The Robust Building System has far more benefits and advantages than any other Walling System

The “Robust Building System”, is a unique approved, durable, time saving and cost-effective building method to build sustainable structures that can withstand ‘forces of nature’ such as earthquakes, tornados, hurricanes, cyclones, floods, fires and termites.

Stronger

The strength of a Robust wall is far superior than conventional walling systems due its high lateral and load bearing capabilities.

Read More

Faster

The Robust technology lends itself to be a much faster walling construction method in comparison to that of conventional systems and provides quicker turnaround times.

Read More

Easier

The Robust Core wall panels weigh 3,6kg/m² and provides for a lighter structure that makes handling of these panels very easy, creating a better labour throughput.

Read More

Monolithic

The Robust walls fit together as a single diaphragm structure without any joints and seams that can cause structural interference normally caused by soil movement such as earthquakes.

Read More

Versatile

As with other innovative and/or alternative systems, Robust is not a modular system limited or restrained to a specific length or height. 

Read More

Affordable

Compared to other innovative, alternative and conventional building systems, the "Robust Building System" is more cost effective. 

Read More

Accredited

The Robust Building System has a proven track record and the system has been accredited and approved by various engineering and building councils, organisations and institutions worldwide.

Additional Internal Living Space

Although the Robust walls are more durable and has higher performance values than other walling systems, it is still thinner and thus creates additional internal living space in all types of buildings. 

Read More

Structural

The Robust Building System is a reinforced walling system that can be applied structurally by merely adjusting the wall thickness, steel and mortar requirements.

Read More

Permanent Shutter/Formwork

Robust wall panels create a backdrop for mortar to be mechanically applied. It creates an in-situ environment to build reinforced structural walls without having to use expensive shuttering or formwork.

Read More

Reduced Transport

Due to the system being lightweight and highly compact in its raw core form, 9,500m2 of wall core panels (34tons) fits onto a super link truck.

Greener - Low in Emission

Effective Transport leads to a huge reduction in Carbon emission and costs. Robust requires only 14% of transport in comparison with that of brick delivery statistics. 86% less in emission of fossil fuels.

Construction process using The Robust
Building System.

The Robust building system consists of conventional cast in situ concrete surface beds with thickened edge beams and thickening under internal walls constructed of factory produced expanded metal panels to which mortar is applied on both faces. Mortar is applied to panels mechanically. Mechanically applied mortar may be applied wet (pumped) or dry (gunited). Both faces of core are plastered. External walls are 115mm thick and internal walls 90mm. All other building material such as roofs, electrical, plumbing, window, doors, etc. are standard and conventional items.
Where the Robust System is to be used in the Southern Coastal Condensation Problem Area, insulated ceilings are installed in all cases and outer walls are 130mm thick and given an additional 15mm external finish of Pratliperl plaster. 

FOUNDATION

Generally, raft foundations are recommended for housing, although other methods may be used. Foundations and slabs are dug and filled with concrete, which can stand for a period of 24 hours before the frame is constructed. Demarcation of wall plan is done on the slab before erection of panels to ensure that all aspects of the structure, including internal electrical and plumbing installations have been carefully planned.

ROBUST WALL ASSEMBLY

Core is manufactured from Mild Steel Coils. Robust Core panels can be manufactured to any length up to 6,0m. The sheets measure 430mm in width with a weight of 3,55kg/m². Core panels are bound together by means of overlapping and securing panels with drywall screws. Bottom and top U-Channel tracks are secured to the core panels with binding wire and mesh reinforcing is applied to both sides of these panels adding strength and stability.

ROBUST WALL ERECTION

Damp proof membrane is applied on top of concrete slab on demarcated areas before wall erection can commence. The assembled wall panels are uplifted, erected and kept in place by means of Robust-jig supporting arms. The bottom rails are then secured to slab and all joining corners are squared, aligned and stabilized. Any conventional roofing system can be utilised with the Robust wall. To prevent the hassle of beam filling after roof assembly, roof trusses can be recessed into wall panels and secured by means of truss hangers or brackets.

APPLYING MORTAR & PLASTER

All electrical and plumbing required is easily installed in the natural V's of the W-shape (concertina) of the panel. The door and window openings are provided for by marking and cutting out the wall panel to the desired measurements for fitment purposes. After doors and windows are cut, a mortar mix is applied to all the external and internal walls by spraying it onto the reinforced steel mesh panels using the Robust Mortar Pump, designed for this purpose. When spraying the mortar, the thickness is measured to the outside diameter of the reinforcement fixed horizontally to panels. The sprayed walls are then plastered and finished off to resemble a conventional building.

FINISHED PRODUCT

The Robust Building System is adaptable to any door or window type. Steel doors and windows fixed in place before mortar application whereas aluminium and wooden doors and windows are fitted after mortar application. All finishes as per conventional brick & mortar systems are to client’s specifications. The architect’s drawing determines the overall style of the building. The finished product is not only sturdy and attractive, but the usable internal floor area is larger per m² than traditional built homes since the Robust walls are thinner than conventional building systems. The completed product in comparison with conventional plastered walls will look and feel exactly the same with one exception, it is thinner.

Tooling Requirement for the
Robust Building System

It is the assumption that contractors embarking on converting to the Robust Building System are well versed and familiar with conventional building and construction methods. Therefore, such companies will already have acquired all equipment to construct with. In addition, the following setup equipment is required to assist in assembling and erecting the Robust Building System Walls.

The Robust Mortar Pump is a Wet Mortar pump that can deliver a wet mix application of 1:5 @ 3m³/hour.
The pump consists of a peristaltic pump, generator, compressor, delivery hose and nozzle and a road going trailer.

a Vertical Binding Jig is required in the assembly of wall panels. The Vertical Binding Jig allows for wall panels up to 3,2m high and 6m wide.
It consists of 16 items that can easily be assembled and disassembled for ease of transport. 

Robust Building System Vertical Binding Jig

The Support Arm is a jig to secure and keep wall panels upright and in place during the erection process.
A support arm consists of 3 pieces - A Top Arm Cap, Support Arm and Floor Securing Bracket. Approximately 1 arm is required for every 4 lineal meters of wall.
