Joint Sealing
Giving floor, facade and building joints long service lives with systems that accommodate movement, withstand traffic and suit the conditions of use.
A floor ages at its joints; it is renewed there, too.
An industrial floor’s most vulnerable lines are its joints. A forklift wheel strikes the joint edge on every pass; a joint whose filler has failed first breaks its edges, then damages the floor around it. On facades and in buildings, a joint is an open invitation to water and air. Joint sealing looks like a small line item; in truth it is one of the details that define the life of the floor and the building.
The right sealant is selected for the joint’s duty: putting a rigid filler in a still-moving joint sacrifices the filler, and putting an unnecessarily elastic sealant in a dormant joint sacrifices the edge. In our applications we first understand the joint’s movement and traffic, then configure the sealant’s cross-section, its hardness and the edge repair accordingly.
- A sealant for the duty: Hardness and flexibility are selected for the joint’s real movement.
- Edge repair included: Broken edges are repaired to suit the system before sealing.
- Traffic resistance: Fillers that withstand forklift traffic and support the edge.
- Hygiene compatibility: Audit-ready joint solutions for food and hygiene areas.
On every surface where a joint is at work.
Joint sealing takes on different duties from floors to facades; the system changes with the zone.
Industrial floor joints
Filling the saw-cut joints of ground-bearing slabs.
Cold storage rooms
Sealants that keep their flexibility at low temperatures.
Food production areas
Joint details fit for hygiene audits.
Parking and ramps
Joints with vehicle traffic and water exposure.
Facade joints
Elastic weather sealing.
Wet room joints
Sealing joints in contact with water.

The sealant works at the right cross-section.
A sealant’s life depends on its cross-section geometry as much as its material; the backer rod makes the sealant work at the right depth.
- Joint sealantAccommodating the movement and the traffic, selected for the duty: the sealant.
- Backer rodThe bed defining the sealant’s cross-section and working depth.
- Primed edgesThe surfaces the sealant bonds to, repaired where required.
- Floor slabsThe moving concrete slabs the joint separates.
The right sealant for the duty.
The sealing system is selected for the joint’s movement, its traffic and the ambient conditions.
Semi-rigid fillers
Systems supporting the edge under forklift traffic.
Elastic sealants
Flexible systems for joints still in movement.
Hygienic sealants
Systems fit for food and cleanroom audits.
Edge repair systems
Rebuilding broken edges with high-strength materials.
What is expected of a joint sealant.
Movement capability
Follows the joint’s real movement without fatigue.
Edge protection
Supports the joint edge under traffic.
Chemical resistance
Endurance against cleaning and process chemicals.
Watertightness
A joint line closed to water and dirt accumulation.
Hygiene compatibility
An audit-ready, cleanable detail.
Fast return to service
An application opened to operations in a short time.
The scope follows the condition of the joint lines.
The classification below is indicative only. The final scope is determined by assessing the joints’ condition and traffic on site.
Joint sealing, or another system?
The source of the problem may sit under another heading, depending on the joint’s duty.
