Belgard Pavers and Wall Block Retaining Walls are Now available in the Redding, Northern California Area.  Home owners, contractors and developers welcome. Belgard Celtik Retaining Walls are stackable, mortarless blocks available in many colors and styles for building concrete block Retaining Walls.
Whether your project involves adding terrace, raised planting beds or large structural retaining walls Belgard offers a solution for your design and aesthetic needs. Celtik Wall units are designed for use as retaining walls, terraces, planting beds, steps and any decorative application where a maintenance-free, easy-to-install building material is preferred. The Celtik Wall unique anchoring system is available for the construction of vertical or sloping walls. Celtik Wall units are made from specially designed and shaped modular concrete masonry units. Belgard concrete pavers and retaining walls will enhance the aesthetics and value of your property.
Segmental retaining walls consist of modular concrete blocks that interlock with each other. Segmental retaining walls can be installed in a wide variety of colors, sizes, and textures. Retaining walls can be constructed of many different materials and with a variety of building techniques.
In most states, retaining wall designs taller than about 4 feet must be designed by or approved by a qualified, licensed professional engineer. Ultimately, all retaining walls serve to hold back a vertical or near vertical face of soil that would, without adequate retention, cave, slump or slide to a more natural slope. Designing any retaining wall requires a knowledge of lateral earth pressure, the pressure developed by the backfill.
By understanding how a wall works, and how it can fail, it is possible to engineer a retaining structure that will meet all foreseen environmental, structural and construction demands.


Drainage of water as a result of rainfall or other wet conditions is very important to the stability of a retaining wall. Segmental retaining walls offer many advantages, including rapid construction, horizontal and vertical curvatures, easy grade changes, a wide variety of colors, and sizes and textures. When the weight of units alone is not enough to resist soil loads, horizontal layers of geosynthetics are used to reinforce soil behind walls.
Stately and majestic, Celtik retaining walls create outdoor living spaces that are beautiful to behold and inviting to walk through.
Just like the vertical aspects that it enhances, the retaining walls come alive by incorporating the roughness and irregularity of natural stone. The Celtik Wall evokes the texture and unevenness of natural stone and is ideal for creating curves or straight walls and pillars.
The Celtik Wall anchor pin facilitates the construction of walls with a maximum height of 42″ (1067 mm), in ideal sites. The facing systems usually consist of modular concrete blocks that interlock with each other and with the lateral restraining members.
This discussion will focus on segmental retaining walls as the structural material, but monolithically poured concrete walls, steel, timber, used tires, and reinforced soil are often used too. Additionally, it is important to check with and adhere to local building codes prior to any construction, even when walls are shorter than four feet. These factors include cost, required wall height, ease and speed of construction, ground water conditions and soil characteristics.
It is the force generated by the lateral earth pressure that constitutes a large part of the load that the wall must carry.
This includes checks for wall overturning, base sliding, and soil bearing capacity failures.
Hydrostatic pressure can cause or induce retaining wall failure, or at least damage the wall.


Without proper drainage the backfill can become saturated, which has the dual impact of increasing the pressure on the wall and lessening the resistance of the backfill material to sliding. Weepholes actually penetrate the retaining wall and drain the area immediately behind the wall. With proper soil reinforcement and design, segmental retaining walls can be constructed to heights in excess of 40 feet. A special pin system has been designed to stabilize the overall structure and guide the installation of the modules.
They are ideal for not only slope support, but also for widening areas that would otherwise be unusable due to the natural slope of the land.
Retaining walls are, and should always be viewed as load bearing members first, and aesthetic groundscapes second. Weepholes should have a minimum diameter so as to permit free drainage; for large walls, 4-inch weepholes are common. Belgard’s Celtik Wall applications are available in a range of colors to complement your home and grounds. With the unique construction of segmental retaining walls, higher and steeper walls can be constructed with the ability to retain the force of lateral earth pressure created by the backfill soil. Retaining walls are often used for grade changes, and for other functional reasons such as widening driveways, walkways, or creating more space in a patio outdoor area. Modules are delivered with 2 different anchor pins: a regular pin with blades, and a second pin without blades, designed for the construction of corners. Weepholes should always have some kind of filter material between the wall and the backfill to prevent fines migration, weephole clogging, and loss of backfill and caving.
