Embedded Retaining Walls
Contiguous Bored Pile Walls
- Discontinuous wall i.e. not watertight.
- Pile spacing = diameter +100mm.
- Installed with any bored piling equipment.
Slopes between 60° – 65°. Typically can be created with horizontal reinforcement design and installed typically of length 70% vertical height Granular stone or growing medium facing.

Sometimes no amount of decorative brickwork, timber facing or planting can prevent a retaining wall or similar structure from looking out of place and in conflict with its surroundings. Excavation in unstable slopes and poor ground can be a real problem when the maintenance of the natural beauty of parkland, landscaped gardens or in a protected green environment are major issues.
Natural reinforced earth slopes
A real benefit for natural environments, where retaining structures would either be inappropriate or too constraining, reinforced slopes offer a landscaped alternative encouraging vegetative growth and a less imposing aspect. Within months grasses and mosses grow through the synthetic mesh facing creating a fully planted out bank which gives the impression of disappearing seamlessly into the environment.
Beauty comes at a surprising price
This type of retaining system is often surprisingly economic where there is scope and space for design and installation on site.
A reinforced slope solution with ground reinforcement can be just one part of a complete package of services we supply to major construction sites across the UK; at Geoforte you can also find specialist foundation piling, retaining walls and a range of other ground stabilisation techniques expertly applied to even the most challenging ground conditions.
- We offer a variety soil nailing solutions for slope stabilisation/temporary retention works.
- Non anchored.
- Grouted Bar.
- Bauer Ductile Pipe system.
- Rock Drilled grouted bar.
- One process that could greatly enhance the transportation of chemicals through the soil is electro-osmosis.
- Electro osmosis is a under-utilised technique that has the potential to improve the foundations of existing structures in the UK.
- The largest potential benefit is the avoidance of far more disruptive underpinning operations.
- Clay is 5000 times more porous under an electrical gradient than normal.
- When an electrical potential is created a charge is forced between the electrodes.
- The anode releases cations that migrate towards the cathode along with water
- The cations chemically change the physico-chemical properties of the soil
Electrical Resistivity Imaging (ERI)
- A 2D tool to recognise tree related subsurface dessication
- Non-Invasive Tool to assess tree-induced subsidence
- By characterising seasonal subsurface moisture content distribution.
- Helps to define the architecture of the tree root system.
Grout is injected through the centre stem, then a special three – auger configuration mixes cement grout with soils in-situ.
Mixed soil/grout material attains structural strength (0.5 to 2+ Kps).
No ground beams are required, block work can be built straight off graded improved soil/grout mixture.
No vibration, no spoil.
