| Case Studies
|
|
Date: April 2010
Structure: Residential home, Lansing MI
Contractor: Ayers Basement Systems
Engineer: Hayman Residential Engineering and City of Lansing
Material Used: Fortress Pre-Cured Pre-Preg Grid Mesh
Project Scope:
Scope of project is to cost effectively install a new reinforced foundation in front of the existing old foundation which is crumbling due to deterioration of mortar and block themselves.

Before
|
Solution:
Design was based on shotcrete pool design, combined with a cantilever load of building. In short design used current foundation as backfill for new foundation. The floor was removed for interior system. Spread footer was increased to accept new wall. 4'X 8' sections of Fortress Carbon Grid were hung off of new sill plate. Drainage board was installed against old foundation. (becoming sandwiched between old and new foundation). Then a 6" shotcrete wall was shot creating a brand new basement interior. Total job completed in 5 days.

Date: June, 2004
Structure: Family Residence, Benton AR
Contractor: Powerlift Systems
Engineer: Akii Engineering
Material Used: Fortress Carbon Fiber 4" grid straps in Fortress Epoxy matrix.
Project Scope:
Single story home on crawl space foundation had experienced fairly severe settlement. As a result of settlement, lateral loads were causing walls to buckle outward.
Solution:
After piers were installed and foundation lifted to near original level, Fortress Carbon Fiber was used to tie foundation back together.
Observations:
Fortress Carbon Kevlar Grid was installed in one day, allowing foundation to be re-parged coated for aesthetics the next day.

Date: July 2006
Structure: Family Residencial Property

Material Used: Fortress Carbon Fiber Kevlar Products.
Project Scope:

Block-Wall Reinforcement With
Carbon-Fiber/Kevlar-Grid ...
from our portfolio of Recent Projects
Our Recent-Projects Include New Construction
As-Well-As Addition and Renovation of House, Commercial, Condo,
Light-Industrial, Multi-Family Buildings, ...
The East wall of the Garage is an
exterior wall and the ground slopes on the outside towards south by
some eight feet.
The wall footing is pretty much at grade
level, and the ladder cracks in the wall indicate that the wall is
settling towards the South.
The East and the South walls are
both unreinforced block masonry and retain soil pressure from
backfill for the Garage floor on the inside.
I needed to
reinforce the walls, and I chose the practical method of reinforcing
the wall from the outside with NSM(Near-Surface-Mount)
Carbon-Fiber/Kevlar-Grid tape from Fortress Stabilization.
Here we are looking at the removal of wood waler of
the failed tie-back system -- Mr Johnson of Argon Construction is
hard at work grinding and cutting off the steel bolts ... Picture 1

In this picture we are looking from a little further back at the
Garage wall -- Mr Johnson is grinding off the bolts hoding the waler
of the failed tie-back system, Justin, also of Argon Construction is
looking for a metal blade, while Jack Tarry, of Andrews Renovation
Co, Project-Manager for the job is providing moral support ...

This is at the South-East corner of the Garage wall -- this is where
I opted to go in for drilled-piers diagonally across the corner of
the wall footing under which I want to insert a needle beam that
would rest on the drilled piers to stabilize the wall footing at the
corner ... Picture 3

Use of corner grid strap kit to stabilize foundation wall.
|
| Case Studies
|
|
Date: April 2008
Structure: Two story family residence / foreclosure purchase
Contractor: Expert Basement Repair, Cleveland, Ohio
Material Used: Fortress 4" corner grid strap kit in Fortress toughened epoxy matrix
Project Scope:
14 course high un-reinforced 12" cement block basement wall failure. The corner of the inside basement/garage wall had broken and pulled away.
Other cracking was evident but the corner repair was urgent.
Solution:
The vertical corner crack was injected with Fortress toughened epoxy and allowed to set up. A Fortress "corner stabilization kit" was then installed with 2' spacing between the four grids. Because the walls had not yet been painted, installation took only a few hours.
Observations:
With the critical corner now stabilized, the customer will have the remainder of his basement walls stabilized with Fortress 4" grid straps in the future as his budget allows.

