The Aertec approach combines competitive direct pricing with hands-on coaching and training, ensuring project teams realise the full performance benefit of building with AAC.

01 · What we do

Product, technical support, and site assistance.

Aertec supplies the full AAC system — blocks, panels (by special order), mortar, skim plaster and tools — using technology developed and proven internationally. Our products are manufactured in line with local and international standards supported with full technical data sheets.

Supply alone isn't enough. The Aertec package includes technical support throughout the project as well as on site assistance.

Transparent project pricing

Priced directly off your bill of quantities. No minimum order for residential projects. You see the full number before you commit.

Technical support included

Your engineer or architect can call us on a design-table query. Your site team can call us on a laying issue. Technical support is part of the supply relationship, not an add-on.

One supplier, one system

Blocks, mortar, plaster, and tools specified and supplied together as a matched system. One delivery schedule, one invoice, one point of accountability.

On-site team training

We coach your laying team on AAC methodology before the first block goes down. That means you get the full speed and waste-reduction advantage from day one on site — not after a learning curve.

02 · What is AAC

Proven in Europe for over a century. Now available in South Africa.

AAC was invented in 1924 and has been the dominant walling material across Europe, the Middle East, and Asia for decades. It became the go-to reconstruction material after World War II because it is faster to build with, at lower cost, and with better thermal and seismic performance than conventional masonry. This is why it now has a 60% walling market penetration in Germany and 40% in the UK.

The raw materials are sand, cement, lime, gypsum and water — widely available, non-toxic, and low CO2 impact compared with clay brick firing. This combination of natural raw material inputs and autoclaving in the manufacturing process is what gives AAC its green credentials.

On a South African project, that global performance record is now available with a locally supplied AAC product in accordance with EN 771-4 / SANS 50771-4 — with full data sheets, local technical support, and delivery from Cape Town and Durban direct to site.
