Protecting Waterproofing Membranes

Protecting Basement Waterproofing Membranes

How to fix leaking waterproof membranes damaged during construction?

I don’t know how many times I have seen our carefully installed membranes trashed by subsequent trades or carelessness during construction.

Findlay-Evans Waterproofing – Certified Liquid Rubber applicators based in Melbourne

  • We offer various solutions to failed existing sheet membranes that are leaking at joins and seams but otherwise are intact.
  • Our Team can overcoat these existing membranes with a spray application of liquid waterproofing coatings that will firmly adhere to the surface. This provides a fully bonded seamless waterproof system over the existing failed membrane.
  • We can offer repairs to existing membranes that are leaking, deteriorated, cracked and aging.
  • Using a cold spray application, Liquid Rubber membranes can over coat an existing roof – repairs that are Cost Effective & Save Time.

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 waterlogged underneath the sheet membrane.
  • This water can then travel a great distance from the original entry point.
