The Importance of Pool Drainage & Proper Groundwork
Building on a Solid Foundation
Building a swimming pool is an exciting project that transforms your backyard into an oasis. However, to ensure your pool is structurally sound, long-lasting, and functional, it’s crucial to focus on two often-overlooked aspects during the construction process: proper drainage and groundwork. At Foley Pools, we understand that the foundation of a successful pool build starts with getting these elements right. Here's why proper drainage and groundwork are essential for a smooth, lasting pool installation.

Why Proper Draining is Critical
Effective drainage is one of the most important components in ensuring the long-term stability of your pool. Without it, water can accumulate around the pool area, leading to several issues that can compromise the structure and performance of your pool.
Prevents Water Damage to the Pool Structure
When constructing a pool, it’s vital to divert excess water away from the pool area. Without proper drainage, rainwater or groundwater can pool around the structure, causing hydrostatic pressure, which can push up on the pool floor. This pressure can lead to cracks, leaks, or even cause your pool to shift over time.
Keeps the Pool Area Dry and Safe
Water accumulation around the pool area not only threatens the pool's structural integrity but also creates a slip-and-fall hazard. Proper drainage ensures that the surrounding pool deck and landscaping remain dry and safe for pool-goers, reducing the risk of accidents.
Helps Prevent Pool Heaving
In areas with high groundwater levels, pool heaving can be a significant problem. Without adequate drainage, the hydrostatic pressure from groundwater can lift the pool out of place. This can cause the pool to shift, crack, or become misaligned. A well-designed drainage system helps mitigate this risk by preventing water from accumulating around the pool’s shell.

The Importance of Proper Groundwork
Proper groundwork is the foundation of any pool construction project. It involves preparing the site and ensuring the soil conditions are suitable to support the weight of the pool and its surrounding structures.
A solid, level, and compacted foundation is essential to prevent shifting, settling, or cracking of your pool over time. If the soil beneath the pool is loose or improperly prepared, the weight of the pool and water can cause damage. Excavation and grading are key steps that ensure a stable base, with soil being properly compacted and leveled to bear the pool’s weight. This foundation prevents long-term structural damage, reduces maintenance costs, and ensures the pool remains intact for years.
Not all soils are suitable for pool construction. Expansive clay soils, for example, can shrink or swell with moisture, causing instability. Soil testing helps identify these issues early on, ensuring that the ground is prepared for construction. If necessary, soil treatments or additional reinforcements can be used to stabilize the ground. Proper soil preparation is crucial for the longevity of the pool and to prevent costly repairs down the road.
Effective drainage during excavation is essential to prevent water from accumulating around the pool, which could lead to hydrostatic pressure and structural damage. Proper grading ensures water flows away from the pool and doesn’t collect in low areas. Installing drainage systems like French drains or sump pumps helps manage groundwater and rainwater, protecting the pool’s structure and preventing issues like waterlogging or standing water that could harm the pool or its surrounding area.

Reinforcing Pools in North Texas
In North Texas, where expansive clay soil constantly shifts, proper pool reinforcement is essential to prevent cracks, leaks, and structural damage. Custom pools in the region require strong steel rebar frameworks, durable gunite or shotcrete, and advanced waterproofing techniques to withstand ground movement and seasonal weather changes. Investing in high-quality reinforcement ensures your pool remains stable, safe, and long-lasting, reducing costly repairs down the line.
An Extra Step
At Foley Pools, we choose steel-reinforced gunite for our custom pools because it provides the perfect balance of strength, flexibility, and durability. Gunite, combined with a robust steel rebar framework, creates a solid, crack-resistant shell that can withstand the shifting soil and extreme weather conditions common in North Texas. This method not only ensures the pool's structural integrity over time but also allows for greater design flexibility, allowing us to craft pools that are both long-lasting and visually stunning.

Common Questions About
the Importance of Pool Drainage & Proper Groundwork
-
Proper drainage is crucial to prevent water from accumulating around the pool, which can lead to hydrostatic pressure that may cause cracking, shifting, or leaking. Effective drainage helps direct water away from the pool area, protecting the structure and ensuring the long-term stability of your pool.
-
Improper groundwork can lead to shifting, settling, or cracking of the pool shell over time. Loose or improperly compacted soil beneath the pool can cause uneven settling, compromising the pool’s structural integrity. Ensuring proper excavation, grading, and compaction of the soil is essential for a stable foundation.
-
Soil testing helps determine whether the soil is suitable for pool construction. Certain soils, like expansive clay, can shrink or swell with moisture, leading to instability. Soil tests identify these issues and allow for the implementation of necessary treatments or reinforcements to create a stable foundation, reducing the risk of future pool damage.
-
Common drainage systems include French drains, sump pumps, and weeping tiles. These systems help manage groundwater and rainwater, directing it away from the pool area to prevent water accumulation, hydrostatic pressure, and soil erosion. Proper drainage installation is essential for the pool’s stability and safety.
-
Proper grading ensures that the ground slopes away from the pool, directing water away from the structure. This prevents water from pooling in low areas around the pool, which could lead to damage or erosion. Grading also helps ensure that the soil is level and compacted, providing a stable foundation for the pool.
-
Yes, improper drainage can cause water to pool around the pool deck and landscaping, leading to erosion, damage to surrounding features, and safety hazards like slippery surfaces. It can also promote the growth of algae and mold. Ensuring proper drainage helps keep the entire pool area safe, dry, and well-maintained.
-
Signs that drainage or groundwork may need attention include uneven settling of the pool, cracks in the pool shell, or water pooling around the pool area. If you notice any of these issues, it’s important to have a professional evaluate the situation and make necessary adjustments to the drainage or groundwork to prevent further damage.
