Many homeowners love the idea of a backyard pool, especially an Intex pool. They’re affordable, easy to set up, and fun for all ages. But picking the right spot can be confusing. If you have a concrete slab or patio, you might wonder: can you put an Intex pool on concrete? The answer is yes, but there are important things to know before you start. Let’s dive into the details and make sure your pool is safe, comfortable, and lasts as long as possible.
Why Consider Concrete For Your Intex Pool?
Concrete is a popular surface for above-ground pools for several reasons. It’s strong, flat, and can handle the weight of thousands of gallons of water. With the right preparation, a concrete base can even help your pool last longer. But there are also risks if you don’t set things up correctly.
Benefits Of Concrete Surfaces
- Stability: Concrete won’t shift or settle like dirt or grass, so your pool stays level.
- Durability: A concrete base won’t rot, erode, or get muddy.
- Cleanliness: There’s less dirt, grass, or insects getting into your water.
Common Concerns
- Hardness: Concrete is rough and unforgiving. The pool liner may wear out faster without padding.
- Heat: Concrete can get very hot in the sun, which can be uncomfortable under bare feet.
- Drainage: Water can pool around the base if the area isn’t sloped correctly.
Can You Put An Intex Pool Directly On Concrete?
Technically, you can place an Intex pool right on concrete. But most experts don’t recommend putting the pool directly on bare concrete. Here’s why.
Risks Of Bare Concrete
- Liner Damage: The rough surface can cause small holes or tears, leading to leaks.
- Uncomfortable Surface: Walking or sitting inside the pool can be hard on feet and legs.
- Warranty Issues: Some pool warranties may not cover damage from improper installation.
What Intex Recommends
Intex’s own instructions suggest always using a ground cloth or protective barrier under your pool, regardless of the surface. This helps prevent punctures and adds comfort.
Essential Steps Before Setting Up An Intex Pool On Concrete
Getting your pool base right is critical for safety and pool life. Here’s what you need to do before setting up your Intex pool on concrete.
1. Inspect And Prepare The Concrete
Check the slab for cracks, holes, or sharp edges. Sweep it clean to remove debris, stones, or anything that could damage the pool liner. Fill in any gaps or rough areas with patching compound.
2. Measure And Mark The Area
Use a tape measure to check the pool’s size. Mark the spot on your concrete, making sure there’s extra space around the pool for walking and setup.
3. Check For Level
Even small slopes can make your pool lean, which stresses the frame and liner. Use a long level or a laser level. If the concrete isn’t flat, you may need to grind down high spots or add leveling compound.
4. Plan For Drainage
Concrete doesn’t absorb water. After rain or splashing, water can collect around your pool. Make sure water drains away from the pool and your house. Sometimes, you may need to create small channels or use a wet vac to remove excess water.
Choosing The Right Underlayment
The most important step for putting an Intex pool on concrete is picking the right underlayment. This is a layer between the concrete and your pool’s liner.
Common Underlayment Options
Here are some popular choices, with their pros and cons.
| Underlayment Type | Pros | Cons |
|---|---|---|
| Intex Ground Cloth | Included with many pools, easy to use | Very thin, limited protection |
| Pool Foam Mats | Soft, good protection, easy to cut to size | Extra cost, needs taping at seams |
| Carpet Padding | Thick and soft, affordable | Can absorb water, may mold if not dried |
| Outdoor Rugs | Easy to find, resists water | Not as soft as foam, may slip |
| Old Blankets or Towels | Cheap, easy to replace | Not very durable, can bunch up |
What’s Best For Comfort And Protection?
Foam mats (like interlocking gym mats) are one of the best choices. They’re thick enough to protect the liner from the concrete’s roughness. They also make the pool floor much more comfortable. For larger pools, using a combination (foam mats plus a ground cloth) adds even more safety.
Two Insights Beginners Often Miss
- Double Layering Helps: Using both a foam mat and a ground cloth together gives much better protection than either one alone.
- Don’t Overlap Seams: When using foam mats, stagger the seams so they don’t line up, which prevents weak spots under the liner.
Setting Up The Pool: Step-by-step Guide
Once your base is ready, it’s time to set up your Intex pool. Here’s how to do it right.
1. Lay Down The Underlayment
Place your chosen underlayment over the clean, level concrete. Make sure it covers the whole pool area, with no gaps. If using foam mats, tape the seams so they don’t move.
