In a search for engineering compliance, our supplier has produced a superior engineered block and placement method that complies with engineering standards and enables them to be placed in remediated mine areas, harsh marine environments and waterways. Across the globe, hard structures have been used for long term protection against erosion. Xstream & XstreamPlus Blocks range in size from 30 to 40 cm height. While the Xbloc can be as tall as 3m. The Xbloc system is based on randomly placed, interlocking concrete armour units. It has been applied successfully in breakwaters and shore protection projects on 6 continents in block sizes ranging between 1.8 and 40 ton. The Xbloc can also be complimented with the XblocPlus.

We can work with your preferred contractor and supply them the blocks. If it is the first time your contractor has used our system, we will work alongside them to ensure that the design and installation are done correctly.
Please note: If it is your first time using our system, as a condition of sale, we will work alongside you during the design phase. We will be able to pass on what we have learnt and things to look out for, this will save you time and money in the end.
We will also have one of our experienced installation team to oversee and help when your first project is due for installation. Depending on the size of the project, this could be a half day to two-day exercise and come at a small cost to cover expenses.

We will project manage and facilitate the entire process, whilst keeping in close communication with you.
