How It Works

From foundation to wall - four stages

The Ecobrix system is straightforward. You don't need bricklaying experience. You don't need specialist equipment. You need to be able to follow a sequence - which we'll teach you.

01
Preparation

Lay your foundation

Ecobrix works with any standard foundation type. The first course of blocks is laid directly onto the foundation slab up to DPC level, set out precisely to your floor plan. This is your only critical accuracy stage - everything above follows from it.

02
Stack

Dry-stack the blocks

Ecobrix blocks are dry-stacked - no mortar, no levelling compounds, no specialist equipment. The blocks interlock and their own weight provides stability throughout the build. Works in all weathers, including below 0°C. Course by course, your walls take shape fast.

03
Fill

Pour ready-mix concrete

Once walls are stacked to the required height and reinforcing steel placed, a low-slump ready-mix concrete is poured to fill the hollow cores. The mix can be placed at temperatures that would halt traditional brick-laying. The concrete sets and the structure is complete.

04
Finish

Apply your external finish

Ecobrix accepts all standard external finishes - render, brick slip, brick, timber cladding, rain screen cladding. Chasing for electrics and plumbing is fast with a powered circular saw. All flooring systems and internal finishes are fully compatible.

FAQs

Common questions from self-builders

Do I need building experience to use Ecobrix?
No specialist experience is required. The dry-stack system is straightforward to learn. We offer free training days where you can practise before starting your build. Many of our customers have been first-time self-builders with no prior construction experience.
Will my building control officer accept Ecobrix?
Yes. Ecobrix is BBA certified and LABC technically approved - two of the most recognised standards in UK construction. Building control officers routinely approve Ecobrix projects across England, Wales and Scotland. We can provide full documentation and will support your application if required.
Can I achieve Passivhaus certification with Ecobrix?
Yes. Ecobrix achieves U-values of 0.15 W/m²K or below without additional insulation, and PSI values of 0.04–0.08 at all junctions. These values are compatible with Passivhaus certification. For very stringent targets, an additional layer of external insulation can reduce U-values further.
Can I build in cold weather?
Yes - this is one of Ecobrix's key advantages. A low-slump concrete mix can be poured at temperatures that would halt conventional brick and block laying. Work on Ecobrix builds has continued at temperatures as low as −4°C without product or programme impact.
What external finishes can I use?
Most standard external finishes are compatible with Ecobrix including render, brick, brick slip, brick render, timber cladding, and rain screen cladding. Internal finishes are unrestricted. If you have a specific finish in mind, contact us and we can advise.
How long does an Ecobrix build take vs traditional methods?
Significantly faster for equivalent projects. The dry-stack system eliminates mortar mixing, setting, and weather delays. A complete wall can be stacked in a fraction of the time of traditional bricklaying. Seven terraced homes were delivered from foundation to weathertight in just eight weeks at West Carclaze, Cornwall.
