Where is a 50mm void former typically used?
The 50mm depth is ideal for shallow voiding, slab rebates, trenching adjustments, drainage channels and low-profile separation cavities.

Does a 50mm void former help minimise concrete volume?
Yes, even at this thickness the void former reduces concrete usage and pour weight, creating efficiency gains on-site.

How is the 50mm void former installed?
Sheets are positioned within formwork or base layers before pouring. Once cured, the void former maintains consistent rebate or cavity spacing.

Can 50mm void formers be used outdoors or in damp environments?
Yes, Rebul bagged void formers perform reliably when installed correctly in exposed, humid or moisture-affected construction settings.

Is 50mm suited to commercial or residential projects?
Absolutely, this size is widely used across slabs, tilt panel works, trenching, precast fabrication and small-scale void creation.

How strong is a 50mm honeycomb void former?
The engineered honeycomb core provides excellent compressive strength relative to its depth, ensuring dependable support when embedded within concrete or formwork.

Is honeycomb cardboard strong enough for voiding applications?
Yes, its cellular structure distributes load effectively, making it a proven and trusted structural voiding material.

What sizes are available?
Rebul manufactures 50mm, 75mm and 100mm honeycomb void formers for a range of engineered applications.

Are these void formers recyclable?
Yes, honeycomb void formers are recyclable and offer a sustainable alternative to polystyrene or timber systems.

Can 50mm void formers be used in tilt panel or precast projects?
Definitely, this size is commonly used for rebate formation, separation cavities and spacing layers in precast construction.
