On our sitesPreparing the subfloor: installation starts before the covering
Flatness, moisture, cleanliness: three checks that decide how a resilient or laminate floor will hold. What our installers verify before opening the first box.
Flatness
A resilient floor reveals every defect in the subfloor: a 2 mm bump shows in raking light. We apply a levelling compound as soon as the 2 m straightedge shows more than 5 mm deviation; for glued LVT we aim for 2 mm.
Moisture
A new screed dries roughly one week per centimetre of thickness. Installing too early ruins the adhesive or swells a laminate. On a ground floor without a barrier, a vapour barrier film under the underlay is mandatory.
Renovation over an existing floor
Laminate and click LVT go over sound tiling, with wide joints filled. An old glued PVC that holds can take a suitable levelling compound; if it is lifting, it must be removed. Loose-lay tiles (Saga²) go down without glue on clean, dry subfloors, ideal for a shop that cannot close for long.
