A Settled Front-Porch Corner, Chaeng Watthana — Fixed with a Single Micropile

Not every settlement needs the whole house underpinned — sometimes the problem is a single spot. The front porch of this home in Chaeng Watthana, Nonthaburi had settled only at the corner by the column, stepping down and starting to split. URETEK assessed that one micropile, right at the spot, was enough — no need to over-engineer.

🚪 The Problem: One Settled Porch Corner

The porch floor at the column corner had dropped into a step against the original slab — both a trip point and a sign the soil under that corner was carrying load unevenly.

🎯 The Choice: Fix the Spot, Not the Whole Line

The engineers laser-leveled to confirm the settlement was limited to one corner, then chose to add just a single micropile at that spot — saving time and budget while still fixing the true cause.

⚙️ The Fix: One Micropile at the Porch Column Base

A small pit was opened at the porch column base, a load bracket fixed to the footing, and a steel micropile (ASTM A53 tube) hydraulically jacked down to firm strata, the gauge confirming its capacity.

📊 A +6 mm Lift, Precisely Controlled

Because this corner had dropped more than the rest, it needed a +6 mm lift — the team raised it gradually, checking levels until the porch was flush again, logging the values (340 bar, 24 m deep, +6.0 mm) before locking the pile head and concreting the floor shut.

✅ The Result: A Level Porch, Done in a Day

With the load on the pile, the porch was flush and level again with no step to trip on — neatly restored within a single day, backed by a 24-month warranty. Proof that a small, localized settlement can be fully fixed before it spreads.
