When you are planning a build, it is easy to forget the hidden details, like cable ducts and fire resistance, that make sure your building stands the test of time. Correct installation and making sure you use the appropriate products can help keep the buildings cables and pipes accessible. And if any cables need removing in the future, making any maintenance easier to complete with little disruption in the process. Pipe sealing systems also prevent structural damage. Wherever service ducts are installed through walls, ceilings or floors, penetrating water, other liquids or humidity may cause damage to buildings. 

We use the very best in German engineering to seal penetration points through walls and floors to permanently prevent any infiltration of gases and water into the building, thus presenting excellent preventative measures against structural damage. They will meet all your watertight duct sealing requirements. Distributing the industry’s best manufacturers, Service Sealing Solutions offer the most extensive range.

Service Sealing Solutions provide a number of different service sealing solutions across the UK to both the public and private sector, making them the ideal choice for your next project.
