Footing and foundation systems are the base that holds an entire house. They carry the total weight of the building and safely transfer it into the soil below. In regions like New Jersey, Pennsylvania, and Delaware, homes use poured concrete or CMU block foundations because they handle thousands of pounds of load. These foundations are built below the frost line (about 36 to 42 inches deep) to prevent soil from freezing. But foundations are constantly exposed to groundwater, soil pressure, and temperature changes, which slowly increase stress over time.
In New Jersey specifically, foundation stress is even higher because the soil contains expansive clays like Illite and Kaolinite. When these soils get wet, they push against foundation walls with up to 5,000 PSF of lateral pressure. In winter, freezing and thawing cycles expand the soil by nearly 9%, repeatedly pushing and pulling against the structure. Over time, this leads to problems like cracks, sinking (settlement), soil erosion under footings, and inward bowing walls.
DryMaster Footing & Foundations Services are designed to identify and fix these problems using engineering-based solutions. DryMaster uses measurable data to choose the right repair method. For example, if a wall is bowing less than 2 inches, carbon fiber straps rated at 50,000 PSI are used to hold it in place. If a home is sinking beyond safe limits, helical pier systems are installed, driving steel shafts 20 to 30 feet deep into stable soil to support the structure. To reduce water pressure around the foundation, 4-inch perforated HDPE French drains are added to redirect groundwater. This combination of precise methods helps in long-term stability, strength, and protection for the foundation system.
What is a structural footing?
A structural footing is the lowest part of a foundation that directly supports the weight of a building. It is of concrete base, about 24 inches wide and 12 inches deep in a standard two-story home. It sits under foundation walls with steel rebar (#4 or #5, about ½” to 5/8” thick) to achieve a 3,000 PSI strength. It safely transfers the building load from the structure into the soil below.
The footing works by spreading the weight of the house over a wider area of soil so the ground does not get overloaded. A home weighing 50,000 to 100,000 pounds is distributed through a 24 inch footing instead of an 8 to10 inch wall. It reduces soil pressure of about 1,500 to 2,000 PSF. In New Jersey, footings are required to be placed at least 36 inches deep so they sit below the frost line and avoid frost heave pressure of 50 to 100 PSI. A structural footing controls uneven sinking (differential settlement) within about 1/4 inch, to prevent wall cracks, floor movement, and door misalignment over time.
What is a foundation wall?
A foundation wall is a vertical structural element that sits directly on top of the footing and forms the main support structure of a building. It is made of poured concrete or concrete masonry units (CMU). In the Tri-State area, these walls are built using 8-inch, 10-inch, or 12-inch blocks or 3,000 psi concrete. These walls rise from the footing to about 7 feet 4 inches to 8 feet in height and create the basement or crawl space.
The foundation wall supports both dead loads (permanent weight like a 15,000-pound frame and roof system) and live loads (about 40 psf from people and furniture). It transfers more than 120,000 pounds into the footing. It resists lateral soil pressure of 30 to 60 psf per foot of depth, which creates approx. 1,920 pounds of inward force on an 8-foot wall. To handle these stresses, walls are made with materials like #4 rebar in poured concrete or grouted CMU blocks with steel wire. This combination keeps the basement wall strong, stable, and within tight structural limits like 1/8-inch movement tolerance.
Why do New Jersey homes face higher foundation stress?
New Jersey homes face higher foundation stress due to a combination of expansive clay soils (Illite and Kaolinite), high groundwater levels, and strong seasonal freeze-thaw cycles. These soils exert up to 5,000 psf of lateral pressure and have a Plasticity Index of 30 to 50. In winter, soil freezes up to 36 inches deep and expands by about 9.05%. This creates frost heave forces as high as 10,000 psf that lift or shift structures. In spring, groundwater rising just 2 to 4 feet below grade pushes 50 to 100 gallons of water per day against foundation walls. This increases hydrostatic pressure and moisture intrusion from small cracks.
Older homes are more vulnerable because they use weaker 8-inch unreinforced CMU blocks, outdated drainage systems, and deteriorated waterproofing. This Mid Atlantic region needs regular inspection, crack repair, and modern drainage systems like PVC piping and vapor barriers for long-term stability.
What Are Common Causes of Foundation Failure?
The common causes of foundation failure are soil instability, water movement, hydrostatic pressure, expansive clay expansion, and freeze-thaw cycles that exceed the structural load bearing capacity of the foundation system.
