Sika SikaProof® A+ 08

Water pressure-tight and crack-bridging fresh concrete composite system with innovative hybrid bond and back-up protection
SikaProof® A+ 08 is a pre-installable fresh concrete bonding system (FBVS) for concrete structures
The basis is a 0.8 mm thick plastic waterproofing membrane made of highly flexible polyolefins (FPO)
The membrane is equipped with a special hybrid composite layer based on cement-modified polymers and has a total thickness of 1.35 mm
The system creates a permanent, full-surface bond with the hardening fresh concrete and reliably prevents any backtracking in the event of unintentional damage
Innovative hybrid bond through adhesion, bonding and needling with the hardening fresh concrete
No trailing between the plastic sheeting and the concrete component
Pre-installable system - membrane is laid on a suitable substrate before concreting
Easy and flexible to install - seams can be joined by gluing or thermal joining
High impermeability - approved up to 20 m water column
High strength and elongation
Highly flexible and crack-bridging
High flexibility at low temperatures
High resistance to mechanical stress
Resistant to ageing
Resistant to all natural aggressive substances found in groundwater and soil
Resistant to roots and microorganisms
UV-stable for the time of installation (3 months)
Can be laid on damp substrates
