Permanent Waterproofing Repairs to Leaking Roof with Robust Membranes

  • Using a FLEXIBLE and SEAMLESS spray-applied Liquid Rubber membrane, our Team can repair leaking & failed sheet/torch on membranes without the cost of a complete re-installation.
  • In many cases with this system it is possible to completely over coat the existing roof surface with a fast spray application.

Torch On and traditional sheet membranes have a tendency to leak at split seams.

  • Sheet/roll on membranes have a high tendency to leak at the joins which are often either heat or chemically welded.
  • These seams are liable to break and/or deteriorate under temperature and cyclic movement.
    Sheet membranes are not fully adhered and bonded to the substrate surface.
  • Once water enters the membrane, the entire area can become water logged underneath the sheet membrane.
  • This water can then travel a great distance from the original entry point.
