Radiant semi-inground pools are a popular choice for homeowners who want the strength of an inground pool with the flexibility of an aboveground design. To get the most from your pool and ensure it lasts for years, here are some important installation and maintenance tips to keep in mind.
Backfilling the Right Way
When backfilling around your Radiant pool, always use structural fill — not expansive soils like clay. Structural fill compacts well and creates a stable base for your pool walls.
-
Backfill gradually as the pool fills with water.
-
Compact by hand every 8–12 inches (avoid heavy machinery).
-
Hand backfill around skimmers, lights, and plumbing to avoid damage.
-
Always ensure pipes are buried, but not crushed.
Pro tip: If you backfill completely before filling the pool with water (not recommended), be sure to brace straight walls at the top.
Drainage Matters
Proper drainage is one of the most important steps in protecting your pool.
-
Install a French drain system with perforated pipe to direct groundwater away.
-
Never leave your pool empty — an empty pool is more vulnerable to wall damage.
-
Prevent standing water near the pool walls to avoid corrosion.
Even though Radiant’s aluminum walls are highly resistant to corrosion, long-term exposure to wet soil can still cause damage.
Concrete Collars for Extra Support
For Metric Series Pools installed semi- or fully inground, a concrete collar is required when walls are 26″ or more below ground.
-
Collar must be 16″ wide and 8″ deep (typically 3–6 yards of concrete).
-
Thermoplastic steps also require full backfilling and a concrete collar.
This collar works with drainage to ensure long-term strength and stability.
Electrical Bonding
Electrical safety is critical. All pools, including Radiant, must be installed following National Electric Code (NEC) guidelines.
-
Use 8 AWG bare copper wire connected to anchor plates around the pool bottom.
-
Ensure bonding of pool water, any nearby metal objects, and pool equipment.
-
Always follow local code requirements.
Pro tip: Always hire a licensed electrician who knows local pool bonding codes.
Salt Chlorination Systems
Salt systems can be used safely with Radiant Pools, but they require extra care:
-
Regularly test and balance water chemistry.
-
Consider a sacrificial anode to help prevent corrosion.
-
Check for stray electricity in the ground.
Radiant walls are extremely corrosion-resistant, but poorly maintained chemistry can accelerate wear.
Winterizing Your Radiant Pool
Winterizing correctly helps protect your investment. Here’s a simplified checklist:
-
Remove ladders, toys, cleaners, and store them away.
-
Balance the water, add winter chemicals, and clean thoroughly.
-
Lower the water just below the skimmer.
-
Plug return inlets with winter plugs.
-
Drain pump and filter lines (follow manufacturer instructions).
-
Prepare skimmers with gizzmos or plates to prevent ice damage.
-
Install the winter cover correctly, ensuring it rests on the water.
-
Check water levels under the cover after one week to catch leaks early.
Final Thoughts
Radiant semi-inground pools offer durability and beauty — but like any pool, proper installation and maintenance are key to longevity. From backfill and drainage to electrical bonding and seasonal care, following these tips will keep your pool safe and enjoyable for years to come.
