Soil Stabilization

1- SDCLD-1
LIGHT DUTY SAND & DUST CONTROL

SDCLD-1 provides an economical sand stabilization solutions to protect
railways and roads and other areas not expected to experience any form
of traffic damage using the tried and tested polymer technology developed
in the Middle East for the moving sand problems experienced on the regions
roads and with the regions rail connections.
The same technology can also be used on wide area dust suppression at
industrial plants or areas not expected to have to carry traffic and is a significant
tool in the fight to maintain plants and operating facilities like warehouses and
offices free from ingress of blowing dust and sand.

SDCLD-1
• SDCLD-1, is surface sprayed in a water diluted form to create a hard crust to reduce sand migration and erosion of the berm/flat areas.
• The crust achieves the required strength within a few days to withstand most of the regions weather changes.
• The application forms a crust (matrix) with the sand surface layer – typically 1 – 5 cm depending on the granulometry of the sand.
• The surface will be water resistance against occasional rain once SDCLD-1 cured.
Benefit
• Economical sand/dust stabilisation technology for lighter duty applications.

2- HDSDC-2
HEAVY DUTY SAND & DUST CONTROL

HDSDC-2 heavy duty sand stabilisation solutions using polymer technology to protect roads and railways from migrating sand and the safety hazards they cause.
HDSDC-2 technology summary
• Design a berm on the side of the road / railway to be protected. (based on weather conditions, soil type, distance from road, berm height and berm slope can be calculated)
• Stabilise the berm using HDSDC-2, to create a hard and durable crust suitable for the local weather conditions and traffic profile.
• The crust “cures” to achieve the desired strength suitable for the local weather and the foot traffic.
• The technology protects the road from sand accumulation on the protected road / railway / industrial site.
• The surface will be weather resistant once HDSDC-2 cured.
Benefit
Safety: reduced accidents and improved access and transit times as there is no
rapid sand accumulation. Maintenance (sand removing) will happen away from
the road / railway and not on the road / railway thus keeping traffic free-flowing
and safe.
Cost saving: Sand removing maintenance will reduce from (in some cases) every
week or two weeks to every 6 months or more depending on the weather
conditions, the removal costs are lower and require fewer crews and equipment
so for the same budget larger portions of the country’s infrastructure
(road and rail) can be kept safe and operational.

3- PRS-5000
Polymer road construction solutions

PRS-5000 Polymer road construction solutions use
PRS-5000 polymer technology to provide service roads,
car park areas, airstrips or helicopter pads.
PRS-5000 is the chosen polymer replacement for asphalt
roads and sub base improvement to provide better load bearing
capacity in poor soil conditions.
PRS-5000 Road construction technology
The contractor is now able to provide quick and easy solutions to the regions challenges,
especially on poor sand and low CBR (California Bearing Ratio) sub bases including:
• Construction of all-weather roads from locally available soil (local soil assessment required)
with improvement in engineering properties of the polymer stabilized road.
• Simple easy to implement, no special equipment required, regular road compaction
equipment will be used to construct the road.
• Avoid/minimize the cost of importing material.
• Improved CBR ratings especially in areas with high fines content, local testing of optimum
moisture content enables TF-5000 technology to be tailored to the specific project.
• Reduction in downtime compared to traditional asphalt and cementitious solutions with
comparable life expectancy (with planned maintenance)
Benefit
• The PRS-5000 treated soil showed an 80% CBR improvement. When tested for wet
UCS values, the untreated soil generally, after soaking, had zero strength and became
completely dissolved in the water bath whereas the PRS-5000 treated soil resisted the
degradation.
• The surface will be water resistant once PRS-5000 is cured.
• The constructed polymer road will withstand heavy traffic use.
Easy to maintain – cost effective over whole life
Life cycle cost considering initial and maintenance costs (consider minimum; minor
maintenance treatments every year)
The recommended maintenance schedule is dependent on the application and project;
however, a typical maintenance schedule is as follows:
• 30 days after application: Technical Inspection (application assessment)
• 180 days after application: Maintenance Inspection (Seal Coat application if required)
• 360 days after application: Annual Maintenance Inspection (Seal Coat Test &
Recommendations) **
• 540 days after application: Maintenance Inspection (Seal Coat application if required)
• 720 days after application: Annual Maintenance Inspection (Seal Coat Test &
Recommendations)
