PROTECTING ROADS FROM MOISTURE DAMAGE Water on pavements is the primary cause of premature damage. It can shorten the service life, reduce the load transfer mechanism, and require costly repairs. Many engineers consider adequate drainage of both the surface and the subgrade to be the most important element in ensuring the long-term performance of a pavement and minimizing the damaging effects of water.

Our RD SolDrainTM is the engineered solution to

problems associated with drainage in road-ways,

parking lots, paved walkways, airports, railway

facilities, embankments, and dike drainage.

By providing excellent drainage, RD SolDrainTM

greatly extends their service life and reduces

maintenance costs. RD SolDrainTM is easy to install

and readily available.

HORIZONTAL SUBSURFACEDRAINAGE SYSTEMRD SolDrainTM is a high strength HDPE geocomposite comprised of a triplanar geonet core, heat bonded on both sides with geotextile filters that prevent clogging and provide unobstructed linear flow channels.

Compared to natural stone drainage layers,

RD SolDrainTM provides a compressive strength of

> 50,000 psf and a permeability of ten times that of

drainage stones and forty times that of an untreated

permeable base.

In addition, the void maintaining triplanar core

prevents the top and bottom geotextiles from

touching, even under extreme loads.

SATURATION AND IMPACT TO SERVICE LIFE

S = SEVERITY FACTOR

S=5

S=10

S=20

Severity factor

measures the relative

damage between wet

and dry periods.

For a pavement section with a moderate severity factor (10), the pavement service life could be reduced by half if the pavement is approaching saturation just 10% of time.

RD SOLDRAINTM JD

RD SolDrainTM JD is placed directly beneath the concrete pavement at only the expansion joint locations.

Reducing the area of coverage lowers the overall cost by focusing on the most critical entry point of

water into the pavement system. In field testing, RD SolDrainTM JD has proven to be an effective alternative

to drainable bases, even collecting moisture from sealed expansion joints.

EXPANSION JOINT DRAINAGE STRIP FOR RIGID PAVEMENTS

BENEFITS

RD SolDrainTM void-maintaining triplanar core.

Open flow channels to direct water out past the edge of the pavement.

Rapid evacuation of water that virtually eliminates any pore pressure.

More effective performance than geotextiles alone: >75 times under static condition and >150 times under traffic.
