EnviroteQ Lightweight Concrete

EnviroteQ is a pre-blended, lightweight concrete mix consisting of cement and 100% recycled polystyrene with a special admixture coating. As durable as concrete, but 25 - 50% of the weight, this innovative building technology is ideal in a wide range of applications, including:

  • Void filling
  • Surface levelling
  • Lightweight screed
  • Insulating screeds
  • Insulation on roofs


Why EnviroteQ Lightweight Concrete?


At 500 to 1300 kg/m3, EnviroteQ delivers distinct design and engineering benefits.

Thermal Insulation

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

Fire Resistant

EnviroteQ lightweight concrete has a 2-hour SABS fire rating, and does not give off toxic gases.

Sound Insulation

Air trapped in the concrete provides 2 to 3x the sound insulation and noise reduction of traditional cement.

Low Environmental Impact

Using 100% recycled polystyrene and GGBFS, EnviroteQ has among the lowest carbon footprints of any construction system.

Easy Handling & Installation

Lightweight, it is easy to transport and install. It can be pumped over long distances without altering its physical or mechanical characteristics.

From a light concrete wall to a lightweight slab, EnviroteQ lightweight reinforced concrete is an innovative construction medium.

EnviroteQ is a high-quality, asbestos-free cementitious product that is both versatile, and environmentally sustainable. 

Resistant to weather, fire and water, EnviroteQ also offers the following advantages:

  • Does not shrink during application or curing
  • Provides total dimensional stability of the mix over time, ensuring screeds do not crack or swell
  • pH-controlled and non-corrosive, ensuring the mix does not react with other materials
  • Meets required insulating performance standards

Completed Projects

Construction companies are using SanteQ alternative building technology to build high-quality, lightweight walls quickly and easily.

Hotel Sky Royal


This 6-storey office building in Sandton was converted into a 450-room hotel using SanteQ's lightweight walling.

Cipla Pharmaceuticals


Cipla Pharmaceuticals rebuilt its manufacturing facility with 1 800 m2 of SanteQ walling.

Fredman Drive


An existing 6-storey office building in the heart of Sandton was gutted to a bare shell for conversion to luxury apartments.

Social Housing


Lightweight walling technology delivered 500 social housing units in solid
four-storey ‘walk-up’ blocks.

Kopanong Hospital


The project comprised 10 blocks each with around 2 000m2 of walling and a total of 2 000 m3 of EnviroteQ 600D concrete.
