Eco-block Option

ecoblockConstru Casa has recently added the option to build using eco-friendy blocks from Interblocker.

These eco-friendly blocks:

  • Are made of 95% clay and sand and 5% natural binding agglomerates.
  • Are completely non-toxic.
  • Have no cement nor have to be in the oven to be cured, instead they are heavily pressed for strength and shape.
  • Utilize an interlocking shape to enable interconnecting without the use of cement motar. 
  • Have stronger compression strength (65 kg/cm2) than the standard concrete cinderblock (35 kg/cm2).
  • Allow tubes and electrical wiring to be hidden in two holes. Aside from this they are a solid block. 
  • Regulate the inside moisture levels in a house better than concrete, so a house stays drier in wet periods and condesation of water in the house is prevented. 
  • Are fungus-resistent due to high block PH levels (between 7 and 8,5). 
  • Provide better sound-proofing than hollow Cinderblocks due to their solid structure.
  • They are natural regulators of warmth and cold.
  • Are bullet proof. A nine mm bullet is unable to penetrate an ecoblock.
  • Visually appealing.

June Newsletter 2017


Last month we were delighted to welcome back Simone Kenny from Australia. Simone has been a serial organiser of volunteer groups for ten years. This time she came with a great group of friends that all donated to, and joined in to help us build two, 3 room houses in San Felipe close to Antigua.  It was always going to be a challenge to get both houses completed in the six days they were here, but these Aussie muckers made it look easy! We are also delighted then that Simone will be coming again in January with a huge group of 35 students from Eltham College in Melbourne. They will continue working in the remote community of Hacienda Vieja that her previous group from Eltham started last year. We can't wait for that! Thank you Simone, and thank you to all your amazing volunteers!
