Joint width
Together with the expected movement, determines the required deformation capacity of the seal.
PolyShield Joints
Allow movement.
Keep water and damage out.

Q.AControllable execution
The joint as a technical detail
A joint is not a crack
which only needs to be filled.
A durable seal must be able to deform without coming loose from the flanks. This requires an appropriate ratio between width and depth, correct backing, reliable adhesion and a material that is suitable for water, traffic, chemistry, temperature and maintenance.
The choice of system starts with the function of the joint.Not with the tube that happens to be available.
AREAS OF APPLICATION
Not every seam moves the same.
That is why each joint type has its own assessment and detail route.
01Movement · geometry · elasticity
Expansion and movement joints
Joints that must accommodate thermal, structural or dynamic movement without loss of adhesion or uncontrolled tension.

Repair and sealing of seams in production, logistics and traffic zones, tailored to wheel load, cleaning and downtime.
View application ↗03Water · transition · adhesionConnection and bilge joints
Transitions between floor, wall, curb or material type where waterproofing and movement come together in one detail.

Six elements determine whether a seal can function sustainably.
Joint depth
A controlled depth prevents an unfavorable form factor and unnecessary tension in the material.
Back padding
Controls the depth, prevents three-point adhesion and supports an even sealing profile.
Joint flanks
Must be load-bearing, clean, dry and suitably prepared for reliable adhesion.
Movement
Thermal, structural or dynamic — the direction, frequency and magnitude must be determined in advance.
Tax
Water, traffic, chemicals, UV, cleaning and temperature determine the suitable system family.
Common causes of failure
Why a new sealant layer sometimes comes loose again.
Adhesion to both flanks and the bottom prevents free deformation and concentrates stress.
A profile that is too deep, too shallow or uneven changes the deformation and stresses the flank bond.
Dust, oil, old sealant residue or moisture block reliable adhesion, even with a good product.
A seal can only function when the expected movement remains within its capacity.
Hard wheels, concentrated loads and edge impact sometimes require flank repair or a different joint concept.
Primer, existing sealant, coating and cleaning agents must be mutually compatible.
Controlled from recording to release
Six steps for a verifiable joint scope.
Suitable for a separate jointing project or as a specialist part of a larger renovation.
- 01
Taking inventory
Record function, location, length, accessibility, damage picture and operating conditions.
- 02
Measuring and classifying
Assess width, depth, flank condition, movement, moisture and existing materials.
- 03
Detailed designs
Determine preparation, backing, primer, geometry and sealing material project-specifically.
- 04
Taste and preparation
Remove existing material, repair flanks and test adhesion in advance where necessary.
- 05
Controlled sealing
Apply backing, primer and sealant within the correct application window.
- 06
Release and register
Record profile, adhesion, finish, residual points and maintenance advice.
Business project scope
From one critical connection to a complete joint plan.
PolyShield Joints is intended for projects where continuity, watertightness, hygiene or mechanical stress are demonstrably important. We can inventory, classify and phase joints so that implementation fits in with maintenance windows and business processes.

Clear boundaries
When additional research is necessary first.
Cracks or flank damage with a constructive cause must first be assessed by the responsible specialist.
A leaking joint under water pressure may require an injection, drainage or specialized joint profile.
Cleaning agents, oils and process chemicals must be known before material selection.
A joint that is too narrow, irregular or damaged first requires repair, widening or an alternative detail.
Document your joint request technically
Photos and rough gauges are a good start.
Share location, joint type, damage picture, overall length, usage load and desired planning. We indicate what information is still required and whether a recording, trial or targeted quotation is the logical next step.
