Levelling knock throughs and extensions in Banbury homes
Knock throughs are a staple of the town's post-war and mid-century housing, and they leave a telltale problem. Where a wall comes out, the two rooms either side rarely finish at exactly the same level, and there is often a strip of rough floor where the wall stood. A rigid floor laid over that will rock or crack.
A poured compound takes that ridge and the step out. We normally lay it between about 2mm and around 10mm (a few products go deeper), and it runs out smooth on its own. Flatness is judged with a 2m straightedge: SR1 means a gap of 3mm at most, SR2 means 5mm, and thin sheet floors often ask for SR1.
The same approach joins a new extension to the old house. Once the extension screed is dry, compound can be feathered across the join so one floor runs through.
Before any compound goes down, the floor is primed. Bare concrete, an old cement screed and an anhydrite floor each need their own primer.
Compound is not always the answer. A floor that dips well beyond 10mm, or a screed that is crumbling, will tend to crack and debond under a deep pour. Then a new screed is the right fix, such as hand-laid sand and cement in Banbury, or a thin latex screed where only a few millimetres are needed.
Banbury shop and unit refits, Castle Quay to Thorpe Way
Commercial refits need flat floors on short programmes. In the centre, the Castle Quay Shopping Centre sits beside the Oxford Canal, and when a shop there is refitted, its floor has to be ready for new vinyl, LVT or tiles. Out of the centre, when a unit on the Wildmere or Thorpe Way industrial estates is refitted as an office or showroom, its floor needs the same preparation.
A typical refit starts with lifting old carpet tiles or vinyl and removing adhesive. High spots and contamination come off next, with concrete floor grinding where needed. The floor is primed for its base, then a fast drying compound is poured to SR1 or SR2 so the new finish can follow quickly.
Work can be phased so part of a unit is handed back while the next area is prepared. Tell us the finish, the opening date and any hours we must work around.
Factory floors on those estates are a different job. Where a floor carries forklifts, racking or production equipment, damaged areas need repairing and a heavy duty screed may be needed before any finish. Resin and polished concrete are outside what we do.
