There can be many indications of settlement in a home:
• cracks in drywall above windows or doors or in the ceiling
• doors or windows that are difficult to open
• uneven or buckled basement floors
Foundation settlement can occur when the soil under the footing compresses leaving the footing unsupported. Gravity pulls at the footing causing the foundation to crack and the house to settle. Once the settlement has occurred, the house can start to experience differential movement and shifting that coincides with fluctuating moisture levels.
In many cases, the answer to a settled foundation is underpinning. Underpinning is the process of adding the strength and stability back to the foundation by adding support under the footing. Based on an engineered plan, we install helical piers (also known as screw piles) down to load bearing stratum (soils) at specified locations. Brackets are then installed under the footing to transfer the weight of the structure onto the piles. Based on the engineered plan, we can either lift or stabilize the structure. At LETY Construction, we install Grip-Tite helical piers. Our foremen are factory-trained, certified installers of all Grip-Tite products and are on-site throughout installation process.
