The system

Out from a leading edge design and concept and using the highest guidelines and quality standards, the ISO-SLAB system is an advantageous and easy solution for the construction of an insulated slab-on-grade.

The usage of the ISO-SLAB system is applicable for all types of residential and commercial construction.

The key features and differentiators of the ISO-SLAB system are:

• The use of high density EPS polystyrene components with superior insulating capacity;

• The availability of two reference configurations (12 '' and 14 '') enable to meet load requirements, depending on the nature and type of project;

• The usage of an extension skirt surrounding the perimeter, compared to other construction techniques, enables to significantly increase frost protection;

• Easy assembly of prefabricated components;

• The ability to easily host the required reinforcing steel wire mesh, as required for the considered load, and allow easy integration of additional components for plumbing and heating.

The following provides further technical detail over an ISO-SLAB 12" installation

Natural soil without vegetation and leveled.
6" of 3/4" gravel for drainage.
ISO-SLAB 6" expanded rigid foam (R24).
Concrete slab (9" perimeter and 6" center) with wire mesh.
ISO-SLAB 12" module.
ISO-SLAB insulation skirt for frost protection.
Topsoil and turf.

The following provides further technical detail over an ISO-SLAB 14" installation

Natural soil without vegetation and leveled.
6" of 3/4" gravel for drainage.
ISO-SLAB 8" expanded rigid foam (R32).
Concrete slab (12" perimeter and 6" center) with wire mesh.
ISO-SLAB 14" module.
ISO-SLAB insulation skirt for frost protection.
Topsoil and turf.


The ISO-SLAB system brings upon multiple advantages and benefits within your project.

Cost and timeline reduction

  • Usage of the ISO-SLAB system brings upon significant savings in time and construction costs compared to a conventional approach by reducing the usual steps (excavation, formwork framing, formwork removal, filling, compacting and leveling).
  • In addition to significantly reduce excavation and work site preparation, the ISO-SLAB system eliminates the need for materials and labor related to formwork activities compared to a conventional approach.
  • Through its design and configuration, the ISO-SLAB system enables optimal use of concrete and reinforcing steel, bringing significant cost reductions in your overall project.


An overview of potential savings with the use of the ISO-SLAB system.

  • Total cost of construction 75%

  • Excavation 70%

  • Filling 100%

  • Footing 100%

  • Frost protection wall 100%

Easy installation

  • The ISO-SLAB system comes with all necessary components, ready for assembly according to the configuration of your project. If necessary, the adjustment of certain components is easily done on site with basic cutting tools.
  • Easy installation of a metal belt perimeter (supplied with ISO-SLAB system) ensures the integrity of the assembly and provides a mechanical connection between the modules of the perimeter.
  • The components included are lightweight and easy to handle therefore, requiring a minimum of manpower, both for the reception and for installation of the ISO-SLAB system.
  • The implementation of the ISO-SLAB system only requires basic knowledge on standard construction techniques. In addition, the ISO-SLAB system includes a detailed guide to the various stages of preparation and installation.

Compliance and performance

  • The ISO-SLAB system is designed to meet the elements of structural compliance and frost protection, applicable to obtaining an engineering seal on a final construction blueprint.
  • The insulating qualities of the ISO-SLAB system increases capacity to regulate the temperature inside the building, through better use of the available thermal mass and passive solar energy and the installation of radiant heating.
  • A pledge to quality and performance, the realization of a project with the ISO-SLAB system collects 17 of the 65 points required for LEED certified projects.
  • Usage of the ISO-SLAB system eliminates the risk of moisture, radon concentration, flood and mold often associated with conventional constructions.

Flexibility and adaptability

  • The availability of two configurations (12 or 14 inches) provides the flexibility to adequately respond to all types of residential or commercial projects, simple or complex, with different configuration features and variable surfaces.
  • The ISO-SLAB system is a proven construction system, adapted to the cold climate and for all types of terrain.

Environmental impact reduction

The use of the ISO-SLAB system can significantly reduce the construction footprint, as well as limit the environmental impact in several respects.

  • Associated to qualification standards relating to LEED certification, the use of the ISO-SLAB system and the absence of conventional excavation eliminate the need for heavy machinery on the site and limits the environmental impacts related to groundwater and damage to the surrounding vegetation (trees and roots).
  • The expanded polystyrene (EPS) used in the ISO-SLAB system, compared to the extruded process (XPS), contributes to the reduction of greenhouse gas emissions, both in its manufacturing and its continued use (secondary emissions). It thus provides a healthier living environment.
  • All components of the ISO-SLAB system are recyclable.
  • Compared to an excavation and conventional construction approach, the use of the ISO-SLAB system significantly reduces construction waste generated by the construction site.

About us


With the increasing demand for buildings without foundations, the search for better performing and leading-edge building techniques and over 30 years of experience in the construction field by its founder, the ISO-SLAB system was designed, developed and perfected with the input and cooperation of an engineering firm and a leading polystyrene manufacturer.

To adequately meet the demands of different projects either residential or commercial, two configurations delivered in a kit were developed.

The ISO-SLAB system allows to build differently without foundations, a high efficiency insulated slab-on-grade, at lower costs and within a reduced timeline.

The use of the ISO-SLAB system with its superior insulation and optimal use of thermal mass, is ideal for projects with radiant floor.

ISO-SLAB is a Sectorial Partner and Corporate Member of ECO home!
