Application

  • Suitable for both wall and floor applications when used in a PUDLO Cavity Drain System (Type C) installation.
  • Can also be used in floors, liner walls, vaults and tunnels, both above and below ground level and in other waterproofing applications – consult manufacturer for details.
  • Predominantly for concrete surfaces, but non-concrete surfaces can be used.
  • Should not be used in applications where hydrostatic pressure resides as a single system. Further, flat soffits should never be lined with PUDLO CD20 as it requires a minimum slope of 10%. To achieve a Grade 3 habitable environment in accordance with BS 8102:2022, ensure adequate ventilation/ de-humidification or air conditioning is designed and installed accordingly.
