Why Monarc- about

About Monarc

Monarc is  New Zealands Leading Architectural Precast Concrete Brand.

The Monarc brand was established in February 2008 in Auckland New Zealand by Auckland's premier precast manufacturer Nauhria Precast.

The timing of Monarc's brand launch resulted in extreme challenges with the onset of the Global Financial Crisis (GFC) during this time Monarc proved to be a sought after product Fast growing and establishing itself to the architectural market as a preferred, desired and exciting product allowing Architects and Architectural Designers creative freedom to explore and realise their visions. 

The Investment in the latest International post-cast precast processing machinery, provided the mechanism for Nauhria to research and develop leading edge concrete Mix designs and to continually refine and improve both product and productions skills. Unique European casting techniques were introduced resulting in the best possible architectural precast products available to the construction market.  

Nauhria provide a niche product to the design industry, and Monarc has set new benchmarks in product quality and design capabillites. Monarc has helped to dramatically invigorate the architectural demand, originality and the desire for designers to achieve more from the amazing medium of precast concrete.

Made from locally abundant Aggregates, sands, cements  and oxides, Monarc's natural ingredients combined with the many processes of its manufacture result in a naturally harmonic product. Being organic in nature Monarc possess the many imperfections that remind us just how beautiful nature truely is.

Product Knowledge ...


Key Product Parameters :

  • Monarc panels must be a maximum of 3200 mm in either the panel height or panel width 

  • Maximum length is governed by transportation capabilities - typical transportation max length is 12 meters
  • Maximum Panel thickness for monarc processing is 450 mm overall
  • Maximum unit weight is 18 tonne (to meet production gantry crane capacity and transport standard load weight restrictions)
    NB. (over-dimension panels may be considered by discussion and may incur additional cost for specialised handling and delivery equipment)
  • No projecting bars or items from the face of the panel to be processed as these can interfere with the processing ability of the Monarc Machine and can restrict machinery movement. 
  • The Panel thickness is reduced by apx 5 mm per monarc processed face, Panels are cast 5 mm thicker per monarc face to accommodate this removal while maintaining the overall specified structural thickness.
  • It is standard practice that all Monarc panels are cast with 15x15mm chamfers to panel MF edges, The chamfer depth is often reduced with Monarc's surface refinement.
  • Window and door openings where possible should be a minimum of 600mm clear of panel edges.

Why Monarc-Bespoke

Creating bespoke designs with Monarc 

One of the beautiful thing about monarc for Architects and Designers is the creative freedom that Monarc provides.
With its multiple diamond toolings, Monarc provides unlimited design potential breaking beyond the barriers of catalogued product selection.

In order to create a bespoke design it must first be understood how the process of creation and production takes place. 

  • First Concrete colours must be selected, Panels may be cast with the colour full thickness or could adopt a minimum 40mm facing layer (additional thickness to any structural thickness requirements)

Precast panels are cast intended for further monarc processing as such adopt unique and critical casting methodologies to deliver an uncomparable aesthetic appearance.

  • Following the Casting and minimum curing time, (honing : 5 days, Brushing : 2 days, Hammering : 10 days) areas of panel coverage need to be defined and surface textured, This involves first Grinding back into the aggregate (apx. 3mm) then refining the defined area with the selected finishes or an F5 raw as-cast surface.

NB i - Precast panels are cast 5mm over thickness to accommodate the surface texture refinement while retaining the minimum structural thickness specified.
NB ii - Monarc's texture processing heads are 600mm in diameter and require a minimum area of 500mm wide, Smaller areas would require hand processing which can result in a difference in appearance. 

  • Following Surface Texturing Decorative Cuts, Mills, Routing or various combinations can be processed into the panel face.


MONARC Milling tools

  • Maximum Milling Depth is 15mm - This has proven to provide excellent contrast through natural light reflection & shadow.
  • Moanrc's milling wheels can process Straight lines to any angle.
    (curves can only be accomplished through casting in rebates or routing to a path)


MONARC Cutting tools

  • Cutting blades are 300mm +/- Diameter
    (NB. As the cut blade radius is 150mm, Cut formed rebates within the panel area will reflect the radiused entry and exit variable by the depth of the cut)
  • 5mm +/- cutting width
  • Maximum Cut depth is 15mm - 
  • Blades me ganged together to create Thicker Cuts resulting in a ribbed cut texture within the cut rebate (maximum 30mm Ganged Cut width)
  • Multiple blades may be spaced apart in a single cut pass using spacer plates, Maximum stacked tool width : 100mm wide.
  • Monarc's cutting blades can process straight lines to any angle.
    (curves can only be accomplished through casting in rebates or routing to a path) 
  • Examples of Blade configuration : 


MONARC Routing tools

  • Routing concrete is a slow process consisting of a spinning Diamond 'Candle' head tool'
  • Tools follow a stroke centre path line generated  via CAD Polyline data
  • Curves are converted to straight vector paths
  • Blocks of removal are processed with repeat strokes over lapped to carve out the selected area.
  • Note that Strokes and external corners end to the tool radius.
