Residential Waterproofing: Four Important Guidelines for Preventing Water Damage

Posted on: 18 November 2022

Waterproofing is essential for preventing water damage in residential structures. In general, moisture causes the deterioration of buildings over time. In simple terms, when water penetrates timber, concrete and other construction materials, gradual degradation will occur in the form of rotting, mould and cracking. If the problem is not addressed, the entire building will fail. Fortunately, this form of destruction can be prevented by waterproofing the vulnerable surfaces in your house. Here are some crucial tips to ensure protection against water damage. 

Repair the Structure

The effectiveness of a waterproofing membrane can be compromised by existing cracks in the structure. For instance, if a floor has a fissure, the membrane will form a gap when it cures and ages. The simple crevice will allow for water penetration and subsequent moisture damage. Therefore, you should inspect the structures you intend to protect. If there are signs of damage, like cracks and holes, seal them before proceeding with the waterproofing process.

Wash and Clean

If a waterproofing coat is applied to a dirty surface, the risk of failure will be high. The membrane will not adhere to the structure correctly due to the presence of dust and grime. Consequently, the layer could delaminate and peel, leaving the building vulnerable to water damage. Therefore, clean the area thoroughly in preparation for the work. You can sweep and vacuum most surfaces to get desirable results. If you would like to wash with water, make sure the area is completely dry before applying the coating.

Prime the Surfaces

You should use a good primer before applying a waterproofing membrane. The purpose of the primer is to improve the adhesion and durability of the protective coat. The layer is essential because some building materials are not highly receptive to the membranes. In general, it is advisable to use the primer recommended by the waterproofing manufacturer. This precaution will ensure compatibility because some primers might not work with all coats. If you are uncertain, contact your building supplies specialist.

Consider Coverage

Finally, you must ensure proper coverage of the surfaces when applying the waterproofing coat. Poor application practices will limit the protection offered by the membrane. The most critical consideration is the application rate. If you are too fast during the process, the layer might be too thin to provide a suitable moisture barrier. Check the recommended rate for delivery in the data information for the waterproofing product. Keep in mind that proper application requires experience and skill.
