Documenting Drainage and Base Conditions in Wet Weather

Read the site as a set of observations

Start with the whole property rather than a single puddle or soft-looking patch. Photograph the building edge, drive or walk surface, low points, slopes, shoulders, drains, downspouts, walls, stairs, and adjoining ground. Note the date and weather context, then describe what is visible without assigning a technical cause.

A wide view helps show how a proposed surface relates to doors, garages, curbs, landscaping, neighbouring lots, and pedestrian or vehicle routes. Add closer views of water marks, sediment, exposed aggregate, soft edges, displaced material, or standing water only when those features are visible. A clean record distinguishes a temporary wet appearance from a repeated observation.

Observations and photos are not an engineering diagnosis. They cannot confirm soil layers, underground utilities, structural movement, capacity, or the right drainage arrangement. Site conditions vary with grade, materials, prior work, weather, and neighbouring water paths, so keep a note of what was not visible or could not be accessed.

Follow the visible water path

When water is present, record where it appears to start, where it travels across or beside the surface, and where the visible path ends. Photograph the upstream and downstream context where it is safe to do so. Use words such as ‘appears to collect’ or ‘was visible moving toward’ rather than claiming that the path explains damage.

Look for changes at downspouts, drains, swales, curbs, wall edges, driveway aprons, and transitions between asphalt, pavers, concrete, gravel, and soil. Note whether the feature was seen during rainfall, after rainfall, or during dry conditions. The timing can help a later discussion understand the observation without turning it into a performance claim.

If water crosses a shared route or enters another property, record the general relationship and the access or communication requirement. Do not move covers, enter restricted areas, or disturb soil to investigate. When the visible route disappears underground or behind a wall, identify that as an unknown requiring appropriate review.

Describe grade and base without prescribing a build-up

Record visible changes in level and direction. A long view along a driveway, walkway, or patio can show a high point, low point, crossfall, or transition, while a side view can show how the surface meets a threshold or curb. Use approximate measurements only when you can explain the reference points and the limits of the reading.

For base-related observations, photograph exposed edges, existing excavation, loose or saturated-looking material, settlement, rutting, or a change in surface level. Do not infer the depth, compaction, bearing condition, or material identity from colour or texture alone. Those questions may require a more suitable site review and should remain open in the request.

Describe what surface work is being considered—such as asphalt, pavers, concrete, gravel, a wall, or an exterior renovation connection—without assuming that the finished surface decides the underlying preparation. The purpose of the record is to identify relationships and unknowns for discussion, not to select a build-up from a photograph.

Photograph edges, transitions, and access

Edges often provide useful context. Photograph where the surface meets a garage, sidewalk, lane, curb, wall, stair, planting bed, fence, or neighbouring material. Include a wider view showing who uses the route and a closer view showing visible separation, settlement, erosion, cracking, or loose material, if present.

Record access for people and vehicles in general terms: a narrow side passage, shared entrance, parkade, loading area, gate, stair route, or occupied driveway. If a strata council, property manager, tenant, or neighbour controls the area, note the permission or notice process. These details shape the questions that need to be answered before any work can be discussed responsibly.

Keep people, private documents, security devices, and unrelated property details out of photographs where possible. Save original images, avoid filters, and label the direction or area. A consistent set of files makes it easier to compare the visible context without overstating what the images show.

Organize a site discussion request

A useful request can include the property type, general location, surface under consideration, date and weather context, wide views, close-ups, approximate measurements, visible water paths, adjoining edges, access notes, and a short list of unanswered questions. Include any known history as a report from the property owner or manager, not as a verified technical finding.

The resulting package is an educational planning record. It can support a focused conversation about what needs to be confirmed, while leaving engineering diagnosis, design decisions, material selections, and construction outcomes to the appropriate site-specific process.
