Why Catford and Convoys Wharf homes take pumped screed
Pumped screed earns its keep on big, open floors that can be filled in a single pour. That describes the new homes going up in Lewisham. Around Catford, Lewisham Gateway and Convoys Wharf in Deptford, new flats and townhouses are being built with underfloor heating and acoustic insulation between units, and a pumped screed suits that build-up well.
The share of new stock is not small: 18% of the borough's homes date from 2000 or later. Buildings of that age are generally designed with enough depth for insulation and a flowing screed, and the screed fills every gap around the heating pipes without leaving voids.
Thinner sections are part of the appeal. Floating over insulation in a home, a flowing screed can go down at about 35mm, where sand and cement would want around 65mm. Getting to SR1 or SR2 is straightforward with a flowing mix, and because it barely shrinks, the floor needs far fewer joints, leaving a sound base for tiles, LVT or engineered boards.
Older homes can benefit too. A rear extension on a Victorian terrace often ends in one wide kitchen and living space, and a pumped floor covers it quickly. You can have a liquid screed with either a calcium sulphate or a cement binder. For the first, anhydrite grades and testing has the detail, and if you are still deciding on a method, read which suits you, liquid or traditional.
Pump access from Lewisham terraces to upper flats
The pump and mixer never come indoors; screed travels to the room through a hose, along the hallway or up through the building. On a townhouse plot with a driveway that is simple. Between Brockley and Hither Green, where Victorian terraces line the streets, the mixer may have to sit in the road, so mention parking restrictions, bus routes or tight access when you ask us to price it.
Flats are a good match for a hose. With 56% of Lewisham's homes being flats, many floors sit well above the street, and carrying sand and cement up the stairs would be slow and heavy work. A hose climbs a stairwell with far less disruption, provided the route is agreed with the building manager and protected.
Inside, check the preparation before the day. Edge strip must run round every wall, the membrane over the insulation must be taped at the joins, and doorways need damming. Keep windows closed and the room draught free for the first two days. You can walk on it after 24 to 48 hours. Flooring is a different matter: it waits until the screed is dry, and you should budget roughly one day per millimetre of depth up to 40mm.
