Injectable Waterstop

Sika is proud to carry the world’s number one injection hose system. FUKO is a specially designed and patented solid core PVC Injection Hose System which is installed in concrete joints to waterproof and seal any cracks or voids in the joint area. The FUKO System seals joints watertight and offers a complete maintenance program if leakage appears in the future. When appropriate Sika injection resins are selected, the FUKO System can be used for multiple re-injections – a significant advantage over any other hose system available.
