Pool Excavation, Steel & Plumbing

First three phases

The first three phases of the swimming pool construction process that include digging the hole, placing the steel reinforcement bars to create the skeleton structure of your pool, and running the rough plumbing within the steel.

Pool construction involves the process of building a swimming pool, from the initial planning and excavation to the installation of various components and finishing touches. The construction of a pool can vary in complexity depending on factors such as the type of pool, its size, design, and the specific features incorporated.

Here is an overview of the typical steps involved in pool construction:


Excavating the area according to the approved design. The excavation phase creates the hole for the pool, including any necessary slopes and levels.

Steel Reinforcement

Installing a steel framework or reinforcement to provide structural support for the pool’s shell. The steel is positioned according to engineering specifications.

Plumbing Installation

Installing the plumbing system, including pipes, drains, skimmers, and other necessary components. The plumbing ensures proper water circulation, filtration, and drainage.

Here are the key steps involved in pool excavation


Pool excavation refers to the process of digging and preparing the ground to create a hole or cavity for the construction of a swimming pool. This is a crucial step in the pool installation process and involves careful planning and execution to ensure that the pool’s dimensions, shape, and depth meet the desired specifications.

Site Preparation

Before excavation begins, the site is prepared by marking the pool’s layout, This involves accurately outlining the pool’s shape and dimensions on the ground.


The excavation process involves removing soil and other materials to create the hole for the pool. This is typically done using heavy equipment such as excavators or backhoes. 

Slope and Leveling

The excavated area needs to be carefully sloped and leveled to ensure proper water drainage and to meet the specified depth requirements for different sections of the pool.


After the excavation is complete, the soil is typically compacted to ensure stability and prevent settling. 

Here are more details on the role and placement of the pool steel framework


The pool steel framework, also known as reinforcement or rebar (short for reinforcing bar), is a critical component in the construction of a swimming pool. It provides structural support to the concrete shell of the pool and helps to prevent cracking and other structural issues. The steel reinforcement is strategically placed within the pool’s structure to enhance its strength and durability.

Role of Steel Reinforcement:

Structural Support

The primary purpose of the steel framework is to reinforce the concrete shell of the pool, adding tensile strength to complement the compressive strength of the concrete.

Preventing Cracks

By distributing and absorbing tensile forces, the steel helps to prevent cracks in the concrete. Concrete is strong in compression but relatively weak in tension, so the combination of steel and concrete creates a robust and durable structure.

Placement of Steel Reinforcement:

Grid Pattern

The steel reinforcement is typically arranged in a grid pattern within the pool’s structure. This grid consists of horizontal and vertical bars that intersect to form a mesh.

Specific Locations

The placement of the steel reinforcement is specific to the pool design and engineering requirements.

Bonding with Shotcrete or Gunite

The steel framework is installed before the application of shotcrete or gunite—the mixture of cement, sand, and water that forms the pool’s shell.

Types of Reinforcement:


Reinforcing bars, commonly known as rebar, are steel bars that come in various diameters and lengths. They are often used in the construction of pool structures.


Steel mesh, consisting of interconnected steel wires forming a grid, is another form of reinforcement. Mesh is often used in areas where it might be challenging to place individual bars.

Here are the aspects of pool plumbing installation


This essential step in pool construction involves the installation of pipes, valves, fittings, and other components necessary for proper water circulation, filtration, and drainage within the pool system. The plumbing system plays a crucial role in maintaining water quality, ensuring efficient filtration, and providing for various features such as skimmers, drains, and returns. Here are the key aspects of pool plumbing installation:

Skimmers and Main Drains

Skimmers are installed on the pool’s surface to remove debris. Main drains assist in water circulation and contribute to the efficiency of the filtration system.

Return Lines

Return lines are pipes through which filtered and treated water is returned to the pool. These lines evenly distribute clean water throughout the pool.

Pump and Filter Installation

A pool pump circulates water through the plumbing system, A pool filter, is a part the plumbing system to remove impurities from the water.

Heater and Water Features

Heater plumbing lines are installed to connect the heater to the circulation system. Water features such as waterfalls, fountains, or spa jets may also require specific plumbing installations

Valves and Manifolds

Valves are strategically placed in the plumbing system to control water flow, Manifolds are distribution points that help organize and control the flow of water.

Automatic Water Levelers

water levelers help maintain a consistent water level by automatically adding water when needed.

Backflow Prevention

Backflow prevention devices may be installed to ensure that water from the pool does not flow back into the municipal water supply.

Pressure Testing and Inspection

After the plumbing installation is complete, the system is typically pressure-tested to check for leaks.
