Joint Sealing, Repair and Expansion

Properly maintaining pavement can add years to its life. Concrete expansion joint sealing, in which the concrete joint is cleaned and injected with a flexible sealant that allows the slabs to move, is vital to concrete maintenance.

Expansion joint repair must be done properly. If expansion joint sealing is not done correctly water, jet fuel, and glycol can seep through the cuts and damage the sub-base. The sub-base can become muddy and unable to properly support the concrete slab, resulting in more cracks and even breaks.

We understand concrete joint sealing and can create a seal that will move with the expansion and contraction of your pavement to prevent further cracking.

Expansion Joints Re-Sealing

Sealant life expectancy is typically 4 to 5 years. Once sealant fails water starts to seep into the concrete joint and will destroy the concrete/asphalt. Maintenance will avoid costly replacement. Call us and we’ll take a look at your pavement to see if it’s time for re-sealing your expansion joints.

A Revolution in Expansion Joint Repair: Chamfering

In cold climates, chamfering expansion joints protects the joint sealant and edges of the joint from damage caused when snow plowing. Sealant is recessed to the bottom of the chamfer, so snowplows or other traffic can’t rip out the sealant.

Chamfering greatly increases the life of the sealant, helping to reduce long-term concrete maintenance costs. In the last 5 years, we have chamfered the expansion joints on all airport jobs as the benefits of chamfering have become well known.

Interior Concrete Joint Sealing and Crack Repair

Whether inside or out, we use the same world-class methods and equipment for concrete joint sealing and crack repair. CanWest is experienced in warehouses, office buildings, parkades, malls, and more.

Doweling/ Drilling/Pinning Slabs

Essential for airport runways and taxiways as well as for road and highway construction, doweling, rock drilling and pinning slabs are three terms for anchoring concrete slabs together to ensure the slabs don’t move. First, a slot is cut across the joint to strengthen the slab. The panels are pinned together by inserting dowels along construction joints, and then epoxy is injected.

Panel Replacement

We are also experienced in removing and replacing sections of concrete that have been damaged due to a poor sub-base, excessive wear or cracking.
