About Retaining Wall Blocks

Introduction

Retaining Wall Blocks Block retaining walls are commonly referred to as: segmental or modular block retaining walls. They consist of interlocking concrete blocks or units are used for projects which require support and structural resistance. These systems are generally pre-engineered. They offer and attractive and stunning appearance whilst they are affordable, economical and highly durable. They are also versatile which makes them suitable for all types of applications.

This type of retaining wall is generally built with the following types of block units: interlocking concrete blocks, precast concrete blocks or offset stacking blocks. All of the block retaining wall materials are highly independent and they rely on their own weight to support the entire wall. Backfill or anchoring systems should always be used to construct a block retaining wall for extra support.

Block Retaining Wall Systems

A block retaining wall system is generally comprised of several different elements which help the wall to be structurally supportive. These elements in the system include the following:

  • High strength concrete blocks.
  • Foundation soil for superior quality.
  • Leveling pads.
  • Concrete reinforcement pins if the blocks are not interlocking.
  • Geo-textile soil reinforcement.
  • Drainage fills.
  • Wire
  • Anchors if the wall is relatively high.

Each component plays a vital role in the construction and support of the entire block retaining wall. These components of the system can be purchased as a complete and specified kit or separately depending on the application size.

The Benefits of Building a Block Retaining Wall

Block Retaining Wall These retaining walls are very beneficial applications for properties which are sloped or damaged due to erosion. They are also great to support and surrounding landscaped gardens of larger sizes. These walls will control erosion by creating a barrier for the exposed soil. They will tame a sloped land site immensely and help make the property be more useful. Block retaining walls are highly beneficial for landscaped gardens because they offer protection for all the flowers and plants included in the landscaping. They can also help keep soil and debris off driveways when built around them. These retaining walls can also be built to help slope patio areas.

Drainage

A block retaining wall should always feature a good drainage system to ensure that water can easily travel through and exit the wall. If water happens to get caught inside the wall then it can cause server damage internally and create loads of moisture in the walls materials. This can result in cracking and chipping of the wall. Eventually the water will build up and create pressure for the wall and it could cave in. drainage kits are well designed and highly beneficial for a block retaining wall.

Backfill

Backfilling Backfill is used on all types of retaining walls to offer it extra support and to keep the wall stabilized. Backfill materials suitable for block retaining walls include: crushed stone or gravel, cement, sand and cement bond. Some larger block retaining walls will require concrete reinforcement pins or wiring to further stabilize the large wall.
