Concrete Blocks


Concrete blocks are made in three different types, which includes solid, hollow and interlocking. Concrete blocks are typically classified into a category by their density or unit weight. Density is determined by the amount and type of aggregates added in the concrete mixture to produce lightweight, medium and normal weight concrete blocks. Concrete blocks are available in non-load bearing and load bearing types.

The load bearing blocks made from concrete offer more compressive strength than standard stone blocks. Reinforced steel bars and anchorage systems can enhance the ability of a concrete block wall especially for load bearing types.

Concrete blocks are a versatile masonry material which can be used in a wide variety of applications. These blocks are produced in mass production lines by KCP which allow homeowners and contractors to purchase them immediately and have them delivered or picked up ready for installation. These blocks are available in many different sizes and designs. They can also be assembled in many different patterns. Concrete blocks are an inexpensive building material which can save homeowners hundreds in the pocket. They are a great alternative to natural stone blocks.

Applications


The load bearing blocks made from concrete offer more compressive strength than standard stone blocks. Reinforced steel bars and anchorage systems can enhance the ability of a concrete block wall especially for load bearing types.

Concrete blocks are versatile; they can be used for many different types of applications whether the application is load bearing, structural or decorative. Load bearing applications of concrete blocks can either be veneer which is supporting a roof or a retaining wall which is supporting a large amount of soil. This type of application may require reinforcement of the concrete blocks to ensure the material is further protected and able to withstand the weight that is required. The typical shape of a concrete block is rectangular or square. Our size in thickness ranges from 90mm to 230mm. They can also be customized to suit the design requirements of the project.

Here is a list of common concrete block applications:

Retaining Walls
Siding
Veneer
Homes
Commercial Properties
Steps
Landscaping Garden Beds
Curbing and Edging

Solid blocks

This type of block material is generally installed with a mortar. Before installation begins a solid foundation should be set to a depth according to the style and type of installation. As each course of concrete block is laid cement based mortar should be smoothened to the concrete block as it is applied. The mortar works by bonding each concrete block together and ensuring the structure is stable and well established as a singular unit. Mortar can be applied with a trowel. Different types of mortar are available so it may be wise to seek professional advice on the best mortar to suit the concrete block application.

Hollow blocks

Another installation method for concrete blocks is the dry stack method. Sometimes hollow blocks are used for this type of method. The blocks are laid course by course without a mortar. As a course is laid the finished course of blocks should be filled with a backfill material like crushed stone or gravel. The back fill helps the structure to become stable.

Interlocking blocks

Interlocking concrete blocks also do not use a mortar for installation. A typical interlock concrete block will have a lip or lug at the bottom of it. As each course is laid the blocks interlock with one another and create a strong and durable structure. The style and method of application will generally depend on the type of application. Building structures are always recommended to be installed by the mortar method. Garden and landscaping applications can use interlocking and dry stack methods.

Hollow-Max Span

Is a type of concrete block used for construction of suspended floor slab with advantages of:

  1. Reduced dead weight for the building thus reducing the cost
  2. Reduction of concrete volume
  3. Insulation improvement
  4. Sound improvement
