From soil to brick

How to manufacture ecological bricks

Eco Máquinas offers the best manufacturing practices, with no firing and no harm to the environment. Learn every stage — from raw material to curing and storage.

The process in 4 stages

From earth to finished product

01

Raw material

Selection and validation of soil, waste or stone dust. The right dosage with cement defines the strength.

02

Mixing

In the planetary mixer or multiprocessor: crushes, mixes, sieves and moistens the mix evenly.

03

Pressing

The press compacts the mix at high pressure, forming interlocking bricks, blocks, floors and tiles.

04

Curing

The piece is kept moist for 3 to 7 days, depending on the cement, to reach full strength — no firing, no kiln.

Raw material

What becomes a brick?

The base is soil-cement — local soil mixed with cement and water — but Eco technology accepts a wide range of materials and waste:

Soil-cement Stone dust Ash Gypsum Bauxite Recycled debris Organic waste (Konlix) Foundry sand
Critical stage

Curing methods

Curing ensures the brick’s final strength. It must start right after pressing and continue for 3 to 7 days, depending on the cement, keeping the piece always moist. In every method the bricks are covered with plastic film after stacking. Choose the method to fit your setup:

Manual curing

After stacking, the pile of bricks is wrapped in plastic film, retaining the piece’s own moisture. Practical and economical, no daily watering needed.

Series production

Spray curing

Wet the pieces several times a day (or with automatic sprinklers), keeping the surface always moist throughout the curing period.

Covered yards

Immersion curing

The pieces stay immersed in a water tank for about 30 minutes — or until air bubbles stop rising from the water. Ensures full, uniform hydration, ideal for high-responsibility pieces.

Storage and stacking

How you store directly affects final quality. Follow best practices to avoid losses:

Straight from the machine to the pallet: bricks come out pressed and are already stacked on the pallet they stay on until they reach the customer.

A covered, dry place sheltered from wind — draughts dry the piece out and cost moisture — protected from rain and direct sun, on pallets or racks, never straight on the ground.

Stacks of at most 5 crossed courses for stability and to avoid cracks in the bottom pieces.

Separate by batch and manufacturing date to control curing age and stock rotation.

Brazilian standard ABNT requires 28 days for full curing. In practice, most builders use the bricks right after moist curing — 3 to 7 days, depending on the cement.
