Tobermore’s Secura retaining wall products provide architects, engineers, contractors and housebuilders with cost-effective solutions for all types and sizes of retaining wall projects. This retaining walling system has numerous benefits, especially when compared to standard concrete retaining walls.
Fast, easy mortar-free installation
Secura retaining walls are built up using a simple, mortar-free, dry method. Once the area behind the planned wall has been excavated, only a concrete foundation is required, and no wet trades are needed for construction of the wall. There are no mortar drying times to delay installation, meaning that constant progress can be achieved.
Secura retaining walls can be installed by an unskilled labour force, saving time and money during construction. The placement of the blocks is simple, with a nib holding them in place. and rapid progress can be made.

Retaining Wall Design Service and Technical Support
Tobermore can provide standard cross sections for use at appraisal stage and we also work with a UK based geotechnical and civil engineering partner who specialise in segmental retaining wall design. They can provide a project specific preliminary design for appraisal or a formal PI design if required. As part of their service they will provide full specification details for the geogrid and the backfill material required for a successful scheme.

Range of sizes for all scales of project
The breadth of products in the Secura range mean that different scales of project can be accommodated. There are products for gravity retaining walls, reinforced soil walls, and retaining walls constructed with concrete backfill.
Gravity retaining walls up to 960mm
Gravity retaining walls depend only on their own weight to resist pressures from the soil behind them. They are ideal for retaining walls up to 960mm high. They are used for smaller domestic walls, terraced walls or raised planting areas.
Secura Lite is the best product for these situations and is available in three block sizes in one pack.
Reinforced retaining walls over 1.2m
Retaining walls should be reinforced in applications above 1.2m metres high and they can be built up to 9m high. The reinforcement is most often provided by a mesh geogrid, which is laid between the blocks and covered with backfill which is then compacted.
Retaining walls with concrete backfill
For areas where only a small backfill area is available, concrete is poured into the excavated space behind the wall. This fill then acts as a mass gravity wall.
This method can be used in areas where there is up to almost 50% less space available behind the retaining wall, compared with geogrid-reinforced applications. It is a slightly more expensive option, so is only specified where space is limited.
Secura Grand blocks are used for higher walls. They are ideally suited to larger landscaping schemes found on housing developments, roads, commercial property etc. Download our Secura Retaining Walls design guide for more information.
Attractive, rugged appearance
Secura offers the same stability as standard concrete retaining walls but with a much more pleasing finish. The rustic surface texture gives the appearance of aged, natural stone.
Three attractive blended colours are available: Heather, Bracken and Slate. The natural variation of colour provides a softer, far more attractive look than plain grey concrete.
It is suited to areas where standard concrete would be too harsh, such as housing developments, rural areas or higher prestige urban developments.
More efficient use of space
When built up, Secura retaining walls gradually slope back, opening up areas and giving a greater sense of space compared with claustrophobic vertical concrete retaining walls. It also offers the facility to create an extra outdoor space by cutting into the slope and flattening out the area.
Creating curved retaining walls
Secura retaining walls can be easily designed and built up into curves. Design and installation guidelines are available. Contact us for more information.
For reinforced soil walls, the geogrid should be laid in strips around the curved wall on the first course, ensuring that the principal reinforcement direction is perpendicular to the wall, ensuring maximum strength. On the second course, alternate the placing of the geogrid, so that the whole area is covered as the wall rises.
Creating retaining walls with 90 degree corners
You can create 90 degree corners using Secura Grand retaining wall blocks. There are two types of corner block to use when constructing internal and external corners, a left and right block. These are used alternately for each new course.
