What Is A Control Joint In The Concrete Wall?
A concrete expansion joint, also known as a control joint, is a gap in the concrete that allows it to expand and contract as the temperature changes.
It creates a barrier between the concrete and the rest of the building, allowing for movement without producing stress, which can lead to cracking.
They should be utilized in big concrete slabs like foundations and driveways.
All concrete shrinks somewhat as it cures and, once set, expands or contracts depending on the temperature.
Concrete expansion joints should be added to allow for movement in slabs with a surface area of more than 6m2 to avoid cracks from developing.
Concrete expansion joints are especially necessary where there have been successive concrete pours. They are also beneficial when putting concrete inside an area surrounded by walls or buildings or when incorporating things such as manhole covers.
If multiple construction joints are required, it is best if they are planned and specified by a structural engineer.
What Is Board Form Concrete Wall?
Board-form walls are finished with wood grain on the visible area of a wall and are built by putting forms onto setting concrete. Like a Sandscape finish or form finish, the board form finish changes the surface.
Typically, wood-textured forms are custom-ordered to match the intended aesthetic of the project. A board-form finish is feasible regardless of the size or shape of the wall. The front and sides of this water feature basin were built using board form walls.
There are a few things to consider regarding board form possibilities when determining which style of decorative wall you want for your project.
Of begin, because of the adaptability and customizability of these walls, there will be many elements to agree on. Second, depending on the personalized details, the price of these walls might rise by 20%. Finally, this finish works best on newly constructed walls rather than preexisting ones.
Why Can’t I Drill Into My Concrete Wall?
Drilling into concrete is challenging due to the density, hardness, and embedded aggregate stones that might obstruct the drill bit.
Drilling rapidly dulls drill bits. When the bit comes into contact with aggregate, it drags much more. A hammer drill is the best instrument for drilling into concrete.
A hammer drill is not the same as a rotary drill. The hammer drill, like a rotary drill, revolves. It hammers while rotating, unlike a rotary drill. Hammering aids in the pulverization of the concrete, while rotating produces the hole.
If you plan on drilling a lot of holes in concrete, a hammer drill can be a good investment. There are corded and cordless hammer drills available. The majority of hammer drills include two modes: concurrent hammer/drill mode and drill-only mode.
