About our temporary works & propping service in Neath Port Talbot

Temporary works and propping are the short-term supports that carry floors, walls and roof loads while a structural wall is taken out or a beam is put in. Adjustable steel props, timber spreaders and steel needles pass the weight safely down to the ground until the permanent steel is installed, packed tight and able to take the load itself.

Temporary works & propping are one of the most common structural jobs in homes across Neath Port Talbot. That includes Neath and Briton Ferry, plus smaller towns and villages nearby. Every job starts with a survey visit, then calculations from a structural engineer, so the steel suits the house in front of us rather than a rule of thumb.

What to expect

  • Props take up floor space for the length of the job, usually in the rooms on both sides of the wall. Furniture needs moving back, and nobody else in the house should knock, adjust or hang anything from the props.
  • Every prop delivers a concentrated load that has to go somewhere. Before any are set up, the floor beneath is checked, because a suspended timber floor or a thin slab may not take that load without extra support carried down to the ground.
  • On larger jobs, a temporary works register or permit records when the props were installed, inspected, loaded and removed. It creates a clear trail showing each stage was checked before the next one began.
  • For simple openings, the engineer's calculations usually show the propping arrangement. Larger or unusual jobs, such as removing several walls or working beneath chimney stacks, may need a separate temporary works design prepared by an engineer.
  • In older homes with lime mortar and soft bricks, the masonry above an opening can loosen once it is cut. The engineer may call for closer needle spacing or fuller support, because old walls can arch or drop in ways a modern wall does not.

Four stages, one team

  1. Survey in Neath Port Talbot

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. Building control

    We submit the application or notice to Neath Port Talbot County Borough Council under the Building Regulations as they apply in Wales, before work starts.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building rules for Neath Port Talbot

Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Neath Port Talbot the application goes to Neath Port Talbot County Borough Council or a registered building control approver, with the engineer's calculations, and a completion certificate follows the final inspection.

The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Temporary works & propping in Neath Port Talbot: your questions

Can you work on older or listed homes in Neath Port Talbot?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

What happens at the survey visit in Neath Port Talbot?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

Why do you need props to remove a wall?

Because the wall is holding up weight that still has to be supported while it is gone. Props and needles carry the floors, walls or roof above down to the ground until the new steel beam is fitted, packed and taking the load. Without them, the structure above could drop, crack or, at worst, collapse.

How long do props have to stay in after a beam is fitted?

Until the permanent steel is packed tight and able to carry the load. That includes time for the padstone and packing mortar to gain enough strength, which depends on the mix and the weather. On a typical opening, props are in for a few days before being released gradually.

How many props do I need to take out a load-bearing wall?

It depends on the span, the weight above and the strength of the floor the props stand on. The engineer's calculations or a temporary works design set the number and spacing. It is not something to guess, because too few props, or props in the wrong place, can let the structure move.

What is needling a wall?

Needling means cutting holes through a wall just above where an opening will go and passing short steel beams, called needles, through them. Each needle is supported on props on both sides, so the masonry above rests on the needles while the wall below is removed and the permanent beam is fitted.
