Borelog sheet drawn live
Type the field data and the sheet redraws instantly — depth ruler, soil symbols, sample column, groundwater marker and the N-value profile, paginated for A4.
SPT and sampling table
Record 15 cm blow counts or a direct N-value, sample IDs, disturbed and undisturbed types, and lab results (fines, LL, PI, qu, moisture) per depth.
Strata with soil symbols
Seven soil types — clay, sand, silt, gravel, fill, organic and rock — with hatching, colours and bold USCS group symbols such as CL, SM and GW.
Import your existing sheets
Excel and CSV import with a column-mapping dialog: any heading, any order. Files with only an N-value column work too.
Projects and boreholes without limits
One file holds several projects, each with unlimited boreholes. Export every borehole in a project to a single, correctly paginated PDF.
Your company letterhead
Logo, address, accent colour and four header layouts, plus dual X/Y and latitude/longitude coordinates on every log.
