The Proven "No Dig" Solution for Pipeline Integrity.
Over 50 Years of Trusted Performance.
Internal mechanical seals have been a proven "No Dig" Solution for pipeline integrity for over half a century. As a cost effective, trenchless solution, they offer a reliable method to combat pipeline leakage without the need for disruptive excavation.
- Proven track record in water, industrial and gas sectors.
- Water industry approved materials compliant with BS6920.
- Life expectancy of 100+ years.
Versatile and Durable Seals.
Seals are available in multiple rubber grades, making them adaptable to a wide range of pipeline environments. Whether you're dealing with potable water or industrial fluids, there's a seal to match.
-
Suitable for pipe diameters up to 3500mm
-
Compatible with concrete, steel, ductile iron and GRP substrates
-
Handles potable, cooling, industrial, raw and waste water as well as fuels and gas
-
Flexible seal designed to move in elongation and articulation to cope with pipe movement after installation.
Minimal Excavation, Maximum Efficiency.
Depending on pipe diameter, access is only required every 150 - 400 meters, reducing surface disruption and signficantly reducing carbon footprints when compared to traditional leakage solutions.
-
Confined space installation by certified Gravitas teams.
-
In-house rescue support for enhanced safety.
-
Quick & efficient installation process.
-
Reduced supply interruptions & operational downtime.
High Pressure Sealing Performance
Seals are secured using stainless steel retaining bands, capable of withstanding:
- Up to 20 bar internal pressure
- Up to 2.5 bar external pressure
Custom Solutions for Complex Challenges
For longitudinal cracks, significant pipe damage or chemically aggressive environments, we offer bespoke sealing systems.
-
Structural stainless steel sectional liners tailored to pipe geometry
-
Seals that will join together in 430mm sections for extended sealing areas
-
Permanent end seals for CIPP and close-fit liners to prevent water tracking
Flexible Across All Pipe Configurations
Mechanical seals are engineered to adapt to a variety of situations. Their permanent elasticity ensures a secure seal, even if the pipe shifts after installation.
-
Horizontal, vertical and steep gradient systems.
-
Round and non-circular pipe profiles.
-
Pressurised and non-pressurised environments.
-
Pipe joint movement post installation.
