Discover Our Product Line for Foundations

Foundations are a core and essential element in the building architecture; they support and ensure the distribution of building loads. It is essential to protect them from water infiltration to avoid any damage that would subsequently have repercussions on the building structure. An unprotected foundation allows water to enter the concrete by gravity or capillarity. It is therefore vital to waterproof the outer face of the foundation rather than its inner face to prevent water from making its way into the concrete, then creating high humidity levels in the building as well as mould growth.

THE FLOODING PROBLEM

Did you know that floods are the most common natural disaster in Canada? In terms of costs, according to the Insurance Bureau of Canada (IBC), all levels of government in the country combined will spend more than $600 million per year to financially support the affected communities [1].

SOLUTIONS THAT MEET ALL NEEDS

No matter your project and your needs, RESISTO offers several materials to protect foundations, from dampproofing to waterproofing solutions; different options offering different levels of security and peace of mind for the occupant!

FOUNDATION COATING

This non-fibrous coating is a protection applied on foundation walls, footings, retaining walls, wing walls, abutments, and culverts.

  • Easily spray-applied or applied with a brush or roller
  • Protects masonry or concrete blocks
  • Prevents absorption and infiltration of humidity
  • Available in a low-temperature grade
  • Meets the basic requirements of the National Building Code in terms of waterproofing
  • Made of strong, durable HDPE
  • Composed of 85% recycled materials
  • Solves problems related to leaks in basements
  • Economical
  • Compatible with all substrates
  • Quick installation
  • Provides additional protection against cracks in concrete
  • CCMC certified: Protection against humidity (CCMC No. 12266-R)
  • CCMC certified: Drainage system (CCMC No. 12878-R)

BELOW-GRADE DRAINAGE BOARD

This dimpled high-density polyethylene (HDPE) membrane protects foundations. It creates a waterproof vapour barrier and an air space, which allow concrete to breathe while controlling moisture. The dimples placed towards the foundation create an air space that allows vertical draining of water towards the French drain.

SELF-ADHERED WATERPROOFING MEMBRANE

This self-adhesive membrane, composed of SBS elastomeric bitumen and tri-laminated woven polyethylene, is mainly used for foundation waterproofing.

  • Excellent adhesion to most substrates (concrete, masonry, and wood)
  • Increased resistance to tearing and puncture
  • Excellent elasticity allowing it to adapt to the movements of the structure
  • Self-sealing around screws and nails
  • Unparalleled durability
  • Available in a low-temperature grade
  • Meets the requirements of the National Building Code
  • CCMC certified: Foundation wall waterproofing (CCMC No. 13562-R)
  • Superior adhesion
  • Unparalleled durability
  • Excellent elasticity allowing it to adapt to the movements of the structure
  • No primer required on polystyrene surfaces due to its excellent adhesion strength
  • Available in a low-temperature grade
  • CCMC certified: Protection against humidity in ICF foundations (CCMC No. 14080-R)
  • CCMC certified: ICF foundation waterproofing (CCMC No. 13630-R)

ICF FOUNDATION MEMBRANE

This system, where walls are insulating and in which the concrete is poured, also includes the steel reinforcement necessary to strengthen the concrete walls. The ICF WATERPROOFING MEMBRANE is specially designed for this type of application. This self-adhesive membrane is directly installed on the forms once the concrete is poured, just like in a conventional system.

RECOMMENDATIONS

Did you know that it is necessary to use protective boards around the foundation in order to avoid damaging the membrane and to ensure the integrity of the waterproofing system?

Our SOPRA-XPS 30 extruded polystyrene insulation boards are perfect for fulfilling this function, in addition to insulating!

WHAT SETS US APART

Product Versatility

Our foundation waterproofing membranes can be used in a much wider operating temperature range than other products on the market. Therefore, they are more versatile and flexible, and they maintain thermal stability in all climate zones.

Release Film

Our silicone split-back release film provides better protection and longevity to sheet membranes, unlike paper-backed films that are more susceptible to tearing and failure in warmer temperatures.

Warranty

Our 20-year limited material warranty demonstrates our commitment to offering high-quality, durable and efficient products. You can be assured that the product you are installing has been tested and will perform exactly as intended.

FLOODS

FLOODS

The risk of flooding increases over time due to climate change on the one hand, and urban development on the other. Here are the main direct causes:

Hydrological dynamics of catchment basins

Precipitation

Runoff at snowmelt

Climate

Storm floods

Ice jams

Failure in the management of dikes and dams

IMPACTS OF POOR WATERPROOFING

Protective measures are intended to prevent soil moisture from being absorbed by concrete and transferred to the inside of the basement. They must therefore be properly applied to the exterior side of below-grade foundation walls to ensure adequate waterproofing.

Impacts of Soil Humidity Migrating into a Building :

  • Creating humidity on the surface and inside the walls;
  • Making a residence uncomfortable, even damaging to the health of the occupants;
  • Promoting mould growth, thereby altering air quality.

The waterproofing of houses is one of the solutions to reduce the health and safety risks associated with flooding.

DIFFERENT METHODS TO PROTECT AGAINST WATER AND HUMIDITY

HUMIDITY BARRIERS

Dampproofing is the treatment of a surface to make it resistant to the passage of humidity in the absence of hydrostatic pressure. It is considered as a barrier against humidity only. It offers no protection against water accumulation when the drainage at the base of the foundation walls is not functioning properly, and no protection against cracks in the concrete.

Waterproofing is defined by a perfect protection against water infiltration. It consists in treating a surface with a resistant, consistent and durable product to prevent the passage of water under hydrostatic pressure conditions.

PROTECTION AGAINST WATER INFILTRATION

NATIONAL BUILDING CODE REQUIREMENTS

Indeed, the National Building Code (NBC) only requires waterproofing the foundations in the presence of hydrostatic pressure on the foundation. Otherwise, only the minimum is required, namely dampproofing of below-grade foundations (Part 9 of the Code).
