DOYMA - Service Duct Sealing Systems for Pipes & Cables

Prevent structural damage
Wherever service ducts are installed through walls, ceilings or floors, penetrating water, other liquids or humidity may cause damage to buildings, DOYMA sealing systems ensure professional and perfect sealing, thus presenting excellent preventative measures against structural damage.

The very best in German engineering is used to seal penetration points at the wall to permanently prevent any infiltration of gases and water into the building, and the DOYMA products are guaranteed for 25 years.

With over 40 years' experience in the business we have a range of products to suit all situations for power cables, communications cables, pipes and ducts, or district heating pipes.

All too often the focus of attention is restricted to the function of the water, gas, electricity or data supply. Little attention is given to the sealing and housing of pipes and cables passing through walls and ceilings until it is too late and structural damage has already occurred.
