MCG Construction is proud to now be offering a new, revolutionary wall system approach called the Strongwall Integrated Building System™. Since 1997 this system has been utilized globally in 1000’s of construction projects, representing all sectors. Strongwall eliminates the need for framing, insulating, and dry-walling. Panels are assembled using polyethylene base cement or an epoxy compound. Vertically integrated conduits greatly reduce the time to install utilities (i.e. electrical, plumbing, fibre cable etc.), thereby greatly reducing both construction time and capital costs. The Strongwall Integrated Building System™ works by joining panels by use of tongue and groove construction to strengthen the structure between the panel and its connected beams and columns. The result is an exceptionally light-weight, fully customizable construction system that is easy to transport, store and erect, saving both time and money. Benefits of STRONGWALL include:

Minimum Weight :

Strongwall Integrated Building System™ panels, are extremely light with no additional plaster being required. The finished product weighs less than 25 percent of a comparably sized block wall.

Hydro-stability :

Strongwall Integrated Building System™ panel composites, effectively resist both moisture penetration and the formation of surface condensates, that are common under humid conditions.

Greater Suspension Loads :

Strongwall panels support isolated suspension loads exceeding 47 kilograms, well over 100 pounds per wall-screw/nail.

High Fire Resistance :

Rated “Class A” under certified tests of 1,700 degrees Celsius or 3,092 degrees Fahrenheit. Tests conducted over 3 hours of exposure per side.

Optimum Vibration Dampening :

Due to the cellular polystyrene and cement composite structure, Strongwall Integrated Building System™ demonstrates high resistance to vibration-generated deformation and flange mounting strength. The result is a safer, more sound-resistant interior.

Energy Efficient :

Excellent heat insulation gives advantages of energy savings. The insulation rating for both severe cold and hot conditions reduces overall energy consumption.

Strongwall is a complete wall system developed using patented production processes, new architectural techniques and proprietary material compounds. The outer panels, or face plates are produced using a proprietary mixture of high-grade cement and polystyrene foam beads (“cells”), re-bar and fiber glass meshing with a pure white Portland cement layer on either side. The result is an exceptionally light-weight, incredibly strong, fully customizable construction system that is easy to transport, store and erect.

Are STRONGWALL homes more expensive than regular homes?

No. In fact, homes built using STRONGWALL are typically the same cost as wood built homes but provide a better equity upon completion.

Is the STRONGWALL product environmentally friendly?

STRONGWALL is Eco and forest friendly using 100 percent recyclable, non-hazardous, time-tested materials. Given the installation-ready nature of product, there is far less building site rubbish and environmental impact. Further, the energy-saving capacity of the product reduces energy use and is therefore climate-friendly.

How long has STRONGWALL been around?

For nearly 20 years, STRONGWALL has been distributed throughout Canada, Australia, the Middle East, Russia, and South East Asia.

Will my STRONGWALL home look different from the rest of the houses on my block?

No. Houses built with STRONGWALL look the same as most wood built homes.

How do you build a home using STRONGWALL?

The process in building a home with STRONGWALL begins similar to wood built but then transitions into our home build process, as follows:

  1. 1. Find design and complete architectural drawings
  2. 2. Permit application and approvals
  3. 3. Site survey
  4. 4. Foundation excavation
  5. 5. Foundation walls installation (concrete cure for 7 days)
  6. 6. Plumbing rough-ins
  7. 7. Basement slab prep and pour (concrete cure for 7 days minimum)
  8. 8. Basement STRONGWALL installation (if within contract)
  9. 9. Main floor slab prep and pour (concrete cure for 7 days minimum)
    9A. Customer walk through for visual inspection of product within basement only
  10. 10. Main floor exterior STRONGWALL installation
  11. 11. Main floor interior STRONGWALL installation
  12. 12. Second floor slab prep and pour (if within contract, concrete cure for 7 days minimum)
  13. 13. Second floor exterior and interior STRONGWALL installation (if within contract)
  14. 14. Roof Installation
  15. 15. Garage walls and roof (if within contract)
  16. 16. Window and door installation
    16A. Customer walk through for deficiencies
  17. 17. Interior finishing work (includes painting, flooring, millwork, etc.)
  18. 18. Exterior finishing work (includes stucco, landscaping, concrete, etc.)
  19. 19. Completion and turn over

*Note: At completion of each floor level, plumbing and electrical are phished through the integrated conduits and wall finishing occur
*Note: Exterior work may occur at any stage of the construction process

Is STRONGWALL insulated and what is the insulation value?

