Balcony Waterproofing

Balconies are one of the most failure-prone areas when it comes to waterproofing in residential and multi-residential buildings. They are constantly exposed to water, temperature changes, and structural movement, and even small execution errors can quickly lead to leaks and damage.

Why Balconies Often Fail

In many cases, balcony waterproofing failures are caused by:

incorrect system selection
poor execution of liquid waterproofing systems
inadequate detailing at junctions and penetrations
insufficient or incorrect drainage

As a result, remedial balcony waterproofing works are extremely common, particularly in buildings constructed in recent years.

New Construction and Remedial Works

Aquastratum delivers balcony waterproofing solutions for both new construction projects and remedial works where existing waterproofing systems have failed.

We are frequently engaged by remedial waterproofing companies to carry out sheet membrane installations where precise execution, system-based thinking, and long-term reliability are required.

Our Approach to Balcony Waterproofing

We approach every balcony as an individual technical task. Our focus is placed on:

correct selection of the membrane system
proper detailing at walls, thresholds, and door interfaces
treatment of joints and movement zones
compatibility with tiles or other final surface finishes

Our core expertise is sheet membrane waterproofing, which provides consistent and reliable results for both new and remedial balcony applications.

Typical Scope of Works

balcony and terrace waterproofing
removal of existing layers as part of remedial works
installation of sheet membrane systems
execution of junctions, seams, and details
