Everything You Should Know About Gunite Pool Construction

In this present time and age, various pool types can upgrade your backyard’s aesthetics. One of the major types of pools is concrete pools. They are well known for their long lasting and versatile nature. But concrete can take the forms of shotcrete and gunite. The composition of shotcrete is almost similar, although their manufacturing process is different. Thinking about a gunite pool construction for your own outdoor space? Take a deeper dive and see if a gunite pool will suit your needs.

Gunite Vs. Shotcrete

Both shotcrete and gunite are forms of concrete and used to create inground pools. Occasionally, several pool firms may refer to all concrete pools as gunite pools. Thus, ensure your gunite pool contractor knows the difference between the two pools.

A full mixture of sand, cement, and water are components of shotcrete. The mixed concrete is then inserted into a piece of delivery equipment where gunite experts spray it over a rebar framework during gunite pool construction.

On the other hand, gunite is a dry mix of sand and cement with water added into it during application. In gunite, pool builders pump the dry blend into the hose, where it mixes with water at the hose’s nozzle.

Both shotcrete and gunite use a high-pressure hose during the application process. The equipment allows both materials to bond with the surface.

Pros and Cons of Gunite

The gunite pool construction process takes approximately two to three months based on the size and shape of the pool. Gunite is popular among contractors because they can stop the application process and continue with it the next day without creating cracks or uneven surfaces. The old gunite can bond with the new gunite without forming an odd look.

Contractors build gunite pools onsite, thus enabling homeowners to choose their preferred shape and design. They also have high durability and do not need a liner, minimizing maintenance procedures over the years.


Gunite pool construction takes a more extended period compared to fiberglass and vinyl liner pools.

Since the pools do not contain tiles, they can cause skin irritation and minor tears in swimming costumes. Additionally, the rough surface is a breeding ground for algae, thus lowering the pool’s health standards.

Constructing gunite pools

During a gunite pool construction process, your pool contractor will need you to select an appropriate space for your pool area. While doing this, some of the things to look out for are underground pipes, landscape, and enormous tree roots. Thus, it is advisable to select a reliable pool contractor to prevent any faults during the construction process.

After selecting the most appropriate location, your pool builder should begin excavating the area. 

When excavation is complete, your pool builder will fix strengthening structures and proceed with the plumbing process. A steel structure called rebar is then positioned over the entire pool according to your desired shape and design. The importance of the rebar is to facilitate bonding of the gunite with the surface. Gunite is then sprayed at high pressure using the hose over the rebar framework. Before drying, your builder should even it out to create a uniform surface.

Gunite Pool Construction Finishing Process

Once the gunite cures, your gunite pool contractor should start on the finishing process. Finishing incorporates plaster; plaster comes in a wide range of colors, giving you the chance to create your outdoor theme color. Finishing materials provide even surfaces to safeguard swimmers from any unnecessary accidents.

Your builder then paves the edges around the pool. They should ensure that the surface has smoothened out. The paved area could act as a patio or fireplace, depending on how you intend to decorate it.

Keep in mind that before your contractor fills your pool with water, all plumbing and electricity systems should be complete. It also applies to any extra water features like tanning ledges and waterfalls.

After the builders fill water into the pool, your contractor must test the pool’s functioning. Also, ensure he addresses all your queries and doubts before leaving. That way, you will know how best to maintain your pool.

Gunite Pool Surface & Crack Repair

Although gunite pools guarantee longevity, they are prone to cracks after some years of usage. The finishing material, the plaster will also need repair over the years. Thus, the major renovations done in gunite pools are replastering and fixing concrete cracks in the pool.

Gunite pools develop cracks due to temperature, earthquakes, shifting soils, and pressure changes. Before repairing a break, your pool builder will have to drain out your pool and eliminate any dirt. They then use tailor-made fabricated staples to grasp the cracks, thus avoiding further tear. After this, bonding chemicals act as a sealant to repair the cracks. Your gunite pool contractor will have to replaster your pool to restore an even pool look.

Occasionally, cracks are not deep enough and affect only the finishing material. In such a case, your pool will require resurfacing. Note that various pool chemicals potentially damage the plaster. So, consult your pool contractor on the most suitable compounds to use. Replastering also allows you to change your pool’s appearance since it comes in a wide array of colors.

Above all, regularly maintaining your pool is the best option of keeping your gunite pool in the best condition possible. Also, using the most suitable chemicals will boost the durability of plaster. Frequently examine your filtration system and fix any clogging problems to prevent it from malfunctioning. Ultimately, pools are expensive; so, before beginning the gunite pool construction process, consult a Southern Poolscapes professional to address all your questions.
