. Ensure that it remains moist as you apply a bonding additive until the crack is filled up. Use hydraulic cement if it is over an inch deep, then add pool plaster for a smooth finish. However, it is best to get the best pool repair service in Sarasota, especially if your pool has structural cracks.

How To Repair Concrete Pool Decks

Owning a swimming pool can be a great experience for a homeowner, until they start to have problems.; One typical problem for swimming pools, especially those located in areas of the country with four seasons where the weather goes from hot in the summer to freezing in the winter, is dropped, sunken or settled concrete pool decks. When that happens, its difficult to know what to do or who to call for concrete pool deck repair.

A good place to start might be to consider why your concrete pool deck settled in the first place. When your in-ground pool is installed, excavation of soil is involved.; What once was stable, compact soil gets disturbed or displaced to install the pool.; Once the pool is installed, that disturbed soil gets put back in place. Following the pool installation itself is the pool deck installation. Unfortunately, its not uncommon for disturbed soil under the concrete pool deck begins to settle.; Its actually fairly common and the challenge is, this settling may not result in cracking, sinking or dropping of the concrete pool deck for 7 years or more.

If you are a homeowner or business owner that is experiencing sinking of your concrete pool deck, the best approach is to contact a good concrete repair company to come out, assess the situation, and provide a quote for services.

Concrete Pool Deck Restoration With Polylevel

Some contractors still use the old-school repair for settled concrete. They use heavy equipment to demolish the cracked, settled sections of concrete around your swimming pool and pour a new concrete deck. With concrete replacement, you often get a damaged yard and a pool that’s off-limits until the new concrete hardens and cures. More importantly, the new concrete is going onto the same soil problem, which caused the issue in the first place.

Another method is mud jacking but leaves the pool deck with noticeable injection holes that are 1″-2″ in diameter. The material used in mud jacking is not waterproof, which could wash out if not properly sealed, but the material is weighty. Knowing the weight of the original concrete pool deck over a poor soil base is usually what causes settlement in the first place. By adding additional weight, you’re asking for further settling to occur. Our concrete leveling method saves you time and money and won’t disrupt your landscaping. Injecting PolyLevel expanding foam beneath a settled pool deck will raise the concrete back to the proper level and also strengthen the soil so that the problem won’t recur.
