Dirt Stabilizer for BMX and Mountain Bike Dirt Jumps
DirtGlue JumpTM is a powerful, high-tech water-based adhesive specifically engineered to bond soil particles together for BMX, Mountain Biking, and other recreational dirt trails. Offering best in class performance for building big air jumps, jump parks, rollers, berms, and general dirt trail stabilization, DirtGlue Jump (DGJ) is a “purpose built” liquid concentrate that penetrates the surface, binding with the soil to form a tough long-lasting solid dirt feature. It is UV-stabilized and highly durable to withstand frequent bike park use over several years or
longer.
As a non-hazardous product, DirtGlue® acrylic polymer contains no harmful chemicals, and will not adversely affect people, animals or aquatic life. DirtGlue® polymers have received numerous regulatory approvals including US EPA non-hazardous classification, DOT HAZ rating of 0, European Union REACH certification, California Water Board approval, US Army Corp of Engineers (USACE) for use on SuperFund sites, FEMA, ATEC (US Military health and
environmental standards), and many others.
DGJ is shipped in liquid concentrate form, then diluted at the job site with water. For superior strength and extreme lifespan, the product may be mechanically mixed in the soil/aggregate and compacted. This application would use a 1:1 dilution ratio. The mix in and compact application rate is 1 gallon per 36 square feet of jump feature, per inch of thickness. GES recommends building jumps with 2”-3” of treated soil over compacted base material, so
each gallon would treat 12-18 SF.
For best results with DirtGlueJump, use graduated soil size distribution with no soil chunk or rock that is bigger than 2” and that include 20% - 25% fines to avoid air pockets. The material should be able to compacted. Then loosen the soil or dirt in the area to be treated and apply the DGJ dilution using a watering can, gravity water bar, or pump sprayer (remove nozzle, not to be misted). Larger projects can use a diaphragm pump such as AODD; avoid using impeller style pumps with polymers.
After applying the blended liquid to the aggregate/soil, mechanically mix in thoroughly and evenly, using a hoe, shovel, or rake to blend in as evenly as possible. Depending upon type of equipment used this could take two or possibly three applications to get all the liquid into the soil/aggregate at 2 - 3 inches deep. Then compact the feature to desired shape.
Curing time depends on temperature and humidity; the warmer and dryer the climate the faster DGJ cures. Do not apply when overnight lows are <52°F or when rain is forecast within 24 hours. Make sure feature is appropriately cured before use, it will feel as hard as a rock.
DirtGlue/Jump may also be surface spray applied. This type of application will need touch-ups at crash sites, and periodic reapplication die to damage to the thin crust that this application type creates. . Dilution ratios are adjusted for soil type and application rate of the concentrated polymer and range from as little as 3:1 up to 6:1 (water: polymer).
As with other GES DirtGlue® liquid polymer soil binders, it must be protected from freeze while in concentrate form. It can be stored for up to a year in a covered, sealed, store in cool dry location <70°F.
GES West is available to help with project materials estimations and budgeting. 5 gallon jugs of DGJ can be ordered online at (insert link) and shipped UPS. Larger projects can be supplied with 55 gallon drums and/or 275 gallon IBC totes via freight carriers.
