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.

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.

The Process

How We Apply SNSeal High-Pressure Injectable Sealant

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

Surface preparation

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

1

Crack identification

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

2

Injection hole drilling

A single Injection hole is core drilledbeside the crack to allow for the injection of the Stop and Sealwaterproofing material.

3

Injection

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

4

Cure time

We then spray the injected fluid with a chemical tomake the Stop and Seal waterproofing “go off” and fill the crackwith a solid rubber.Injectable waterproofing may be required when a structure.

FAQS

Have Questions

We’ve heard it all. Here’s everything you need to know before working with us.

Injectable waterproofing can be used on structures at any stage of construction, though it’s most commonly applied to existing buildings as a remedial solution. It’s often recommended for structures showing signs of water damage or leaks, such as wall cracks, construction joints, or pipe penetrations.
For existing structures, the process can be more complex, as Stop and Seal may need to remove materials or make modifications to inject the waterproofing into areas like basement walls, floor slabs, or lift pits.

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.

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.