Yes, STRONGWALL is insulated. The exterior 8" walls carry an R-value of R-32, above the required NEB (National Energy Board) code amount of R-27.

Is the foundation made with STRONGWALL?

No, the foundation is the same as all homes and made with concrete.

What are the interior walls of my STRONGWALL home made of?

The interior walls are made of the same STRONGWALL material but in 4" and 6" thicknesses.

What are the floors of my STRONGWALL home made of?

All the floors are made of concrete.

What is the roof of my STRONGWALL home made of?

The roof is made of fire rated wood roof trusses.

What are the stairs of my STRONGWALL home made of?

The stairs are made of wood.

How do the walls of my STRONGWALL home connect to the floor?

The walls are dowelled into the floors using steel rebar spikes.

How do the STRONGWALL walls connect to the roof?

The roof plate is bolted down into the STRONGWALL.

What happens if this STRONGWALL structure is involved in a major fire?

The exterior cladding may melt or burn but the walls will remain intact with minimal
damage to them. STRONGWALL is rated “Class A” under certified tests of 1,700
degrees Celsius (3,092 degrees Fahrenheit) over 3 hours of exposure per side.

Is it possible to have in floor heating in a home built using STRONGWALL?

Yes, in floor heating can be installed prior to pouring the slabs.

What do I do if I want to renovate/add switches/do repairs after the STRONGWALL home is completed? How hard is this to do?

The work is very similar to cutting drywall and installing a new plug. Instructions can be provided if requested. A call to our offices can help you through this process.

Do you use drywall on the inside of the STRONGWALL home?

Drywall is used on the underside of the floors as well as the ceilings using 5/8" SHEETROCK Firecode Core (Type X) Drywall. This drywall offers additional fire-resistance over regular drywall materials.

What is the difference between the inside and the outside walls of my STRONGWALL home?

Primarily, thickness is the only difference between the inner and outer walls. all other features are the same.

Where is the electricity run in the STRONGWALL?

Conduits are pre-installed into the STRONGWALL walls

Where do the pipes for plumbing go in my STRONGWALL home?

Plumbing pipes will be cut into the walls as required and covered over by drywall and
mud/plaster. Plumbing pipes will be cut into the walls as required and covered over
by drywall and mud/plaster. This does not result in any loss of wall strength as these walls are not load bearing. The steel support beams carry all the loads of the floors with no weight being placed on the walls required for plumbing.

How do I hang photos in the STRONGWALL walls?

The best way is to pre-drill a hole into wall and then hammer your hanging nail/screw into the wall, similar to the way you would hang photos in a typical wood built home.

Why are the permits taking so long/why are there delays for my STRONGWALL home?

Permitting takes a little longer due to STRONGWALL being a relatively new product in the Canadian market. Additionally, because our homes are engineered, permit officers require more time to review drawings and details.

Why do I have to pay upfront, other builders don’t require that?

Upfront costs go towards the initial payments of the Strongwall material, the engineering process with architectural drawings, site surveys, and construction of the foundation. Wood built homes do not engineer their homes and therefore do not require upfront payments.

Will my STRONGWALL house be cold?

On the contrary, the home has a higher insulation value than most wood built homes as concrete absorbs heat keeping it warmer, longer.

Is STRONGWALL energy efficient?

The insulation rating for both severe cold and hot conditions has demonstrated the wall system reduces overall energy consumption. Excellent heat insulation gives advantages of energy savings. Demonstrated to be Thermal Non-Conduction ASTM C177: Evaluates thermal conductivity (insulated properties). Evaluation: Intertek ETL SEMKO Registered low thermal conductivity (high insulation values).
