Warehouse Floor Casting Project in Bandung Using Geotextile Fabric for Strong Foundation

One effective method applied in warehouse floor casting projects in Bandung to improve foundation performance is the use of 200–250 GSM non-woven geotextile, helping minimize the risk of soil settlement more effectively.

Warehouse floor casting is often considered the final stage of construction, even though the long-term performance of the floor highly depends on the condition of the subgrade and aggregate base beneath the concrete slab.

In Bandung, varying soil conditions, unevenly compacted fill material, and moisture changes caused by rainfall can weaken the foundation. These conditions may lead to soil settlement, floor cracking, and uneven surfaces that can disrupt forklift operations and warehouse logistics activities.

The use of 200–250 GSM non-woven geotextile as a geotextile fabric for warehouse floor applications helps improve foundation stability through its separation, filtration, and drainage functions, while also supporting concrete base reinforcement performance and reducing the risk of damage to the warehouse floor system.

Why Warehouse Floors in Bandung Are Highly Sensitive to Soil Settlement

Warehouse floors face much heavier demands than typical building floors. They carry static loads from racks and stacked goods, plus repetitive dynamic loads from forklifts, hand pallets, and loading/unloading trucks. 

Because traffic repeatedly follows the same paths, loading docks, turning areas, and main corridors, the subgrade is stressed in the same zones over and over. 

In parts of Bandung, the soil can be soft or uneven, especially where backfill compaction is not uniform, so repeated loading may cause gradual deformation. Over time, this shows up as depressions or surface waves, cracking near joints and high-load areas, and joint damage.

That’s why settlement prevention must start at the foundation. A major driver of base instability is fine subgrade soil migrating into the aggregate layer during damp or waterlogged conditions. Once fines contaminate the aggregate, interlock weakens, base strength drops, and settlement progresses faster.

When is 200–250 GSM Woven Geotextile Applied for Warehouse Foundation Reinforcement?

This non-woven geotextile (200–250 GSM) is installed during the warehouse foundation construction phase, not after the building is already in operation.

1. After Subgrade Cleaning and Leveling

Non-woven geotextile is installed after the subgrade has been cleaned, leveled, soft spots have been repaired, and the surface has been properly compacted. This stage is particularly important considering Bandung’s soil conditions, which can vary, remain moist, or have uneven fill compaction.

With a properly prepared subgrade surface, the geotextile can remain more stable on top of the soil, reducing the risk of shifting, wrinkling, or damage during aggregate placement.

2. Before Base Course Aggregate Placement

After the subgrade is properly prepared, the non-woven geotextile is rolled out to cover the working area with sufficient overlap at the joints. At this stage, the geotextile begins functioning as a separator, filter, and drainage layer.

Its main function is to prevent the subgrade soil from mixing with the aggregate during base course installation, helping maintain aggregate quality and overall foundation stability through the performance of a soil separation fabric system.

3. Before the Concrete Casting Process

After the geotextile is covered with aggregate and the base layer becomes stable, the aggregate is compacted before continuing with the installation of plastic sheeting or lean concrete, followed by wiremesh or reinforcement placement and concrete slab casting.

With this system, the foundation becomes more stable, helping reduce the risk of cracking caused by soil settlement over time while improving concrete base reinforcement performance.

Main Functions of 200–250 GSM Woven Geotextile in Maintaining Warehouse Floor Stability in Bandung

Because the impact of an unstable foundation can significantly affect warehouse operations, many contractors and warehouse owners choose to use 200–250 GSM non-woven geotextile as a geotextile fabric for warehouse floor systems to help maintain the stability of the base layer because:

1. Better Drainage, Filtration, and Separation Performance

Warehouse floors are sensitive to moisture changes beneath the concrete slab. If water is trapped under the aggregate layer, soil bearing capacity can decrease and settlement may occur over time.

A 200–250 GSM non-woven geotextile has higher permeability than woven geotextile, allowing water to drain more effectively, reducing pore water pressure, and helping maintain foundation stability. It also retains fine soil particles and prevents them from migrating into the aggregate layer.

By functioning as a soil separation fabric, non-woven geotextile helps maintain aggregate cleanliness and interlock, reducing the risk of surface waviness, settlement, and instability caused by forklift traffic and warehouse operations.

2. Helping Reduce the Risk of Cracking and Settlement

With better separation and drainage performance provided by 200–250 GSM non-woven geotextile and its specialized fiber structure, the aggregate layer beneath the warehouse floor can maintain its density and stability for a longer period.

This is important because it helps reduce the risk of localized settlement, improves concrete slab stability, and minimizes the potential for cracking caused by soil settlement.

That is why, in warehouse floor casting projects in Bandung, non-woven geotextile is often preferred when the main objective is to maintain foundation stability under moist soil conditions, improve concrete base reinforcement, and prevent long-term settlement.
