What Is Concrete Injection?
Concrete injection (also known as crack / joint injection) is a process where resin (usually polyurethane, sometimes acrylate or hybrid) is injected under pressure into cracks, joints, voids or penetrations in concrete or brickwork that are leaking or prone to leaks. The resin expands and cures to form an impermeable, flexible seal behind or within the structure. This method can stop leaks in minutes in many cases.

Standards, Certifications & Performance Guarantees
We use resins/systems that comply with European standards such as EN 1504-5 (for structural repair via injection) and carry relevant CE marking. (When applicable, solutions from established suppliers like Sika, S1E etc.)
Our methods ensure long-term durability, resistance to hydrostatic pressure, and movement.
All works carried out by trained/certified technicians, with quality-controlled application, site safety and method statements.

What Influences Cost & Timeline
Severity and number of leaks/cracks.
Size, depth, and accessibility of the structure.
Water ingress (static vs flowing water) / hydrostatic pressure.
Type of resin needed (foaming, hydrophobic, flexible, etc.).
Surface preparation and site conditions (e.g. needing to remove concrete spalls, cleaning, safety).
Travel/logistics for site location.

Frequently Asked Questions
How quickly does concrete injection seal a leak?
In many cases, leaks can be sealed within minutes once the polyurethane resin is injected and contacts water. Full curing might take additional time depending on resin type and environmental conditions.
Is this method permanent? Will I have to redo it?
Yes, when the correct resin is selected and applied properly, injection provides a long-term seal that resists movement and water pressure. However, extreme structural damage may require additional repairs.
What types of cracks or leaks can be treated with injection?
Cracks, joints, and penetrations in concrete or brick structures
Hairline seepage and large leaks
Active water flow under hydrostatic pressure
Voids behind concrete surfaces (honeycombing, poorly compacted concrete)
Are there standards/certifications I should look for?
Yes. For structural repair via injection, EN 1504-5 is a key standard. CE marking, quality data sheets from resin manufacturers (Sika, S1E, etc.) are also important.
Will this service disrupt operations?
Minimal disruption. Because the method is non-invasive (no large excavation) and often can be done from outside or with minimal access, downtime is usually limited. We plan to minimise the impact on your operations.
