Floor Joints

Floor Joints and Movement:

Floor joints are constantly exposed to stress and movement caused by expansion, shrinkage, vibration, and temperature changes. This is especially true in high-traffic areas like warehouses, production halls, car parks, and shopping centres, where joints must absorb dynamic loads from vehicles and foot traffic. A great example of this is the Christchurch Stadium project, where a double-seal solution was used to handle sustained movement and heavy foot traffic. 

Where high movement expansion joints are required in construction, the Gorilla MS Sealant and the Soudaseal FR provide the movement and durability characteristics required under the building code. For these demanding applications, Soudal’s polyurethane and SMX hybrid polymer sealants deliver long-lasting flexibility and adhesion. Soudaseal 240FC is a high-performance joint sealant with excellent adhesion to concrete and metal, making it ideal for industrial flooring and public infrastructure projects. When higher movement capability is required, Soudaseal 270HS offers superior elasticity and high mechanical strength, ensuring joints remain sealed and durable even under extreme conditions. 

For more general-purpose sealing, Gorilla MS provides a flexible, weather-resistant bond suitable for both indoor and outdoor joints, while Soudal 940FC is a professional-grade polyurethane sealant formulated for high-load areas where chemical and fuel resistance is critical, such as car parks, fuel stations, and warehouses. 

Each formulation is engineered to handle expansion, contraction, and exposure to fuels or cleaning agents, ensuring strong, reliable joint performance over time.
