Landscape Drainage and External Works Planning

Coordinate levels, surface falls, retaining walls, planting, paving, subsoil drainage, rainwater and maintenance access.

Set finished levels

External levels must protect buildings, thresholds and neighbouring properties from runoff.

Separate surface and subsoil water

Paved drainage and retaining-wall drainage solve different water paths.

Choose suitable paving

Consider slip, loading, settlement, jointing, cleaning and local replacement.

Plan soft landscape establishment

Soil depth, irrigation, drainage and plant selection determine survival after handover.

Use this in Build Mart Nepal

Turn the guidance into action by creating a project, loading a BOQ, matching local providers, issuing quotations and storing approvals in the Build Mart Nepal construction operating system.

Quick implementation checklist

• Define the required outcome and acceptance evidence.
• Assign an owner and target date.
• Record quotations, approvals and changes.
• Inspect completed work and retain handover records.
