    Maintenance of Concrete Expansion Joints

    June 23rd, 2017 Posted by Insights, Joint Sealing, Projects 0 thoughts on “Maintenance of Concrete Expansion Joints”

    FCS Concrete Repairs are fully resourced to provide maintenance and repair services for concrete Expansion Joints in commercial, industrial and residential properties.

    Expansion Joints in carparks and hardstand areas can also be repaired through permeation grouting of the sub-base to fill voids and polyurethane injection to lift the slab back to level where there is a step in the joint due to subsidence or washout. This process can avoid extremely costly and disruptive demolition and replacement of the concrete slab.

    FCS Concrete Repairs are experts in the field of concrete repair and are approved contractors for the major suppliers of joint sealants and joint repair products.

    You can rely on FCS Concrete Repairs, as we are Quality Accredited under the International Standard ISO 9001: 2015 to carryout quality workmanship with full backup services, if required.

    Expansion Joint Re-sealing

    Expansion Joints in concrete floors and walls control movement and over time the joint sealant can deteriorate. The sealant can be removed and replaced to ensure that the joint is waterproof and performs as required.

    Expansion Joint Reinstatement

    Expansion joints require that the facing edges of the adjoining concrete slabs are sound so that the flexible joint sealant forms a strong bond between the concrete slab or wall elements. Industrial floors, which may be on ground or suspended, require regular maintenance as they are vulnerable to impact damage from mobile plant including forklifts which are often hard-wheeled. Broken and crumbling edges along an expansion joints is an indication of future extensive and costly damage.

    Where considerable damage has occurred it may be necessary to carry out more extensive repair including concrete saw cutting and edge reinstatement. Regular inspection is a cost saving option to ensure that the jointing material is still performing and protecting the concrete joint edge faces. Heavy duty repair mortars may be required to re-construct the joint and these can be fast drying/curing to minimise downtime. FCS Concrete Repairs can provide professional advice in this regard.

    Widening Expansion Joints

    Expansion Joints may widen over time due to slab movement and damage.

    Narrow expansion joints can provide a smoother transition across the joint and minimise future damage. FCS Concrete Repairs can re-form wide expansion joints cost effectively to reduce the gap and the impact over widening joints.
