At 4Site we always use the most appropriate products for the project in hand. The choice of product being determined by its properties and strengths and how it delivers in comparison to other alternatives for any particular project. To this end, we have specified SikaProof®-A on many projects.
Sika is a unique waterproofing system which consists of an embossed, highly flexible polyolefin membrane, with sealant and a specially designed non-woven fleece.
When the fleece is completely adhered to the fresh concrete it forms a durable mechanical bond. Furthermore, because the sealant is embedded within a unique grid system it prevents any lateral water underflow and migration between the product membrane and the structural concrete.
