Access Behind Wall
If there is insufficient clearance behind a retaining wall during construction,
it will be difficult to install the drainage system. This is often a problem for
retaining walls constructed on a boundary. In such a case, position the drainage
system before completing the stem of the retaining wall.
Installing the Appropriate Geotextile
The geotextile is a permeable textile material used with foundations, soil, rock,
earth or any other geotechnical engineering-related material as an integral part
of a project. Geotextiles are commonly used to filter groundwater, to contain and
separate soil and aggregate layers and/or to strengthen foundations and road subgrade
against shear failure under load. The specification for geotextiles requires adequate
permeability and void size to pass water, limited pore size to restrict particle
movement, and strength ensure its integrity.
Geotextiles for Filters and Drains
Geotextiles for Filters and Drains shall exhibit:
- Sufficient permeability to maximise the amount of water passing through the outer surface.
- Sufficient void size, under load, to convey the required water flow to the stormwater system.
- Pore size small enough to block fine material from entering the drainage system, without compromising the permeability requirements.
- Strength, toughness and abrasion resistance to resist damage during construction and service.
