Joint Sealing Oakville

We survey the joint network, record widths and edge damage, identify active leaks and movement, and confirm whether failed concrete nosings or joint hardware require repair before resealing. Old material is cut and removed without damaging joint faces. Sawing, grinding, abrasive preparation, and vacuuming produce clean, dry, parallel bonding surfaces at the specified depth.

The governing document set is applicable OPSS requirements for civil joints, the 2024 Ontario Building Code, project joint schedules, approved product data, manufacturer preparation limits, and consultant adhesion-testing requirements. Width-to-depth ratio, minimum and maximum depth, primer, backer diameter, installation temperature, and cure-to-service time follow the approved system data and project specification.

The price responds to joint length and width, removal difficulty, edge repairs, substrate moisture, sealant chemistry, access, traffic control, temperature protection, primer, backer, and required cure window. Opening traffic before cure deforms or tracks the sealant. We define realistic closures, use suitable cure chemistry, and maintain protection until service criteria are met.

The controlling schedule factors are joint preparation rate, edge repairs, dry weather, substrate temperature, primer and sealant cure, traffic closures, access, and coordination with washing, coating, or paving. Old material is cut and removed without damaging joint faces. Sawing, grinding, abrasive preparation, and vacuuming produce clean, dry, parallel bonding surfaces at the specified depth.

Yes. We divide floors, facades, or pavements into short closures, maintain alternate routes, control odour and dust, and return each zone after the specified cure period. Opening traffic before cure deforms or tracks the sealant. We define realistic closures, use suitable cure chemistry, and maintain protection until service criteria are met.

We check joint dimensions, surface cleanliness, backer depth, primer use, batch and weather conditions, sealant continuity, tooling profile, adhesion test results, cure protection, and repaired edge condition. Sealant selection considers movement capability, hardness, tear resistance, fuel or chemical exposure, immersion, ultraviolet exposure, temperature, traffic, cure mechanism, and compatibility with concrete or adjacent membranes.

Provide joint plans or measured lengths, typical width and depth, substrate and exposure, photographs, existing material, leak or movement history, traffic loads, access, closure limits, and finish requirements. Old material is cut and removed without damaging joint faces. Sawing, grinding, abrasive preparation, and vacuuming produce clean, dry, parallel bonding surfaces at the specified depth.

Loss of adhesion usually points to contaminated or damp bond faces, missing or incorrect primer, installation outside temperature limits, early movement, or a joint geometry that places excessive strain on the bead. A field adhesion test and removal review are more useful than applying another surface layer.

A thin cap over failed material is rarely a durable repair because it cannot establish the required bond area or movement profile. Existing sealant and incompatible residue normally must be removed, the faces prepared, and new backing and sealant installed to the approved geometry.
