Concrete blocks are used as building materials providing excellent insulation, being highly heat and fire resistant. Terrazzo manufactures blocks in various sizes and shapes to enable consultants to offer endless design options to the customers.

TERRABLOC Blocks specifications are :-

  • High Load Bearing
  • Fire Resistant
  • Excellent Sound Insulation
  • High Thermal Efficiency
  • Energy Saving


Hollow blocks are precast masonary units made out of homogeneous concrete mix, likely to have two hollow cavities which reduce weight and improve insulation. The use of block work allows structures to be built in the traditional masonary style with layers or courses of overlapping blocks. These cement hollow bocks are widely used for building infrastructure and require low maintenance. High dimensional accuracy and consistent finish make these blocks an ideal building material in the construction of both load bearing and non-load bearing (partition wall) structures. Our cement hollow blocks are supplied to clients after being tested on various parameters. These concrete hollow blocks are a better substitute to work expeditiously as well as building a structure of long lasting value.


Solid blocks are extremely durable and well suited for general building works. These products are designed to meet and exceed all current and future regulations and are manufactured using the very latest production technology, in the most technologically advanced plant in the region. Solid blocks are manufactured with crushed aggregates, sand and cement and are commonly used for foundation of structures. Solid blocks are produced using ordinary Portland cement or sulphate resistance cement according to the requirement of customers. In addition to their load bearing capabilities, they provide a solid surface for plastering and rendering. They never disintegrate, providing a lifetime of trouble free performance.


Hourdi blocks are concrete building blocks with hollow cavities made using normal weight aggregates and are primarily used as filler in the construction of ribbed slabs. On special request, cellular types can also be made. Houdi blocks are manufactured with crushed aggregates. They are multi utility masonry blocks, which are getting more and more popular these days. They are suitable to withstand extreme climatic conditions. Hourdi blocks are used in the slab floor concrete. They are also known as filler blocks. Hourdi blocks are resistant to fire, different weather conditions and ageing. They have wonderful sound and thermal insulation capability. TERRABLOC produces all standard sizes and shapes of hourdi bocks according to the requirements of the customers.


Thermal insulated blocks are made of concrete consisting of selected aggregates and cement with extruded polystyrene of density 25 kg/m3 , which is specially designed and placed symmetrically, is integrally locked into the concrete structure resulting in excellent thermal insulation and bonding.

Advantages of using thermal blocks are as follows:

  • Excellent insulation because of the absence of thermal bridge between the two sides of the block.
  • The integrally bonded expanded polystyrene creates efficient thermal barrier.
  • Environmental friendly CFC free polystyrene inserts provide good sound insulation.
  • Polystyrene acts as excellent vapor and moisture barrier.
  • Thermo block can save electricity costs by over 50%.
  • Thermal modulation is reduced, leading to reduced demand on the air conditioning system.