Home Foundation Repairs
Use of Fortress Carbon Kevlar straps to repair shear slide and bowing of foundation wall.
|
| Case Studies
|

Date: March 2009
Structure: CMU foundation wall
Location: Marion, Ohio
Contractor: AquaGuard, LLC
Project Scope:
35 ft. CMU foundation wall: experiencing 1.5 inch shear slide at bottom of wall with a slight .75 inch bow and water leakage.
Repair method
To reattach shear slide, 3 inch core holes were drilled through second course of blocks down and 12-18 inch sections of rebar were inserted. Then core holes and bottom course of blocks were filled in flush with wall.
9 Fortress Carbon Kevlar straps were then applied to wall. Interior drainage system was installed and the entire basement was painted to make for a very happy customer!!

Pool Repairs
Fortress Countersunk Staples were installed in 1 day and will increase longevity of epoxy crack injections.
|
| Case Studies
|
|
Date: October 2009
Location: Baltimore, Maryland
Contractor: Levelift Systems
Engineer: Phil Shied, P.E.
Material Used: : Fortress Countersunk Staples along with Epoxy injections
Project Scope:
Many underground concrete pools suffer from cracking, movement and lack of reinforcement. As water leaks out of cracks it also increases the hydrostatic pressure. Many pools must be repaired on an annual basis.
|
Solution:
Countersunk staples add strength to epoxy injections of cracks, while leaving flush surface for pool refinishing and tiling.
Observations:
Fortress Countersunk Staples were installed in 1 day and will increase longevity of epoxy crack injections.

Shear Slide
Contractor utilized shear pins to secure wall to bottom courses of blocks and arrest shear slide.
|
| Case Studies
|
|
Date: December 2009
Structure: Residential CMU Block Foundation
Contractor: Expert Basement Repair, Cleveland OH
Material Used: Fortress Carbon Kevlar Grid Straps and 5/8" re-rod shear pins.
Project Scope:
Foundation wall had previous Tie Back Repair. Because of continued bowing and load of soil, a shear slide at the second course of blocks from bottom occurred.
Solution:
Contractor utilized shear pins to secure wall to bottom courses of blocks and arrest shear slide.
 |
 |
 |
5/8" X 1 ft re-rod we placed in 3" wide core openings, then grouted full with engineered grout mix also leveling bottom course of blocks to second course.
|
 |
 | |
Carbon fiber strap could now be installed to address bowing of foundation wall. In this case the carbon fiber straps are applied to second course of blocks unlike normal application which is to the bottom course.

Kevlar Necktie Anchor System
Top of poured concrete wall was sliding inward.
|
| Case Studies
|
|
Date: June 2009
Location: Cleveland OH
Contractor: Expert Basement Repair
Material Used: Kevlar Necktie top wall Anchor System
Project Scope:
Top of poured concrete wall was sliding inward due to lack of proper sill plate connection. Previous methods were very intrusive. Typically steel I beams or steel angle iron would have been used. The Neckties can be easily hidden by insulation in between the joists at the rim board.
Non-weight bearing wall...thus the joists running parallel with the wall. Several obstacles to work around. Drill holes and a long extension were used to install neckties to rim board.
Conclusion:
Six Kevlar Neckties can be installed in less than 1 hour with no obstructions this unit with tight area did take 1 day. The Neckties have a pullout from the rim board of 6,000 psi and the load is distributed in between joists.

Pool Repair
Residential Pool w/welded wire, shotcrete and pebblecrete finish
|
| Case Studies
|
|
Date: February 2010
Location: Atlanta, GA
Structure: Residential Pool w/welded wire, shotcrete and pebblecrete finish
Contractor: Murrell's Waterproofing and Construction
Material Used: Carbon Fiber Net w/#4550 Epoxy Resin
Project Scope:
Residential Pool experiencing leakage, both loss of water and infiltration of ground water into pool. Cracks were found in shotcrete and penetrating through the pebblecrete finish.
Repair Method:
Pebblecrete was removed, cracks were injected with epoxy resin. The Carbon Fiber Net was pre cut and laid into saturate, it was then placed in pool area and cured in place. This provided a structural cage at 0°, 90° and 45° layout. The Pebblecrete was then reapplied.
Conclusion:
Fortress Carbon net at 12,000 tensile per sq ft provided the added tensile needed which coating alone was lacking. Installation of Carbon Netting took approx 3 hours.
