An effective method for repair of coastal piles is to use a pile jacket system and a reliable underwater grout. These repairs can take place above or below the waterline. The method involves encasing a deteriorating pile with a jacket or formwork and filling the voids with an underwater grout.
For almost twenty years, we’ve offered a wide range of marine grouts and repair solutions for major civil infrastructure projects. The grouts listed below contain engineered cements, additives and selected aggregates to produce a customised, high-performance marine grout for all pile jacket grouting applications.

Products from the BluCem range often chosen by contractors for tidal repairs as they have exceptionally high early strength development. This allows the grout to remain fluid during placement at low tide and ensures a solid, high-strength grout as the tide returns.
As a marine-grade shotcrete with high chloride and sulphate resistance, BluCem HB55 is based on CSA cement technology for use in concrete works requiring quick, reliable turnarounds. With a low carbon footprint, it also reduces waste on defective goods and has a long product lifespan, meaning you’ll get value as well as a speedy return to business as usual.

Shotcrete is widely regarded as the preferred repair method for large, overhead and vertical structural repairs in marine environments. The blend includes a mixture of cement, sand and additives which are combined in a mixer and shot through the delivery hose by compressed air. Shotcrete eliminates the need to erect formwork, saving both time and labour costs.
BluCem HB55, our dry spray shotcrete, consists of specifically graded aggregates to create maximum interlocking during spraying to build depth of several hundred millimetres in one pass. Its low electrical resistivity also makes it suitable for repairs involving cathodic protection.
