Floor assessment, flattening & levelling

We check the floor with a laser level and a straight edge, then flatten it, level it, or both.

Includes

  • Laser level and straight edge check
  • High spots, low spots, breaks, slopes, unevenness and height differences found
  • Flattening, levelling, or both
A straight edge on a bare slab seen from floor level, with fine cracks running through the concrete.

Every floor is different, so we check it before we decide what to do. We use a laser level and a straight edge to find high spots, low spots, breaks, slopes, unevenness and differences in height.

Depending on what we find, the floor may need flattening, levelling, or both. Flattening takes out the ups and downs across the surface. Levelling brings the whole floor to one even plane.

What we look for

  • A straight edge across a hallway slab rocks on a raised crest, with gaps under both ends.

    High spots

    Raised areas, trowel ridges and hard lumps sitting above the rest of the floor.

  • A straight edge on a slab with daylight showing under its middle, where the floor dips.

    Low spots

    Dips that sit below the rest of the floor.

  • A hairline crack running across a bare slab, and a patch of broken surface beside it.

    Breaks and cracks

    Broken edges and cracks in the existing surface.

  • A laser line runs level along the wall while the floor below falls away from it towards the far end.

    Slopes and falls

    A floor that runs downhill across a room.

  • A straight edge across a slab touches in a few places, with light showing through the gaps beneath it.

    Unevenness

    A wavy floor with no single high or low point.

  • A spirit level held level across a doorway, with a small rule under its far end measuring the drop to the floor in the next room.

    Differences in height

    A step or change in level between rooms or at a doorway.

Flattening or levelling

They're different jobs, and a floor can need one, the other, or both.

  • A straight edge across a slab with a crack running through it, beside cupboard doors leaning on the wall.

    Flattening

    Takes out the ups and downs across the surface, so a straight edge sits flat.

  • Fresh levelling compound poured across a kitchen and living area.

    Levelling

    Brings the floor to one even plane across the room.

Where our work sits

  1. New floorLaid by your installer, or by us if it's floorboards.
  2. Correction layer Our workFills and corrects the low areas, where needed.
  3. Prepared surface Our workThe surface prepared for the new floor.
  4. Existing slabThe concrete that's there now.
Floor layers from the top: the new floor, the correction layer, the prepared surface, and the existing slab or subfloor. The correction layer and prepared surface are Rhino's work.

From our jobs

Questions

Do I need to know what the floor needs before I get in touch?

No. Tell us what's down now and what's going on top. Working out what the floor needs is our job.

What's the difference between flattening and levelling?

Flattening takes out the high and low spots across the surface. Levelling brings the floor to one even plane. A floor can need one or both.

What do you use to check the floor?

A laser level and a straight edge, and we take our time. Checking a floor by eye, or with a short straight edge, isn't good enough.

Do a few millimetres really matter?

Yes. A floor that's flat and level to the millimetre lets the new floor go down properly and stay free of problems later. It's easy to underestimate.