2. Unfold And Center The Pool
Carefully spread the pool liner over the underlayment. Make sure the liner is centered and smooth out any wrinkles.
3. Assemble The Frame
Follow the Intex instructions for your pool type (Easy Set, Metal Frame, Ultra XTR, etc. ). Assemble the frame or inflate the ring as needed.
4. Add Water Slowly
Begin filling the pool with a few inches of water. As it fills, smooth out any wrinkles on the bottom by gently pulling the liner toward the edges.
5. Check For Level Again
As the pool fills, check that the water stays level all the way around. If you see one side rising higher, you may need to adjust.
6. Finish Filling And Install Accessories
Once the pool is full and level, set up your pump, ladder, and any covers or floats.
Safety Tips For Intex Pools On Concrete
Safety is always important around water. When your pool is on concrete, there are a few extra things to watch for.
Padding Around The Pool
The area just outside your pool can get wet and slippery. Consider placing rubber mats or non-slip outdoor rugs around the pool to prevent slips and falls.
Protecting The Liner
Never let sharp objects near the pool. Shoes, toys, or tools can puncture the liner if dropped.
Supervision
Always supervise children. Concrete is less forgiving than grass if someone slips and falls outside the pool.
Comparing Pool Placement Options
How does concrete compare with other popular pool bases? Here’s a look at the strengths and weaknesses.
| Surface | Pros | Cons |
|---|---|---|
| Concrete | Stable, level, durable | Hard, needs padding, can get hot |
| Grass | Soft, comfortable | Can rot or get muddy, may shift |
| Sand | Easy to level, soft for feet | Can wash away, may not stay flat |
| Decking | Looks nice, can be slip-resistant | May not support heavy pools, expensive |
How Concrete Affects Pool Maintenance
Placing your Intex pool on concrete can change how you care for it. Here’s what to expect.
Less Grass And Dirt In The Water
Since you’re not on the lawn, there’s less chance of grass, soil, or mud getting into the pool. This means less cleaning and fewer clogs in your filter.
Watch For Abrasive Wear
The liner can wear faster on concrete, especially if the underlayment is thin or moves around. Check for signs of wear during the season. If you feel a thin spot, drain the pool and add more padding.
Dealing With Heat
Concrete gets hot in the sun. This can warm the pool water—good for chilly days, but uncomfortable in summer. Placing a solar cover on the water when not in use can help control temperature.

Extending The Life Of Your Intex Pool On Concrete
Want your pool to last for many summers? Take these extra steps.
Use A High-quality Pad
Invest in thick, closed-cell foam pads. They last longer and offer better protection.
Cover The Pool When Not In Use
A pool cover keeps out debris, blocks UV rays, and protects the liner from sun damage.
Check For Shifting And Damage
Every few weeks, look under the pool edge to check that the underlayment hasn’t moved and the liner looks healthy.
Store Properly In Winter
If you live in a cold climate, drain and dry the pool completely at the end of the season. Store it indoors, away from sunlight and moisture.
Mistakes To Avoid When Placing An Intex Pool On Concrete
Even with the best intentions, common errors can lead to problems. Here’s what to watch out for.
Skipping The Underlayment
Never place the pool directly on concrete. Even a small stone or rough spot can destroy your liner over time.
Using The Wrong Padding
Some people use cardboard, old carpet, or thin tarps. These break down quickly and offer little protection. Always use materials rated for outdoor and wet use.
Not Checking For Level
If the pool leans, the frame can twist, and water may spill out. Check the level before, during, and after filling.
Letting Water Sit Under The Pool
If your concrete isn’t sloped for drainage, puddles can stay under the pool. This can lead to mold, mildew, and slippery surfaces.
Ignoring Local Codes
Some cities have rules about pool placement. Always check with local authorities before setting up your pool.
Real-life Example: Intex Pool On A Backyard Concrete Patio
Let’s look at a real example. Sarah wanted a summer pool for her kids. She had a 15×15 foot concrete patio and bought a 12-foot round Intex pool.
- She cleaned the patio and patched a small crack.
- She used thick interlocking foam mats and taped the seams.
- She added the Intex ground cloth on top for extra protection.
- She set up the pool, checking level at each step.
- After filling, she placed outdoor rugs around the pool to prevent slips.
