Introduction to (I-BLOCK) & ICF

What is (I-BLOCK) and ICF (Insulating concrete Form)?

(I-Block) is the trade name for Insulated concrete form (ICF) technology which is a system of formwork for reinforced concrete usually made with a rigid thermal insulation
(EPS- Expanded Polystyrene foam) that stays in place as a permanent interior and exterior substrate for walls.

The forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete. The units lock together somewhat like Lego bricks and create a form for the structural walls or floors of a building.


Building with (I-Block) dramatically reduces the time and cost of construction and offers huge advantages in energy saving, fire safety, thermal efficiency and acoustic performance – and is also the greener, more sustainable choice.

This is expected to change the way of building in the whole region to Efficient Methods of Manufacture under the Code for Sustainable Homes.

I-Block construction is evident around the world in all types of buildings – apartment blocks, basements, offices, hospitals, schools, shops, hotels as well as housing.

A complete system

(I-Block) is the only complete Insulating concrete Form (ICF) system specifically designed for the Egyptian construction sector.

The supply and fit system includes all the elements required to construct I-Block walls such as bracing and alignment system and closers to seal the window and door cavities.

If you are a competent Contractor we can supply all the items required so that you can complete the

(I-Block) structure yourself. We can provide trained installation support to oversee your build, including architectural, structural and construction related areas.

Our trained installers can assist your build during critical build stages such as prior to, and post, concrete pours to ensure that you have no issues with your build.

Environmental choice

Our system enjoys excellent eco credentials in terms of environmental from a design approach that makes use of recycled materials wherever possible.

Through its thermal and air infiltration performance, (I-Block) construction can significantly reduce the ongoing operational CO2 emissions of buildings.

Structural performance

The (I-Block) Tech system consists of strong yet lightweight, interlocking forms made from flame retardant Expanded Polystyrene (EPS).

Once the forms are constructed the structure is filled with a Concrete to form a high performance monolithic concrete wall.

External finishes

An (I-Block) building can look like any other by applying plaster or mortar and Painting or adding brick slip systems, timber cladding, render or commercial cladding systems.

Whatever your project requires can easily be accommodated with our system.

Acoustic performance

Due to the density and thickness of the concrete cores within the (I-Block) Tech system, excellent acoustic insulation is provided.

STC at least 55 (fighter aircraft STC=60)

Cost effective

The (I-Block) system is around 10%-15% less cost than traditional house building techniques.

Our (I-Block) system achieves R-Value 26 with our standard form and can go down R-Value 55 using additional insulation, yet with a structural width starting from just 250mm.

High performance and still cost effective.

Egyptian Code design

(I-Block) have been used in the construction industry for more than 50 years mainly in the self-build markets particularly in the USA & Canada.

The (I-Block) system has been designed specifically for the Egyptian market, complying with Building Regulations and Standards, and of course, completely metric modular.

Volume house builders and smaller property developers can now benefit from the (I-Block) system, which is designed to be the ‘next generation’ ICF system delivering real benefits including design flexibility, thermal performance, ease of use, speed of construction and cost effectiveness.
