The Citra Building Technology

An Innovative, Sustainable Construction Solution

Citra offers a faster, more cost-effective, and environmentally sound approach to building. Here’s a deeper dive into how it works:

The EPS Foundation

We use Expanded Polystyrene (EPS), a globally trusted insulation material, as the core of our system.
EPS is lightweight, shape-flexible, and provides excellent thermal performance (with R-values customisable to your climate zone).
We tailor EPS thickness, and density (ranging from 15kg/m3 to 30kg/m3), or substitute Graphite Polystyrene (GPS, such as BASF Neopor) to match your exact structural and insulation needs.

Magnesium Oxide (MgO) Reinforcement

Chloride-free MgO strips (with high flexural strength) embedded within the EPS provide:

Strong structural support for walls and roofs, designed to withstand seismic activity and high-wind zones.
A secure base for our specialized plaster, eliminating the need for steel or glass fiber mesh.
This creates a durable composite structure that boasts fire resistance exceeding 1 hour rate.

High-Performance Plaster

We apply a specialized cementitious plaster mix, fortified with high-strength chopped fibers, directly to the EPS-MgO framework.
Plaster thickness is customized (typically ranging from 15mm to 30mm) based on the size and load requirements of your building.
Our plaster formulation offers optimized compressive and flexural strength.

Optional Basalt Rebars

For extra strength in roofs and slabs, we use basalt rebars under the MgO strips.
Basalt offers superior tensile strength to steel (up to twice as strong), is more sustainable to produce, and chemically inert, offering exceptional longevity.
This allows for thinner plaster coatings in ceilings as corrosion protection isn’t required.

Waterproofing and Reflectivity

A waterproof, reflective layer on the roof keeps the system cool and weatherproof, ensuring long-term performance.
We use materials with high Solar Reflectance Index (SRI) to minimize heat gain.

Proven and Expanding

Coming Q2 2024: Support for three-story structures without steel, with engineering specifications available upon request.
The Citra Building Technology has been used successfully in single and two-story homes with conventional slabs.

Citra's simplified construction process means faster project completion, saving time and money for developers, owners, and builders.

Reduced material needs, streamlined construction, and lower energy costs make Citra a competitive choice for a range of budgets.
