High density DenseCRETE® heavyweight concrete can be poured, pumped, or conveyed, and is as versatile as conventional density concrete in both application and usability.

NSS high density DenseCRETE® heavyweight concrete mixes and designs are specifically tailored to the unique requirements for each individual project.You choose the solution that fits your space and your budget.

Like regular concrete, our high density DenseCRETE® heavyweight concrete can be poured in place, pre-placed, made into ShieldBLOCK® transportable blocks and slabs or grouted (ShieldGROUT®) around existing framework.

For example, in radiation vaults, densities of up to 325 pcf (5.21 g/cc) will reduce the required shield wall thickness and/or increase the usable interior room space by up to 55% when compared to conventional concrete at 147 pcf.

Using NSS high density DenseCRETE® heavyweight concrete eliminates the need for, and the high costs associated with, composite shields which can consist of combinations of lead, steel, concrete and polyethylene. DenseCRETE® alone is capable of attenuating the full range of ionizing high-energy radiation due to its extreme weight as well as its hydrogen and optional boron content. DenseCRETE® attenuates gamma, x-ray, proton, and neutron radiation all in a compact and relatively inexpensive footprint.

NSS never uses any lead in our high density heavyweight shielding products. Our products are all completely non-toxic and environmentally safe.

NSS's site-formed systems can be installed anywhere in the world using a local conventional mixing plant or our portable jobsite batching system.  

Should your project require radiation shielding blocks (ShieldBLOCK®), NSS sister company, Shielding Construction Solutions, Inc. (SCS), is equipped to install them.
