Nga Son Hotel Construction Project in Thanh Hoa province is a typical hotel project designed with long-span floors. VRO’s system with foam voids, therefore, is the best choice to construct such flat-plate floors. Moreover, VRO’s slab technology has superior advantages over other voided systems on the market. Let’s check out as following:
Location: Thanh Hoa Province
– Optimizing architectural space
– Reducing the floor-to-floor heights because flat-plate floors don’t have loading beam, thus saving materials and energy
– Increase the number of floors at the same designed height of the building, then increase the operation efficiency
– Longer floor span (can reach 20m)
– Simple formwork, fast construction and clean jobsite
– Reduce the volume of works at jobsite
– Better bearing capacity
– Using eco-friendly unburnt materials
– Reduce the finishing volume
– No need to install false ceiling but still has very good sound and heat insulation
– Production following a standard process with strict quality control
– The input materials have clear origins with due C/O
– Optimal architectural space

– Fast construction, clean site, directly painting without waiting time
– Lightweight, about 35-50% less than the weight of conventional brick wall
– Sound & heat insulation, waterproofing
– Durability, high hardness because the brick is made from high grade concrete (grade > #200) with reinforcement, so it is stiff enough to hang heavy stuff.
– The finished walls have different thickness options: 100-125-150-175-200-250mm.
– The construction cost is equivalent to that of conventional brick wall 110cm and is about 10 to 15% more economical than the conventional brick wall 220cm.
– The wall is built with mortar added with plastizing admixture to form a whole block, so there is no splitting and node cracking as seen in other kinds of block wall.
– The construction process is almost similar to building large burnt bricks, so ordinary workers can also build immediately
– Production of bricks is arranged at the site to reduce transportation costs, greatly reducing product costs. Because this is a kind of unburnt brick so it’s very environmentally friendly.
– Brick can be used as a load-bearing wall to replace wall column when building a house up to 3-4 floors. In that case, steel is added the hollow bricks to create a pillar or bracing of the floor.
– It is possible to build large walls up to 10m high for projects such as factories and halls
