A durable joint starts with good preparation
The service life of a joint depends above all on its design and preparation: a width suited to the expected movement, clean and dry surfaces, and a backer rod that controls depth and prevents three-sided adhesion.
We select the sealant (silicone, polyurethane or hybrid) according to the specifications, the materials and the joint’s exposure.

Frequently asked questions
Your questions
Why install a backer rod?
The backer rod gives the sealant the right depth and keeps it from bonding to the bottom of the joint. The sealant can then stretch freely between the two faces, which prevents cracking and debonding.
Which sealant should be used?
It depends on the specifications, the materials, the expected movement and the exposure (sun, water, traffic). We follow the architect’s specifications and the manufacturers’ recommendations.
Do you restore existing joints?
Yes. We remove the old sealant, prepare the surfaces and install a new joint, on occupied buildings as well as heritage buildings.
Do you work for trade contractors?
Yes. We work for general contractors, masons and other trade contractors, as well as for managers and owners.
