Don't Wing It - Use These Tips to Perfectly Level the Pool Ground
Installing an in-ground swimming pool is an exciting project that opens up new possibilities for backyard fun and relaxation. But before you start envisioning pool parties and lazy summer days lounging poolside, the critical first step is proper site preparation - leveling and grading the ground where your pool will be located.
Taking the time to get the base right ensures your pool structure is soundly supported and built to last. Read on for tips to perfectly level the area prior to pool construction.
Choose the Right Location
When selecting where to situate your pool, consider how the space will be used and how it fits with the rest of your landscape. Look for a spot that gets ample sunlight, has good views from your home, and allows convenient access from the house. Avoid placing the pool under or near large trees that will shed leaves and debris into the water.
Also factor in drainage patterns across your property. The pool area should be graded to prevent water from collecting or eroding the soil. A professional landscaper can assess drainage needs specific to your site.
Clear and Prepare the Site
Once you've identified the ideal pool location, the real work begins! Start by removing all vegetation from the footprint. Use a sod cutter or shovel to strip grass down to bare soil. Take out any trees, stumps, rocks and stubborn roots in the area.
Next, till the top 4-6 inches of soil with a rototiller or excavator bucket. This loosens and breaks up the ground, making it easier to level. Remove and dispose of all waste materials properly before moving on.
Use Leveling Tools to Identify High and Low Spots
With the blank slate prepped, it's time to start leveling. Use an accurate tool like a laser level, transit level, or digital smart level. These provide precise measurements to pinpoint high and low points.
Methodically check elevations every 3-5 feet across the entire site, marking slopes and depressions with spray paint or stakes. Be meticulous at this stage - any areas that are off-level now will affect the finished pool.
Types of Levels
- Spirit level - basic manual tool with bubble vial
- Laser level - projects a laser beam to mark level points
- Digital level - electronic readings shown on digital display
How to Use a Level
Place level on a straight, rigid surface. Note if bubble is centered between lines - this indicates level. If not, identify which direction is higher/lower. Move level to determine extent of slope.
Dig Out and Fill In Areas as Needed
Looking like a patchwork quilt yet? Now comes the grunt work of actually fixing the topography. Excavate high areas down to the desired elevation. Be sure to tamp and compact the soil so it does not settle.
For low spots, add layers of clean fill dirt, concrete sand, or gravel. Compact each layer before adding more material. Overfilling is better than underfilling, as you can always remove extra.
Key Tips for Digging and Filling
- Work in small sections for best control
- Keep fill dirt slightly moist to aid compaction
- Add layers no more than 6 inches deep before compacting
Add and Smooth Out Sand Base
When the entire area is closer to level, spread a 2-inch layer of concrete or masonry sand across the surface. Use a hand tamper or lawn roller to compact until perfectly flat. The sand blankets minor dips and bumps to produce a smooth finish.
Avoid walking on the sand or disturbing the area once it's smoothed out. The graded base should remain untouched until pool construction begins.
Double Check Levels and Make Final Adjustments
Before calling the grading complete, meticulously recheck elevations across the whole site again. Even with meticulous work, some slight settling can occur after tamping down fill. Use your level to identify any remaining high or low spots and make adjustments as needed.
Confirm there is no more than 1/8-inch variation across a 10-foot section. The flatter the better for a sound pool foundation.
Prevent Erosion and Drainage Issues
To protect your pristine pool prep, consider incorporating drainage systems if needed. Swales, French drains, or rain gardens help prevent waterlogging. Place erosion control blankets or sod around the perimeter before excavation begins.
Always recheck drainage performance after heavy rains or spring thaws. Proper grading should keep water moving away from the pool area.
Consult the Experts
Finally, don't be afraid to call in reinforcements! Experienced pros like excavation contractors or landscapers have the specialized tools and knowledge to advise on site conditions. A pool installation company can also provide input before the final grading is complete.
Investing in expert guidance gives you confidence that the base preparation meets all requirements for proper structural support, water balancing, and service equipment.
Perfectly leveling the ground for a pool takes planning, patience, the right tools, and meticulous work. But the effort pays off with a solid underpinning that gives your pool a long, problem-free lifetime. So don't wing it - take it from the top and use these tips to get the site properly graded before installing your backyard oasis.
