Reading Water Before Moving Earth
Standing water on a plot has a cause, and that cause can be measured. We survey how water arrives, where it collects, and what a soil profile can actually absorb — then draw a layout from what we find, not from a guess.
Data Before Recommendations
Every plot holds water differently depending on what sits under the topsoil. Rather than proposing a fixed package, we start with spot levels, test pits, and infiltration readings, so any layout that follows is sized to the ground it will sit in. This means the drawing you receive reflects your plot's own behaviour, not a standard assumption.
Based in Yokohama and working across plots of varying size, we keep the process transparent: you see the readings, the reasoning, and the resulting plan before any material is ordered.
What Each Layout Accounts For
Soil Profile
Test pits expose clay, gravel, and topsoil bands so lateral spacing can be set against measured permeability rather than assumption.
Seasonal Water Table
The depth recorded on survey day is placed against a wider seasonal pattern, so a dry-week reading isn't mistaken for the full picture.
Discharge Capacity
A run is only as good as where the water ends up — receiving capacity at the outfall is checked before a fall is drawn.
How a Plot Moves From Question to Drawing
You describe the plot and what you're seeing — standing water, sinking paths, a slope that's begun to slip.
A survey or advisory visit is scheduled, with levels, pits, or an auger walk depending on the issue.
Findings are set out plainly, including cases where drainage work isn't warranted at all.
Where work is justified, a drawing and materials schedule are prepared for you or your contractor.
