Solutions for expansion joint issues in flooring

Expansion joints in concrete flooring naturally degrade over time, much like other structural elements. As deterioration occurs, it becomes essential to treat the concrete joints promptly to halt erosion and repair and seal the affected areas, preventing further damage and potential safety risks.

Sealing concrete joints during the initial slab installation, although not a common practice, is highly recommended. Without proper sealing, intensive use of the floor can lead to joint failure, potentially compromising worker safety and operational efficiency in industrial environments.

At every project, we provide and recommend comprehensive joint repair and sealing solutions to prevent complications, improve durability, and ensure optimal performance for any industrial facility. Additionally, our advanced sealing techniques are designed to withstand heavy use and minimise maintenance needs, offering a cost-effective, long-term solution for businesses.

PROJECTS

References in expansion joint repair and sealing

We have proudly partnered with major companies across the UK, providing expert solutions for concrete joint repair and sealing. Explore some of our most successful projects below:

GREENLIGHT (Southampton, UK)
Floor area: 1,500 m² Challenge: The warehouse floor had extensive joint deterioration caused by years of industrial traffic and surface wear. Damaged and open joints were allowing further edge deterioration and creating an uneven surface that required refurbishment before the facility could continue operating efficiently. Solution delivered: BECOSAN® repaired and resealed approximately 2,200 linear metres of expansion joints, rebuilding damaged joint edges where required and installing durable joint sealants designed for heavy warehouse traffic. As part of the wider floor refurbishment, crack repairs, localised concrete repairs and surface preparation were also completed before the floor received the BECOSAN® treatment. Result: The repaired and sealed joints restored the continuity of the concrete floor, helping to protect joint edges from future impact damage while improving forklift traffic, reducing maintenance requirements and extending the service life of the warehouse floor.
SAINSBURY (Rugby, UK)
Floor area: 61,500 m² Challenge: Following more than 20 years of intensive warehouse use, the concrete floor contained numerous deteriorated expansion joints that had suffered edge damage and wear. Before the warehouse could be handed over to Sainsbury, the joint system had to be restored to withstand continuous logistics traffic and prevent further concrete deterioration. Solution delivered: BECOSAN® carried out a comprehensive programme of expansion joint repair and resealing across the warehouse, restoring damaged joint arrises and installing new sealants to protect the concrete from impact, dust and debris ingress. These works formed part of the wider floor rehabilitation programme, alongside crack repairs, removal of obsolete coatings and anchors, before the application of the BECOSAN® floor treatment. Result: The restored joint system improved the durability and functionality of the warehouse floor, providing smoother forklift movement while reducing the risk of further joint failure and costly future repairs. The complete rehabilitation was delivered within the project’s demanding 60-day programme, allowing the facility to be handed over on schedule.
