Road Seal is a proprietary brand of seal surfacing. When applied on existing surfaces it provides a waterproof, skid resistant and textured surface free from loose agregate and prevents deteriortation.

 Road Seal Africa Ltd is an established buisness based in Morocco offering 10 years of experience with a leading environmentally safe product with improvement in permeability and erosion control.

 Road Seal can add as much as 3000 percent more strength to the exposed surface of an unpaved road and eliminate dust polution.

Using routine construction equipment, Road Seal can be made quickly and efficiently at the project site. It’s cost is also substantially lower than traditional asphalt surfacing. It also provides an excellent alternative to asphalt resurfacing.

 Road Seal can act as a superior stabilizer binding the old base together in contrast with traditional asphalt resurfacing which causes deposition of asphalt emmission damaging the environment.



The first stage involves the preparation of the soil. The soil is loosed as much as possible prior to the first application with Road Seal. This helps ensure a deeper and more thorough penetration into the soil base.

This can be achieved by using a stone crusher or by using a scarifier on a grader.



The second stage involves the even distribution of Road Seal into the soil.


The third stage involves the grading of the of the product to allow for a level surface.


The fourth stage is the secondary application of Road Seal which is again evenly distributed.



With a specialized machine equipped with a powerful milling and mixing rotor, the Road Seal will be mixed into existing soil at a working depth of up to 50 cm.

 And so converts the Road Seal into a fully pre-compacted construction material of high bearing capacity in an in-situ process.



On the first and second application of the Road Seal a compaction effort is taken to tighten the Road Seal with the soil. After the second application a final compaction operation is taken to ensure that the specification of the particular soil being treated are met.



The third application acts as a reinforcement over the treated base. During this ultimate spraying, the product should be evenly distributed over the area of coverage and allowed to completely soak into it prior to allowing traffic.
