What To Put Under Above Ground Pool

What to Put Under an Above Ground Pool: A Comprehensive Guide

Choosing the right base for your above-ground pool is crucial for its longevity, stability, and overall enjoyment. A poorly prepared base can lead to uneven settling, leaks, and even structural damage. This guide explores the best options for what to put under your above ground pool, helping you make an informed decision that ensures years of splashing fun.

What's the goal? The primary objective is to create a level, stable, and well-drained foundation that prevents the pool from sinking, shifting, or damaging the surrounding ground. This involves considerations of your soil type, pool size and weight, and local climate.

Understanding Your Soil Type

Before you even begin thinking about materials, assess your soil. Clay soil, for example, is notorious for retaining water, which can cause significant problems. Sandy soil, on the other hand, drains well but might require additional compaction. Knowing your soil type helps you choose the best base material and preparation techniques.

The Best Options for Your Above Ground Pool Base

Several options exist, each with its own pros and cons:

1. Pea Gravel: A popular and cost-effective choice, pea gravel provides excellent drainage. Its small size allows for a relatively even surface, yet it's still permeable enough to allow water to escape. However, it can shift over time, requiring periodic maintenance. Consider a thicker layer (at least 4 inches) for better stability.

2. Compacted Sand: A well-compacted layer of sand provides a stable and level base. It's relatively inexpensive and easily available. While it offers decent drainage, it's not as effective as pea gravel in very wet conditions. Remember to thoroughly compact the sand in layers for optimal results, using a plate compactor for a professional finish.

3. Concrete Slab: The most durable but also most expensive option, a concrete slab offers unparalleled stability and longevity. It's particularly beneficial in areas with poor soil conditions or heavy pool weight. However, it requires more preparation and expertise, potentially necessitating professional installation. This is a good long-term solution, eliminating the need for future repairs or concerns regarding shifting.

4. Patio Stones or Pavers: This offers a visually appealing and relatively stable base, especially if your pool is part of a larger patio area. Ensure the stones are properly level and compacted to prevent settling. This option, while aesthetically pleasing, can be more expensive than gravel or sand.

5. Weed Barrier Fabric: Regardless of your chosen base material, placing a weed barrier fabric underneath is highly recommended. This prevents weeds from growing up through the gravel or sand, simplifying maintenance and preventing potential damage to the pool liner.

Preparation and Installation

Regardless of your chosen base, these steps are vital:

• Level the Ground: Use a level to ensure the ground is perfectly level. Any unevenness will translate into an uneven pool.
• Compaction: Thoroughly compact the chosen base material, especially sand or gravel, to prevent settling.
• Proper Drainage: Ensure the area around the pool has adequate drainage to prevent water pooling. This might involve creating a slight slope away from the pool.
• Professional Help: For larger pools or challenging soil conditions, consider seeking professional installation to ensure the job is done correctly and safely.

Choosing the Right Option for You

The best option depends on your budget, soil type, and desired level of stability. Pea gravel offers a balance of cost-effectiveness and drainage. Compacted sand provides a solid base at a reasonable price. A concrete slab guarantees ultimate stability but comes with a higher price tag. Patio stones provide an aesthetic upgrade but demand careful installation. Remember to always use a weed barrier to protect your investment. By carefully considering these factors and following these steps, you’ll create a secure and stable foundation for your above-ground pool, ensuring many years of enjoyable summer swims.
