Sika Liquid Plastics Roofing Solution | Tyne Tunnel South Extract
Tyne Tunnel South Extract Project Requirements:
In Newcastle, we confronted a formidable roofing task involving the replacement of a single-ply waterproofing system. Meanwhile, the Tyne Tunnel South Extract project posed distinct hurdles due to its intricate design and exacting specifications.
However, because there are many elements such as extract towers and complex handrails that intersect with the main box gutter, using single ply alone became challenging since it needed a lot of welding at the joints.
We took the roof down to its concrete base and then added a detailed system that includes a self-adhered vapor control layer and cut-to-fall insulation.
The Decothane Ultra system is a revolutionary cold-applied solution that forms a flawless, seamless waterproof layer upon curing. This system features a Decothane Ultra Base Coat strengthened with Reemat Premium glass fibre matting, finished with a Decothane Ultra Topcoat in Slate Grey. It provides excellent defence against water penetration and structural damage
A key benefit of the Decothane Ultra system is that it can be applied cold, which means no heat or open flames are needed for installation.
This improves safety during the work and allows the project to finish smoothly even while the building is still being used, reducing disruptions to your business.

Why a Liquid-Applied System Was Suitable
One of the main advantages of using a liquid-applied waterproofing system on this project was its ability to accommodate the complex geometry of the roof.
The extract towers, handrails, box gutters, penetrations, and other roof details created areas where traditional sheet membranes would require extensive cutting, joining, and welding. Liquid-applied waterproofing can instead be carefully applied around these details, creating a continuous membrane across the roof surface.
This makes liquid roofing particularly useful for refurbishment projects involving irregular shapes, difficult junctions, plant areas, penetrations, and other complex roof features.
The system also provides a practical solution for extending the performance of commercial and industrial buildings where replacing the entire roof structure may not be the most appropriate option.
Cold-Applied Roofing Installation
Another important benefit of the Decothane Ultra system is that it is cold applied. This means the system does not require open flames or hot works during installation.
The absence of open flames can provide significant safety benefits on commercial and infrastructure projects, particularly where work is being carried out around existing buildings, equipment, services, or other operational areas.
Cold-applied installation can also help simplify the working process by removing the need for flame-based application methods. This allowed DVC Roofing to carry out the waterproofing works while reducing disruption to the surrounding operation.
For occupied commercial buildings and complex infrastructure projects, minimising disruption is an important consideration when planning roofing refurbishment works.
Benefits of the Sika Liquid Plastics Roofing Solution
The completed roofing system provided the Tyne Tunnel South Extract with a durable waterproofing solution designed around the specific challenges of the building.
The seamless nature of the liquid membrane helps reduce the number of vulnerable joints across complicated roof areas, while the reinforced system provides additional strength and durability.
The main benefits included:
- Seamless waterproofing across complex roof areas
- Reduced reliance on welded joints around difficult details
- Cold-applied installation without open flames
- Reinforced waterproofing using Reemat Premium glass fibre matting
- Improved protection against water ingress
- Suitable detailing around penetrations and roof features
- Cut-to-fall insulation to support effective water management
- A durable solution for commercial and infrastructure roofing
The completed system provides long-term protection for the roof while addressing the specific challenges created by the site’s complex design.
A Specialist Solution for a Complex Roofing Project
The Tyne Tunnel South Extract project highlights the importance of selecting a roofing system based on the individual characteristics of a building rather than relying on a standard approach.
By assessing the existing roof and identifying the difficulties associated with installing another single-ply system, DVC Roofing was able to provide an alternative waterproofing solution better suited to the complex roof geometry.
The combination of a self-adhered vapour control layer, cut-to-fall insulation, reinforced Decothane Ultra waterproofing, and detailed liquid-applied finishing created a complete roofing solution designed to provide reliable protection for the building.
