Your home’s foundation is the most important structural element of your property. When it begins to crack, shift, settle, or allow water intrusion, your entire home is at risk. At On Top Masonry & Construction, we provide professional foundation repair, crack sealing, wall reinforcement, waterproofing, and structural stabilization services across New Jersey.
With 20+ years of experience, our team specializes in diagnosing and repairing foundation problems caused by New Jersey’s challenging soil conditions, freeze–thaw cycles, heavy rainfall, groundwater pressure, and aging construction.
If you’ve noticed cracks, bowing walls, uneven floors, or moisture in your basement — your foundation needs immediate attention. We provide fast, reliable, and long-lasting solutions designed to protect your home for decades.
New Jersey homes experience a wide range of foundation issues due to shifting soil, water intrusion, and climate fluctuations.
Foundation problems get worse over time — early repair is critical.
We provide full-service foundation repair tailored to your home’s needs.
Cracks allow water to enter and weaken the foundation. We professionally seal cracks using Epoxy injection for structural stability. Urethane injection for waterproofing and leak prevention. This prevents further expansion and stops water infiltration.
Bowing or leaning walls are caused by soil pressure and groundwater force. We stabilize walls using Carbon fiber straps (stronger than steel, non-invasive), Wall anchors, and Steel I-beams. These solutions prevent collapse and restore structural safety.
Underpinning strengthens and lifts sinking or settling foundations. We install: Helical piers, Steel push piers. These support the home on solid, stable soil layers and prevent further movement.
If your block foundation walls are deteriorated, collapsing, or structurally compromised, we rebuild damaged sections using: High-strength concrete block, Reinforced masonry, Waterproof mortar systems
Foundation problems and water issues often go hand in hand. We offer: Interior waterproofing, Exterior foundation waterproofing, French drains, Sump pump installation, Vapor barriers, and Wall sealing. This keeps your basement dry year-round.
Poor drainage is one of the biggest culprits behind foundation damage. We correct grading and install drainage systems to direct water away from the home.
