Reduce Capex*

Preliminaries and General (P&G) includes the overhead costs of a construction project on site, generally between 5-15% of the Contract Sum. The industry norm is that 90% of Preliminaries are time-related (with the balance forming part of value and fixed portions). A time saving of up to 30% on P&G’s is possible.

Optimise Opex**

Reduce financial outlays

  • Up to half construction time
  • Generate rental revenue faster
  • Improve cash flow automatically
  • Reducing site holding costs such as rates and taxes
  • Reduce loss of interest on capital land and building investment and/or interim interest on bonds

Lower running costs

  • Inherent thermal properties dramatically reduce heating and cooling costs
  • Scientifically tested for heat retention in extreme Norwegian cold conditions
  • In African conditions, Selcrete™ keeps buildings cool in hot climates

Increase the lettable Area

  • Selcrete™ Block Wall has a width of 150 to 200mm. Traditional external brickwork typically 230mm inland and 280mm coastal
  • Gross internal area space increased or smaller external footprint achieved with similar internal dimensions
  • Essentially reducing construction costs per m²

*Capital Expenditure pre- and post-construction
**Operating Expenditure

Superior thermal performance

Selcrete™ 200 mm thick walls deliver a total R-value of 2.14 m²K/W:

Reducing allowables such as glazing i.e. when building with Selcrete™, double or Low-E glazing can be replaced with single glazing on certain elevations

Further savings include smaller, less costly HVAC systems; with a smaller unit delivering the same effectiveness as a larger unit in a traditionally built environment


1. Does Selcrete™ comply with National Building Regulations?

Yes, Selcrete™ is currently registered with Agrément South Africa (Certificate No. 2015/504). In Scandinavia, our Selcrete™ business partners are registered with SINTEF.

2. Are there any disadvantages of Selcrete™ versus traditional materials?

Selcrete™ offers numerous advantages over traditional materials such as cost-reduction and timesaving, greener footprints, safer, more lightweight etc. The one disadvantage is that loadbearing structures are currently only approved to three storeys.

3. Is Selcrete™ a green building material?

Yes, Selcrete™ is registered with the Green Building Council of South Africa (GBCSA) and delivers the following green properties:

  • Fungi and bacteria resistant; insoluble and non-hygroscopic
  • Lower carbon footprint, reduced impact on the environment
  • Less non-recyclable waste
  • Rodent-proof
  • Low maintenance
  • Constant insulation for the full service life of the building as does not deteriorate with age
  • Durable
  • High sustainability
  • Enhances green building values

4. How does Selcrete™ compare to traditional construction materials in terms of: Cost? Thermal insulation? Acoustic properties? Fire rating?

  • Cost?

The material costs of Selcrete™ are on par with traditional materials; however the real cost saving is in ease of erection, accelerated construction process, economies of scale and improved revenue flow

  • Thermal insulation?

Selcrete™ has a much higher R-value than traditional materials like clay bricks and concrete. It also reduces lateral leakage, cold bridging and condensation

  • Acoustic properties?

Sound absorbing and deadening characteristics are on a par or exceed that of traditional materials

  • Fire rating?

Selcrete™ currently has an Agrément approved 30-minute fire rating (60-minute fire rating pending)

5. Is Selcrete™ suitable for building higher than a single level?

Yes, subject to a rational design per project, Selcrete™ can be used within a multi-storey environment. Selcrete™ has been successfully implemented in three storey self-supporting buildings. Selcrete™ is also a great nonloadbearing infill wall material for both new and existing structures in multi-level construction.

6. How quickly does Selcrete™ cure?

Selcrete™ products can be stripped and erected within 48 hours of production. In-situ surface beds and slabs can be walked on within 24 hours.

7. Can I leave Selcrete™ exposed or does it require a finish?

Selcrete™ walls should be plastered and painted; all in accordance with Agrément Certification.

Slabs and surface beds require the application of a screed and specified floor finish.

8. How does Selcrete™ accommodate services like electrical and plumbing?

First fix chasing can be effortlessly carried out using a simple Stanley knife. Plus, Selcrete can implement first fix items within panels within the factory environment.

9. Are there any special requirements for fixings e.g. screws?

Light- and medium-weight fittings with a max of 23kg can be fixed onto the walls. All other fittings must be floor mounted. Special fittings are advised for wall-mounted applications – please call the head office to discuss your requirements.

10. How do I become an approved Licensee?

Apply to Selcrete™ South Africa. Qualifying and approved applicants pass through a theoretical and practical training requirement and there is a once-off payment to Agrément South Africa. Stringent quality control forms an integral part of Licensee requirements.

11. Is anyone able to build with Selcrete™ blocks?

To adhere with Agrément Licensor requirements, it is necessary for all approved Licensee staff to be skilled up to work with the product.

12. Where and how do I purchase Selcrete™?

In South Africa, Selcrete™ is currently available in Gauteng, Western Cape and KZN. We are implementing plans for rollout within the various SADC regions. Please contact us with details of your requirements.
