When standard products and conventional methods fail, complex cable entries need more than an off-the-shelf recommendation.
In Llandudno, a client faced a difficult cable entry sealing challenge involving multiple cable penetrations passing through an external wall before continuing underground. Several companies had already assessed the installation and reached the same conclusion: the entry could not be effectively sealed.
Rather than walking away, FILOform worked with one of our approved installers to develop a bespoke cable sealing solution designed to provide reliable, long-term protection against water ingress.
The challenge: sealing multiple cable penetrations through an external wall
This project involved a complex arrangement of cable penetrations entering through an external wall and continuing below ground level. The layout created a challenging sealing application where a durable barrier was needed to help prevent water ingress while still allowing for future cable access if required.
Because no standard method was suitable, the project required a tailored approach based on the exact (complex) cable entry configuration.
Some of the most challenging cable sealing projects do not need an off-the-shelf answer — they need a partner with the expertise to develop and deliver a complete turnkey solution. That is exactly what FILOform provided here, turning a difficult installation that others could not resolve into a fully sealed, re-enterable system designed for long-term performance.
The solution: a bespoke sealing approach using FILOseal+ HD
To overcome the installation constraints, FILOform’s technical team worked closely with the approved installer to develop a practical cable penetration sealing solution.
Following detailed technical discussions, the agreed approach used FILOseal+ HD — our high-performance, re-enterable sealing compound — to seal each cable penetration while accommodating the unique layout of the entry.
Our bespoke services delivered the flexibility needed for a non-standard installation while helping to create a dependable seal against all manner of ingress.
The result: a sealed cable entry approved by the client
The bespoke solution was successfully installed and approved by the client. Our client was delighted that a viable sealing method had finally been found after multiple previous attempts to source a solution had been unsuccessful.
The completed installation:
- Provided a fully sealed cable entry designed to help protect the building against ingress
- Delivered a durable, re-enterable seal to support future cable maintenance or upgrades
Technical support matters in complex cable sealing projects. Every cable entry presents different sealing challenges, particularly where external wall penetrations, underground cable routes and irregular layouts are involved.
That is why effective cable entry sealing solutions depend not only on the product itself, but also on the technical expertise behind it. By combining the versatility of FILOseal+ HD with the knowledge of our technical specialists and approved installer network, FILOform was able to develop a solution where others had seen an impossible seal.
