Installation of vinyl sheet flooring required a smooth and level surface. High levels of moisture in the concrete slabs
threatened the performance and integrity of the installation and required a vapour barrier to protect the success
and longevity of the final finish.
The removal of the existing carpeting in the building left the substrate uneven and therefore unsuitable to receive the new carpet tiles. Levelling and smoothing of the substrate prior to installation of the new floor coverings required a fast track installation, due to the tight deadlines of the refurbishment project.
LVTs require a multi-level system to deliver a well-prepared, smooth and level surface to achieve the desired aesthetic finish and to ensure the sustainability of the installation.
Moisture vapour within a concrete substrate can affect the successful installation of the final floor covering. The tolerances vary from tiles to laminates and vinyl flooring, so it is important to check with the manufacturer for the stipulated levels on the product you are installing and to measure the moisture levels within the substrate carefully.
Most flooring installers are aware that the substrate must be fully cured and have attained the moisture content stipulated by the manufacturer of the floor covering before installing the final floor covering. This is because excessive moisture in the substrate, or high moisture vapour emission rates, will most certainly result in an installation failure, for example, vinyl flooring ‘bubbling’ or delaminating from the substrate.
Underlayments are an important aspect of a flooring project, in both residential and commercial settings, where a level and smooth surface is required before installation of the final floor covering. The type of underlayment needed will depend on what kind of flooring will be installed on top of it. Other considerations include the size of the area, its purpose, and how much foot traffic it will see.
