Floor Expansion Joint Repairs

Concrete Floor Expansion Joint Resealing

Floor joints act as a controlled cracks in concrete slabs and are positioned to allow the floor to move. Shrinkage from drying and thermal changes over time are the main causes of floor joint movement. Diamond Grind uses rigid concrete sealants that provide support and protection with the facing edges yet are flexible enough to accommodate the opening of the joint and remain bonded to at least one face.

Due to movement, joints are often the primary source of maintenance and repair for industrial and warehouse floors with the facing edges of joints constantly vulnerable to damage from hard-wheeled mobile plants and equipment. Joints with crumbling edges are commonplace in most industrial and warehouse floors and should be seen as an early indication of more serious long-term damage. Because of that, it is important to contact us as soon as you suspect there is a problem with flooring in your commercial property to prevent bigger issues.

By resealing floor expansion joints, Diamond Grind can reduce and even prevent further concrete edge crumbling thereby eliminating the need for expensive remedial work in the future. Joint resealing is a relatively simple repair however, the process works best when the edge damage is detected early. If more serious damage has already occurred, reconstructing the joint may be required. (see opposite).

The Problem

Mobile plant traffic impacts remaining ‘soft’ edges and sealant causing further crumbling of facing edges.

The Solution

Damaged joint is reduced by introducing a semi- rigid joint sealant. Mobile plant now transition from surface to surface smoothly.

Concrete Floor Expansion Joint Repair

Early detection and repair of damaged floor expansion joints significantly impacts the overall maintenance cost of a commercial floor. The joint sealant should be inspected regularly to ensure it is still performing adequately by protecting the joint edge. We offer regular checkups that will prevent costly and time-consuming repairs.

Once the damage has progressed past the scope of re-sealing the joint, it becomes necessary to reconstruct the facing edges. This should be done using a heavy-duty fast-cure repair mortar designed for industrial floor use. While cement materials are less expensive, they are brittle and ultimately fail to become costlier in the long run due to the need for continual repair.

A wide joint increases the risk of edge deformation and fracture caused by the deflection of the joint sealant under load. Consequently, it is important to minimise the width of the joint opening at the surface level. Diamond Grind’s method of repair allows for a 50mm wide ‘traditional expansion joint’ to be replaced with a neat 5mm wide, fully sealed saw cut. Each repair is ground flush with the adjacent floor surface to ensure that wheeled traffic smoothly transitions over the repaired joint.
