To level a pool on uneven concrete, a common method is to address the high points on the concrete surface.
When dealing with an uneven concrete slab where a pool is to be placed (such as an above-ground pool or the area around an inground pool deck), one effective strategy is to reduce the height of the elevated areas.
Addressing High Spots
As suggested by experts, instead of solely trying to raise the low areas of the concrete slab, you can grind down the high spots to achieve a level surface for your pool or pool deck area.
- Process: This involves using a concrete grinder, a specialized tool designed to abrade and smooth concrete surfaces. By carefully grinding the peaks or high areas, you can gradually bring them down to match the level of other parts of the slab.
- Execution: You have two main options for this task:
- Hire a Professional: A contractor specializing in concrete work or surface preparation can perform this job efficiently using professional-grade equipment.
- Do It Yourself: For DIY enthusiasts, concrete grinders can typically be rented from tool rental centers. Ensure you understand how to safely operate the equipment and wear appropriate personal protective gear (like masks and eye protection) as grinding concrete creates significant dust.
This method is particularly useful when the elevation differences are not extreme and the goal is to create a stable, flat base or surround for the pool structure.
Other Potential Considerations (Depending on Severity)
While grinding addresses high points, dealing with significant low spots might require different approaches, which could include:
- Self-Leveling Underlayment: For shallow dips, a self-leveling concrete overlay or underlayment could be poured over the entire surface after grinding down high spots. This material flows to fill low areas and creates a smooth, level plane.
- Mudjacking or Slabjacking: For larger voids or significant sinking (which might indicate a sub-base issue), methods like mudjacking or polyjacking inject material under the slab to lift and level it. This is a more involved process typically requiring professional service.
- Slab Replacement: In cases of severe cracking, major unleveling, or significant structural issues with the concrete, replacing the slab might be the most durable long-term solution.
Choosing the right method depends on the degree of unleveling, the size and type of the pool, and your budget. Always ensure the final surface is not only level but also structurally sound to support the weight of the pool and water.
