POROTHERM is an aerated, honeycomb-matrix, clay block (not facing brick) walling system. Simple and fast construction requires only clay block, concrete and steel, with a finished render. It’s not a cladding system, but a structural walling system.


Developed by Wienerberger, Europe’s largest manufacturer of clay construction materials, it is now used in up to 80% of commercial and residential construction in Europe. Used for hundreds of years globally for its amazing performance and durability, its use is fast gaining popularity worldwide.

With up to 25 POROTHERM projects here in New Zealand at various stages of planning and completion, POROTHERM is gaining recognition in the NZ building market.


Cost per m2 is comparative to a 140mm timber frame build. Seismic AND fire-resistant, durable, breathable, and 100% natural. The block has a design life of 150 years and material life of 400+ years. Average block thickness of 250mm, R-values between 1.7 – 5.4. Thermal mass in POROTHERM walls provide warmth in winter and cooling in summer to create an all-year-round living temperature between 18-22C. Near zero energy and maintenance requirement.

Porotherm Performance.

FIRE RESISTANCE

Porotherm blocks are non-combustible and achieve an A1 resistance rating

THERMAL EFFICIENCY

Average block thickness of 250mm, R-values between 1.7 – 5.4. Thermal mass in POROTHERM walls provide warmth in winter and cooling in summer to create an all-year-round living temperature between 18-22C.

MOISTURE MANAGEMENT

No condensation, humidity, mould or dampness – completely dry.

VERY HIGH SEISMIC PERFORMANCE

Design-engineered to meet the world’s highest seismicity requirements.

COST-EFFECTIVE BUILD PRICE

Finished wall price per m2 competes with high-end timber-frame construction.

BLOCKBUILD

Building with clay block is nothing new. This construction system has been around in Europe for over 150 years and forms up to 85% of building in some countries throughout Europe. So it makes sense that as many New Zealanders travelling to Europe and experiencing the sense of longevity living in these buildings provides – why not re-create this in NZ?  

Feeling the difference between a timber/stick frame home and a clay/block build home – there’s just no comparison.

Once you step inside these walls; it’s quiet, solid and safe. These are true forever homes because they will still be standing in 400+ years, unchanged.

Kiwis are becoming much more discerning and yearning for a better way to build. With the realisation of the high durability & the high performance a Porotherm clay block home provides, for the same cost as a timber stick frame home - it’s no wonder Kiwis are turning to BLOCKBUILD.

  • No Curing

  • Fastest way of construction

  • Easy to transport – light in weight, compact, large coverage

  • Dry Wall System

  • Clean site

  • Zero Wastage
     

Most building sites are known to waste an average 23 litres of water per m2 during wall construction. DryFix addresses the problem of using water to mix concrete and clean up waste on site.

Cost effective, easy to apply & sustainable construction practices helps contractors save valuable time and cost in man hours, leading to faster delivery of projects.
