Lindsley Waterproofing is proud to offer a wide range of helical piers for repair and new construction to residential and small commercial structures in North Carolina, South Carolina, Georgia and Tennessee.
Instant Foundations for Homes & Commercial Structures
New construction foundations don’t have to be a headache. The Helical Pier Foundation System gives you the performance of concrete without the drawbacks and liabilities of driven piles and drilled shafts.
The helical pier foundation can be devised to resist or support any load or application. And it’s fast. It can be installed with lightweight construction equipment and loaded immediately. There’s no concrete curing time, and predefined capacities are predictable, putting you in control.
Helical piers, also known as anchors, piles or screw piles, are deep foundation solutions used to secure new or repair existing foundations. Due to their design and ease to install, they are most commonly used whenever soil conditions prevent standard foundation solutions. Instead of requiring large excavation work, they thread into the ground. This minimizes installation time, requires little soil disturbance, and most importantly transfers the weight of the structure to load bearing soil.
New Construction & Repairs
This is the perfect choice for a wide range of commercial, industrial, institutional and residential applications including new homes and high-rise structures to sound walls, communication towers and bridges.
Here are just a few applications:
New construction supporting foundation grade beams, column bases, compression, tension and concrete slabs
Repairing failed or old foundations using time-tested engineering solutions
Retrofit foundations in existing structures where new loads are being added or under existing concrete slab
Permanent battered piers to take lateral loads, including wind and seismic
Machinery/equipment foundations for immediate loading with increased capacity
Wind and seismic loading applications such as sound walls, billboards, communication towers, etc
Foundation support in tight access or inaccessible areas, primarily vertical axial compression loading
Permanent or temporary foundation structural shoring, primarily vertical compression loading
Permanent tension hold downs for wind and seismic loads
Foundations in noise-sensitive areas where vibration is a concern
How it Works
A helical pier foundation system is a series of
segmented poles with helical bearing plates
welded to a central shaft that are drilled into
the ground. The load is transferred from the
shaft to the soil through these bearing plates.
As a result of their true helical shape, the helices
do not auger into the soil but rather screw into
it with minimal disturbance.
The first section, called the Lead Shaft, contains
the helical plates. The Lead Shaft can consist of one to four helices. If required, additional helices can be added with the use of Helical Extensions and will be based on the depth needed. Plain Extensions are then added until the Lead Section penetrates the bearing strata and the necessary or appropriate torque is achieved.
The Helical Pier Advantage
The helical pier foundation, in many situations is preferred over driven piles, drilled shafts, grouted tendons, auger-cast piles, belled piers and other deep foundation systems for a number of reasons, including:
Fast Installation and Immediate Loading
It's a Pre-Engineered System
There's Instant Torque-to-Capacity Feedback for Production Control
There's No Need for Concrete to Cure
It Minimizes Soil Disturbance During Installation
It Installs in Any Weather
There's No Vibration
It's Environmentally Friendly
