Technical advantages

COST EFFECTIVE
The voids created with SKYDOME forms allow considerable savings in concrete compared to traditional full-concrete slabs. SKYDOME can be easily installed on H20 timber beams, thus saving any other scaffold system.
SAFETY
SKYDOME is completely independent, thus it does not require any support or safety structures. The system can be installed from below and it guarantees maximum safety to the workers.
TECHNOLOGY
The dome-shaped forms of SKYDOME allow to create large-spanning bi-directional waffle slabs guaranteeing maximum structural efficiency thanks to the lower self-weight of the structure.
DISMANTLING
Concrete does not stick to plastic, thus dismantling is extremely fast and easy without need of releasing agents. All elements can be cleaned just with water.

REUSE
Thanks to its shape and the material features, SKYDOME can be reused for more than 100 times.
HANDLING
The material is very light and can be dismantled and moved quickly on-site without using cranes. SKYDOME can be stored in tight spaces, even in damp ones.
RESULTS
A slab made with SKYDOME can be left exposed or covered with a plasterboard ceiling.
ECOLOGIC
SKYDOME system is completely made with recycled plastic materials.

Technical chart and Package

Installation

SKYDOME allows the reduction of the slab’s self-weight without using any disposable material, thus all components of the system can be reused and it allows an advanced dismantling.

Concrete does not stick to plastic, making dismantling quick and easy.

No releasing agents are required: all the elements of the system are easily cleaned just with water.

Installation Guide

Place the steel props and insert the timber beams. Attach the item to the support wall.

Place the first row of cubes and beams.

Place the side panel of 25mm thickness.

Place the second row of elements at the same time of the transversal beams.

Place the first SKYDOME dome.

Repeat steps 4 and 5.

Place the first balance panel of 25 mm thickness.

INSTALLATION INSTRUCTIONS
In order to place correctly the balance panels on the side ribs, it is essential to consult GEOPLAST project tables before proceeding with the installation of the elements of the slab.

Dismantling SKYDOME system

Remove props and timber beams in pairs.

Remove the cubes.

Remove all the beams.

Remove SKYDOME domes with a bent iron bar that will be inserted into the holes on the side of the dome.

In correspondence of the ribs, shore up the slab as shown in GEOPLAST project tables until the concrete has cured.
