About our temporary works & propping service in Blaenau Gwent

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.

If you are planning temporary works & propping in Blaenau Gwent, the order of work matters as much as the steel: survey, calculations, approval, propping, installation, inspection and making good. That includes Ebbw Vale, plus smaller towns and villages nearby. We run that sequence for you as one job with one point of contact.

What to expect

  • Propping normally goes in on the first morning and stays until the beam is carrying. For a typical opening that is a few days, and longer where padstone mortar needs time to cure before the load is transferred onto it.
  • 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.
  • Adjustable steel props are the workhorse, with timber spreaders on top to share the load across several joists. Steel needles pass through the wall to carry masonry above an opening, and prop head attachments known as masonry support heads support brickwork without needles.
  • 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.
  • Needle holes leave neat square gaps in the wall above the new beam. Once the props are out, these are filled with brick or block and mortar, then plastered over with the rest of the making good.

From survey to sign-off in Blaenau Gwent

  1. Look and measure

    We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. Building control

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

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Blaenau Gwent

Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Blaenau Gwent the application goes to Blaenau Gwent 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 Blaenau Gwent: your questions

Do you cover Blaenau Gwent for temporary works & propping?

Who approves temporary works & propping in Blaenau Gwent?

Structural work in Blaenau Gwent needs a building control application to Blaenau Gwent County Borough Council under the Welsh regulations, with a commencement notice before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.

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.

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.

Can I stay in my house while it is propped?

Usually, yes. The props take up space in the rooms either side of the work, so those rooms will be out of use, but the rest of the house can be lived in as normal. The props must never be moved, knocked or adjusted by anyone other than the installation team.

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.
