Secure Foundation Systems, Inc. utilizes a variety of “grout ready” underpins, helical piers and auger piers that can be custom tailored to your site specific plan.

Grouted Pressure Underpins (fig 1 at right) are essentially steel pressure underpins with grout holes or perforations cored out in a variety of shapes and sizes according to the application or engineers specifications. Grouted Pressure Underpins are generally installed at the bottom 8 to 16 feet of a pin location just above the top of competent rock layer to allow grout material to seal off the limestone bedrock. This process ensures that further rock erosion at the source of the ravel zone is halted and effectively remediated.

A custom bracket assembly system attaches to the top of the Grouted Pressure Underpin securely fastening it to the buildings foundation. All brackets installed by Secure Foundation Systems, Inc. are fully adjustable. Any vertical adjustment later required can be easily accomplished with no adverse impact on the property.

Grouted Helical Piers (fig 2 at right) consist of a round steel shaft with a series of welded plates that create a screw-like anchor. The shaft extensions are bolted together to allow sufficient torque drive for installation at pre-determined depth. Grouted Helical Piers are custom manufactured to achieve a compression capacity rated according to your Engineers’ design.

Grouted Helical Piers can be fabricated with single, double, triple and even quadruple helical plates to allow personalized customization of the site's specific demands.

Grouted Helical Piers are screwed down until certain soil bearing capacity is achieved, resistance lock is reached or required torque is attained. During installation torque resistance is monitored by the Geological Engineer and provides visual verification of when the helical anchor capacity is achieved. After installation is complete each helical pier is pressure grouted to consolidate the soils below the pier and strengthen the end bearing capacity.

Grouted Helical Piers are ideally utilized to support building foundations in areas with soft, weak, shallow or poorly compacted soils.

Grouted Auger Piers (fig 3 at right) are utilized when drilling is required to penetrate areas of dense and/or non-porous soils such as clay or “high blow count” layers. Grouted Auger Piers are always drilled or augered down to the top of the limestone or load bearing strata to ensure grout application at those depths. This process ensures that further rock erosion at the source of the ravel zone is halted and effectively remediated.

The grout holes in the Grouted Auger Piers are cored in a variety of shapes and sizes and can be custom designed according to the application or engineers requirements.

Grouted Auger Piers are utilized for compression (load bearing) applications.

For years our industry has required a two step process to properly remediate a “sinkhole” affected property. First by pressure grouting and consolidating soils, second by underpinning the structure and returning it to the it's original elevation.

By utilizing Secure Foundation Systems, Inc. Grouted Injection Pier System you can rest easy knowing your property repair cost will not exceed your proposed repair estimate.
