Stitched Crack !!HOT!!

Cast iron only cracks when it is stressed beyond its tensile strength. This includes all heat related cracks, freeze cracks, impact and bending loads. Cast iron does not weaken over time. It does change if exposed to high temperatures over long periods of time like exaust manifolds and wood burning stoves. The process is called graphitization. The carbon is changed to graphite and any type of welding that requires melting the cast iron becomes very dificult because the filler metal will not bond properly. Brazing is not affected because the iron is not melted during the process. Click here to learn more

Stitched Crack

AquaBond's new, patent-pending S-Stitch Concrete Crack and Fracture Repair System for swimming pools and decks is far more versatile and faster to install than other concrete repair staple or stitch systems. You'll save tons of time by grinding shallower and narrower channels than old-style steel staples require - and shallower invasion reduces microcracking. You can even double up, or criss-cross S-Stitches for amazing resistance to future movement!

S-Stitch staples are embedded into cracked concrete and encapsulated in anchoring epoxy. Spanning the crack or fracture, a series of them, installed per instructions, restores and even improves, the strength of the concrete.

Cross-stitching is a repair technique for longitudinal cracks which are in reasonably good condition. The purpose of cross-stitching is to maintain aggregate interlock and provide added reinforcement and strength. The tie bars used in cross-stitching prevent the crack from vertical and horizontal movement or widening.

Cross-stitching uses deformed tie bars drilled across a crack at angles of 35 degrees. A number 6 bar is sufficient to hold the joint tightly closed and enhance aggregate interlock. The bars, spaced 20-30 in. from center to center, alternate from each side of the crack. Heavy truck traffic and airplane traffic require the 20 in. bar spacing. A 30 in. spacing is adequate for light traffic and interior highway lanes.

Do not stitch a transverse crack which has assumed the role of an adjacent joint. Stitching will not allow transverse joint movement (open and closure). A new crack will likely develop near a stitched working crack or the concrete will spall over the reinforcing bars.

The Stitch-Tie Bar is used to repair cracked masonry and can provide reinforcement to create structural beams from existing brick veneers. The bars are manufactured of Type 304 stainless steel (Type 316 available upon request). The Stitch-Tie Bar and SureGrout provide excellent bonding characteristics within the masonry. When used together, Stitch-Tie Bar offer a superb combination of axial strength and flexibility, which helps absorb further localized stress. They are installed in existing mortar bed joints that have had mortar removed to accommodate the bar and grout material.

Masonry may move and crack as a result of movement in foundation soils, seismic activity and cyclical wet and dry, hot and cold environmental conditions. Crack stitching reintroduces structural integrity and redistributes structural loads for a quick, simple, effective and permanent solution.

1. Using an appropriate power cutting tool, rake out or cut slots into the horizontal mortar beds, to a minimum of 500mm either side of the crack, to the specified depth (typically 25-35mm) and at the specified vertical spacing (typically not more than four brick courses or 340mm apart).

When tying cracks in face brickwork these high strength bars are grouted into slots cut into mortar beds, ensuring the reinforcement is discreetly concealed once the mortar joint is pointed. Tensile forces are redistributed along the wall to dissipate load and minimise the risk of further cracking.

When repairing fractures in rendered walls the reinforcing bars can be installed directly into the brick units to bind them together and, where shear strength is an issue, to permit the use of diagonal reinforcement. Stitching offers a quick, easy and reliable method of restoring the structural integrity of cracked walls at cost effective prices.

As a market leader in the supply of the best retrofit reinforcement products in the UK, Twistfix are able to offer technical advice on crack stitching techniques that repair cracks permanently, irrespective of whether they are built from brick, block or stone. Simply call our help line to speak to a masonry crack repair expert.

The stitching tie is pressed into the mortar (right), followed by a troweling of the FX263 mortar to fill the joint. By virtue of the continuous deep-helix channels, the bar forms a bond within the grout to strap the brickwork on both sides of the crack. The repair is inconspicuous and preserves the appearance of the structure.

Pool Grid Stitches are the latest innovation in concrete crack repair - designed to add value and strength to repairs by distributing load beyond the glue line. The stitches in this kit are comprised of high tensile strength carbon fiber and molded into a unique grid-like, woven formation. This grid design allows for the staple epoxy to move through the stitch, providing a superior bond with the epoxy. The stitches install perpendicularly into just a single saw cut, eliminating the need to chisel away material from the staple bed and drill extra holes. The typical stitch is 10" long by 3/4" wide. They can also be cut for more flexibility in installation options. Stitch spacing should be every 8" - 12".

The Rhino Concrete Crack Lock (CCL) is a revolutionary new product that was developed to improve concrete crack repair. The CCL is installed by making a single blade-width cut across the crack and drilling two holes along the cut at the appropriate locations. Once the preparation is complete and free of dust, it is filled with an approved ARDEX Epoxy Paste such as ARDEX RA 88 (for vertical applications) or ARDEX RA 142, ARDEX RA 144 or ARDEX RA 146 (for horizontal applications) and the CCL is inserted. Once installed, the CCL permanently bonds both sides of the crack together. Due to the unique shape of the CCL and the preparation in the concrete, the tensile strength of the carbon fibre is relied upon as well as the epoxy bond strength along its length.

At The Dimensional Group we have a number of vinyl products that could be affected. From binders to checkbook covers and more, we do our best to make sure they arrive to your doorstep looking as fresh and brand new as you expect it to. We know cold crack exists, and now you do too.

However, before remedial works are undertaken it is important to understand what causes brickwork/masonry to crack. There are many causes of cracking to brickwork/masonry and we will look at some of them below.

The cracks with this form of movement generally increase in width the higher the cracks rises. Where subsidence is associated with clay soil then the volume of the clay changes with moisture content changes ( ie seasonal changes) and so the crack may open and close dependant on the moisture content of the clay substrate. This movement is called cyclical movement.

Generally, cracks in brickwork that have been classified as passive or historic or that are due to cyclical movement, can be reinforced by crack stitching methods that will improve both the tensile and flexural strengths of the brickwork panel.

Stainless steel helical reinforcement bars are bonded into the mortar joints with strong grout or resin stretching either side of the crack and at vertical intervals of between 300mm and 450mm. This then ties the brickwork/masonry on either side of the crack.

Mortar joints are raked out using a special grinding tool to 500mm on each side of the crack. The joints are then thoroughly wetted to remove dust and debris and the specialist fixing grout is installed into the raked out joint using an applicator gun.

Where the cracks extend around the corner of the building then this system of crack stitching can be extended around the corner of the brickwork thus substantially reinforcing the corner brickwork as well as the brickwork on either side of the crack.

If you have noticed cracking in your concrete foundation, basement walls, or driveway, concrete stitching may be the best way to repair these issues. At Rock Structure Repair we will use our more than 17 years of experience and expertise in the industry to derive the best solution to repair your concrete cracks. Concrete stitching is applicable for a number of situations where strengthening joints or cracks are required. There are two types of concrete stitching: the first is cross stitching and the second is slot stitching. Each is beneficial in its own way. Cross stitching is the most common way of concrete stitching; its deformed tie bars are epoxied or grouted into holes that are drilled at an angle through the crack. Slot stitching also uses deformed tie bars grouted into slots cut across a joint.

Patented helical Crackstitching Bars for masonry repairs to walls and brickwork. These twisted crack stitching bars comprise 6mm high tensile (circa 8kN) stainless steel helical ties that are bonded across cracks in a wall to increase the tensile and flexural strength of masonry. The cracked wall is reconnected, tensile forces redistributed along the full length of the bars helix and the stabilised structure restored to full strength.
