ROMEX® DRAIN
Highly Permeable Jointing
Ideal for Green Infrastructure projects
This two-component jointing product is combined with water in a gravity mixer to create a slurry-like mortar that easily seeps into your paver joints using a squeegee on pre-wet pavers. Wait 15 minutes, then just brush off the excess product to reveal your completed highly permeable surface. This is great for working with strict permeability regulations on green infrastructure projects and is compatible with joint widths greater than 1/4″ | 5mm.
WEATHER WARNING – Only install at surface temperatures between 0°C – 30°C | 32°F – 86°F. Lower temperatures result in slower hardening while higher temperatures cure faster. 20 – 30 minute working time.
- For light traffic loads up to 3.5 T (Up to 40T with RSG)
- Self-compacting
- Pressure washer safe
- Highly water-permeable
- Frost and de-icing salt resistant

Keep in Mind: Ensure the foundation meets load expectations and adheres to industry standards for permeable pavement construction. Future loads must not cause surface to settle or loosen stones. For optimal results, consider
using ROMEX® Trass-Bed products along with the ROMEX® SYSTEM-GUARANTEE (RSG). Utilize ROMEX® application tools available at your dealer for the best application experience.
Preparation: For paver thickness less than 30 mm, employ bonded laying methods (Trass) For unbonded methods,
clean the jointing surface thoroughly before starting work and tape off adjacent surfaces. fill joints completely with
ROMEX® – DRAIN.
Pre-wetting: Pre-wet the surface adequately, especially porous surfaces and areas with higher temperatures.
Mixing: Pour 25 kg | 55 Ibs of filler sand into the mixing tub and begin the mixing process. Gradually add the separately packaged 1.8 kg | 4.0 Ibs resin/hardener component while mixing. After 3 minutes of mixing, add 2 litres | 0.53 gal of water by filling the resin/hardener bottles with 1 litre | 0.26 gal of water, shaking vigorously, and adding the contents to the mixture. Continue mixing for at least 3 more minutes using a rotary-drum mixer / drill mixer with helical mixing paddle.
Application: Apply the mixed pavement jointing mortar onto the prewetted surface and work it carefully into the joints using a squeegee/rubber slider. Do not pour entire contents in one spot, instead, pour the mortar at several spots within the jointing area to optimize fluidity. If not used immediately, remix the remaining mortar briefly before continuing application. Regularly clean tools and work shoes with water spray to prevent impurities and footprints on the stone surface.
Final cleaning: After 10-15 minutes and once no white streaks are noticeable from brooming, carefully sweep off excess mortar from the stone surface with a large, coarse broom. Then, use a soft, hair broom for a final cleaning until all residual mortar is removed. Sweep diagonally to the joint and avoid reusing swept-off material.
Subsequent treatment: Protect the freshly jointed surface from rain for the next 12-24 hours. Ensure the rain protection layer allows sufficient air circulation and is not laid directly onto the paved surface.
Important Note: During the initial period, a thin film of epoxy resin may remain on the stone surface, enhancing color and protecting it from dirt. This film is temporary and will weather over time. To confirm, test a sample surface before completing the entire jointing process. A resin film does not indicate a fault in the application, and the surface quality remains uncompromised.
