BubbleDeck precast concrete slabs are suitable for use in all building types especially open floor designs such as commercial, educational and institutional buildings.
Although the technology can be adjusted to suit almost any floor slab arrangement our experience - gained over more than 400 buildings completed around the world in the past decade - has shown that most building uses fall into the slab categories shown in the table.
Experience has also shown the most cost effective application of the floor technology is through semi-precast elements.
The size of the elements should be maximised to increase cost efficiency, however this is generally limited by local transport restriction.
Typical dimensions are:
|Width||2.4m to 3.0m|
|Length||9m to 10m|
The slab types given in the table can be applied over the following range of spans and strength.
Note the final design will dictate the ultimate choice of slab.
Simple site installation
|Prop||1. Temporary supports||Typically 2m spacing|
|Place||2. Place elements||Semi-precast panels lifted into position|
|3. Joint reinforcement||Loose straight splice bars and shear reinforcement across columns if needed|
|Pour||4. Preparation||Seal joints, clean and moisten precast concrete layer|
|5. Concreting||Pour, vibrate and float|
|6. Temporary works||Remove, typically after 1-2 weeks, according to specific site advice|
