Concrete Foundation Services in North Tonawanda, NY

In North Tonawanda and the surrounding Western New York area, footings need to be established below the frost line to prevent movement caused by seasonal freezing and thawing of the soil above them. The frost depth in this part of New York State is typically around 48 inches, meaning footings need to be at least four feet below finished grade to be considered adequately protected from frost heave. The exact depth required for a specific project may be influenced by local soil conditions, the bearing capacity of the soil at the site, and the requirements of the local building department. We confirm the appropriate footing depth for every project during the planning phase and ensure the work meets all applicable local requirements.

A poured concrete foundation is formed using steel or aluminum forms into which concrete is poured as a single continuous wall, producing a monolithic structure with no joints or seams in the wall itself. Poured concrete walls are generally stronger in resisting lateral soil pressure, easier to waterproof effectively, and less prone to water infiltration than block walls because there are no mortar joints for water to work through.

A concrete block foundation, also known as a concrete masonry unit or CMU foundation, is constructed by laying individual concrete blocks in courses with mortar joints between them. Block foundations have been used successfully for many decades and remain a practical option in certain applications, particularly for additions and accessory structures. Each approach has its appropriate applications, and we discuss the options that make most sense for your specific project during the assessment and planning phase.

Not all foundation cracks are equally serious, but none of them should be ignored without at least having them assessed by an experienced contractor. Hairline vertical cracks that appear shortly after a poured foundation has cured are often the result of normal concrete shrinkage and may only require sealing to prevent water infiltration. Wider vertical cracks, cracks with noticeable displacement between the two sides, and any crack that appears to be actively growing are more serious and warrant prompt evaluation.

Horizontal cracks in foundation walls are the most concerning type and indicate that the wall is experiencing lateral pressure from the surrounding soil that is exceeding its design capacity. This type of crack should be assessed immediately, as a wall under that kind of stress can progress to the point of structural failure if left unaddressed. Stair-step cracks in block foundations and any cracking accompanied by visible bowing or deflection of the wall also require prompt professional attention. When in doubt, have it looked at. The cost of an assessment is negligible compared to the cost of addressing a foundation problem that has been allowed to progress.

Yes, exterior waterproofing and drainage measures are incorporated into our foundation installations as a standard part of the work rather than as an afterthought. A foundation wall that has been properly waterproofed on the exterior face and is protected by a functioning perimeter drainage system manages groundwater correctly and remains dry on the interior over the long term. We apply waterproofing membrane to the exterior face of the foundation walls before backfilling and ensure that perimeter drainage is correctly established to carry water away from the foundation rather than allowing it to build up against the wall.

For existing foundations where water infiltration is occurring, we assess the source and pathway of the moisture before recommending a remediation approach. In some cases, exterior excavation and waterproofing is the most effective long-term solution. In others, interior drainage systems combined with crack sealing can manage the issue effectively. We give you an honest assessment of the options and their relative effectiveness for your specific situation so you can make an informed decision.
