We know that for construction teams, the advantages on paper are only reassuring when verified by actual projects. Especially in complex construction environments such as remote areas or harsh climates, whether the foundation free batching plant can truly solve problems, save costs and ensure progress is what you care about most. Next, we will share a real case of the AJM75 foundation free concrete batching plant in a Saudi substation project, hoping to bring practical reference for your project decision-making.
AJM75 Foundation Free Concrete Plant Serves Saudi Substation Project
The AJM75 foundation free concrete batching plant was put into use in a Saudi substation project, which fully verified the core value of its foundation free design in complex construction scenarios. The key information (focusing on foundation free advantages) is sorted out as follows:
Project pain points: The remote project site had poor ground conditions, and traditional batching plants required massive foundation construction, which would seriously delay the schedule and increase costs—this is exactly the common trouble of many construction teams.
Core solution: The AJM75’s foundation free design was selected, which does not require tedious concrete foundation pouring, perfectly matching the project’s demand for quick deployment and cost control.
Stable performance with foundation free design: On-site only simple ground leveling and hardening were needed, realizing quick installation and commissioning. Despite no concrete foundation, the integral steel frame structure ensured stable operation, and the precision measurement met the project’s quality requirements—breaking the misunderstanding that “foundation free means unstable”.
Client feedback: The client highly recognized the foundation free advantage, emphasizing that it not only saved a lot of foundation investment but also laid a foundation for subsequent site relocation (flexible transfer without abandoning foundations), maximizing equipment value.
After learning about the AJM series’ application in the Saudi substation project, we know simple ground treatment is a core advantage of foundation free batching plants. For construction teams worldwide, efficient and cost-saving ground hardening & leveling is a key concern—substandard treatment affects equipment stability, while over-investment increases budgets. Below, we share scientific and economical solutions based on professional standards and practical experience.
Core Principle: Match Standards to Needs, Avoid Blind Investment
The core of cost-saving lies in “on-demand matching”. foundation free plants rely on integral steel frames to disperse weight, so the ground only needs to meet three basic requirements: bearing capacity ≥20MPa (equivalent to C20 concrete strength), flatness error ≤3mm/m, and drainage slope ≥1.5%. There is no need to pursue excessive standards like traditional fixed batching plants.
Avoid the misunderstanding that “thicker concrete equals better”. For general operation areas, a 10cm thick C15 concrete layer plus a 15cm thick crushed stone cushion is fully sufficient—this can save 30%-40% of costs compared to using 25cm thick C30 concrete. Clarify the equipment’s actual needs first to avoid unnecessary spending.
Step 1: Scientific Site Survey & Grassroots Treatment
High-quality grassroots treatment avoids costly rework later. First, conduct a detailed site survey: if the original soil has good bearing capacity (no obvious settlement when stepped on), it can be directly compacted; for soft soil (such as cohesive soil or sandy soil with high water content), replacement and compaction are required. Instead of using expensive crushed stone, local gravel or screened construction waste can be used, which reduces cushion material costs by 20%-25%.
Use small vibratory rollers for compaction (achieving a compaction degree of 95%) instead of manual compaction (only 85% compaction degree). Mechanical compaction is 3-4 times more efficient than manual work and saves significant labor costs. For small areas or corners inaccessible to large machinery, electric compactors can be used. The cost of early compaction is only 1/5 of the cost of later rework.
Step 2: Cost-Effective Material Selection
Material costs account for 60%-70% of the total ground treatment cost. Optimize material selection for both the cushion layer and surface layer to balance quality and budget:
Cushion layer: Replace traditional crushed stone with screened construction waste (particle size ≤30mm). This substitution can reduce material costs by nearly 50% while ensuring the required bearing capacity.
Surface layer: For short-term projects (less than 1 year), a 10cm thick C15 concrete layer is sufficient; for medium-term projects (1-3 years) with frequent heavy-vehicle traffic, a 15cm thick C20 concrete layer is recommended. Adding 3-5kg of carborundum per square meter to the concrete surface can extend the ground service life by 2-3 times with only a small additional cost.
Dust control: For projects with dust control requirements, use sodium-based curing agents instead of more expensive lithium-based curing agents. This can cut dust-proof treatment costs in half while effectively improving ground hardness and preventing dust generation.
Step 3: Optimize Construction Technology
Use laser leveling robots instead of manual leveling. Laser leveling not only reduces labor costs by 60% but also lowers material wastage rate from 8%-10% (manual) to 2%-3% (mechanical), while ensuring higher flatness accuracy (error ≤2mm/m).
Adopt partitioned construction: Implement strict standards for the core area (where equipment is placed) and appropriately reduce standards for auxiliary areas (such as material stacking areas and passages), which can save 10%-15% of total construction costs. Arrange construction in a temperature range of 10-30℃ to avoid the need for expensive additives (like accelerators or retarders) and reduce subsequent maintenance costs.
Step 4: Simple Post-Construction Maintenance
Post-construction maintenance is crucial for reducing repeated investment. Cover the concrete surface with plastic film for 7-10 days of wet curing after final setting. This simple measure can effectively prevent cracking caused by water loss and extend the ground service life by 3-4 years with minimal cost.
Repair small cracks (width ≤2mm) in a timely manner with cement mortar to avoid them expanding into large potholes (which require much higher repair costs). Regularly clean the ground (especially under the equipment) to reduce wear on both the ground and equipment base.
In summary, cost-saving ground hardening and leveling for foundation free batching plants relies on scientific on-demand matching—from site survey and material selection to construction and maintenance. This approach ensures equipment stability while effectively controlling budgets. For projects with specific site conditions (such as soft soil or extreme temperatures), we can provide targeted solutions.
After clarifying the ground treatment advantages of foundation free concrete batching plants, many users will further compare them with traditional models to determine which is more suitable for their project scenarios.
