Often the life cycle of a waterproofing membrane or roof is reached or the system fails due to various problems with the substrates or application. When this happens a new waterproofing system needs to be applied to continue protection from moisture ingress. Re-waterproofing a substrate has its fair share of difficulties, among these are having to remove tiles and screeds in order to apply another waterproofing solution. Waterproofing that is exposed poses less hassle in being replaced than waterproofing in covered situations. In re-roofing a roof repair can easily be affected if the condition of the roof is not severely compromised. Where serious damage to roofing is present the roofing sheets must be replaced to restore the roofs functionality.

New Waterproofing on existing buildings

Clients often ask whether a waterproofing contractor can apply something over the existing membrane or over the existing tiles in the case of a balcony. Many factors prevent this from happening e.g. a waterproofing contractor will rather not apply a waterproofing product over an existing waterproofing product because he is essentially applying a solution on a failed system. He would prefer removing the old waterproofing and applying his product on a suitable substrate, thus making him responsible for his guarantee. Applying waterproofing over tiles on a balcony if a failed system is already in place below it can be disastrous since the contractor can trap latent water between waterproofing systems. This can cause structural damage to substrates. Waterproofing contractors on the whole prefer to go back to the underlying substrate and waterproof at that level.

Flood Testing Waterproofing

Flood testing is a method used by waterproofing contractors to check if the system has been applied properly and that there are no defects. This is particularly helpful to clients who want to be assured that their leaking roof or balcony has been properly repaired. After re-waterproofing a client may insist on a flood test to give them extra peace of mind.
