Why do screeding experience gaps put a Burao floor at risk?

Floor screeding experience gaps in Burao show up as uneven finished levels and hollow patches that later floor finishes cannot hide. The screed sets the plane for tiles, thin coverings and door thresholds, so a crew learning on your floor passes its mistakes to every trade that follows. Check the crew before the first barrow is mixed.

Why does screeding experience matter more than other finishing work?

Screed looks like simple flat work, and it is not. A crew has to judge sand grading, cement content, water, compaction and setting time while walking backwards on fresh material, and each decision shows in the level. Too wet and the screed shrinks and curls at the edges. Too dry and it drags, leaving ridges under the straightedge. Thick patches and thin feather edges cure at different rates and can debond from the slab. None of this appears until the tiles go down and rock, or the door will not swing clear. The record that counts is floors that dried flat, not paper. Curing conditions on site change how fast a screed dries, so confirm them with the engineer or by monitoring the screed itself, and a crew that has only laid small domestic floors may never have met that condition. Ask the municipal engineer's office whether it holds any screeding specification or check sheet for local work.

How do you spot a screeding experience gap in Burao?

Ask how many floors the named crew has screeded and ask to see them, then check the results instead of the story. Take a 2 m straightedge and a spirit level to a recent floor laid by the same crew. Set the straightedge flat, look for the gap under it, and compare the reading between rooms and at a long run. Tap tiles or coverings for hollow sounds, which usually means the screed beneath is loose. Ask who laid it and who supervised it, since a labour gang that only mixed for another contractor has no screeding experience of its own. General practice is that a screed must finish flat enough for the covering chosen, so confirm the tolerance against the project's specification or engineer. Walk the site yourself in daylight; uneven levels are easier to see along a wall base than in the middle of a room.

What should a supervisor check during screeding?

Fix the method before work starts, not after. Confirm with the engineer that the mix and thickness suit the slab and the expected load, and have the quantities written down. Check the surface preparation: clean the slab, remove loose material, and agree how the screed bonds. Look at the sand and cement as they arrive and keep the water addition under one person's control rather than letting the gang top up the barrow. Check that the crew sets level screed rails, uses a straightedge across them, and works to them as it progresses. General practice is to cure the screed rather than let it dry fast, so agree how the surface gets covered and for how long. Before acceptance, record level readings room by room. If the result fails, check what your contract allows for rework before you agree anything about payment.

What to do next

Pick one room, agree a written level tolerance and a trial panel with the finishing supervisor, and inspect that panel with a straightedge and spirit level before the rest of the floor is screeded. Photograph the readings and keep them with the contract papers. If the panel fails, stop and ask the crew to show how it will correct the method.