Sarah’s pool lasted three summers with no liner damage. She noticed the water stayed cleaner than when she had a pool on grass. Her main tip: “Don’t skip the foam mats. They make a huge difference in comfort and liner life.”
Cost Considerations For Concrete Setups
You might think concrete is more expensive, but it can save money in the long run.
- Padding: Foam mats cost about $50–$100 for a medium pool.
- Ground Cloth: Usually included, but extra ones cost $20–$40.
- Repairs: Liner repair kits are cheap, but prevention is better than fixing.
- Longevity: A well-protected liner on concrete can last several years, reducing replacement costs.
Compare this to setting up on grass, where you may need to reseed, level, or replace muddy areas.

Addressing Heat And Comfort
Concrete’s heat can be a problem in sunny areas. Here’s how to handle it.
- Shade: Set up your pool where part of it gets shade during the day.
- Outdoor Rugs: Place them where people climb in and out.
- Water Sprayer: Use a hose sprayer to cool the concrete before swimming.
These little steps can make your pool area much more pleasant.
Important: Check Your Intex Pool Warranty
Some Intex pool warranties state that damage from improper surfaces isn’t covered. Always read the warranty booklet before setup. If you damage the liner by placing it directly on concrete, you may not get a free replacement.

Pool Size And Weight Concerns
Larger pools put more pressure on the concrete. Here’s a quick look at how much weight different pool sizes add.
| Pool Size | Water Capacity (gallons) | Total Weight (pounds) |
|---|---|---|
| 8 ft Round | 640 | 5,340 |
| 12 ft Round | 1,718 | 14,330 |
| 15 ft Round | 3,861 | 32,170 |
| 18 ft Round | 6,423 | 53,570 |
Most standard patios can support an Intex pool, but always check your slab’s thickness and condition if you have a very large pool.
Winterizing Your Intex Pool On Concrete
If you live where winters are cold, you need to protect both the pool and the concrete.
- Drain the pool completely before freezing weather.
- Clean and dry the liner to prevent mold.
- Store the liner and parts indoors.
- If the concrete gets icy, use a broom (not a metal shovel) to avoid damaging the slab.
When Not To Put An Intex Pool On Concrete
While concrete is usually safe, there are situations where it’s not a good idea:
- Severely cracked or uneven concrete can cause the pool to lean or the liner to tear.
- Painted or sealed concrete can be slippery and may peel under the pool’s weight.
- New concrete should cure at least 30 days before placing a pool on it.
Alternatives To Concrete
If your concrete isn’t suitable, you can build a frame or pad with compacted sand, gravel, or pavers. Just make sure the surface is level, stable, and protected by a good underlayment.
Environmental And Local Regulations
Some cities have rules about water usage, pool fences, or drainage. Check local codes before you set up your pool. Violating these rules can lead to fines or forced removal.

Frequently Asked Questions
Can I Use A Tarp Instead Of Foam Mats Under My Intex Pool On Concrete?
A tarp is better than nothing, but it’s not as effective as foam mats. Tarps are thin and can bunch up, offering little comfort or protection. Foam mats are thicker, help protect the liner, and make the pool feel softer underfoot.
How Do I Know If My Concrete Slab Is Strong Enough For An Intex Pool?
Most residential concrete patios are 4 inches thick and can hold the weight of even large Intex pools. However, if the concrete is cracked, thin, or damaged, consult a contractor before setting up your pool.
Will Placing My Intex Pool On Concrete Void The Warranty?
Intex recommends using a protective barrier under the pool. If you put the pool directly on concrete without padding and the liner is damaged, warranty coverage may be denied. Always read the warranty booklet and follow setup instructions.
How Do I Keep The Concrete Cool Around My Pool?
Use outdoor rugs, shade sails, or spray the concrete with water before swimming. You can also set up the pool in a shaded area if possible.
Is It Ok To Leave My Intex Pool On Concrete All Year?
If you live in a warm area with mild winters, you can leave the pool up. However, freezing temperatures can damage both the pool and the concrete. It’s best to drain, clean, and store the pool during the winter in colder climates.
Placing an Intex pool on concrete can be a smart, long-lasting choice when done correctly. With proper preparation, padding, and care, you’ll enjoy cool, clean water all summer—without worrying about liner damage or shifting surfaces. Always check your local rules and the pool’s instructions to get the best results for your backyard oasis.
