DIP Engineering | Unique Self - Locking Joint

• Self-locking tapered spigot end and tapered socket
• Joint strength is greater than pile’s section.
• Internal shoulder
• Double thickness socket wall
• Large driving face

Fast, easy & safe
• Self-locking joints cut costs and delays
    by eliminating welding and splicing.
• They offer a high degree of rigidity.

Each joint is cold welded
The expansion and contraction of the two tapered ends,
under high contact pressure, creates irreversible non-elastic deformation of the ductile cast iron.


Welcome to the DIP revolution!
Welcome to the DIP revolution! We invite you to review our presentation and discover this innovative, flexible, and cost effective foundation technology.
Huge Cost Savings with DIP
CMS has proven 
that DIP provides huge potential cost savings of up to 70% of the value 
of traditional precast or steel encased concrete piling.
DIP Capability and Environmental Impact
Ductile iron Piles can be driven at angles up to 45°, exponentially expanding the range of pile uses. They produce minimal ground disturbance even in close proximity to existing structures.
DIP Engineering
The Plug&Drive© DIP pile system's precision engineering consists of self locking joints,
 built for durability, consistency, strength and ease of installation.
Mobility and Adaptability
The Plug&Drive© DIP pile system's mobility and adaptability is due to compact,
 lightweight equipment and a comprehensive array of well designed accessories.
Dry Driven for Skin Friction Piles
Dry Driven for Skin Friction Piles is a technique is used with deep soft soil 
where it is impractical to find firm bedrock.
Dry Driven for End Bearing Piles
End Bearing Ductile Iron Piles are ‘Dry Driven’ into the ground until they reach practical refusal. Fast and cost effective to install in areas of bedrock or very dense, cohesive strata.
Grouted Annulus for Skin Friction Piles
Grouted Annulus for Skin Friction Piles is a simultaneous driving and grout injection method to install DIPs, creating skin friction and corrosion protection.
