Our Story
Great Things Take Time
Years of Development and Testing

As many district heating pipe systems have reached an age where corrosion begins to impair the system and leaks occur, replacement is needed. This has previously been a difficult and costly operation involving extensive excavation.
Minimizing or completely eliminating the excavation process when replacing district heating pipes requires a new relining solution. To date, no product has been able to withstand the harsh conditions of the district heating system — until PPR developed CarboSeal.
After years of development and testing, which commenced in 2010, PPR has created CarboSeal — a relining solution that withstands the high-heat, high-pressure corrosive environment in and around district heating pipes.
