Waterproofing of excellence
Sika now presents its latest innovation in structural waterproofing:
SikaProof® A – a highly flexible, pre-applied, fully bonded membrane system for basement waterproofing. This innovative system is based on well-known existing technologies from Sika’s construction and automotive business and so combines the expertise of both the sealant and adhesive technology and the waterproofing market.
In contrast to existing polymeric Sika membrane solutions, the special SikaProof® A system build-up – consisting of an embossed highly flexible polyolefin membrane, a unique grid pattern sealant and a specially designed fleece – creates a full surface mechanical bond with the hardened concrete. Due to this bonding effect in combination with the grid sealant, there is no water underflow between the concrete structure and the membrane in the case of any damage to the latter.
Another major difference compared to traditional sheet membranes is the way that the individual sheets of SikaProof® A are connected to each other. Instead of relying on a time-consuming hot-air welding procedure, the membrane sheets are joined using either the self-adhesive strip on the membrane or by fastening them together with specially designed self-adhesive tapes. This quick and easy system for adhering sheets is also very cost-effective as it eliminates the need for special tools and saves costs thanks to faster installation. Plus, the absence of open flames spells increased safety in application on-site. Furthermore, the tried-and-tested long-lasting polyolefin membrane provides an additional benefit for owners in the form of higher durability. This is Sika’s contribution for a more sustainable world.
SikaProof® A is a high quality, easy to apply and totally cost optimized waterproofing solution for new construction and renovation works. The system can generally be used for damp-proofing, concrete protection and waterproofing of all types of reinforced concrete basements and other below ground structures. Typical projects include residential and commercial buildings (e.g. housing developments, retail complexes, public buildings), stadiums and leisure facilities, as well as factories, warehouses and other industrial constructions.
