Pumping distance and hose runs on Exwick's terraced streets

Exwick's terraces were built well before wide driveways or off-street parking became standard, so it is common for both sides of the street to be lined with parked vehicles and for the front door to open directly onto a narrow pavement. In that layout there is no realistic way to bring the wagon close to the threshold, and the practical solution is to stand it at the nearest available legal space and run a hose the remaining distance.

That distance can be considerably longer than on a detached property with its own driveway, sometimes running the length of several house frontages before reaching the correct address, which needs to be factored into both the equipment chosen and the time allowed for the pour.

Liquid screed is designed to flow well, but pumping it over a long distance still means overcoming friction along the length of the hose, and any tight bend concentrates that resistance further. Pushed too far or too fast for the equipment in use, this can begin to separate the mix or slow the flow unevenly, which shows up as inconsistency in the finished floor rather than as an obvious problem on the pump itself.

The way this is managed in practice is by matching pump capacity and hose diameter to the measured distance and number of bends before the job starts, and by keeping the discharge rate at a steady pace suited to that run rather than trying to rush a long pump simply because the wagon is standing some way off.

Between the wagon and the floor, a long hose run on a terraced street often passes along a pavement, through a front door, and sometimes down a narrow hallway before reaching the room being screeded. Each of those sections needs protection from the weight and movement of the hose, and each needs to be wide enough and clear enough of obstructions that the hose can be repositioned as the pour moves across the floor.

Checking this route in advance, rather than assuming the hose will simply fit, avoids finding out mid-pour that a doorway is too narrow or a hallway turn too tight, either of which can slow the job down at the point where consistency and timing matter most.
