Ideal for concrete structures, this method adapts to complex layouts and minor structural movements, offering a durable barrier against water infiltration.

Sheet Membranes

Sheet membranes offer a uniform waterproofing solution, especially suitable for larger balconies. Made from materials like polyethylene or vinyl, these pre-fabricated sheets provide a continuous protective layer that resists punctures. They are compatible with various substrates, including concrete and wood, efficiently covering extensive areas.

Cementitious Waterproofing

For cost-effective waterproofing, cementitious methods integrate sand, cement, and waterproofing additives. This method enhances aesthetic appeal and is easy to apply, particularly on concrete or plywood substrates. It works well in climates with minor temperature fluctuations but can be effective elsewhere too.

Polyurethane Waterproofing

Known for its flexibility, polyurethane waterproofing fills small cracks and provides a glossy, UV-resistant finish. While durable, it requires careful application to avoid moisture trapping, which can cause blistering. This method is less effective as a standalone solution but can complement other waterproofing strategies.

What Factors Should Be Considered When Choosing the Right Balcony Waterproofing Method?

Balcony repairs and waterproofing are essential investments for maintaining property value. By understanding the factors involved, you can make informed decisions and plan for potential costs.

Key Factors to Consider

When choosing the right balcony waterproofing method, it's crucial to consider:

  • Aesthetic Finish: How do you want your balcony to look? The choice of materials and methods can significantly impact the final appearance.

  • Structural Components: Assess the current condition of your balcony. Are there existing structural issues that need addressing before waterproofing?

  • Budget: Costs can vary widely based on the extent of repairs needed. Understanding these scenarios can help you budget effectively.

  • Environmental Conditions: Consider the climate and weather conditions in your area. Some systems may perform better under certain environmental stresses.

By evaluating these factors and understanding potential costs, you can make strategic decisions to ensure your balcony remains a durable and valuable part of your property.

Cost Scenarios

That’s why we have broken down the various costs around balcony repairs and waterproofing—to guide you through the likely scenarios in advance.

$36-$42 Per Sq Ft 

New waterproof system only

For balconies that are in good shape without much damage to flashing or stucco. In these cases, all they need is a new waterproof system that can be installed right over the existing system.

Less work, less material less cost.

$50-$60 Per SQ FT

New waterproofing system goes over the existing and the flashing is replaced.

In this scenario, the surface of the balcony can remain, but the flashing needs to be replaced. The stucco must be removed followed by applying the new flashing, then the waterproof system over existing surface, and job is complete.

$75-$80 Per SQ FT

Replacement of subfloor with new flashing and waterproof system.

If water has penetrated the waterproof membrane, the subfloor likely has rot or has even grow fungi. In the case, the plywood subfloor must be removed and replaced. The stucco will also have to be replaced and a new waterproof system will be installed over the new lumber.

$120-$200 Per SQ FT

Replacement of subfloor with new flashing and waterproof system.

This is the worst-case scenario! Here, there is major structural damage from water intrusion so the membrane must be replaced. In most cases the structure membrane extends 2x their span into the building living area. Engineering repair designs will need to be created by a licensed engineer.

It is the most expensive scenario and cost may vary from balcony to balcony.

 

How the Assessment Phase Influences Balcony Waterproofing Choices

The assessment phase is crucial in determining the right waterproofing system for a balcony. Here's how it shapes those decisions:

  1. Evaluating Structural Integrity:
    Experts begin by thoroughly inspecting the balcony's current condition. They look for structural integrity to ensure that it can support a waterproofing system. Any signs of instability or damage, such as cracks or mold, must be addressed to provide a sound base. If major issues are found, a complete renovation might be needed before waterproofing.

  2. Identifying Repair Needs:
    Older or damaged balconies often require repairs to the substrate. Inspectors assess if these fixes are minor or extensive. For newer constructions, repairs might be minimal, allowing for a straightforward installation of the waterproofing system.

  3. Analyzing Water Management:
    The substrate's ability to manage water is another focal point. It must be sloped correctly to prevent standing water, which could compromise the waterproofing system. Ensuring proper drainage is vital to avoid future issues.

  4. Tailoring System Selection:
    The final step is matching the building’s unique needs with an appropriate waterproofing system. The experts consider various factors—such as the material of the substrate and environmental exposure—to recommend the most effective solution.

  5. Maximizing Longevity and Value:
    By aligning the repair strategies and waterproofing options with the balcony’s existing conditions and future use, experts ensure the solution offers optimal durability and value.

The assessment phase not only guides the choice but also optimizes the performance and lifespan of the waterproofing system chosen.
