WATERPROOFING &
WATER TIGHTNESS

Stop water in its tracks. Protect your building now—and for decades to come.

Why
Waterproofing
Matters

Waterproofing a façade—often referred to as the building envelope—is essential for preventing water ingress, extending the life of the structure, and supporting energy efficiency by keeping internal systems running optimally. When water finds its way in, it doesn't just cause cosmetic damage—it compromises structure, safety, and value.

Understanding the
Building Envelope

The building envelope includes all components that separate internal and external environments: façades, roofs, windows, doors, and joints. When sealed and detailed correctly, this envelope becomes the building's first and most critical layer of defence against moisture, weather, and heat loss.

Key Components of an Effective Waterproofing System

Membranes: Primary barrier preventing water entry into structural materials.

Sealants: Fill joints and material transitions for a continuous, watertight seal.

Flashings: Redirect water away from vulnerable areas like wall-roof junctions.

Drainage Systems: Channel water away from walls, foundations, and substrates.

Common Types of Concrete Waterproofing

Cementitious Waterproofing

Durable and easy to apply, ideal for foundations and wet areas.

Liquid Membrane Waterproofing

UV-resistant, seamless coating for terraces and roofs.

Polyurethane
Membrane

Highly flexible, durable, and resistant to extreme weather.

1.

The process begins with a thorough clean, followed by the repair of any visible damage and smoothing of rough or uneven surfaces of the concrete roof.

2.

Application of concrete patching compound or engineered screed.

3.

Rubber waterproofing tape is installed along all edges and around existing roof structures to ensure a smooth base surface.

4.

Application of primer to enhance the adhesion of the waterproofing material.

5.

Application of waterproofing product following the manufacturer’s instructions.

Step-by-Step Waterproofing
& Water Ingress Solution

OUR

Step 1

Façade Audit
& Assessment:

Using SkyGrid™ and SkyScope360™, we map the building envelope and identify areas of water ingress, joint failure, and structural risk.

Step 2

Access Strategy
& Scope Definition:

We plan all works using MARS™ and PEARS®, ensuring safe, scaffold-free access to even the most difficult-to-reach areas.

Step 3

Targeted
Remedial Works:

Our rope access specialists apply membranes, reseal joints, and implement waterstop systems with precision.

Step 4

Quality Assurance
& Testing:

Every treatment is tested and logged in our SE2EPC® system, with photographic evidence and QA records stored securely.

Step 5

Preservation
& AfterCare:

With optional AssetCare™ plans, we support routine inspections, future sealing, and warranty-backed peace of mind.

Project Highlight:

The restoration of two iconic residential towers in Bondi, located above a busy commercial precinct, presented significant access and logistical challenges. To minimise disruption to residents and the surrounding community, CPR deployed our PEARS@ system, allowing us to work quietly, avoid street closures, and compress the project timeline.

Scope of Works:

Full façade cleaning and preparation

Brick mortar repointing and Helifix bar installation

Structural repairs completed and façade modernised.

Significant asset value uplift with a fully waterproofed building

FAQs

What’s the process for applying concrete waterproofing?

1. Surface Preparation
2. Selecting the Right Waterproofing System
3. Application
4. Curing & Drying
5. Quality Control
6. Maintenance, Documentation & Reporting

Are there eco-friendly options for waterproofing?

Yes. We use low-VOC coatings and systems that improve the concrete’s natural resistance without harmful additives.

Can you access hard-to-reach façade areas?

Absolutely. All works are scaffold-free using advanced rope access systems
