Subfloor preparation · Canterbury, CT1
Why concrete floors in Canterbury need checking for cracks, damp and laitance before flooring is fitted on top.
A slab that has never been screeded behaves differently to one that has, and both behave differently again if underfloor heating pipes run through it. Preparation work in Canterbury starts by establishing exactly what kind of concrete or screed base is present before deciding on the right treatment.
Preparation quotes for units near Blean usually separate levelling and damp-proofing as distinct stages, since combining them without proper drying time risks trapping moisture under the new floor.
Councils across Kent have differing records for when damp-proofing became standard, so age of build in Canterbury is only ever a starting clue, not a guarantee.
New-build plots around Canterbury can still be releasing construction moisture. Testing before fitting protects the floor and the customer, wherever in CT1 the plot sits.
Two floors of the same product, fitted in the same {town} street, can perform very differently depending on how well the subfloor beneath them was prepared. A flat, sound, correctly primed base is what allows adhesive to grip properly and lets resilient floorcoverings sit without telegraphing every imperfection underneath.
Laminate and engineered wood are generally more sensitive to residual moisture than LVT or vinyl, so concrete subfloors in {town} being prepared for these products are checked against the specific manufacturer's moisture threshold, which can be stricter than the figure used for resilient flooring.
Locate any underfloor heating pipes so grinding and testing avoid causing damage.
Run underfloor heating through its commissioning cycle before levelling compound is applied.
Verify flatness with a straight edge once mechanical preparation and levelling are complete.

Dust extraction equipment is used throughout mechanical preparation to control airborne dust and leave a clean surface ready for priming, minimising disruption on site.
No, each room is assessed on its own condition. A kitchen slab with old tile adhesive may need different treatment to a hallway with only minor dust and laitance.
The primer is matched to the levelling compound manufacturer's system and to the condition of the substrate, since using an incompatible combination can affect how well the latex bonds.
Yes, fibre-reinforced latex is generally used where dips, old tile lines or more significant unevenness need filling, giving added strength over a standard levelling compound.
A proper Canterbury survey establishes what a concrete floor actually needs, rather than applying the same preparation to every job regardless of condition.
We can assess and prepare a contaminated or uneven concrete floor before your new flooring goes down.
