How to Prepare the Ground for Pavers
Step 1: Choose the right location
- Soil stability – steer clear of clay-heavy areas that might shift like gelatin
- Easy access to electricity (nobody wants 100-foot extension cords!)
- Close enough to your home for those chilly winter dashes
- Privacy from nosy neighbors and great views while you soak
- Enough space around all sides for maintenance (a couple of feet is ideal)
Step 2: Excavate and level the area
- Strip away all grass, plants, rocks, and debris from your marked area
- Dig out the topsoil at least 2-4 inches deep to prevent future settling when your hot tub makes itself at home
- Make your excavated area slightly bigger than your hot tub’s footprint for a proper foundation edge
- Firmly tamp down the exposed dirt to stop any sneaky shifting later
Step 3: Add gravel and compact it
- Roll out heavy-duty stabilization fabric over your excavated area to block weeds and add support
- Pour in crushed rock or gravel to a thickness of 4-6 inches minimum
- Choose crushed rock over pea gravel – those angular edges lock together much better than smooth round pebbles
- Spread the gravel evenly across your entire hot tub zone
- Compact thoroughly with a plate compactor until it feels rock-solid
Step 4: Add sand and screed it flat
- Add a 1-inch blanket of coarse sand over your compacted gravel
- Grab a straight board and screed (level) that sand perfectly flat
- Check multiple directions with a long spirit level – no cutting corners here!
- Adjust by adding or scooping out sand until it’s perfectly level
- Lightly spray the sand with water to help it settle into place
Do’s and Don’ts of ground preparation
Do’s
- Do install a 4-6 inch reinforced base of properly compacted gravel
- Do use pressure-treated 4×6 lumber rated for ground contact to frame your base
- Do ensure your foundation is perfectly level before placing pavers
- Do include proper drainage in your base preparation
- Do use a geotextile fabric beneath gravel to prevent weed growth
- Do extend your preparation area beyond the hot tub dimensions
Don’ts
- Don’t use pea gravel as it doesn’t compact properly
- Don’t place pavers directly on topsoil or grass
- Don’t skip the compacting process at any stage
- Don’t ignore manufacturer’s requirements for pad thickness
- Don’t rush the base preparation – it’s the most important step
- Don’t forget to check ground slope and soil stability first
Installing the Pavers for Your Hot Tub Base
Step 1: Select the right type of pavers
- Thickness matters – Grab pavers at least 2 inches thick for proper support
- Material strength – High-density concrete pavers give you that rock-solid durability
- Surface texture – Smooth, flat surfaces create an even foundation without wobbles
- Interlocking design – Pavers that fit together like puzzle pieces won’t shift under pressure

Step 2: Lay the pavers in a level pattern
- Map out your pattern before laying a single paver – measure twice, place once!
- Buy about 10% extra pavers – trust me, you’ll thank yourself when you need that odd piece
- Place each paver with care, checking level as you go (no shortcuts here!)
- Already have a patio? For uneven surfaces, consider using leveling pavers specifically under your Caldera Spa
Step 3: Fill joints with polymeric sand
- Clean those joints completely – even tiny debris can mess with proper bonding
- Pour that magical polymeric sand between your carefully placed pavers
- Sweep it across evenly, making sure every gap gets properly filled
- Run your plate compactor over the surface to help the sand settle deep into the joints
- Mist with water according to the sand manufacturer’s directions to activate the bonding agents
- Patience pays off! Allow 24-48 hours of curing time before the next steps

Step 4: Check for level and stability
- Grab that long spirit level and check multiple spots – a tilted tub is a sad tub
- Press each paver firmly – any wobbling means trouble ahead
- Hunt for sand gaps that need extra filling – complete coverage is key
- Double-check your edge restraints – they’re your defense against shifting
Common mistakes to avoid
| Do | Don’t |
|---|---|
| Install edge restraints to keep everything locked in place | Skip compaction at any point – this isn’t the place to cut corners |
| Test each paver for rock-solid stability | Use skinny pavers under 2 inches thick – they’ll crack under pressure |
| Give polymeric sand proper time to cure completely | Install pavers without sturdy edge support – they’ll spread like dominoes |
| Choose high-density, thick pavers made for heavy loads | Leave joint sand gaps unfilled – they’re your stability secret |
