"Mark Robichaud was the most knowledge, trustworthy, and honest foundation expert I’ve ever met. He very clearly communicated issues with my crawlspace in a straightforward but non-overwhelming way. He spent an incredible amount of time inspecting, discussing and educating me on the issues and then prepared very clear, easy to understand estimates for each phase of the overall project. I feel much more educated from our meeting and highly recommend him! Thank you!"
Common Causes of your Concrete Problems in Andover
Poor Soil Compaction
The soil beneath the concrete may not have been compacted enough during construction. Over time, the loose soil shifts and settles, causing the concrete to sink or crack.
Soil Erosion
Water from rain, sprinklers, or poor drainage can wash away the soil under the slab. This creates empty spaces, making the concrete sink or become uneven.
Climate Conditions
When saturated, clay soil expands, and when dry, it contracts. These constant changes in moisture levels weaken the support beneath the concrete.
Freeze-Thaw Cycles
Water in the soil freezes and expands during winter, then thaws and contracts. This movement puts pressure on the concrete, leading to cracks or lifting over time.
Tree Roots
Roots from nearby trees or shrubs can grow underneath concrete. As they grow, they push up on the slab, causing uneven surfaces or cracks.
Heavy Loads
Parking heavy vehicles or placing large items on concrete can compact the soil underneath. Weak soil cannot often support the weight, causing the slab to sink or crack.
Poor Drainage
Excessive rainwater or water pooling near concrete slabs can lead to soil washout, weakening the soil under the concrete.
Concrete Lifting Solutions We Provide For You in Andover
The cost to lift and level a patio or porch slab can vary based on the size, condition, and location of the concrete, as well as the specific requirements of the project. Generally, costs can range from $500 to $2,500. For a precise estimate, it's best to contact local concrete lifting services for a quote.
Polyurethane foam lifting involves injecting a high-density foam beneath the concrete slab through small drilled holes. As the foam expands, it fills voids and gently lifts the slab back to its original position. This process is efficient and minimally invasive, offering long-term stabilization and support for uneven concrete surfaces.
Sidewalks or driveways become uneven or cracked due to several factors, including soil erosion, poor compaction during installation, freeze-thaw cycles, and heavy loads that cause shifting or settling. Over time, these elements can lead to cracking and uneven surfaces.
Yes, freeze-thaw cycles in Andover can cause concrete damage. When water enters cracks in the concrete and freezes, it expands, leading to further cracking and deterioration. Repeated freeze-thaw cycles can significantly weaken the structural integrity of concrete over time.
Yes, water erosion can cause concrete slabs to sink. Water erodes the soil underneath the slab, creating voids and reducing support, ultimately leading to settling or sinking of the concrete. Proper drainage and soil stabilization are key to preventing this issue.
