A common request we encounter is the replacement of waterproofing membranes and treatment of the resultant water damage which is commonly seen in shower recesses and external balconies. Rectification of failed membranes can be very costly, with tiles and sheeting often needing to be removed, and possibly any further damage to flooring, framing, or joists needing to be rectified.
The initial issue may be proper preparation of the surface being waterproofed. Poor preparation can be due to lack of time – there may be insufficient time allowed for the correct surface preparation prior to application of the waterproofing membrane. Performance of the membrane can fail or be greatly affected when it is left to the last minute, especially with joints and junctions.
Poor workmanship, including incorrect or uneven installation, as well as the wrong product or methods used can lead to leakage issues. Poor preparation and installation of critical junction points in vertical and horizontal surfaces is a major cause of failures since poor detailing and inadequate curing of the bonding solution can adversely affect a membrane’s effectiveness. This can cause the membrane to shift and crack due to differential movement occurring over time.
Surfaces must be smooth, clean, and free from any debris or distortions. Optimum performance of waterproofing membranes is guaranteed when the manufacturer’s recommended methods for application are used.
There are many options for waterproofing membranes which are suited to specific environments or applications – attention to detail and experience with products and substrates is essential.
