Sub-Floor VS Above-Floor Interior Waterproofing Systems

Sub-Floor VS Above-Floor Interior Waterproofing Systems

Maintaining your home’s curb appeal and overall condition is important not only because it helps you maintain its value but also for the very simple reason that it’s your home. One of the best ways of achieving this is by ensuring that your home has the appropriate waterproofing measures in place. Depending on your needs, you can either go for a sub-floor waterproofing system or an above-floor waterproofing system. But what is the difference? Let’s find out.

Above-floor waterproofing system


An above-floor waterproofing system is essentially the first line of defense against water. As the name suggests, this type of waterproofing system is placed above ground, which gives it an edge over a sub-floor waterproofing system. In particular, given that the system is not submerged in soil, you are unlikely to experience fewer blockages, a common problem experienced with sub-floor systems. The system is non-invasive since there’s no digging. Water in this system is collected along the joints between the floor and wall.

Sub-floor waterproofing system


A sub-floor waterproofing system is quite extensive and effective at managing water seepages. It entails applying membranes and coatings at the foundation level of the structure to safeguard the basement from seepages. Sub-floor waterproofing systems help manage water leaks from your basement walls, footer, and foundation faults. As such, it’s a great way of relieving hydrostatic pressure and lowering the water table around your home.
Which one should you choose?


Installing both waterproofing systems isn’t the worst idea in the world – you can never have too much interior waterproofing and exterior waterproofing for your home. However, if you can only pick one method, a sub-floor waterproofing system can easily solve all your water management system. This method is especially appropriate when your house has a basement, since compared to the above-floor waterproofing system, it targets more consequential water sources such as the foundation walls.
