Micropiles | Minipiles
CALL FOR QUOTE
Micropiles, also called Minipiles, are a preferred support system used in the stabilization of buildings, bridges, highways, and towers.
Micropiles are generally used for underpinning and retrofitting structures that are engineered using geotechnical techniques and conventional materials. They are composed of small-diameter piles that are constructed by drilling a hole, typically 4″ to 8″ inch diameter deep into the soil, then inserting a high-strength threaded bar or pipe, and filling the hole with high strength grout. The primary purpose micropiles is to support new structural foundations and underpinning of existing foundations.
For over 35 years GSI has performed reliable, top quality grouting, soil stabilization and foundation support services helping our client for (in the field of) ground improvement and foundation underpinning.
Provide structural support
Enhance mass stability
Transfer loads to competent soil layer
Micropiles are designed around the physics of skin friction
that develops between the grout/soil interface but they can also be incorporated to support end-bearing capacity when drilled into competent strata or socketed into bedrock. Soil conditions and load capacity requirements dictate hole size and depth as well as reinforcing type.
When You Might Need Micropiles
Micropiles can be used in a variety of applications. They are particularly useful when projects are launched in areas with:
- limited access
- deep foundations
- weak difficult soil conditions
They offer temporary or permanent structural underpinning and can support heavy loads in congested areas. Other uses involve mitigating foundation settlement and providing excavation support in confined spaces.
Micropiles have become a preferred method of deep foundation stabilization in tough construction conditions. Their reliability, versatility, and efficiency make them an ideal solution when faced with areas of low clearance, restricted access, or collapsing soil types.
