ABOUT THIS SYSTEM
No-fines gravity retaining wall system.
Urbanscapes supplies and installs no-fines gravity retaining walls for civil, commercial and subdivision projects. The system combines concrete block facing with no-fines concrete backfill to form a mass-gravity retaining structure. The specified wall arrangement, foundation, backfill and drainage details must be confirmed against the selected system and project-specific engineering. Supply-only materials are also available for contractors and installers managing their own construction.

HOW THE SYSTEM WORKS
How no-fines gravity retaining walls work.
The wall face and no-fines concrete backfill form a mass-gravity retaining structure. The combined mass resists the loads from retained ground, with the arrangement determined by the selected system and project design.
- Interlocking concrete retaining blocks form the wall face.
- No-fines concrete backfill creates the mass-gravity structure behind the blocks.
- A suitable foundation supports the wall.
- Drainage and separation details are incorporated into the engineered design.
APPLICATIONS
Applications for no-fines gravity retaining walls.
- Civil infrastructure and roadworks
- Commercial and industrial developments
- Subdivision and land development
- Terraced retaining walls and level changes
- Selected site boundary and landscape retaining applications
Suitability depends on ground conditions, wall loading, available space and project-specific engineering. Contractors, developers and engineers should confirm the selected system before ordering materials or commencing construction.

TECHNICAL INFORMATION
No-fines gravity wall technical information.
Existing reference values attributed to the Keystone No-Fines Gravity Wall drawing, based on its stated maximum surcharge of 5 kPa. Applicability to the Urbanscapes system has not yet been confirmed; these are not project specifications.
| Maximum wall height | No-fines concrete backfill depth |
|---|---|
| 800 mm | 300 mm |
| 1,200 mm | 500 mm |
| 1,600 mm | 850 mm |
| 2,000 mm | 1,050 mm |
Values apply to the drawing’s stated design conditions only and must be verified against the applicable system documentation before use. Final dimensions, foundation and levelling-strip requirements, drainage materials, pipe diameter, fall and discharge arrangements are subject to project-specific engineering. No universal pipe or discharge specification is provided here.

FAQS
No-fines gravity retaining wall FAQs.
What is a no-fines gravity retaining wall?
A no-fines gravity retaining wall uses concrete block facing and no-fines concrete backfill as a mass-gravity structure. No-fines concrete contains coarse aggregate and cement without fine aggregate; it is not the same material as loose drainage rock. The exact arrangement must match the specified retaining wall system.
Where can no-fines gravity walls be used?
They may suit civil infrastructure, commercial and industrial developments, subdivisions and selected stepped or terraced retaining applications. Suitability depends on ground conditions, loading, available space and the project design.
Does Urbanscapes offer supply and installation?
Yes. Urbanscapes offers retaining wall supply and installation, with the agreed construction scope coordinated around the selected system, engineering documentation and site requirements.
Can contractors purchase materials for their own installation?
Yes. Supply-only materials are available for contractors and installers undertaking their own construction. Contact Urbanscapes to confirm the required components, quantities and availability for the selected no-fines gravity system.
What determines wall dimensions and backfill requirements?
Wall height, soil conditions, surcharge loads, available space and the specified system influence the design. The project engineer must confirm foundation, backfill and construction requirements; the reference table on this page is not a substitute for project-specific design.
What drainage details are required?
Drainage and separation details must be established for the selected system and site. Drainage materials, pipe dimensions, fall, outlets and discharge approvals require confirmation in the project documentation. No-fines concrete and loose drainage aggregate should not be treated as interchangeable.
