Injectable Waterproofing

What is Injectable Waterproofing?

Injectable waterproofing is a non-invasive method of sealing cracks, joints, and porous substrates from within the structure. By injecting a specialised sealant, SNSeal Injectable Waterproofing Sealant, into the core of the problem, this technique targets water ingress at its source.

Unlike traditional membranes or coatings, injectable waterproofing does not rely on surface-level coverage. Instead, it delivers a deep-penetrating, internal seal that eliminates leaks in hard-to-reach areas such as basements, lift pits, retaining walls, and car parks.

Why SNSeal is the Preferred Injectable Waterproofing Solution

At Stop & Seal, we exclusively use SNSeal Injectable Sealant for all injectable waterproofing applications. Whether the job is small-scale or a large, complex structure, SNSeal delivers consistent, high-performance results.

Engineered for challenging conditions, SNSeal is injected under high-pressure to deeply penetrate cracks and gaps, forming a robust, flexible barrier that permanently prevents water ingress.

Proven effectiveness in new and existing structures

Ideal for large-scale waterproofing projects

For both preventive and remedial applications

Expert Application By Stop & Seal Tradesmen

The Difference: Unlike traditional injection products like Foam, Resin, or Polyurethane, SNSeal stands out in several key ways:

Performs in Wet or Saturated Conditions

Can be injected into active leaks and underwater environments.

No Excavation Required

Ideal for occupied spaces or areas with limited external access.

Fast & Clean Application

Minimal disruption to operations or occupants.

Deep Penetration Where Others Fail

Thanks to its low viscosity, SNSeal is able to penetrate much deeper into cracks, crevices, and gaps compared to other injection products on the market. This ensures more thorough coverage and more effective sealing

Targeted, Precise Application

Our custom pumps ensure every injection point receives the exact amount of product needed to form an airtight seal.

Unmatched Flexibility & Adhesion

Once cured, the rubber-like consistency of SNSeal provides unprecedented flexibility and adhesion. Unlike foam or resin, SNSeal is designed to handle the natural expansion and contraction of building substrates, maintaining a tight, durable seal over time, far beyond the limitations of competing products and their warranties.

Mould & Microorganism Resistance

Developed with a high ammonia content, SNSeal actively prevents future growth of mould, fungi, and other microorganisms. This ensures that your waterproofing solution not only prevents water ingress but also protects against the growth of harmful bacteria and other contaminants.

How We Apply SNSeal High-Pressure Injectable Sealant

Our 5-Step Process ensures precision and a high-quality finish:

    1. Surface Preparation

    The targeted surface is cleaned and prepared to ensure that it is free of debris, dust, and other contaminants.

    2. Crack Identification

    The cracks and gaps in the surface are identified and evaluated to determine the best injection strategy.

    3. Hole Drilling

    A single injection hole is core drilled beside the crack to allow for the injection of the Stop & Seal waterproofing material.

    4. Injection

    The waterproofing material is injected into the cracks or gaps under pressure, filling the crack and sealing the surface.

    5. Curing

    We then spray the injected fluid with a chemical to make the Stop and Seal waterproofing “go off” and fill the crack with a solid rubber.

    Common Application Areas

    SNSeal performs exceptionally well across a wide range of structural elements:

    Z

    Podiums, Planters & Rooftops

    Ideal for sealing rooftop structures and planters prone to water leaks.

    Concrete Slabs and Roofs

    Waterproof these surfaces to fend off moisture infiltration and prevent water damage.

    Z

    Construction Joints

    Treat expansion joints that can be vulnerable to water ingress over time.

    Underground Structures

    Secure tunnels and subway stations where water ingress poses unique challenges.

    Foundation Wall Sealing

    Seal against groundwater seepage to protect foundational integrity.

    Z

    Car Parks & Ramps

    Client Reviews

    – Daniel Morgan

    We have tried many options to try and stop the leaking in our basement carpark. The boys from Stop and Seal rolled in and in a few day managed to fix a water problem we had been fighting for years.

    – Phillip Jones

    I have never seen a waterproofing solution work so well. I wouldn’t hesitate to recommend Stop and Seal to anyone with water problems.

    – Craig Nickson

    Robbie and the team at Stop and Seal are at the top of the game. They solved a water problem in our unit block that we had been dealing with forever. Now when it rains we aren’t nervous.

    Brett Cooper, Director, Tweed Ultima Apartments

    We have been caretakers of Tweed Ultima Apartments for around 2+ years, At this time we have engaged Stop and Seal to do water leak rectification on 6 or more problem areas around the property. Each leak has been assessed and whilst Stop and Seal have needed to attend to the same problem area more than once, the important thing is they have kept coming back out. All but 1 of our 6 issues have been resolved and some of these leaks have been issues over 12 years that no one else could fix. I highly recommend Stop and Seal their innovative rubber and activator and most of all their commitment to getting the job done.

    Wayne Syrch, Site Manager, Hutchinson Builders

    I have utilised the services of Stop & Seal on several occasions and have found them to be reliable, professional, and most of all, come with a can-do attitude. The SNSeal product is unique in its application, but most importantly it works, and I’ve seen great results when no one else was willing to attempt to solve an issue. I have great pleasure in recommending their services.
