Basement Waterproofing: How Cavity Drain Membrane System (CDM) Works

Press Release: February 05, 2021

When you waterproof your underground space, you’re not only increasing the value of your home — you’re making it a healthier space to live in. Because when not properly addressed, water damage can lead to mold growth and poorer indoor air quality. When you hire a basement waterproofing service, you’ll learn that one of the waterproofing systems they use is the so-called Cavity Drain Membrane (CDM) System.

In this article, we’re discussing how CDM works.

How The CDM Waterproofing System Works

Traditionally, damp specialist service Kent waterproofs a basement through conventional tanking. In a nutshell, the goal of this method is to hold back the water and pressure and prevent them from penetrating the underground structure.

The CDM system, on the other hand, allows water to seep into the walls. Water damage is prevented through the presence of an air gap between the wall and the installed cavity drainage membrane.

The cuspated membrane — which can be applied to the walls and the flooring system — prompts water to be filtered down to a slab and flow into a certain perimeter channel, which then directs the water into a sump pump. The sump pump is typically installed below the slab.

To accommodate larger volumes of water, the floor membrane of this waterproofing system should have a thicker stud compared to that of the wall membrane’s. Typically, the floor membrane uses a stud with 20-mm thickness, while their wall counterpart only has 8-mm thickness.

The CDM system is generally used for existing underground structures that need waterproofing and won’t be subjected to any other structural alterations.

CDM System: What Are Its Advantages

Many businesses that provide damp specialist service Kent recommend the CDM system because of the drain membranes’ versatility and flexibility. They are easy to install — whether the existing basement wall is concrete, brickwork, or blockwork.

As much as the membranes are easy to install, they are also easy to repair. Therefore, you won’t have to stress yourself out over costly maintenance issues.

Compared with conventional waterproofing methods, this technique also prevents pressure from building up against the wall — which means you can be confident that your basement’s structural integrity will remain intact.

While this system offers many perks, take note that these advantages will only be attained if the waterproofing is done by an experienced professional. Proper measurements and thorough installations and inspections are needed to ensure that the system will work properly and optimally.
