Falsework for Slab — Dubai & UAE
Falsework for slab is the temporary structural support system erected beneath a concrete floor slab during pouring and curing. It carries the weight of formwork, wet concrete, and construction loads until the slab gains enough strength to be self-supporting. In UAE construction, the three main falsework systems are cuplock scaffolding towers, acrow props, and drop-head prop systems.
Falsework Systems We Rent
Britania stocks three slab falsework systems. The right choice depends on slab thickness, load requirements, and how quickly you need to cycle between floors.
Cuplock Falsework
Heavy-duty scaffolding towers for thick slabs, transfer beams, and podium decks. Load capacity up to 2,500 kg per leg.
Monthly RentalAcrow Props & Slab Formwork
Individual adjustable steel props for standard residential and commercial slabs. Simple to set up, cost-effective for smaller areas.
Monthly RentalDrop-Head Prop Systems
Early-striking props for fast floor cycling. Strip formwork at 3 days while props remain for re-shoring. Ideal for multi-story projects.
Monthly RentalCuplock Falsework vs Acrow Props vs Drop-Head Props
All three systems support concrete slabs during curing. The right choice depends on slab thickness, project size, and floor cycle requirements.
| Feature | Cuplock Falsework | Acrow Props | Drop-Head Props |
|---|---|---|---|
| Best for | Heavy slabs, transfer beams, podium decks | Standard residential slabs (150-200mm) | Fast floor cycling, multi-story projects |
| Load capacity | Very high (2,500 kg/leg) | Standard (rated per prop) | Standard (rated per prop) |
| Setup complexity | Moderate (grid assembly) | Simple (individual placement) | Simple (individual placement) |
| Early striking | Not standard | No — full removal required | Yes — strip formwork at 3 days |
| Floor cycle speed | 7-14 days typical | 7-14 days typical | 3-5 days (formwork reuse) |
| Cost per sqm | Higher (heavy-duty system) | Lowest | Mid-range (saves time) |
| Rental model | Monthly | Monthly | Monthly |
When You Need Slab Falsework
Residential Slab Pours
Propping and formwork for villa and low-rise residential floor slabs. Acrow props and plywood panels for standard 150-200mm thick slabs with quick strip and cycle times.
Commercial Floor Plates
Large-area slab formwork for office buildings, malls, and hotels. Drop-head prop systems allow early striking at 3 days, keeping your floor cycle on schedule.
Heavy Transfer Slabs & Podiums
Thick podium slabs, transfer beams, and post-tensioned floor plates require cuplock falsework towers. Higher load capacity and closer spacing than standard propping.
Multi-Story Floor Cycling
Projects with repetitive floor pours benefit from drop-head props or cuplock falsework that can be systematically stripped and re-erected floor by floor with minimal material on site.
Propping Density & Indicative Pricing
Typical propping density for standard concrete slabs is 1 prop per 1.5-2.0 sqm. Thicker slabs and transfer beams require closer spacing — sometimes 1 prop per sqm or less. Prop-based slab support for a typical floor plate starts from AED 3,000-8,000 per month depending on area and slab thickness. Cuplock falsework for heavy loads is quoted separately based on tower height, grid spacing, and project duration. Send us your slab drawings for an exact quantity calculation and price.

Frequently Asked Questions
What is falsework for slab?
Falsework for slab is a temporary structural support system erected beneath a concrete floor slab to carry the weight of formwork, wet concrete, reinforcement, and construction loads until the slab cures and becomes self-supporting. In UAE construction, the most common falsework systems are cuplock scaffolding towers, acrow props, and drop-head prop systems.
How many props do I need per square metre of slab?
Typical propping density is 1 prop per 1.5-2.0 sqm for standard slabs (150-200mm thick). Thicker slabs, transfer beams, and podium decks require closer spacing — sometimes 1 prop per sqm or less. Share your slab drawings with us and we will calculate the exact quantity.
When should I use cuplock falsework instead of props?
Cuplock falsework is the better choice when slab thickness exceeds 250mm, when you are pouring transfer beams or podium decks, or when the project involves multi-story floor cycling. Cuplock towers distribute load across a grid of standards and ledgers, providing significantly higher capacity than individual props.
What are drop-head props and when should I use them?
Drop-head props have a mechanism at the top that lets you lower the formwork panels while the prop shaft stays in place for re-shoring. This means you can strip and reuse the plywood and beams on the next floor in as little as 3 days after the pour, without removing all the props. They are ideal for projects with repetitive floor cycles where speed matters.
How long does concrete need to cure before I can remove the falsework?
Standard practice in the UAE is 7 days for normal slabs and 14-21 days for thick transfer slabs, but always follow the structural engineer's specification. With drop-head systems, you can strip formwork earlier while leaving the props in place for continued support. Cube test results confirm when the concrete has reached the required strength.
Do you supply the plywood and beams as well?
Yes. We supply complete slab formwork systems including marine plywood panels, primary beams (H20 timber or aluminium), secondary beams, props or cuplock falsework, and all accessories. One supplier, one delivery.
