Pipe cover and depth in Isle of Dogs apartments
Tower fit outs on the Isle of Dogs, at Blackwall and in Limehouse need pumped liquid screeds, acoustic insulation and underfloor heating, often at height. The build-up is the same from floor to floor: slab, acoustic insulation, heating pipes, then screed. Getting the depth right over the pipes is what makes the system warm evenly and keeps the floor strong.
On a tower floor, liquid screed needs 25mm minimum above the pipework, so the layer finishes near 45 to 50mm in depth, and sand and cement would call for roughly 45mm of cover. In an apartment the whole build-up has to match door thresholds, lift lobbies and the levels set by the architect, so the thinner liquid screed for Tower Hamlets flats is the usual choice.
No air can be left trapped around the pipes. Liquid screed flows around them as it is poured. An edge strip around every wall lets the screed expand as it heats, and the insulation below stops heat escaping into the flat underneath. Insulation, membrane and perimeter strip are all checked before the pour, and gaps can be filled by our insulation and membrane team.
Once the screed is finished and dry, its surface is level enough to take LVT, engineered wood or tiles laid directly on top of it in the flat. Fitting the heating pipes is not part of K & B's work; covering them is.
Switching the heating on in Blackwall and Limehouse flats
Bring a new heated floor up to temperature gently. A calcium sulphate pour can normally have its heat turned on roughly 7 days after it is laid, but sand and cement stays cold for 21 days as the shortest wait. The heating is then commissioned gradually: a low flow temperature at first, raised in small steps with pauses, until it reaches working temperature. Turning it up full on day one is how a new floor cracks.
We leave written heat-up guidance, so the heating engineer, the flooring fitter and whoever owns the flat are working to the same timetable. The heat helps the screed dry, but flooring still waits for a moisture test. For the full timings, read our explainer on drying times.
Refurbishments are the other case. The 1980s and 1990s Docklands homes around Millwall and Cubitt Town are due for refurbishment, and if a refit adds heating, the floor height available becomes the limit. Budget £20 to £35 per m² for liquid screed on heated floors, going by published trade prices. For heated floors across the river, see underfloor heating screed in Greenwich.
