Helical Piers Foundation Repair: A Guide to Stabilizing Your Home

Helical Piers: A Reliable Solution for Foundation Stability

By Walsh Crawl Space | Published on November 19, 2024


Helical piers, also known as screw piles, provide an effective and long-lasting solution for stabilizing foundations and preventing structural damage. This guide explores how helical piers work, their benefits, and why they’re ideal for homes experiencing settlement or uneven foundations.

What Are Helical Piers?

Helical piers are steel foundation supports that are screwed into the ground to stabilize or lift foundations affected by soil movement or settlement. They consist of a shaft with helical plates, which allow the pier to anchor deeply into stable soil layers. By redistributing the load of the structure, helical piers provide lasting support for foundations, preventing further movement and damage.

Why Your Home May Need Helical Piers

If your home exhibits signs of foundation settlement—such as cracks in walls, sticking doors, or uneven floors—helical piers might be the ideal solution. These piers are designed to counteract poor soil conditions that can no longer support the weight of the structure. Whether your home is built on expansive clay, poorly compacted fill, or in areas with high water tables, helical piers can offer the stabilization and lifting required to restore the foundation’s integrity.

How Helical Piers Work

The installation process involves driving the piers into the ground until they reach stable soil strata or bedrock. The helical plates on the shaft ensure a secure hold, allowing the piers to transfer the building’s weight to more reliable soil. Helical piers are a minimally invasive solution and can be installed in limited access areas, making them versatile and efficient for various foundation repair projects.

1. Site Assessment

Foundation experts begin by evaluating the soil conditions and identifying the areas requiring reinforcement. This step ensures the appropriate placement and number of helical piers for optimal stabilization.

2. Pier Installation

Using hydraulic equipment, the helical piers are screwed into the ground to the required depth, bypassing weak or unstable soil layers. Each pier’s torque is monitored to confirm adequate load-bearing capacity.

3. Bracket Attachment

Once the piers are in place, brackets are attached to the foundation to secure it to the piers. This connection ensures even weight distribution and prevents further settlement.

4. Lifting and Stabilization

The final step involves lifting the foundation, if necessary, to its original position. The home is then permanently stabilized, protecting it from future settlement issues.

Perimeter Drain Systems: Essential Guide to Protecting Your Home from Water Damage

Perimeter Drain Systems: Essential Guide to Protecting Your Home from Water Damage

By Walsh Crawl Space | Published on November 7, 2024


Perimeter drain systems play a critical role in preventing water intrusion and managing moisture around your home’s foundation. This guide explains what a perimeter drain system is, how it works, and why it’s essential for any property owner concerned about foundation and water-related damage.

What is a Perimeter Drain System?

A perimeter drain system, also known as a French drain or foundation drain, is designed to channel groundwater away from your home’s foundation. By redirecting water away from vulnerable areas, these systems protect basements and crawl spaces from water infiltration, which can lead to structural damage and mold growth. A well-installed perimeter drain system collects water around the perimeter of the building and directs it to a sump pump or a safe drainage location.

Why Your Home Needs a Perimeter Drain System

Without proper drainage, water can accumulate around the foundation, leading to cracks, leaks, and compromised structural integrity. Perimeter drains help mitigate these risks by keeping water away from the foundation walls. They are particularly crucial for homes built in areas with high water tables or heavy rainfall. In addition to structural benefits, perimeter drain systems can help maintain a dry, healthy environment within crawl spaces and basements, reducing the risk of mold, mildew, and pests.

How Does a Perimeter Drain System Work?

Perimeter drain systems are typically installed at the base of the foundation. A trench is dug around the foundation walls, where a perforated drain pipe is placed and surrounded by gravel. This setup allows water to seep into the pipe through perforations, directing it away from the foundation. Some systems lead to a sump pump basin, where the water is then pumped away from the home. The gravel acts as a filter, preventing soil from clogging the pipe while allowing water to flow freely.

1. Trench Excavation

In the first step, professionals dig a trench around the foundation. The depth of this trench is carefully calculated based on the home’s foundation level and the local water table.

2. Laying the Drain Pipe

A perforated pipe is then laid in the trench, sloping slightly to ensure water flows in the right direction. The pipe is positioned to collect groundwater efficiently while avoiding areas that could lead to clogging.

3. Backfilling with Gravel

After placing the pipe, contractors fill the trench with gravel to support drainage while filtering out soil particles. The gravel layer is essential to maintain clear pathways for water to enter the drainage system.

4. Connecting to a Sump Pump

In many installations, perimeter drain systems are connected to a sump pump, which actively moves water away from the home’s foundation. The sump pump acts as a secondary line of defense against water intrusion.

Can a perimeter drain system prevent basement flooding?

Yes, a properly installed perimeter drain system is effective in preventing basement flooding by redirecting groundwater away from your home’s foundation.

Is a perimeter drain system suitable for all homes?

Most homes benefit from perimeter drains, especially if they have basements or are located in areas prone to heavy rainfall or high water tables. However, installation should be customized based on the property’s specific needs.
