What Is Foundation Repair?

Foundation Techniques

1. Sealants & Masonry Patches

2. Slab Jacking, Mud Jacking, Concrete Lifting, and Slab Leveling

2.1. Ponderous Mud or Concrete Mixture

2.2. Polyurethane Resins

Advantages of Polyurethane Resins

1. This method is suitable for tyrannical weather conditions.
2. No tincture change in the structure as the new concrete blend is spread beneath the old slab layer.
3. It isn’t required to clean up the place as this method doesn’t mess up the place in comparison to the rest.
4. The new concrete blend strengthens base for the old one.
5. No wastage & sound pollution in comparison to replacement of a new structure. This method is suitable for tyrannical weather conditions.

Disadvantages of Polyurethane Resins

3. Pressed Concrete Piling

3.1. Concrete Piers

• In a location where a pier needs to be set up, an aperture (Depth-12-20 feet & Diameter-12 inches) is bored down to the target depth.
• Reinforcing steel bars are fastened together & are lowered down to the aperture.
• Concrete solidifies in 7 days & hydraulic jacks are utilized to pull up the foundation.
• Just after that, steel & concrete spacers are fixed on the piers to hold up foundation & the hydraulic jacks are detached.
• Final step- hide the piers.

3.2. Concrete Pilings

• In each location where a pilling is required to be installed, an aperture (Depth-2 feet & Diameter- Doormat) is dug adjacent to the foundation.
• A concrete cylinder is set up at the bottom of the aperture & beneath the foundation.
• High power hydraulic ram is then set up on loft of the cylinder & hence top of the ram gets in contact with the underside of the foundation.
• Ram activates & is utilized to get in contact with the cylinder deep down to the bottom.
• A cylinder is pushed at the bottom, then, another cylinder is fixed above the primary cylinder & this press continues until reinforcement.
• Finally, a cap placed on the loftiest of the column & a concrete cylinder is set up above the cap.
• When all of the cylinders are set up, hydraulic jacks set up on the caps & utilized to lift the foundation.
• Final step- hide the pilings.

Advantages of  Pressed Concrete Piling

1. The cost is low, with no ponderous equipment requirement.
2. Not much planned due to the slab jacking methodology.

Disadvantages of  Pressed Concrete Piling

4. Poured Concrete Piers

5. Belled Concrete Piers

Advantages of  Belled Concrete Piers

1. Provides significant brawn because it is reinforced.
2. Bell-shaped bottom intercepts the piers from unwanted movements within soil layer.
3. The piers are required to be stiffened much before the completion of project & takes longer.

Disadvantages of  Belled Concrete Piers

6. Steel Piers

1. The ground is dug to install the piers round the foundations.
2. The foundation bracket is mounted.
3. Push Piers are installed.
4. The weight of the structure is conveyed to the steel piers.

7. Helical Steel Piers

8. Prof-lift System

9. Soil Injection

10. Root Barriers

• Excavating a ditch.
• Laying the barrier substance in the ditch.
• Refilling the trench.

• Concrete piers
• Concrete pilings
• Mud jacking
• Soil injection
• Root Barriers

11. Segmented Piers

12. Spot Piers

13. High-density Polyurethane Foam

Which Parameter Cause the House Foundation Problem?

1. It was developed on expansive clay (i.e. soil is high in clay content)
2. It was built on unstable & improperly compacted fill soils (soil components start to expand or shrink due to sogginess)
3. Area around the foundation possesses poor drainage or water logging issues (plumbing leaks) in areas.
4. The structure is a built-in area with tyrannical seasonal changes.
5. Witnessing a plumbing leak beneath your home.
6. Tree roots are growing adjacent to your home.
7. An earthquake, flood, or drought comprised the structure.
8. Sudden exertion of unnatural forces.
9. Uneven movement at the soil layer after settlement of foundation.

What Causes Foundation Issues?

Causes of Foundation Damage and Repair Solutions

1. Soil movement: Expansive soil, which expands when wet and contracts when dry, is a common cause of foundation damage. This movement exerts pressure on the foundation, leading to cracks and shifting. Proper drainage systems and soil stabilization techniques, such as installing French drains or using soil additives, can help mitigate the effects of soil movement.
2. Water damage: Excessive moisture can erode the soil beneath the foundation, causing it to settle or sink. Poorly designed or malfunctioning drainage systems, leaky plumbing, or inadequate waterproofing can contribute to water damage. Repair solutions may include fixing drainage issues, installing or repairing gutters and downspouts, and ensuring proper grading around the foundation.
3. Poor construction: Foundations that are inadequately designed or constructed can be prone to damage. This includes issues like insufficient reinforcement, improper compaction of soil, or the use of low-quality materials. Repair solutions may involve reinforcing the foundation with additional support, such as underpinning or helical piers, and addressing construction deficiencies.

Common Foundation Issues and Repair Techniques

• Polyurethane Foam Jacking. This foundation repair process uses polyurethane foam material to lift and support a sunken concrete slab foundation.
• Concrete Pressed Piling.
• Steel Piers.
• Helical Piers.
• Concrete Piers.
• Slabjacking/Mudjacking.

DIY Foundation Repair Tips and Step-by-Step Guide

1. Identify the Issue: Look for signs of foundation problems such as cracks in the walls, uneven floors, sticking doors or windows, or gaps around windows and doors. Determine the severity of the problem to decide if it's within your DIY capabilities.
2. Gather Information: Research the type of foundation you have (e.g., concrete slab, pier and beam) and familiarize yourself with common foundation problems and repair techniques.
3. Address Drainage Issues: Poor drainage is often a leading cause of foundation problems. Ensure that your gutters and downspouts are clean and direct water away from the foundation.

How Foundation Repair?

1. Inspection: A professional foundation repair contractor will conduct a thorough inspection of the foundation to identify any existing problems, such as cracks, settlement, or shifting. They may use various tools and techniques like laser levels, surveying equipment, or soil tests to assess the condition of the foundation.
2. Diagnosis: Based on the inspection findings, the contractor will determine the underlying cause of the foundation issues. Common causes include soil settlement, poor drainage, expansive soils, plumbing leaks, or improper construction.
3. Repair Plan: Once the cause is identified, the contractor will develop a repair plan tailored to the specific foundation problems. The plan may involve one or more repair techniques depending on the severity of the damage and the type of foundation.
