Some of our Subfloor Preparation methods
We carry out moisture meter readings. We check for damp using a non-invasive moisture meter test, this also tells us if the floor is dry enough to recieve a floor covering. If the reading is too high this indicates that we need to apply a DPM or MVS to the subfloor to ensure your new flooring lasts.
Mechanical Floor grinding and Sanding - The initial stage of our works on any concrete or calcium sulphate preparation.
We grind floors to remove surface contaminants, either laitance (a weak crust/ layer) formed during a new sub floor drying process or old adhesives or other contaminants, such as previous screeds are present. These contaminants are removed prior to installing new screed, DPM or Mo
MVS - Moisture Vapour Suppressant
We install Moisture Vapour Suppressant on new concrete and calcium sulphate floors if the floor is found to be above 75% RH. We carry this out after the floor has been mechanically prepared.
The main purpose of the MVS is to prevent your new floor from failing due to construction moisture weakening adhesive and screed bonds
DPM - Damp Proof Membrane
We install damp proof Membranes when there is no existing damp proof under the subfloor.
We
We screed floors for several reasons, some of which are to provide a good clean surface for your new floor to adhere to and to ensure that your floor is smooth and within the SR rating required for your new floor covering.
Screeds can either be water based or a bag and bottle. For each type we follow the same process, mix the screed, pour, apply using a pin rake and then spike roleer to aerate he
We install two different types of ply board! Which one we us depends on the floor covering chosen.
Flooring grade ply is used for our full stick flooring solutions, such as LVT and Vinyl and, exterior grade ply board for general smoothing of subfloors for carpet tile installation etc.
We either screw or ring shank nail the plyboard depending upon its thickness and all in accordance with BS8203 - The
