Foundation Construction & Waterproofing

Foundation Construction & Waterproofing

A strong, dry foundation is the cornerstone of any safe and lasting structure. At TNT Construction and Waterproofing Company, we provide expert foundation construction and comprehensive waterproofing services for residential and commercial clients in New York. Our team ensures every project meets the highest standards for structural integrity, moisture protection, and long-term durability.

Foundation Construction

Our team constructs both shallow and deep foundations, tailored to your site’s soil conditions, building size, and structural requirements. Shallow foundations-such as slab-on-grade, footings, and grade beams-are ideal for structures where loads can be distributed close to the surface. For larger or heavier buildings, or sites with poor soil, we build deep foundations like piles, caissons, and drilled shafts to transfer loads to stable ground or bedrock

    Foundation Construction Services

    We handle all aspects of foundation construction, including:

    • Site Assessment & Preparation:
      Our process begins with a thorough evaluation of soil conditions, grading, and drainage to ensure a stable base for your new foundation.

    • Pouring & Building Foundations:
      We construct durable concrete foundations for new homes, additions, and commercial buildings. Our team is experienced in slab, crawl space, and basement foundations, using high-quality materials and proven techniques for reliable results.

    • Structural Repairs & Reinforcement:
      If your existing foundation shows signs of settling, cracking, or shifting, we provide professional repairs and reinforcement to restore stability and prevent further damage2.

    Foundation Waterproofing Solutions

    Protecting your foundation from water intrusion is critical for preventing structural damage, mold, and costly repairs. Our waterproofing services include:

    • Exterior Waterproofing:
      We apply advanced waterproofing membranes and coatings to the exterior of new or existing foundation walls. This barrier prevents moisture from penetrating the concrete and entering your basement or crawl space345.

    • Foundation Drainage Systems:
      Proper drainage is essential for keeping water away from your foundation. We install drain tiles, French drains, and sump pump systems to efficiently channel water away from your property, reducing hydrostatic pressure and the risk of leaks5. 

    • Interior Waterproofing & Crack Repair:
      For existing foundations, we offer interior solutions such as epoxy crack injections, interior drain tile systems, and moisture barriers to address leaks and seepage from inside the basement34.

    • Sump Pump Installation & Maintenance:
      We install and maintain sump pumps to ensure your basement remains dry even during heavy rains or rapid snowmelt34.
