Our System

Stronger. Smarter. Greener.

Our system

How our EPS cement panel system comes together

Speed, precision, and performance — engineered in. We combine a steel primary structure with high-performance EPS cement panels to create envelopes that are stronger, faster to build, and measurably more efficient than traditional methods.

KARRU Built system overview
Build sequence

From bare frame to finished wall — step by step

Steel structure
Step 1
Primary structure

Engineered steel handles vertical and lateral loads with predictable performance and clean tolerances.

Panel composition
Step 2
Panel composition

EPS core with cementitious skins and reinforcing mesh provides insulation, fire performance, and impact resistance.

Fixing & alignment
Step 3
Fix & align

Panels are fixed to steel, plumbed and leveled. Precision here ensures airtightness and a clean finish.

Joint reinforcement
Step 4
Reinforce joints

Adhesive mortar bonds panels; mesh/rebar added where needed for shear and seismic performance.

Service channels
Step 5
Services in-wall

Clean chases for electrical and plumbing routed within the panel without compromising integrity.

Finished wall
Step 6
Finish & seal

Render, cladding, or paint—multiple finish options with durable, low-maintenance performance.

System anatomy and testing
Performance

Measured where it matters

🔥 Fire

High performance ratings with documentation for submissions and certifiers.

🌡️ Thermal

Efficient envelopes; typical designs achieve up to ~R-3.6.

🔊 Acoustic

Quiet interiors for schools, homes, and healthcare facilities.

🧱 Seismic

Lightweight assembly reduces inertial loads; reinforced joints for shear.

FAQ

Common questions about the system

Are your homes compliant with Australian building codes?

Yes. Designs are aligned to the NCC and engineered to meet or exceed relevant local standards and overlays.

How long does it take to build?

Typical projects run 40–60% faster than traditional methods. A standard single-storey home can complete in under ~30 days on site (design dependent).

Are EPS panels waterproof and fire rated?

Panels are moisture-resistant and carry strong fire performance ratings. Documentation is included in submission packs.

Can I customise designs?

Absolutely. Plans are tailored to site, climate, and budget — with multiple finish systems available.

What’s included in a turnkey package?

Design, engineering, EPS panel supply, steel, roofing, rough-ins, finishes, and handover. We’ll scope inclusions clearly at proposal stage.
