Products - Overview
The Durisol insulated concrete forming system (ICF) is a straight-forward method of building a reinforced concrete wall with built-in thermal, acoustical and fire protection. The wall forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete and reinforcing steel.
The Wall Form units are available in a variety of widths and insulation configurations that create a system that is flexible, design friendly and optimized for each specific application (above-grade, below-grade, commercial, residential, etc.).
Our thermal Wall Forms incorporate mineral fiber (rockwool) insulation that is also non-combustible, moisture resistant and positioned towards the exterior of the wall, resulting in additional energy efficiency that is not possible with other insulated concrete forms
Since 1953, Durisol products have been integrated in every type of building application. The inherent insulation value, the 4 hour fire rating, the ease and speed of building and the moisture resistant capabilities make the system unmatched for most building projects.
2. Leveling Shims – Since there is no mortar between the courses of Wallforms, it will become necessary to compensate for variations between individual Wallform units. It is recommended that every second or third course is leveled as you build, using any one of the following:
- Conventional cedar shims from your local hardware store
- Specialty plastic shims that may be available in your area
- Conventional masonry mortar- -Spray foam or construction adhesive
- Using coarse thread screws (deck screws) to screw the units
together (vertically and horizontally). Conventional nails can also be used.
3. Wall Reinforcing – The steel rebar schedule for each wall is
project specific and must be designed by a professional engineer.
4. Lintel Reinforcing – Steel rebar over openings is project
specific and must be designed by a professional engineer.
5. Concrete Fill – Typical Concrete designs range between
17 MPa – 25 MPa (2500 psi – 3600 psi) and use a max 3/8”
aggregate size. Download our construction specification
document for more information.
6. Lintel Wall Forms (made on-site) – Lintel Wallforms are created
on-site by removing the webs from a conventional Square End
unit ant turning the block 90 degrees so that the closed end is
on the bottom.
7. Square End Form – These units are used at the sides of
openings to prevent concrete from pouring out during construction.
These units are not always necessary and it is also acceptable
to use Standard units (without a closed end) in conjunction with
conventional wood bucks to frame the openings.

8. Corner Form – Corner Forms are specially notched to allow
the concrete to flow around the corner into the adjacent wall.
They measure 24” x 12” to maintain the desired 12” module.
Our 12” units are already 12” thick, so the Corner units are
made from a modified Square End unit.
Refer to our Product Dimensions for more information.
9. Insulation Inserts (Thermal WF) – All insulation inserts are
manufactured from rockwool mineral fibre insulation. We do not
use any polystyrene in our products whatsoever.
1. Optional Mortar Bed – It is recommended that the first course
of Durisol Wallforms be set in a 1⁄2” bed of mortar. It is also
possible to substitute mortar with other leveling materials,
if desired. This leveling bed will allow the first course to be set
perfectly level and make the construction of subsequent courses
easier, and faster. All other courses are dry-stacked (without mortar).
