Construction & Civil Projects
Heavy Civil construction involves a lot of activities during the life of a project. Most of them are designed to improve our surroundings to accommodate growth and expansion. During these projects many of the activities we perform, disrupt the native soils which, if not controlled can and will leave the site, either in the wind, or in the run-off during rainstorms. Our products are intended to mitigate these either during the construction process through soil stabilization. .. and then reclaim the disturbed area after construction.
Our DirtGlue Polymer is an acrylic polymer that when applied to soils, whether they are flat or on a hillside, form a crust over the surface to retain soils during construction. Our philosophy is different: Rather than (or in addition to) building an erosion control fence at the bottom of your slope to catch soils in the run-off, we have proven that our DG polymer will keep the soils from leaving the site and thus cannot enter the waterways surrounding the construction site. This polymer mixes with water in your water trucks and can be applied via spray bar or spray hose to accomplish this coating.
After construction: Once the site is reaching the reclamation phase, our system involves spraying down good compost, our CompuMulch or Humalfa is comprised of Compost and Green Vegetable fiber that will be mixed with your specified seed mixture. This can go down dry blown or hydro-seeded. When this is covered with our DG Polymer above, the polymer crust hold the compost in place while the seed germinates through the crust. The crust allows water and growth to penetrate but does not allow the compost to leave the site and will remain in place until the seed has taken root, often up to a year.
What have we been doing?? Think about this... during construction we build the highway embankments and then to keep the soils in place, we run up and down the hillsides with a D9 Dozer... compacting the soil so it wont run off, (This is great for growing seed in), we then come back and add our top soil onto the embankment with another tractor or loader.. good compaction here.. and then with a tractor we run the seeder over this to spread our seed. This is then covered with blown on straw ..which we then crimp into place ( with another tractor) .. then come back and spray a tacifier like Guar-gum over the straw. Sounds plausible, and acceptable to most DOT's and Municipalities. Then we sit back for three weeks and after the first rain storm, the Guar-gum tacifier (which absorbs water) has liquified or washed off, we watch the straw blow away, and half of our seed along with it. This is when the proof of concept appears in a germination rate of less then 50%. (some DOT's have resorted to drill seeding.. hmm good idea, but then, this is another pass of the tractors, further compacting the top soil or compost and truly making germination almost impossible)
Oh Don't worry, that's why they developed Hydro seeding with mulch and that pretty green dye. Right? Of course...hydro-seeding with that wonderful shredded wood mulch is great, and its cheap since the wood is almost free from Forest Service. Here lies the issue....... wood fiber absorbs moisture, and then it must decompose into the soil right? Well in order for this so called decomposition to take place, the very nutrients that your seed needs to grow, nitrogen and the moisture are consumed above the seed and never reach the embedded seed. Thus the very products you are putting over your seed.... are competing with your seed for essential nutrients ... thus we get 50% germination "or less". We have shown that seeds germinating in a good compost do much better... if you can only keep the compost in place. This is where our DirtGlue Polymer comes into play. Our Polymer can be applied right out of a Hydro-seeder, or from a construction water truck, and is diluted in 8 to 12 gallons of water per gallon of Polymer. It dries clear, and allows seed to germinate through it.
Don't get this wrong: There is nothing wrong with hydro-seeding applications... only the material we are putting down. The results a obvious.. and the germination rates are atrocious. At the same time, you , our customer, is being asked to guarantee your applications, often for two years, knowing full well that the only method of seeding they will accept... gives poor results.
