Mastering Waterproofing Techniques from PU Injection Grouting to Torch-On Membranes

02 Sep Mastering Waterproofing Techniques from PU Injection Grouting to Torch-On Membranes

Waterproofing is one of the most critical protection shapes of our buildings, overtaking as and breaking any form of water ingression to structures, this is very important in waterproofing to maintain buildings’ structural integrity over time. This article delves into various advanced waterproofing techniques including PU injection waterproofing, roof waterproofing, bathroom waterproofing, and torch-on waterproofing membranes, to protect your buildings from water damage.

PU Injection Waterproofing and Grouting: Tackling Challenging Areas with Precision

PU injection waterproofing and grouting adopts a high-tech solution to waterproof hard-to-reach areas. It is a type of grouting waterproofing that uses a liquid polyurethane that is injected into the cracks for the expansion and solidification of the grouting agent to fill the void, making it waterproof. The uniqueness of its solution lies in its ability to adapt and fit for complex underground openings such as the basement and tunnels; it works quite fast, yielding high hydrostatic pressure resistance capability and offers total protection for leaks where other methods fail.

The versatility of PU injection makes it ideal for addressing water ingress in challenging locations:

• Hairline cracks in concrete walls or floors.
• Leaking joints between different building materials.
• Underground structures with limited access.
• Active water leaks in foundations or basements.

Why choose PU injection waterproofing?

• Minimal disruption to existing structures.
• Ability to stop active leaks.
• Long-lasting and flexible seal.
• Can expand to fill voids and accommodate structural movement.
• Environmentally friendly (solvent-free formulations available).

This technique provides a precise and effective solution for waterproofing problems that traditional methods may struggle to address.

Roof Waterproofing: Protecting the Crown of Your Property

Roof waterproofing is crucial for a building’s overall protection, serving as the primary barrier against external moisture. Here are the various roof waterproofing methods:

Liquid-applied membranes

• Seamless application.
• Easily conforms to irregular shapes.
• Types include acrylic, polyurethane, and silicone-based coatings.

Sheet membranes

• Pre-fabricated sheets are applied to the roof surface.
• Common materials: EPDM, TPO, and PVC.
• Provides uniform thickness and strength.

Built-up roofing (BUR)

• Multiple layers of bitumen and reinforcing fabric.
• Suitable for flat or low-slope roofs.
• Highly durable but labour-intensive.

Flat roof waterproofing techniques

Single-ply membranes

• Lightweight and quick to install.
• Good for large commercial roofs.

Modified bitumen

• Combines traditional BUR with polymer-modified bitumen.
• Enhanced flexibility and strength.

Liquid rubber coatings

• Easy DIY application for small areas.
• Ideal for repairs and maintenance.

Green roof systems

• Combines waterproofing with vegetation layers.
• Provides insulation and environmental benefits.

These techniques provide seamless protection, which is crucial for preventing leaks and extending the lifespan of roof structures, thus maintaining the building’s integrity.

Wet Area Waterproofing: Safeguarding Bathrooms, Showers, and Toilets

Areas constantly exposed to water, such as bathroom waterproofing, shower waterproofing, and waterproofing toilet floors, demand robust waterproofing solutions to prevent damage and maintain hygiene. Employing sheet and liquid membranes in these areas ensures an effective and durable moisture barrier, safeguarding the property from the potential ravages of water damage.

Sheet membranes

• Pre-fabricated sheets are applied to surfaces.
• Provides consistent thickness and coverage.
• Suitable for large areas and floors.

Liquid membranes

• Brush, roller, or spray-applied.
• Seamless application, ideal for corners and joints.
• Types include polyurethane, acrylic, and cementitious.

Epoxy coatings

• Durable and chemical-resistant.
• Suitable for high-traffic areas.
• Can be decorative as well as functional.

Waterproofing toilet floors

• Apply membrane up walls to at least 150mm height.
• Ensure proper sealing around the toilet flange and pipework.
• Use flexible sealants for joints and corners.
• Consider installing a floor waste for additional drainage.

Shower waterproofing techniques

• Waterproof the entire shower area, including walls to full height.
• Pay special attention to corners, joints, and penetrations.
• Use preformed corner pieces for added protection.
• Ensure proper fall to drain for effective water runoff.

Torch On Waterproofing Membranes: A Versatile and Durable Solution

Torch-on waterproofing membranes are used for many applications since it’s a long-lasting protectors against water intrusion and is easy to use. The approach involves applying roofing bitumen sheets that fuse to the surface through heat fusion. This method is useful for roofing, balconies and other uses. In the capacity of waterproof roofing material, the torch-on membrane is used for the long-term protection of structures, especially in situations where liquid-applied membranes are not applicable.

Building Waterproofing Contractors: Expertise You Can Trust

The final cornerstone of effective waterproofing is the skilled application by professional building waterproofing contractors. This section underscores the importance of engaging experienced contractors with the necessary expertise to apply waterproofing techniques correctly. When selecting a contractor, verifying their experience and reputation is essential to guarantee the efficacy of the waterproofing measures implemented.
