What Is A Concrete Strip Foundation?

Strip foundations are a type of foundation that transmits weight from structures to layers of soil or rock with adequate bearing capacity and settling characteristics. Foundations can be classified as shallow or deep. When the weight of a structure is smaller than the soil’s supporting capability, shallow foundations are often recommended.

When the surface soil cannot support the load of a structure, deep foundations must be built. A deep foundation transmits loads from the surface to deeper strata capable of bearing the weight.

Strip foundations are one of the most popular foundation types. They are often applied to soils where the subsoil has a high bearing capacity.

Strip foundations are intended for structures with relatively moderate loads, such as low-to-medium rise dwelling buildings. Strip foundations are permitted in the traditional style of most home building.

Strip foundations are made out of a continuous strip of concrete that is built centrally under load-bearing walls. The continuous strip serves as a support for which walls are created and is of sufficient width to equally distribute the load of the structure on the ground underneath it, thereby sustaining it.

This is referred to as a “uniformly distributed load” (UDL), and it relates to the even transfer of a structure’s loading at the foundation level onto subsoil capable of carrying the load without undue compaction.

What Is A Floating Concrete Slab Foundation?

Floating slabs are concrete slabs that are laid over the ground with no anchoring, as though it simply rests and floats over it. As the name implies, a floating slab resembles a plate that is simply put over water with no connection between them.

The primary usage of floating slabs is as a foundation for sheds, manufacturing workplaces, house additions, or garages. It is cost-effective when utilized in regions where normal foundations are not required.

Plumbing and electrical lines are often attached to the slab in a normal floating foundation by simply passing them through the floor as it is poured. This implies that the plumbing, drainage, and electrical lines must all be finished before the foundation is poured.

It is often a considerably less expensive technique of construction than utilizing a footing-fitted foundation, but it can result in very high maintenance bills if the plumbing requires repairs in the future.

In warmer areas, the floating slab is substantially more user-friendly since it does not bend as much due to fewer dramatic temperature variations. It also aids in cooling the structure since the contact of the foundation with the earth pulls cold temperatures through the concrete and disperses them throughout the structure.

How Do You Screw Into Concrete Foundation?

The majority of pipes, gas lines, water lines, and other inserts that must go through a concrete foundation are drilled for by the contractor during the home’s construction.

However, you may discover that you need to add more as time goes on to accommodate more wires or pipes. Although anybody can cut through concrete, the amount of difficulty relies entirely on the size of the hole, as equipment vary according to this diameter. Here are some methods for drilling holes in concrete foundations:

Drill Bits

Small holes with a diameter of about 1/2 inch are drilled straight into the concrete. There are many different types of drill bits designed for work with concrete, but the most important thing is to be sure you use a good bit.

Aside from personal choice, the difference between bits is insignificant. You don’t want to attempt to match up a hole on the exterior with a hole on the inside, so acquire a bit that’s long enough to go all the way through the concrete foundation.

Drill With A Hammer

When working with standard drill bits, a hammer drill is the ideal tool to use. Although a standard drill can perform the job, a hammer drill adds vibration to the bit’s spinning action.

This extra vibration serves to break up the concrete, allowing the bit to penetrate more easily and with less stress on the bit and drill. Most hammer drill types allow you to control the intensity of vibration to the bit.

The Core Bit

Anything greater than 1/2 inch necessitates the use of a core drill and bit rather than a standard drill bit and hammer drill. These are specialized drills with a stand or tripod that aids in keeping the drill stable during the drilling operation.

The drill bit cores into the foundation just around the circumference of the bit, leaving a cylindrical block of concrete inside the core bit.

This chunk is either removed after drilling or broken up on a regular basis to maintain the bit running smoothly. There are dry and wet variants available, but a wet-core bit should never be used inside a house.
