Using our epros® Top Hat System with silicate resins we can repair connections directly from the main sewer. This permanently seals them and it is WRC approved. We use these resin systems specifically for lateral connection and short repairs. They are also easy to handle, so we can install them quickly. And they are known for their good mechanical properties and chemical resistance when cured. The patented two-component resin mixture consists of a resin and hardener. McBreen Environmental operatives are fully trained in application of this system to ensure a trouble free long life span.


  • Cured at ambient temperature within about 1 to 3 hours (we control and adjust cure times as necessary)
  • Excellent performance both at extreme temperatures – high and low
  • Very good resistance to harsh chemicals, acids and caustics (pH 1 – 13.5) after final cure
  • High temperature resistance of short/CIPP liner after final cure
  • No volatile organic compounds (styrene free)
  • Excellent adhesion to many pipe materials like vitrified clay, plastic, steel etc. with a close frictional and positive fit to HDPE pipes
  • Virtually no shrinkage (<0.6%)
  • We use them at a wide range of ambient temperatures
  • Excellent performance both at extremely high and at extremely low temperatures
  • Expected service life of more than 50 years as proven by 10,000-hour test
  • The cured resin is self-extinguishing and we can thus use it in critical areas such as airports and tunnels
  • Tested by independent bodies (IKT – Gelsenkirchen, WRc UK) in compliance with international standards such as DIBt, ASTM, WIS and DIN EN
