Cracks Yes I understand what you are saying spunky eml, bonding with a mesh bedded in then skim coat. What Iwas saying was to stop the cracks reapearing I didnt kow if I had to remove all the plaster back to the blocks then put plaster board ontop of the blocks and a finishing skim to solve the problem.

1. I understand that thermalite can shrink and crack as the blocks were saturated when laid. Question is what is the correct procedure now? There are three hairline cracks running the entire height of the wall from damp-course to the leaded top of the wall, nothing below the damp-course which is concrete block.
2. Using Thermalite blocks in the inner leaf of the cavity wall can meet U-values down to 0.17 W/m2K with a 300mm footprint. If Thermalite Enhanced Construction Details are used, this will also dramatically reduce the heat loss through thermal bridging at the junctions of elements.

Imagine waking up at home, ready for a new day. You head into the bathroom to start getting ready – and there’s a crack above your doorway.

Do you panic? Not necessarily. New and old homes alike can fall victim to wall cracks. Concrete block walls, in particular, can form cracks for a number of reasons. Before you reach for the phone, take your time and inspect the crack you’ve spotted. Some cracks are just annoyances, while others are symptoms of a larger problem – and with a little bit of know-how, you can tell the difference.

Finding Cracks Indoors Versus Finding Cracks Outdoors

The cracks in your walls form for a reason. That said, interior wall cracks often have different causes than exterior wall cracks. Interior cracks in concrete block walls can form for a number of reasons, including:

• Long-term home vacancies
• Faulty piping
• Leaks
• Structural problems

The walls on the outside of your home can crack for many of the same reasons. However, if you notice your exterior walls cracking, you may be dealing with:

• Excess home weight
• Settling
• Excess moisture
• Rapidly changing weather
• Inadequate drywall installation

The good news is that not all wall cracks are worth panicking over. If you notice that your cracked wall is leaning or letting in water, then you’re going to want to reach out to a Denver, CO, contractor. If the crack is simply an aesthetic nuisance, you can cover it yourself without worrying about the structure of your home.

Types of Concrete Cracks

Concrete block walls can fall victim to a number of different types of cracks. These types include:

• Vertical – Vertical cracks in your concrete block tend to appear as your concrete cures. The process will bring the particles closer together and create cracks that are often too small to cause any problems. However, if your exterior waterproofing isn’t enough to cover these cracks, you could soon find yourself dealing with a leak. To prevent vertical cracks from forming, be sure to use a liberal amount of concrete during the pouring process to better account for shrinkage during the curing stage.
• Horizontal – If the supports in your walls aren’t strong enough to hold up to the weight of concrete, you may notice your walls starting to bow. In these cases, you’ll likely also see horizontal cracks start to develop. These cracks are a sign of stress, and if they continue to grow, you’re going to want to seek out the help of a contractor to determine what support solutions are available to you.
• Diagonal – Diagonal cracks can form for the same reasons vertical cracks do. If you notice a diagonal crack in addition to wall bowing, you likely have split supports in your walls. If a diagonal crack appears near a door or window, you can blame it on concrete shrinkage, as with vertical cracks. However, if you have a diagonal crack that’s wide toward the top and slim toward the bottom, then your foundation may be settling. These cracks can let in water, but they’re not a sign of faulty supports. Instead, your foundation may be expanding and retracting in response to the weather. The crack will be a result of that rapid change.
• Stair-Step – Concrete block walls often crack along their block lines. If you notice a stair-step crack, think of it in the same terms you would a diagonal crack.

Concrete Block Cracks: What to Do

In most cases, you won’t have to worry about the minor cracks that appear in your concrete block wall. If you notice a crack accompanied by infestation, leaks or mold, however, you’re going to want to have your wall assessed for structural deficits. Know that it's always best to take preventative measures.

If you notice vertical or diagonal cracks forming, have a contractor inspect your foundation, as you may have a foundational leak on your hands in addition to any leaks the wall crack has caused. The waterproofing process can also help protect any green wood supports from coming in contact with water and weakening further.

That said, don’t rely on the waterproofing process as a quick fix. If you think your walls are bowing over a crack, reach out to a professional as soon as possible. Local contractors in Denver, CO, will be able to let you know what’s going on with your wall and what potential solutions will help you retain the value of your home.

Repairing Cracks In Thermalite Blocks Sizes Blocks

Crack repair products strengthen cracked masonry walls by enhancing the tensile, flexural and shear strength of brickwork using various brick rein­­for­­cement techniques. Sealing fissures with appropriate fillers help to restore compressive strength and protect against water infiltration and frost damage.

Cracks are usually the result of the structural movement of part of a building. The displacement may be historic, cyclic or on-going. Predictably, a masonry structure can move when it exposed to the effects of variations in temperature, chemical reactions, age deteri­­ora­­tion, vibration or changes in the moisture content of brickwork, or the ground that supports it. Once a wall fractures, it is no longer a composite structural unit.

Typical defects that may trigger cracks include any one or a combination of:

• Ground movement – Subsidence, land slip or heave
• Inadequate support – Localised foundation failure, lintel failure, masonry arch failure, etc.
• Insufficient restraint – Lack of wall ties, restraint straps, poor bonding, etc.
• Resizing – Expansion or shrinkage due to thermal or moisture variations
• Rusting metals – Wall tie corrosion, expansion of hoop irons or fixings, etc.

Identifying and eliminating the cause of the fracturing is essential in ensuring the lasting success of a masonry repair scheme.

Generally crack repair strategies fall into one of two categories:

• Sub-structure repairs for below ground foundation movement issues, typically an insured risk
• Supers­truc­ture rein­for­cement for above ground building defects, typically an uninsured risk

Sub-structure repairs may include underpinning or piling.

Supers­truc­ture rein­for­cement generally includes structural repairs accomplished by the insertion of helical bars that form retrofitted brick beams or crack stitching systems Replacement wall ties and restraints tie cavity walls or separating façades, whilst resin injection products efficiently fill and seal cracks in walls

After resolving the source of faults or weakness, fill the cracks and reinforce the zone of brickwork that has fractured to ensure once again it performs like an integrated structural unit.­ Crack repair techniques include mechanical brick stitching and crack injection resins, whilst various tie and strapping systems help to constrain further movement by transferring and sharing loads.
