Concrete Waterproofing
Waterproofing new and existing concrete surfaces often starts with a good project design featuring a multi-defence strategy. The most common is the barrier protection strategy, which often starts with correction to the substrate. Sika offers a variety of products suited to most concrete waterproofing situations.
Typically, positive and negative waterproofing strategies can be implemented using the following products:
Liquid Applied Waterproofing Membranes
Positive barrier protection can be achieved using the range of Sika and Concrete Protection manufactured products, all of which meet all applicable Australian Standards.
Cementitious Waterproofing – Sikalastic 1K
Cementitious membranes have the advantage of working well on both the positive and negative side. Sikalastic 1K is a flexible, fibre-reinforced mortar that only requires water for mixing.
Contec C1 Waterproofing Concrete Additive and Repair Compound
Contec C1 is a crystallising, self-sealing waterproofing system that turns porous concrete into a permanent, water-resistant barrier.
