SikaProof® A+ Technology

The technology was developed from Sika’s elastic sealant and adhesive bonding expertise. The innovation provides a durable and reliable bond between the membrane system and the structural concrete. This property provides high safety and long-term watertight solution.

Any water ingress is limited to the damaged area and the water is prevented from lateral migration between the membrane and the concrete structure. That makes the repair by local injection of damaged areas simple and effective, due to its locally limited area.

If non-bonded systems are damaged, water spreads uncontrollably between the membrane and the concrete. Water can easily enter every weak point of the structure, such as joints and cracks.

The fully bonded technology is the back-up for the SikaProof® A+
system in the event of a damage to the membrane, which is the primary
waterproofing layer.
