Flat floors for New Addington semis and extensions
New Addington began in 1935 as a garden village on Fisher's Farm, and post war prefabs and semis were added later. Those semis need extension slabs and levelling, and the two jobs are linked. When a new extension floor meets the original house, the levels rarely match exactly, and a floor covering laid across both will show the join. A thin compound layer bridges it and gives one continuous surface, so LVT or large tiles run from the old kitchen into the new room without a visible step.
Under BS 8204, the test is a 2m straightedge and a feeler: SR1 means 3mm at most beneath it, SR2 5mm, SR3 10mm. Many thin sheet finishes need SR1, which an older floor seldom meets on its own.
A typical pour is somewhere between 2mm and 10mm deep, and a few products are made to go thicker. Before it, we clean the floor, scrape off anything loose and prime for the base underneath, whether that is concrete, sand and cement, calcium sulphate or the remains of old adhesive. Mismatch the primer and the compound can peel up later. Where the base itself needs work, floor preparation comes first.
Levelling compound will not rescue a floor that has given up. Poured too deep over a hollow or crumbling base, it can crack and debond. Floors like that need a new screed; see Croydon sand and cement screed.
Shop and unit refits on Purley Way
Purley Way is Croydon's main commercial corridor, with retail parks including Valley Park. In the town centre, the Whitgift Centre and Centrale anchor the shopping. When a unit in either place is refitted, the new floor finish may need a flatter base than the old one had.
A shop floor is usually levelled after the old finish comes up. Carpet tile adhesive, old vinyl and patch repairs all have to be dealt with before compound goes down, and concrete floor grinding removes coatings and high spots. Then the floor is primed and a fast drying compound is poured, so the fitters can follow quickly and the unit opens on time.
The Purley Way masterplan proposes more than 100,000 square metres of industrial floorspace alongside new homes, and new units will need level floors for their tenants' finishes too. For larger commercial screeds rather than a skim, see commercial screeding in the borough.
We do not sand wooden floors, lay resin or polish concrete. Our part is the flat, sound base those finishes need.
