Product Information Manual
PURE-CRETE is a complex not-bacterial concentrated multi-enzymatic formulation that alters the properties of earth materials, providing one of the most cost-effective methods to stabilize roads and seal ponds and landfills.
WHAT IS PURE-CRETE?
PURE-CRETE is one of the worlds finest products for road stabilization and pond and/or landfill sealing. PURE-CRETE, a concentrated enzyme formulation, alters the properties of earth material to produce superior road base stabilization compared to all other road treatment materials now in use. Developed and proven through many years of field testing, PURE-CRETE provides additional advantages to road builders, communities and the environment by being non-toxic, non-corrosive and totally biodegradable.
When mixed with water and applied prior to compaction, PURE-CRETE acts upon organic fines contained in the soil through a catalytic bonding process, producing a strong cementation action. Unlike inorganic or petroleum based products which temporarily hold soil materials together, PURE-CRETE causes the soil to bond during compaction into a dense permanent base which resists water penetration, weathering and wear. This process takes place in 72 hours under normal summer conditions.
In addition to creating a new and better way of building and maintaining roads, PURE-CRETE is being used successfully in the construction of lake beds, mine leach pads, ponds and land fill liners, wherever there is a need to increase the load-bearing capacity of the soil and to reduce the plasticity and permeability.
PURE-CRETE lowers the surface tension of water which promotes fast and thorough penetration and dispersal of moisture. This action causes hydrated clay particles to be pressed into and to fill the voids throughout the soil, thus forming a tight, dense permanent stratum. The increased lubricity of soil particles allows the designated soil density to be reached with less compaction effort.
PURE-CRETE reduces, by as much as 25%, the amount of water required to reach the optimum moisture level of the soil since it promotes rapid saturation and inhibits surface evaporation. The PURE-CRETE cementation action increases the soil bearing characteristics by promoting a closer binding of soil particles. This reduces the tendency of the soil to expand after compaction and results in a strong, stable earth layer, by achieving greater bonding density, soil materials resist migration of water. A properly treated PURE-CRETE base becomes almost impervious to water penetration and much more resistant to frost heaving.
Road builders can now construct a new road base using existing soil materials without trucking in additional aggregate (if sufficient fines are present). Mixing PURE-CRETE with the top 5 or 6 inches of soil will produce a road base that has more strength and less permeability that can be attained with any other treatment. If imported material is needed, less expensive, dirty aggregate is a requirement. The dirty fines are needed to bond the material together. Dirty here means 15% to 20% cohesive fines passing a 200 mesh screen. The best part is that only 15 gallons of PURE-CRETE is needed to treat one mile of a 25-foot wide roadway (6 inches deep).

to water penetration...? Here are two
PURE-CRETE can be applied over a wide weather and locale range. From near freezing to hot summer days, from a rain forest to a desert, from lake bottom to an earthen dam, PURE-CRETE will provide superior results. New or existing roads treated with PURE-CRETE to the recommended depth will retain a tough, rupture-resistant surface that requires minimal maintenance, often requiring no additional "dressing" for a number of years.
PURE-CRETE is sold in liquid concentrate form. This eliminates the bulk storage, pre-mixing and handling of large amounts of materials. It will not corrode equipment. PURE-CRETE is non-toxic. It requires no special handing equipment and no special containment procedures as required with toxic and/or corrosive agents. It does not irritate skin tissue and causes no rashes or burns. PURE-CRETE contains no combustible materials, in non-explosive and can be used near open flames. It is non-gaseous and can be stored in poorly ventilated areas. It will not harm humans, animals, fish or vegetation under normal use and is totally biodegradable.
PURE-CRETE is easy to apply and requires no special equipment nor application procedures. It can be used with reclaiming machines or applied with regular road building machines. PURE-CRETE should be used with soils that contain approximately 20% cohesive fines. It is mixed with water used for compaction during normal road building techniques.
SEALING LAKES, PONDS OR LANDFILLS
For new construction, add PURE-CRETE to water as described above. The soil should ideally have approximately 25% to 30% cohesive, colloidal fines (200 mesh). Blade or disc the soil to blend in the PURE-CRETE and water, then grade and shape. Next compact the soil at optimum moisture using a compactor, tractor or truck. Generally the top 10 to 12 inches is treated for most liners. When an existing pond or lake is filled with and less than 8 feet in depth, use one gallon of PURE-CRETE for every 6,000 square feet of surface area (8 gallons per surface acre). Pour PURE-CRETE into the water from the windward side and around the perimeter, or across the surface if a boat or pump can be used. Stir up the silt from the bottom of the pond any way possible (dragging chains sometimes works). Fines placed into suspension together with the PURE-CRETE will then migrate to the seepage areas. Do not add water for 3 days. PURE-CRETE disperses clay and colloidal materials into the voids between each grain of soil and causes a catalytic bonding process, creating a strong, tightly compacted stratum that resists water penetration.
Success with this method will depend on the soil composition of your pond. If loss by seepage does not stop within 10 to 14 days, you can let the pond dry and re-retreat using new pond construction methods described above. PURE-CRETE will not harm fish if used properly. It is most effective in sealing the soils in ponds when at lease 25% of the material contains fines that will pass a 200 mesh screen, and the fines are primarily cohesive clays.
