Annular Space Grouting

Annular Space Grouting by Elastizell Systems

Sliplining is a trenchless pipeline rehabilitation method that restores functionality without the need for costly and disruptive trench excavation. In this process, a new carrier pipe is installed inside an existing host pipe. The space between the two pipes, known as the annular space, is filled with Elastizell Systems' Lightweight Cellular Concrete (LCC) grout. This ensures full contact, secures the liner, and provides protection against shock, corrosion, and ground movement, making the pipeline "like new" again at a fraction of the cost of full pipeline replacement.

Why Choose Elastizell Systems' Lightweight Cellular Concrete for Annular Space Grouting?

• Reduced Stress on Liner and Host Pipes: Elastizell Systems' Lightweight Cellular Concrete exerts a less buoyant force on the liner pipe, minimizing stress and preventing damage or displacement, particularly in sensitive or challenging environments.
• Long-Term Durability: Our Lightweight Cellular Concrete is designed to protect against corrosion, freeze/thaw cycles, seismic activity, and other environmental factors. This ensures the pipeline's stability and longevity, reducing future maintenance costs.
• Tailored Solutions for Every Project: We provide customized Lightweight Cellular Concrete mixes tailored to meet the specific conditions of your project. Whether you're dealing with difficult soil conditions or require a specialized mix for enhanced protection, Elastizell Systems has the solution.
• On-Site Mixing for Efficiency: Our ability to mix Lightweight Cellular Concrete on-site means fewer trucks, less traffic, and faster installation times, reducing overall costs and minimizing environmental impact. This is ideal for large-scale infrastructure projects where efficiency and minimal disruption are essential.
• Superior Flowability: Lightweight Cellular Concrete can be pumped at low pressures, allowing it to flow into and fill all voids within the annular space without damaging the liner or host pipe. This makes Elastizell Systems' Lightweight Cellular Concrete an ideal solution for difficult-to-reach or sensitive locations.
• Environmental Benefits: Lightweight Cellular Concrete is not only lightweight but also environmentally friendly. Its material efficiency, reduced transportation emissions, and incorporation of recycled content make it a sustainable option for pipeline rehabilitation.

With over six decades of expertise, Elastizell Systems continues to be the trusted choice for annular space grouting in complex infrastructure projects.