5 main causes of basement failure are listed below.
Differential settlement from unstable soil compaction
Differential settlement occurs when soil beneath a foundation loses uniform strength, with bearing capacity of more than 25% across the structure. In a 2,000-square-foot home, just 1/4 inch of movement causes up to a 1/2-inch gap at door frames with structural distortion. This uneven movement weakens footing support and shifts loads onto specific foundation areas like lintels. Over time, the condition worsens as soil voids expands. Early intervention using 3.5-inch helical piers torqued to 4,000 ft-lbs installed up to 25 feet deep can restore stable load-bearing support and stop further settlement.
Footing erosion from groundwater movement
Footing erosion occurs when fast-moving groundwater washes away soil or supporting stone such as Grade 57 stone beneath a 24-inch footing. When groundwater velocity exceeds 0.5 feet per second it creates voids of 2 to 5 cubic feet under the foundation. This leaves the footing partially unsupported. The loss of support causes stress in the foundation wall and footing. It leads to visible stair-step cracks in CMU block joints and vertical cracks in walls.
To fix this problem groundwater must be controlled and redirected away from the foundation. DryMaster uses 4-inch NDS Pro-Series perforated drainage pipes connected to a 1/3 HP Zoeller M53 sump pump system. This system discharges up to 2,580 gallons of water per hour. It reduces water buildup around the footing, and restores soil stability.
Hydrostatic pressure and uplift forces
Hydrostatic pressure develops when saturated soil of 110 pounds per cubic foot pushes against foundation walls. At the base of an 8-foot wall it reaches up to 480 psf of lateral force. This force pushes water through 0.01-inch pores in CMU blocks. Over time the pressure bends the wall inward and creates structural deflection of more than 1/2 inch. Visible cracks appear as horizontal cracks in the middle section of basement walls.
To control this DryMaster installs carbon fiber reinforcement straps with 50,000 psi tensile strength at 4-foot intervals to stop inward movement and stabilize the foundation wall.
Expansive clay soil movement in New Jersey
Expansive clay soils in New Jersey expand when moisture rises from 15% to 25%. This causes volume increase of 10% to 15% and creates swelling pressure up to 5,000 psf. This pressure is more than three times the normal 1,500 psf footing capacity. During dry periods the soil shrinks and pulls away from the foundation and leaves gaps of up to 2 inches. These gaps allow sudden water entry sometimes up to 500 gallons during heavy rain. This cycle of expansion and shrinkage causes cracks in foundation walls and stair-step cracking in block joints. It leads to uneven settlement over time and long-term structural misalignment.
Frost heave and seasonal freeze-thaw cycles
Frost heave occurs when groundwater freezes at depths of up to 36 inches and expands by 9.05%. This creates upward pressure as high as 10,000 psf against foundation walls and footings. This force lifts concrete elements and causes horizontal cracks in basement walls. Repeated freeze-thaw cycles weaken concrete over time. In about 5 years the compressive strength dropped by 15% to 20% due to internal micro-cracking. This damages the structure including wall movement, cracking, and causes foundation instability.
What types of Foundation & Structural Cracks DryMaster Repair?
The main types of foundation and structural cracks that DryMaster repair are step cracks, vertical cracks, horizontal and floor slab cracks.
4 main types of foundation and footing cracks that DryMaster fixes are listed below.
Step cracks in block foundations
Step cracks also known as stair-step cracks follow the 3/8-inch mortar joints in CMU block foundations. They are signs of differential settlement. This happens when one part of the foundation drops by 1/4 inch as compared to the rest of the structure. When the crack width exceeds 1/8 inch it allows water and radon gas to enter the basement. These cracks appear in basement walls and corners where load is not evenly distributed. They show that the footing is losing uniform soil support.
DryMaster fixes this by installing Model 350 steel push piers or helical piers. These piers are placed 20 feet deep into soil to bypass weak ground in foundation.
Vertical cracks in poured or block walls
Vertical cracks form due to concrete shrinkage during the first 28 days of curing. These cracks are 1/16 inch thin, still moisture enters through it. Over time they become water entry points if left untreated. They remain stable but get wider under soil pressure or temperature changes.
DryMaster repairs these cracks using high-pressure polyurethane injection. The material expands at a 20:1 ratio and fills the full 8- to 10-inch wall thickness. This restores both strength and waterproofing in the wall.
