Alternative Building Technology

Alternative building technology (ABT) is changing the face of construction in South Africa.

SanteQ is an Agrément SA approved lightweight walling solution for non-load bearing applications. This alternative building technology has a specially designed permanent shutter system with a composite lightweight concrete infill.

SanteQ's lightweight walling systems are easy to install and offer the permanence and peace-of-mind of masonry, with just 25 - 50% of the weight.

Why SanteQ Walling Systems?


At 550 to 1350 kg/m3, dependant on loadbearing or non-loadbearing walls, SanteQ delivers distinct design and engineering benefits.

Fire Resistant

SanteQ uses non-flammable boards and has a 2 hour fire-rating. The system does not give off toxic gases.

Sound Insulation

Air trapped in the infill provides 2 to 3x the sound insulation and noise reduction of a traditional wall.

Thermal Insulation

Polystyrene is an excellent insulator. By reducing heat transfer through walls, delivering 6x better R-value than conventional brick

Low Environmental Impact

100% recycled polystyrene, recycled plastic spacers, Fly Ash and cellulose fibre boards: SanteQ has among the lowest carbon footprints of any construction system.

Simple Construction

SanteQ is quick and clean to install and simplifies construction logistics, giving you predictable programme timing and reduced construction times.

Whether it's turning an old building into student housing or converting office space to accommodate a hotel, SanteQ has a proven ABT solution.

The SanteQ Difference

SanteQ's new alternative building technology offers lightweight walling that has excellent acoustic, thermal and fire-resistant properties.

Weighing less than 25 - 50% of conventional masonry walling, this alternative building technology is conveniently installed and utilises recycled materials to significantly reduce its impact on the environment.

The SanteQ lightweight walling system is a patent-pending construction solution that uses alternative building materials. Our ABT uses a custom-made infill of cementitious materials and 100% recycled polystyrene in a permanent high-density cellulose fibre board shutter system.

Urban Rejuvenation: Alternative Building Materials & Technologies

The surge in urbanisation, rejuvenation of existing older building, ever-increasing utility costs and growing awareness about environmental issues mean that many South Africans are considering alternatives to brick and mortar.

With the recent drive to restore, rejuvenate and regenerate old buildings, particularly in Sandton and the CBD, an exciting trend is gaining traction using ABTs in construction.

Future buildings need to be fit for purpose. This means that all broad and specific objectives, needs and uses of the building as well as its occupants need to be considered. This extends to building materials and construction methods.

SanteQ structural insulated panels provide high quality building materials and easy to use concrete forms for builders.

SanteQ Lightweight Building Technology

Our cementitious technology has a wide range of applications and is available in 100-litre bags, with 10 bags providing 1 m3 of concrete with a cured density of 500 to 800 kg/m3 dependent on your application.

There is a growing need to move away from building on-site. Some alternative building methods utilise modular design and off-site manufacturing. Off-site builds allow for faster, safer, environmentally friendly, and more cost-effective construction.

About SanteQ Lightweight Building Technology

SanteQ specialises in sustainable lightweight building technology. We offer a bespoke range of lightweight ABT walling systems that:

  • weigh significantly less than conventional masonry walling,
  • are solid, simpler, quicker and cleaner to erect,
  • significantly cut down on building times and
  • tick the acoustic insulation, thermal insulation, fire-resistance and green building boxes.

We also offer perlite as a lightweight aggregate replacement and as an insulating loose infill material for cavity walls as well as recycled polystyrene lightweight concrete in various strength and density classes.

SanteQ Lightweight Building Technology is a co-development by Sanjo Fabtech Sterling (a wholly owned subsidiary of Sanjo Construction) and CemteQ Building Solutions.

Sanjo Fabtech Sterling was formed to offer a patented, ground-breaking Alternative Building Technology (ABT) which utilises a permanent formwork system for load bearing applications. Realising the need for a lighter-weight alternative for non-load bearing walls, Sanjo Fabtech Sterling partnered with CemteQ, a leader in smart, sustainable cementitious technology, to develop a new cementitious infill that is lightweight, insulating and fire-resistant and SanteQ Liteweight Building Technology was formed to offer lightweight solutions to the construction sector.
