A waterproofing material for reinforcement of sand levees, soil and construction earthworks


Waterproofing flood protection sandbags


Flood protection sandbags are usually filled with sand. These bags soak through during the flood after a certain period so the emergency levee needs constant rebuilding and reinforcement. Also, the subsequent treatment of used sandbags raises concerns because the sand gets contaminated during the flood and is considered hazardous waste, therefore its disposal needs to be taken care of after remediation.


Sand mixed with HYDRO RESIST (added in a 3-5% ratio) becomes waterproof and does not soak through, resulting in stronger and more reliable sandbag levees.


If this method is used, the sand does not get contaminated, and sandbags only require outer cleaning (e.g. by a pressure steam washer) once the flood has receded; the sand remains clean and is reusable after it has dried.



Building watertight layers for soil and earthwork reinforcement


Another major field of application for waterproofed sand is to build watertight soil layers. These are used primarily for soil reinforcement in waste disposal facilities, artificial lakes, and sometimes for shutting down soil zones (e.g. for combined confinement and isolation of contaminated areas).


An additional important utility is road and public utility network (sewer and water pipelines) construction.


The application of HYDRO RESIST largely depends on the quality of the sand used, so just as in construction, the sand needs to be evaluated in each case and the mix ratio determined for the given material.


It is a brand new technology.



There are ongoing and planned R&D projects with companies involved in road and public utility network construction where HYDRO RESIST is applied and built into earthworks according to the specific requirements.
