Media depth
Define growing depth, profile layers, plant type and available root volume.
Engineered system review
Rooftop & Green Roof
Rooftop media is part of a complete engineered assembly. Product selection begins only after planting, depth, loading, drainage, specification and placement are understood.
Review required
Begin with the whole rooftop system.
A rooftop project does not automatically select one Lava family or one catalog product. Verify current project requirements before selecting the media.
Loading requirements
Use current project and engineering criteria; do not publish assumed saturated weights.
Drainage system
Review the complete assembly, outlet and water-management design.
Planting & irrigation
Connect the plant community and establishment plan to the media behavior.
From specification to placement
Documentation, sample, volume and access.
Rooftop logistics can be as important as the material itself.
Specification
Send the governing media and assembly requirements, acceptable substitutions and testing needs.
Learn more →Current documentation
Request only verified current product or project information.
Learn more →Sample
Define the sample purpose, approval path and deadline.
Learn more →Bulk logistics
Plan volume, truck staging, crane or placement access, phasing and site constraints.
Learn more →Planting review
Identify extensive, intensive or other planting design without forcing all rooftops into one path.
Learn more →Project contact
Keep specification, production, documents and logistics connected through review.
Learn more →No simplified weight comparison without current data. Saturated loading, formulation and assembly criteria require verified project information.

Rooftop & Green Roof FAQs
Use the project details—not the broad label alone—to choose the next step.
Which Specialty Soils product is best for every green roof?
There is no automatic single answer. Planting, depth, saturated loading, drainage, specification, volume and placement must be reviewed.
Can you publish a saturated weight?
Only current verified project or formulation data should be used. Do not rely on an unsupported generic value.
Can pumice be part of rooftop media?
It may be one component, but pumice alone is not complete media and does not replace engineered-system review.
What should the project team send?
Send plans, specification, planting, depths, loading criteria, drainage assembly, quantity, schedule, access and documentation requirements.
Request an engineered-system review.
Send the specification, planting, depth, loading, drainage, volume, schedule and placement constraints.
