The foundation of a system that works
A percolation (perc) test measures how quickly water drains through your soil — the single most important factor in sizing your drainfield and choosing your system type. We run the test, document the results, and design your system around them, so it's approved by the county and built to perform for decades.
What we test
Soil texture and class, depth, and how quickly your ground absorbs water across the proposed drainfield area.
Why it matters
Your soil class sets the drainfield size and whether you need a conventional or aerobic system — it drives the whole design.
We design around it
We document the results and engineer a permitted system matched to your actual site conditions.
