Superior quality project
Mongrain's service offering is the most complete in the industry and enables it to take care of the protection of all types of buildings, from foundation to roof, whether it is a new construction or a restoration. We collaborate with promoters and designers from the project’s first phases in order to offer sustainable solutions and we support them until delivery.
Adequate foundation protection is essential to prevent water infiltration, the presence of moisture and the appearance of mold.
Roof and wall imperviousness
Using high performance sealing systems (watertightness membranes, caulking, sprayed polyurethane, etc.), we control the migration of air, water vapor or harmful vapors between two connected premises (interior-exterior or interior-interior), depending on the project’s specific needs.
We offer you innovative insulation solutions so that the interior of a building is comfortable at all times and that you can reach the highest performance standards in terms of energy efficiency.
Vapor barrier and air barrier
After analyzing the building’s characteristics, we recommend the best products to effectively control the passage of air and humidity.
The high energy efficiency resulting from the judicious choice of insulation materials and methods has enabled Mongrain to become a leader in insulation in Northern Quebec, where the presence of strong winds always represents a challenge for the buildings’ airtightness.
Our insulation team’s vast knowledge is put to good use in every project we carry out and the best products (polyurethane, cellulose, etc.) are used.
Fireproofing reduces, controls or slows the combustion of flammable materials. Fireproofing products (fibrous materials, shotcrete, gypsum, etc.) are chosen according to the project’s specifications so as to increase the building’s fire resistance, which allows the structure to maintain its bearing capacity in the event of a fire.
Intumescent coating is a paint that creates a fire protection barrier. Applied in multiple layers, this passive protection is particularly useful for protecting the structures that one wishes to keep visible inside a building, in particular steel beams, thus offering up to 3 hours of fire resistance. It is one of Mongrain’s specialties, the company having carried out the largest intumescent insulation project in Canada to date.
The purpose of the thermal barrier is to protect insulating foam from fire.
The firewall is an obstacle used to limit the spread of a fire in a building. It can take the form of a partition dividing a vacuum or a door made of fire-resistant materials.
Asbestos and vermiculite removal
Used in construction until 1980 for its insulating properties, asbestos is now an undesirable which is sometimes difficult to remove from old buildings. Following an assessment of the structures to be decontaminated, we will offer you the safest method for removing the asbestos present in the vermiculite to be insulated, plaster and cement.
Mold affects the health of building occupants and that’s why we eliminate it safely, while ensuring that we make the necessary changes to moisture insulation in order to permanently remedy the problem.
Mongrain offers a wide range of products, materials and systems (panels, sprayed materials, fiberglass wool, etc.) to provide you with the desired acoustic attenuation and soundproofing depending on the type of building. We soundproof walls, studios or entire houses!
Structural protection aims to repair a fault in a building’s structure or in the concrete slab using carbon fiber, a highly resistant and very useful material when facing a lack of space or if we want to strengthen a portion following an addition. The carbon fiber is then insulated with non-combustible products. A turnkey solution to a complex problem!
