NOW A VERY EFFECTIVE SEALING STRIP FOR CONCRETE JOINTS.
Established in Victoriaville, «STOPO» is a Canadian owned and operated company that is specialized in the fabrication of concrete construction joints and a polyethylene closed-cell expansion joint filler (STOFLEX).
STOPO makes these special sealing strips for concrete construction joints, made of a mixture of bitumen and polymer modified rubber, wrapped with stone aggregate (non- reactive with alkali-silica of Portland cement) that acts like a binder between the concrete and the sealing strip.
Embedded in concrete, these strips of high plasticity and malleability ensure full sealing of any void in concrete, and absorb any movement in concrete and joints, such as concrete shrinkage, as well as shear or tensile movement in joints. Think of their capacity to deform and retrieve under seismic vibration for instance.
They are inert and don't degrade whatsoever under fluid or temperature action. Embedded in concrete, the STOPO sealing strips material does not age. The sealing strips material presents good resistance to acids, salts and bases.
The STOPO TYPES 3 and L sealing strips, having at least one side without stone, may be heated and their resulting viscosity at the surface allow strong bonding to various hard surfaces such as concrete, steel, PVC and even bedrock, thus filling all roughness at the contact surface.
These types of sealing strips are very useful for various applications in concrete construction works, for new constructions and particularly for building over and against existing concrete foundations and walls.
