Joint & Crack Sealing

Joint Sealing

Joint sealing is a vital process in pavement maintenance.

The joints are cleaned and injected with a flexible sealant that allows the slabs to move. This prevents water, jet fuel, and glycol from seeping through the cuts and damaging the sub-base.

The flexible sealant moves with the expansion and contraction of pavement and prevents water from seeping down to the sub-base which makes the gravel muddy and unable to properly support the concrete slab. When this happens the concrete cracks and breaks.

Joint Re-Sealing

Sealant life expectancy is typically 4 to 5 years. Once sealant fails water starts to seep in and will destroy the concrete/asphalt. Maintenance will avoid costly replacement.

• Old sealant is removed by saw cutting out the deteriorated sealant and replacing it with new sealant.

Chamfering

Chamfering joints in cold climates protects the joint sealant and edges of the joint from damage caused when snow plowing is necessary. In the last 5 years all airport jobs we have done we have first chamfered the joints. Sealant is recessed to the bottom of the chamfer, thereby protecting it from damage caused by traffic such as snowplows, preventing the sealant from getting ripped out.

Chamfering greatly increases the life of the sealant, helping to reduce long term repair costs.

Interior Joint Sealing and Crack Repair

The same methods and equipment are employed to do sealing in warehouses, office buildings, parkades, malls, etc.

Crack Repair

Hair line cracks in concrete and asphalt can be repaired to prevent further more costly damage.

The cracks are saw cut or routed and epoxy is injected into them to seal them up and prevent them from lengthening or widening and to prevent any moisture seeping through and damaging the sub-base.

Doweling/Rock Drilling/Pinning Slabs

• Used to anchor concrete slabs together to ensure the slabs don't move
• A slot is cut across the joint to strengthen the slab. Panels are pinned together by inserting dowels along construction joints, then epoxy is injected.
• Essential for airport runways, taxiways and road and highway construction

Panel Replacement

Removing and replacing sections of concrete that have been damaged due to a poor sub-base, excessive wear or cracking.
