The SikaSwell S-2 is a one-component expanding polyurethane sealant developed by Sika specifically designed for waterproof sealing of construction joints and penetrations in concrete. Its uniqueness is that it expands upon contact with water, thus ensuring active and durable waterproofing.
Easy and quick to implement, the SikaSwell S-2 is a high-performance solution compared to other sealing systems. Its optimised expansion rate ensures effective sealing without the risk of damaging fresh concrete, even under demanding application conditions. Permanently water-resistant, including during alternating wet/dry cycles, it offers good adhesion on many substrates and maintains its performance over time. Its versatility makes it a preferred product for many structural sealing applications.
The SikaSwell® S-2 is ideal for sealing construction joints, waterproofing pipe penetrations and steel elements through walls and slabs, treating duct and cable passages, and sealing around all types of penetrations and reservations in concrete.
