Regency Construction are pleased to offer the following flooring services:
Floor screeding involves providing a level and smooth surface for floor coverings.
There are several types of sand and cement screed; bonded, unbonded and floating.
Bonded screed is laid directly onto a pre-laid concrete base. The surface of the floor is grouted before the screed is laid. It is recommended that the thickness of a bonded screed should be between 25 and 40 mm.
As the name suggests, unbonded screed is not bonded to the concrete base. It is sometimes laid on top of a new damp proof membrane. It is recommended that the thickness of a unbonded screed should be between 50 and 70 mm.
Floating screed is used on top of rigid insulation boards. It is recommended that the thickness of a floating screed should be between 65 and 90 mm.
The sand and cement floor screed can be combined with man-made fibres can be added to increase its strength. Small quantities of screed can be mixed on site, for larger areas ready-mixed screeds can be delivered.
Sand and cement screeds can be laid to falls (e.g. for drainage in wet rooms).
After laying the screed needs to cure. Curing is normally performed by covering the screed with plastic sheeting and leaving it for 7 days. It is preferable that the screed is not walked on during the curing. After curing the screed needs to dry out naturally before a covering is applied. As a rule of thumb, the screed is allowed to dry out for 1 day per mm of thickness.
New
floors - Screeding
Many new floors are constructed using concrete beams used to span the
foundations and then in-filled with concrete blocks. This is known as
block and beam construction. The finish on this type of construction is
not directly suitable for floor coverings and has to brought to a
suitable finish by applying a floor screed. If required, insulation can
be laid under and around the area to be screeded (floating screed) to
enhance thermal and acoustic properties.
Existing floors - Screeding
Existing concrete floors may be cold, out of level, damaged, and
unsuitable for a change of floor covering such as carpet, ceramic floor
tiles and vinyl floor coverings.
Floors that feel cold may not have been constructed to the insulation
standards now expected from modern floors. The insulation properties of
these floors can be increased by incorporating a layer of insulation
between the old surface and a newly applied floating screed.
Out of level masonry floors can be levelled up using sand and cement
floor screeds.
In the case of damaged masonry floors, it maybe possible to repair or
replace a small area of the floor to bring it up to the required
standard.
Self leveling latex is a pre-bagged cement based compound. They are applied in liquid form and flow to a smooth level surface for floor coverings. They are rapid hardening and in some cases can be walked on within 2 hours and covered in 24 hours. Normally laid in a thin layer (e.g. 1.5mm).
