Floor screeds for live hospitals.

Flowing and liquid screeds installed inside operational hospitals and healthcare estates, phased carefully around clinical activity and ward access.

The work

Floors laid while the building keeps caring

Healthcare floors have to go in without disrupting clinical work, meet hygiene and performance requirements, and be ready on time. Three constraints, and on most projects the first one governs the other two.

We use low-disruption methods like pumped flowing screed and phase the works around wards, theatres and access routes. We have delivered flowing screed in an operational hospital, and at the John Radcliffe.

Proof, not promises. On a live hospital, the method statement is the product as much as the floor is.

On site

Built around your operation, not against it.

We plan the method, phasing and plant so work continues around us and the floor goes down right first time.

The sector

What makes a hospital floor different

A hospital is not a construction site that happens to have patients in it. It is a working clinical environment that has temporarily let you in, and the difference shows up in five places.

  • The programme belongs to the trust, not to you. Theatre lists, ward moves, decant schedules and infection control all outrank the flooring programme. Work happens in the window you are given, and the window moves.
  • Infection control is a hard constraint. Dust containment, hoarding, air pressure regimes, agreed routes and clean-down are conditions of access rather than good practice.
  • Noise and hours are restricted. Wards adjacent to the work put real limits on when you can run plant. A method that needs a finishing crew back at nine in the evening may simply not be allowed.
  • Access is genuinely difficult. Lifts sized for beds and not for plant, corridors that cannot be blocked, doors that must stay clear, and delivery routes shared with clinical logistics.
  • The finish matters clinically. Welded vinyl, coving and hygienic finishes need a base at the right tolerance and the right moisture content, and getting either wrong pushes the whole fit-out.

The method

Why pumped screed suits healthcare

Speed and containment are the reasons this method dominates healthcare work. A pumped flowing or self-compacting screed arrives through a hose. There is no barrow run down a clinical corridor, no floor full of labourers, and no material stacked in a space that a hospital needs. A large area goes down in a single visit and the crew leaves.

Self-compacting systems go further and remove the power floating step, which is normally what forces evening working on a screeded floor. On a ward that is a decisive advantage rather than a convenience. See self-compacting screed and flowing screed.

The trade-off is drying. Moisture-sensitive floor coverings, which is most of what goes down in a hospital, need the screed to reach a specified moisture content before they can be laid. That is a programme item to be designed in, and it is the single most common cause of a healthcare floor handing over late.

Scoping

The decision you are actually making

What are the real access windows?

Not the ones in the tender programme. The ones the trust will actually give you, including how often they move.

Which screed system does the site permit?

If late working is out, self-compacting is the answer. If it is allowed, flowing screed may be cheaper.

What is the floor covering, and when does it need the base?

The covering manufacturer's moisture requirement sets the drying period, and the drying period sets everything else.

Is it a screed or a slab?

New-build healthcare includes structural slabs and plant areas as well as screeded decks. Both are priced differently.

What are the hygiene and performance requirements?

Coving details, falls to drainage in wet areas, and the substrate specification for welded finishes.

How is the work separated from the clinical estate?

Hoarding, routes, deliveries, waste and wash-out all need agreeing before mobilisation.

Capability

Plant and crews, self-delivered

Our own operatives, our own pumps, our own placing booms, start to finish. Nothing subcontracted.

That matters on a hospital because everyone who walks onto that site has to be inducted, vetted where required, and briefed on the infection control regime. A subcontracted gang who change week to week is a problem for the trust and a risk for you. Ours do not.

Our track-mounted placing booms, rare kit in this country, reach upper decks and restricted spaces without craning plant up. On a constrained hospital site, where there is often nowhere to put a crane and no appetite for a lift over an occupied building, that is frequently what makes the job possible at all.

Delivery

Constraints handled

Occupied and operational buildings are the norm on this sector. Work is phased around wards, theatres and clinical activity, in the windows the trust gives us.

  • Infection control regimes. Dust containment, agreed routes, hoarding and clean-down built into the method statement rather than added afterwards.
  • Restricted hours. Self-compacting systems remove the late working that would otherwise be required.
  • Difficult access. Placing booms and line pumps where lifts, corridors and doorways rule out conventional plant. See concrete pumping.
  • Decant and phased handover. Areas released, worked and handed back in sequence, with honest durations for each.
  • Moving programmes. Clinical priorities change. We plan for the window shifting rather than pricing as though it will not.

Proof

Evidence and documentation

  • Surface regularity survey against the specified BS 8204 class
  • Moisture readings before floor coverings where we are asked to take them
  • Delivery tickets and batch records
  • Pour records: area, depth, date and conditions
  • Manufacturer's declaration of performance for the system installed
  • RAMS issued and agreed before mobilisation, written to the site's infection control and access regime
  • Sign-off pack at handover

FAQs

Common questions

Can you lay floors in an operational hospital?
Yes. We use low-disruption methods like pumped flowing screed and phase works around clinical activity. We have delivered flowing screed in an operational hospital.
How do you control disruption on a healthcare site?
Through method, phasing and clean, fast systems, planned around wards, theatres and access routes. Dust containment, agreed routes and clean-down are written into the method statement rather than added on site.
Can you avoid evening and night working?
Usually. Self-compacting screed removes the power floating step that normally forces late shifts, which is why it is specified so often on live healthcare work.
Do you meet healthcare hygiene and performance requirements?
Yes. The floor system is selected to meet the specified performance and finish, including substrates for welded vinyl and hygienic coverings, and falls to drainage where required.
How long before floor coverings can be laid?
It depends on the system, the depth and the drying conditions, and on the moisture content the covering manufacturer requires. It is the item most likely to affect a healthcare handover date, so it should be planned rather than assumed.
How do you handle difficult access?
With our own line pumps and track-mounted placing booms. Hospital lifts and corridors rarely take flooring plant, and pumping removes the need for them to. Upper floors are reached without craning plant up or over an occupied building.