Horizontal cracks from lateral soil pressure
Horizontal cracks appear in the middle third of basement walls about 3 to 5 feet above the floor. They form when lateral soil pressure or hydrostatic force is high. These cracks develop when the wall bows inward by 1 to 2 inches. This means the wall is under structural stress and is losing strength. This condition is serious because it shows active movement in the foundation.
DryMaster stabilizes these walls using carbon fiber reinforcement straps such as StablWall or Fortress systems. These straps have tensile strength up to 50,000 psi which is about 10 times stronger than steel. They lock the cracks in place and stop further inward movement in basement walls.
Floor slab cracks and heaving
Floor slab cracks occur when a 4-inch concrete slab loses support from the Grade 57 stone base or is pushed upward by expansive clay soils like Kaolinite. Even a small lift of 5 millimeters creates tripping hazards and causes cracks in non-load-bearing walls. These problems start when soil voids form or moisture expands beneath the slab.
DryMaster repairs this using polyurethane foam injection also called slab jacking. A high-density polymer is injected through 5/8-inch holes under the slab. The foam expands with a lifting force of up to 6,000 psf. It levels the slab within a 1/16-inch tolerance and fills all underground basement cracks.
What Structural Remediation Methods DryMASTER Uses?
DryMASTER uses structural remediation methods to fix footing and foundation walls instability. These structural methods are steel pier installation, injection filling in cracks, CFRP system, restoring mortars and ffixes drainage system.
The structural remediation methods that DryMaster uses are listed below.
Underpinning and steel pier installation
Underpinning and steel pier installation is used when a foundation sinks up to 1/4 inch over a 10-foot span. DryMASTER installs Model 350 steel push piers or helical piles with diameters of 2.875 inches or 3.5 inches. These piers are hydraulically placed in the ground of 4,000 to 8,000 ft-lbs of verified torque or load capacities of 50,000 to 100,000 lbs. They transfer the full structural load to stable soil layers 20 to 30 feet below grade. This stops differential settlement, corrects sinking, and restores structural alignment. It is combined with drainage or wall reinforcement when water pressure or soil movement is present.
Structural crack injection systems
Structural crack injection systems are used to seal foundation cracks of 0.005 inches. DryMaster installs injection ports every 8 to 12 inches in the crack line and fills them with polyurethane or structural epoxy. The polyurethane expands at a 20:1 ratio and blocks water entry. The epoxy cures with a compressive strength of 8,000 to 12,000 psi, which is up to 4 times stronger than standard concrete. This system fixes water leaks, capillary seepage, and non-moving structural cracks. It restores both waterproofing and structural continuity across the damaged wall section.
Carbon fiber reinforcement (CFRP systems)
Carbon fiber reinforcement systems use ultra-thin straps of 0.045 inches thick but with 50,000 and 90,000 psi tensile strength. DryMaster bonds these straps to foundation walls using structural epoxy at 4-foot spacing. This system is used when walls show 1/2 inch to 2 inches of inward bowing caused by soil or hydrostatic pressure. It stops further movement without excavation or bulky steel beams that take up interior space. The fixed wall stabilizes and prevents additional deflection.
Footing and wall interface sealing
Footing and wall interface sealing targets the cove joint where water enters the basement. This joint allows 2 to 3 gallons of water per day through capillary suction. DryMaster seals this area using hydrophilic crystalline sealers or 20-mil reinforced vapor barriers. It is combined with a 4-inch perforated HDPE drainage system placed in Grade 57 stone. This repairing system blocks water entry at the weakest structural point and reduces long-term hydrostatic pressure at the base of the wall.
High-strength parging and restoration mortars
High-strength parging and restoration mortars repair damaged CMU surfaces with a protective 1/4-inch to 1/2-inch layer. These mortars have a minimum compressive strength of 3,000 psi and bond directly to weakened masonry. This method fixes spalling, surface erosion, and delamination caused by efflorescence, which wear down block surfaces by up to 1/8 inch over time. It restores wall strength and protects the foundation surface from deterioration.
Drainage integration for pressure relief
Drainage integration systems reduce hydrostatic pressure by redirecting groundwater away from foundation walls. DryMaster installs 4-inch perforated HDPE or Schedule 40 PVC pipes at a minimum 1% slope leading to a sump basin. The system uses a 1/3 HP or 1/2 HP Zoeller M53 pump capable of discharging 2,580 to 3,240 gallons per hour. By removing excess water, it reduces pressure from up to 480 psf to near zero. This prevents water intrusion, and relieves structural stress.
