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 less than 30% 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?

Lightweight

At 500 to 600 kg/m3, less than 30% of masonry, 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

Mixing Instructions

EnviroteQ is supplied in 100 litre bags for easy transport and installation on your building site. Preparing the product for use is straightforward:

  • Use conventional drum mixer
  • Place 20 litres water into mixer
  • Add 1 x 100 litre bag of EnviroteQ
  • Add additional 5 - 7 litres water
  • Mix for 3 minutes to a whipped cream consistency
  • To improve strength and water resistance (for applications such as shower floors), replace 10% of water content with a bonding liquid
  • After the completion of the surface finishing, cover with plastic sheeting for at least 7 days to prevent loss of moisture

Completed Projects

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

Our light concrete wall system has excellent compressive strength.

About SanteQ Lightweight Building Technology

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.
