Over time, ground movement and the natural ageing of materials can weaken certain parts of a swimming pool, leading to cracks, water infiltration and structural damage.

Our pool masonry services provide the foundation for a durable and long-lasting swimming pool. We carry out structural repairs to restore the integrity of the pool, reinforce weakened areas and ensure a solid base for future renovation work or the installation of a new pool finish.

How can you tell if your swimming pool has structural masonry Issues?

Certain warning signs may indicate that masonry repairs are needed, particularly if you notice:

  • Cracks in the pool walls or floor
  • Significant water loss
  • Damaged coping stones
  • A sinking or uneven pool deck
  • A deteriorating pool finish
  • Structural defects affecting the pool steps or built-in benches

It is never too early to have your swimming pool inspected. An early diagnosis can often prevent more extensive damage and reduce the cost of future repairs.

Swimming Pool Structural Modifications

Cracks, localised settlement and wall deformation are common issues that can affect swimming pools over time.

Our structural renovation work is designed to restore the integrity of the pool by repairing weakened areas and reinforcing the existing structure.

We carry out repairs to the pool walls and floor, restoring damaged sections, correcting masonry defects and strengthening structural components where necessary.

Every repair is tailored to the technical characteristics of the pool—including its structural design, the presence of steps or built-in benches, and whether it is an infinity pool—to ensure a seamless integration between the existing structure and the renovated areas.

A sound and stable structure is also essential before installing or replacing a pool finish, whether it is mosaic tiles, polyester or ceramic tiling.

Our Team's Advice

During renovation projects, we often find that structural defects are hidden beneath the existing pool finish. Carrying out a comprehensive inspection before starting any renovation work allows potential issues to be identified early, helping to avoid unexpected repairs and ensuring a more durable result.

In 2025, we completed the structural renovation of more than 30 swimming pools across Monaco and the French Riviera.

Construction and renovation of baja shelves

Adding a Baja shelf (also known as a tanning ledge or sun shelf) is one of the most popular ways to enhance both the comfort of swimmers and the overall aesthetics of a swimming pool.

This feature is particularly common in luxury private pools, five-star hotels, and high-end residential properties throughout Monaco and the French Riviera.

Our installation process

Every project begins with a detailed structural assessment of the existing pool to evaluate the feasibility of the new Baja shelf and identify any modifications required.

Our team then determines the ideal dimensions, depth and location of the shelf, taking into account swimmer circulation, the hydraulic system and the selected pool finish.

With more than 20 years of experience in swimming pool masonry, we design and build bespoke Baja shelves that integrate seamlessly with the existing pool while combining aesthetics, comfort and long-term durability.

Swimming Pool Transformation

For over 20 years, MC Piscine has been helping homeowners and luxury hotels transform existing swimming pools to better suit their needs and enhance the overall swimming experience.

Our team designs and delivers bespoke renovations, including the addition of pool steps, built-in benches, Baja shelves (sun shelves), depth modifications, and the conversion of existing pools to infinity-edge systems.

Featured Project: Family Pool Renovation in Monaco

As part of the renovation of a 15-year-old family swimming pool in Monaco, the owners wanted to improve the comfort and functionality of their pool without undertaking a complete reconstruction.

Following a detailed structural assessment, our team designed and built a built-in underwater bench and partially reshaped the pool floor to create a dedicated relaxation area.

The result was a modernised swimming pool that retained its original structure while offering greater comfort, improved usability and seamless integration with the surrounding outdoor living space.

Infinity pool repairs

Balance tank waterproofing: our repair process

The balance tank is an essential component of an infinity pool, collecting the water that continuously overflows from the main pool. Proper waterproofing is crucial to ensure the hydraulic system operates efficiently and to prevent water loss.

Over time, the balance tank may develop cracks, waterproofing failures or general deterioration due to the natural ageing of materials. These issues can lead to water infiltration, excessive water consumption and damage to the pool's hydraulic equipment.

At MC Piscine, every project begins with a comprehensive inspection of the balance tank to accurately identify the source of the problem. Our technicians then carry out the necessary repairs, including surface preparation, crack repairs and the installation of a waterproofing system tailored to the pool's construction and finish.
