The following 'site visit report/product specification' was put together for my client who has had to take over a job from a previous builder due to one reason or another.
The job was supposed to be completed in February 2017 but due to a change in builder is now due to be completed by June 2017.
The home owner has to move in by the end of July 2017.
My client had the following requests from the homeowner...

Site Visit Results
Area: 270sqm
(3 levels. Entrance area 45sqm/Kitchen 125sqm/Lower section 100sqm)
Concrete
Sub-floor Moisture level: Building has
not been sealed as of 18/04/17. No readings available
General Humidity
level: Building has not been sealed as of 18/04/17.
No readings available
Level 1
Entrance Area
Sub-floor in
a sound condition. Initial inspection shows the concrete floor to be dry (Moisture
reading should be taken when building is sealed)
Electric UFH
to be installed with thermal insulation boards.
Level 2
Kitchen
Sub-floor in
a sound condition. Initial inspection shows the concrete to be dry (Moisture
reading should be taken when building is sealed)
Polypipe UFH
to be installed.
Engineered
wood flooring to be installed.
Depending on
which Polypipe system is used depends on the installation process…
Polypipe Overlay – Wood flooring can be a ‘floating
floor’ or fixed to the overlay board with screws or fixed with adhesive when
Overlay boards are sealed with a suitable floor primer (see product spec)
Polypipe Overlay Lite – Wood flooring to be installed on a
‘floating floor’ method.
Level 3 Lower
Section
Sub-floor in
sound condition. Initial inspection shows the concrete to be wet (Moisture
reading should be taken when building is sealed)
Polypipe UFH
to be installed.
Engineered
wood flooring to be installed.
Overall
length exceeds 10m (14.5m) and would require a break in the floor due to
expansion.

Product Recommendations
Sub-floor
Preparation
- All concrete sub-floor to be sealed with a Surface
Damp Proof Membrane. Due to the excess of moisture in the Lower Section
and unable to detect a suitable Structural Damp Proof Membrane throughout
the rest of the floor area it would be recommended to seal the whole floor
area prior to the installation of any type of floor covering.
Products
suitable: FBall F77 or similar
- Please check manufacturers’ recommendations when
applying adhesives. Priming might be needed.
Products
suitable FBall P131 or similar
Real Wood
flooring
- Due to the timescale for installation, the majority of real wood
flooring would not be suitable for installation for at least 6 months due
to the moisture and humidity levels within the building. The building had
not been sealed which therefore means the wet/dry products such as
concrete/plaster have not had the ability to ‘sponge dry’. Concrete/plaster
soak up moisture at cool temperatures (evenings/winter) and then release
the moisture when temperatures raise (daytime/summer) This sponge effect
drying can continue for approx 12 months depending on the material. Speed
drying is not recommended as this can cause shrinkage/cracking
Products
Suitable: Meister Wood Flooring with Aquasafe HDF Core
Meister Lindura / Meister Residence
Parquett (Herringbone Design)
Meister
Lindura/Residence are manufactured using a moisture tolerant HDF core which
allows the product to be installed in rooms with 30 – 65% relative humidity at
a room temperature of 18 – 22 degrees Celsius. Most engineered wood flooring
have a soft wood/multi-ply core which only tolerates up to 30 - 45% relative
humidity at a room temperature of 18 – 22 degrees Celsius.
Meister
HDF core products can be installed up to a maximum of 10m (length/width) before
an expansion break is needed.
In conclusion
to my findings I would recommend the following products to be installed.
Level 1 Entrance
Area
Meister wood
flooring with HDF core installed on a Low TOG wood flooring underlay with
integrated PE film.
Level 2
Kitchen
Meister wood
flooring with HDF core (Lindura/Residence). Glued down installation preferred
but ‘floating floor’ would be adequate. If floated a Low TOG wood flooring underlay
with integrated PE film is required.
Meister
composite HDF (Catega Flex) 100% waterproof. Wood and Tile effect
available.
Level 3 Lower
Section
Meister wood
flooring with HDF core (Lindura/Residence). Glued down installation preferred
but ‘floating floor’ would be adequate. If floated a Low TOG wood flooring
underlay with integrated PE film is required.
Meister
composite HDF (Catega Flex) 100% waterproof. Wood and Tile effect available.
Note: Due to
the Lower Section room length exceeding 10m there would need to be a break in
the floor due to expansion. If a carpet was installed in the ‘Lounge’ area of
the lower section then this would reduce the length to under 10m and there will
be no need for an expansion break.
There are
many other products available which would also be suitable but I have only
recommended products which suit the specification given.
