Damp Proofing a Concrete Floor

About Damp and Concrete Floors

Discovering damp or moisture within your concrete floor can cause stress. As concrete floors are particularly susceptible to rising damp, it is important to put a process in place which prevents this from happening. As concrete is a porous material, moisture can travel through to above flooring with ease.

There are considered to be two main solutions to damp concrete floors, including:

• Digging up the flooring and installing a damp proof membrane
• Isolating the dampness using DPM (Damp Proof Membrane)

How To Deal With Damp

All concrete flooring should have a damp proof membrane already installed. However, if you live in an older property, chances are this was never fitted. In a new property, you should be able to improve on your damp proof course. Alternatively, a substance known as epoxy resin coating will be applied.

Epoxy Resin Installation

One of the first steps to take should always be to clean the floor. Removing dirt and mildew build-up helps to remove any damage, making sure it is safe to be treated. Mould and insects often tend to be present in corners, which is why attention should be placed here. If you need deeper cleaning than bleach, you should use a rotary floor scrubber to help lift any unwanted grime.

Once clean, the concrete flooring should then be dried. A dehumidifier is the best option for drawing out water as it helps to circulate warm air, speeding up the process.

After these steps are completed then a sealant will need to be applied. Often a tricky process to undertake, you should always consult a professional.

Adding Membrane To Flooring

Whether you have a new floor or would like to upgrade an existing flooring, then adding a thin layer of membrane may be a good solution. Membrane can help to isolate the concrete from any flooring that is added above it, preventing damp and moisture.

Some of the major advantages of membrane include:

• Simple and Fast to Install
• Enhances Thermal and Acoustic Performance
• Allows Finishes to be Applied Whilst Drying Out

What Are Cavity Drainage Systems?

Better suited for cellars and basements, a cavity drainage system helps to manage water ingress.  These systems protect the areas using membranes, drainage channels and a sump chamber and pump system.

It works by channelling water into a safe place to exit the building, rather than via the concrete flooring. As a permeable surface, it is important to prevent moisture from reaching this point.

A professional will work with you to install this system if required. Each basement is different and the solution suggested will vary depending on this.
