FAQs

Only Contractors supplied and trained by GridLock Foundations are permitted to install them. Otherwise, training and on-boarding is simple. Contractors must follow local laws and building codes.

Contact us and we will forward your information to an installer if we have one in your area.

We only sell GridLock systems in pallet increments. GridLock Plates are packaged with 42 per pallet. GridLock Stabilizer Kits are packaged with 32 per pallet.

The steel in the GridLock Foundations is designed to maintain structural integrity forever. Concrete can crack under pressure at any point in its lifetime but generally lasts forever. Concrete that is not reinforced with an adequate rebar system is not recommended for any structural purposes. Power vibration of concrete is recommended for maximum strength; a requirement for installing GridLock Foundation Stabilizers.

There are many potential reasons why floors slope. Overspanned floor joists, over-spanned beams, sinking piers, cracked wood, poor construction, and wood rot are a few causes. Ultimately, sloping floors occur because the structure lacks adequate support and needs more structural strength.

Cracks may appear on drywall when the floor support from below is sinking. Oftentimes, it means the structure lacks adequate support. Sometimes, drywall cracks can be cosmetic, so it’s important to have an experienced crawl space foundation repair professional or structural engineer assess the cracks.

Cracks form in bricks and block when the foundation is distressed. This usually means the existing foundation is inadequate to provide stability for the home, so the foundation settles. Sometimes, cracked bricks are a sign of swollen window or door lintels, so it’s important to have an experienced crawl space foundation repair professional or structural engineer assess the cracks.

Lift with ANY foundation piers is NOT recommended. Lift causes damage via ‘load reversals’. The soil loses 100% contact from the foundation, eliminating the foundation & soil support. Lifted, all of the foundations load (weight) is resting on 3” circular steel pipes, on 3” of deep soil. Most soils can only support 1,000-2,000 pounds per square foot (12”x12”). For this reason, lifted foundation piers can be prone to re-settlement. Lifting foundations causes damage in many instances. Cracked masonry, drywall cracks, etc. are common with lift. In some cases, severe structural failure has occurred due to lift.

No. WARNING: We highly recommend against lifting foundations off supporting soils. Lifting foundations eliminates all support from the existing foundation and soil. A firm solid connection between the foundation and soil is required to provide support.

Yes, resistance push piers & helical piers can be very useful in stabilizing foundations. The Best Practice is, if you CAN use GridLock Stabilizers, you SHOULD use GridLock Stabilizers. Otherwise, push piers and helical piers have their strengths. GridLock certified foundation repair pros will still often utilize push piers for chimneys, settling foundations with tight workspaces, and basements. Helical screw piles are ideal for new construction on poor soils.
