Answer
Condensation is the most common cause of sweating on most floors, especially in warm weather, and it accounts for the majority of cases. Wetness occurs when warm humid air from the outside comes into contact with cold concrete because the air rapidly cools and condenses on the surface, causing it to become wet.
How do you keep condensation from forming on laminate floors is another question.
Changing the Insulation on the Outside Add a layer of insulation to the exterior of your home, particularly around the rooms where you have installed a laminate floor, and you may be able to alter the pressure and moisture levels in the room enough to prevent condensation from forming.

Air movement can help to dry out the room; a high-volume, low-speed fan works well for this.
Reduce the air conditioning/increase the heat to maintain a consistent temperature between the concrete floor and the surrounding air.
Dehumidifiers can be used to remove moisture from the air and reduce the amount of condensation.
In a similar vein, you might wonder if laminate flooring can cause dampness.
The underlayment for laminate flooring is made up of a thin plastic sheet that extends from the concrete floor all the way up to the skirting board and back. The damp is concentrated in the lower part of the walls (the first couple of feet) and is particularly bad in the skirting boards. The damp is completely gone (some of which have completely rotted).
What is causing the bubbles in my laminate flooring?
A build-up of moisture beneath laminate flooring or an excessive amount of tension between the planks can both cause bubbles to appear on laminate flooring. Take a walk around your laminate floor to check for bubbles in the areas where you can feel them.

What is the best way to remove the musty smell from laminate floors?
In a large bucket, combine equal parts water, rubbing alcohol, and white vinegar. In addition to having antimicrobial properties, vinegar and rubbing alcohol can both be used to kill mould spores on laminate floors. In addition, the alcohol aids in the rapid evaporation of liquids, which helps to prevent damage or warping of the laminate’s surface from occurring.
Is it possible for damp to rise through concrete?
When a damp proof membrane fails or is not installed prior to the floor being laid, it is fairly common for water to seep through the concrete floor slabs. When you have damp issues with carpets and floor coverings, as well as warping of wooden floors, you are in this category.
Is it necessary to use a damp proof membrane under my laminate flooring?
There will always be moisture in your floor, no matter how dry it appears to be. This moisture will be drawn to the wood if it is not treated, resulting in cupping, lifting, and general damage to the floor. When installing engineered flooring, use a plastic membrane sheet with a thickness greater than 0.2mm. It is recommended that you use a two-part liquid damp proof membrane for solid floors.
Is it necessary to seal a concrete floor prior to laying laminate flooring?
You don’t need to seal a concrete floor before installing laminate; however, to prevent moisture from the concrete floor from affecting your laminate, install a vapour barrier of polyethylene film. Install this barrier even if the concrete subfloor is covered by vinyl, linoleum, terrazzo or ceramic tile.
Does laminate flooring need to breathe?
The installation of your laminate flooring is the critical time to think about humidity. Give them room to breathe and become used to the humidity level in your home. The full acclimatisation process takes 48 hours. After your flooring has sat at least two days, you’re ready to install.
Does humidity affect laminate flooring?
Similar to hardwood flooring, laminate flooring will swell up if exposed to extensive humidity levels, which can create an uneven flooring surface. However, unlike wood, it will also contract if it is exposed to extremely low levels of humidity, which can expose gaps between individual flooring tiles and boards.
How do I seal a damp concrete floor?
Seal the Floor Use a sealer designed for concrete moisture protection, such as an epoxy concrete sealer, which often comes in two parts that must be mixed immediately before applying. Pay special attention to the corners and edges of the floor, where cracks can let extra moisture seep in.
How do I know if my laminate floor is mouldy?
3 signs of mould under hardwood floors 1- Musty smells. Musty odours permeating your home environment can be a clue that a mould issue is affecting your home. 2- Water damage. 3- Check under the hardwood floorboards. Option #1: Do it yourself. Option #2: Hire a mould remediation specialist.
Why is my floor sweating?
Condensation is the most common cause of sweating on most floors, especially in warm weather, and it accounts for the majority of cases. Other causes for sweating floors is lack of moisture barriers beneath the slab hence the movement of moisture from underneath to the surface.
Why is my floor always wet?
There are two main reasons for damp floors — a humid room or water below the home. A quick inspection below the floor and adjustments to the home’s air can significantly reduce the phenomena. If dampness reappears, you may need to contact a plumber to check for leaking water pipes in your floors or walls.
Why would water come up through the floor?
Common causes are leaks in the ceiling or a crack in the exterior of the home which both permit water to enter. If the water is seeping up through the floor, it could be a result of insufficiently-sealed foundations or there could be cracks in the foundation floor.
How do I stop moisture in my concrete floor?
Methods Used to Stop Moisture in Concrete Floors Low-permeance Vapor Barrier or Retarder. A Low-permeance vapour Barrier or retarder can effectively keep below-slab moisture from reaching the flooring system. Allow Natural Drying of Concrete Slab. Keep Excavation Free of Water.
Should I put plastic under my concrete slab?
Vapor retarders have been used since the 1950s. Recently, though, research has shown that the old traditional layer of 6-mil Visqueen (polyethylene plastic) under the slab is seldom effective for two main reasons: Although it may seem water-tight, this grade of material allows a lot of water vapour to pass through.
Why is my concrete floor wet?
There are a couple of reasons why your garage floor may be getting wet. The most common is condensation — AKA sweating garage floor. When relatively warm, moist air comes in contact with a very cool concrete slab, the cold temperature of the concrete will cause the air that comes in contact with it to cool.
