OneOverview
Most factories in Indonesia are located in coastal areas with soft soil, backfill, and hydraulic fill, characterized by low bearing capacity. Heavy rainfall soaking and equipment loads easily cause settlement. Treatment methods are divided into two categories based on whether production stops and whether the solution is temporary or permanent (non-stop production & temporary measures, stop production & permanent solutions), adaptable to the actual needs of Indonesian factories for continuous production, complex soft soil conditions, and varying budgets.
II. Three Major Methods for Factory Floor Settlement Treatment and Their Pros and Cons (Adapted to Indonesia’s Conditions)
(1) Non-stop production · Symptomatic treatment ( FastSpeedEmergency response without delaying production)– Floor lifting and leveling
Method: Drill small holes in the floor and inject grout into the foundation to compact Indonesia’s soft soil/backfill, fill voids, and simultaneously lift the settled floor, with minimally invasive construction both indoors and outdoors throughout the process.
Advantages: Construction without stopping production, localized work does not affect equipment operation or goods storage, economical.
Disadvantages: The primary goal is to level the settled floor without addressing the root cause of settlement. Over time, settlement may recur, failing to resolve the fundamental issue.
Application scenario: Temporary transitional use for factory buildings requiring quick resumption of production.
(2)Discontinued・Radical Treatment (Settlement Stopping + Repair in One Step, Permanent Solution)—Pile+Beam and SlabGround slab underpinning
Method: Cease production, evacuate the area, level and break the ground on-site, drive in ground piles (reinforced concrete square piles), and simultaneously pour new ground beams at the pile heads while casting a new monolithic ground slab. The ground load is transferred to deeper hard soil layers via the ground piles.
Advantages: Permanently stops settlement, resists soil creep in Indonesian soft soil and heavy rain immersion, with no secondary settlement.
Disadvantages: Requires production stoppage and evacuation, costs more than ground leveling and lifting, and has a slightly longer construction period.
Suitable Scenarios: Heavy-duty machinery factories, storage and logistics warehouses, industrial buildings with severe settlement.
III. Summary
For factory ground settlement where production cannot be halted, opt for ground leveling and lifting as needed to maintain operations. If production can be paused, it is recommended to use pile + beam-slab ground replacement for a one-time, permanent solution.
