Vertical Prestressed and Precast Concrete Wall Panels
ACP Vertical Cantilever Concrete Walls Systems provide economic solutions for the construction of retaining walls to suit many different applications such as bulk storage bunkers, earth retaining walls, silage clamps, above/below ground tanks and bund walls. The panels are cast into a shallow foundation which provides the cantilever support for the wall.
There are 2 vertical concrete wall products to choose from:

About Our Cantilever Prestressed Precast Wall System
Installation
These high quality prestressed precast concrete wall panels are designed to be installed into a shallow trench foundation onto a simple concrete blinding at a depth of 0.5m and tied into the foundation concrete using cradles and reinforcing bars.
With the vertical wall panels temporarily propped in position, and the supplied reinforcing bars inserted through and underneath the panels, the foundation concrete is placed enabling each panel to be connected to the foundation to provide essential support.
This technique requires no site drilling or grouting (usual with L-shape installation) and no additional above ground supporting steelwork making them ideal for tanks, compost/silage bunkers and cellars.
Key Features
It provides a smooth wall on both sides with a perfect 90° wall to floor joint which, when used in a storage building / bunker, reduces the risk of any damage occurring between loading shovel and the wall, consequently reducing the risk of contamination and improving cleaning.
After installation the panel joints and wall/floor joint can be sealed to provide a watertight seal.
Each vertical prestressed wall panel features an interlocking ‘tongue and groove’ system. This joint ensures the panels fit neatly together and allows shock loads to be transferred between units, reducing the likelihood of damage. It also allows the panels to follow a moderate radius enabling the construction of concave and convex wall structures. This also allows flexibility in the foundation orientation, particularly beneficial in boundary wall constructions.
A MODERN ALTERNATIVE to traditional ‘L-Shapes’, this wall system is designed to provide a complete retaining wall solution, making it ideal for both above and below ground applications.
They are suitable for a diverse range of application including bulk commodity stores, waste stores, above and below ground tanks, biomass stores & silage clamps and earth retaining structures for car parks, goods yards and landscaping projects. This cost-effective walling solution offers fast installation whilst still providing a high quality, durable and robust prestressed wall.

Why Choose Prestressed Precast Concrete Walls?
There are many advantages of using a prestressed concrete wall panels over traditional construction methods:
?
To discover more about 'What is Prestressed Concrete?' visit our FAQs section
High Quality Off-site Production
Manufactured offsite in controlled factory environment conditions from high grade 60 N/mm²engineering grade concrete to recognised industry standards i.e Eurocode 2, BS8110, BS5502 Part 22.
This provides known performance specifications and very often no further engineering input is required. The wall panels are delivered to site already ‘made to measure’ for fast installation.
Fast Installation Without Compromising On Quality
Depending on size of the panels a construction team of 4 operatives can install up to 100m²/day.
Once the panels are propped safely in position with the reinforcing bars also the foundation concrete can be placed.
As soon as the foundation concrete has reached the required strength the props are removed and the wall is ready to be sealed.
Load Sharing Interlocking Joint
Each Prestressed Concrete Wall Panel is designed with an interlocking ‘tongue and groove’ joint system which keeps the panels in line during installation onsite but more importantly this positive connection allows the panels to ‘share’ the load along the wall.
This joint also enables the construction of concave and convex wall structures which is particularly beneficial in boundary wall constructions.
Space Efficient
The relatively thin section Vertical Cantilever prestressed precast concrete wall panels maximise the storage space available compared with in-situ concrete walls or moveable ‘lego’ blocks.
All our Vertical concrete wall panels are designed to create a perfect 90º wall to floor joint again maximising the storage space. This eliminates potential damage points between the loading shovel and the precast concrete wall commonly associated with traditional "L" and "T" section wall panels.
It also reduces the risk of contamination of the stored material entering the wall joints and is ideal for the rapid cleaning of individual bunkers between compost batches.
Double Loading
All our prestressed vertical cantilever walls are designed to be double loading which enable you to store materials on either or both sides.
Durable
Prestressed concrete is deceptively strong for its size. The durability of our prestressed precast concrete wall panels is enhanced by the interlocking ‘tongue and groove’ joint system which enables shock loads to be transferred between units, reducing the likelihood of damage from any vehicular impacts.
The smooth finish of our vertical prestressed precast concrete wall panels makes loading of any bulk storage structures quick and easy. The smooth face of each wall panel makes it easy to clean as there are no edges to be damaged or ledges for the product to stick to. The dense concrete also eliminates concerns about damp ingress or pest infestations within the walls.
Fire Resistant
Depending on the section size used up to 4 hour fire resistance is available with a vertical cantilever prestressed concrete panel wall. Joints should be sealed with intumescent sealant.
Product Sizes & Performance Specifications
Wide Range of Sizes & Performance Specifications
The prestressed wall panels are available in three standard thicknesses, to suit a wide range of anticipated loadings, and in a range of widths, the most commonly used being 1m, 1.2m and 1.5m. Heights are cast to your requirements.

Design Guidance and Maximum Height Tables
What Thickness/Type Do I Need To Use?
The panel type required for you application depends on a number of factors:
- The overall height of the wall.
- The type of product to be stored or retained against the wall and its bulk density & angle of repose.
- The profile of the stored material, will it be stored level with the top of the wall or will it be surcharged/heaped up above the height of the wall?
- Any additional surcharge loading for example a vehicle on a retained earth bank.
The tables show the panel types required for various stored/retained materials at a variety of heights. If the product you are retaining/storing is not listed please contact us for advice.
