Underground seals for protection against constant water pressure

Do you want to prevent water ingress?

Use Roxtec seals to avoid the risk of costly downtime and power outages due to corrosion, damage to equipment or partial discharge.

More about sealing underground

Use Roxtec UG™ seals to prevent corrosion and rodents – and to maintain optimum operating conditions.

Roxtec UG™ (underground) solutions for cables and pipes protect your site against environmental ingress in both normal and flood conditions. The seals withstand cable bending forces and are resistant to constant water pressure. Keep your equipment dry and safe by ensuring a long-lasting sealing barrier against flooding, gas, humidity and rodents.

Roxtec UG™ seals resist constant water pressure

User-friendly flexibility

Roxtec UG™ seals are easy to install even in wet conditions and in environments with running water.

Available for single or multiple cables and pipes
Multidiameter™ by Roxtec – adapts to cable and pipe sizes through removable layers
Built-in spare capacity for future needs

Retention capabilities

The seals are tested and developed to provide excellent cable retention.

Catastrophic water pressure up to 1 bar (10 mH₂O)
Gas pressure up to 0.5 bar
Corrosion and rodent safe

Roxtec UG™ cable seals for underground applications.

Use the Roxtec knock-out sleeve to pre-seal openings you might want to use later on. Plan your ducted openings, with the added benefit that any spare or unused duct is sealed without additional cost. You only need to buy seals for openings that accommodate cables. This is an area efficient solution for reducing the footprint and for making sure the building is dry both during and after construction.

Include knock-out sleeves in the design work for a new building or kiosk. You decide if you want the seal on the inside or the outside and whether you want to connect sleeves into a cluster of openings. Then cast the sleeves into the structure, and knock them out when needed. Use sleeves to ensure consistent results in terms of position and formation of holes and avoid deformed ducts.

Adaptable and tailor-made solutions

Roxtec UG™ solutions are perfect for use around existing cables and pipes, and the smart design simplifies retrofit. The seals fit into the knock-out sleeve as well as in conduits and core drilled holes. The soft yet firm rubber adapts to uneven openings and ducts. Our openable seals do not suffer from failure in the same way as traditional methods do when the cables or pipes move and expand.
