Portstone Block Cap by National Masonry. Modernstone walls can be built up to 1050mm high with the cap or higher with engineered reinforcement. Modernstone's defining feature is a longer and lower profile than most large retaining wall blocks. This gives it an elegant profile which looks less like a besser block and more like artisan crafted sandstone or bluestone. Sweeping curves, straight walls, 90 degree corners and the finishing touch of a large capping unit are easily installed and the results are stunning.
