An Innovative Approach for Taming Highly Compressible Soils

Wick Drains, often referred to as Prefabricated Vertical Drains or Vertical Drains, is a technique in which artificial drainage paths or vertical drains are installed into soft and compressible soils. These drainage paths take pore water out of the existing soils in order for it to consolidate much faster over a shorter period of time.

  • Accelerates soil consolidation
  • Can be installed underwater
  • Very economical approach
  • Rapid installation: shorter timelines
  • Soft soils 
  • Silty soils 
  • Clay soils 
  • Treat soils up to 40m deep 

The installation of Wick Drains is done through a specially constructed mast with a steel mandrel attached to an excavator to push a prefabricated vertical drain to the required depth on a predetermined grid pattern. This increases the apparent mass permeability of the soft soils and therefore reduces the overall consolidation time. It is often used in combination with temporary surcharge fill to expedite the primary consolidation as well as induce several decades of secondary consolidation (creep) settlement. 

How it Works

Prefabricated Wick Drains are designed to work very effectively under extreme settlement conditions. Prefabricated drains are comprised of corrugated plastic, covered in geotextile that acts as a filter to minimize any clogging that may occur. There are several kinds of prefabricated drains, both round and flat types, as well as various sizes. Networks of Wick Drains are designed according to the type of ground, and the degree of consolidation needed. This is one of the best solutions for accelerating soil consolidation.

“It was a pleasure to work with the Menard Canada team. Our high-rise development was challenged by unsuitable fill, high groundwater conditions, and adjacent historic structures. The installation of Menard’s ground improvement solution was executed within the allotted budget, schedule, and without any impact to the adjacent structures.”

Nicholas Schady, Superintendent, SKYGRiD Construction Inc.

“We have worked with Menard to provide a Design- Build proposal for many projects that shared the trait of having poor soil conditions. Menard provided professional assistance and managed the soil improvements without issue. The cost savings, time savings, and ease of construction were all realized. We would strongly recommend them for all our future projects.”

Raymond Van Groll, M.Sc. (Eng)| P.Eng. | Managing Partner, ATKINS + VAN GROLL

“Their expertise offered us complete solutions, including engineering and construction. From a simple geotechnical study, they can validate possible and alternative methods in a very short time. Being very available and creative, they have become a reference for our projects that require a more advanced geotechnical expertise.”

Karine Bourque, General Manager, Ronam Constructions Inc.

“Menard was well prepared for the job, showed up with all of the equipment that was needed and started right away. There were some challenges, and extra equipment was required, but Menard got it to the site quickly. The Menard team was good at reporting progress and challenges.”

Richard Gagné, P.Eng., Project Manager, Pembina Pipeline Corporation

“Generally quite impressed with the work Menard did. The process itself is simple and effective. The project setup, coordination and installation were straightforward. The field staff were easy to work with and were accommodating with other enabling site works.”

Radu Grumeza, P.Eng | LEED Green Associate | Assistant Construction Manager, CANA Group of Companies

“It’s been an absolute pleasure working with Menard. From the first day you arrived, we noticed the professionalism and preparation that was put in to execute this job well. You’ve allowed us to get one month ahead of schedule by starting two weeks early and finishing two weeks early.”

Zain Jessani, P.Eng. | Project Engineer, Aecon Construction and Materials Limited (ACML)

“Menard did an excellent job installing the stone columns for us in extremely challenging ground conditions; it was much appreciated!”

Richard Gagné, P.Eng., Project Manager, Pembina Pipeline Corporation

“The Controlled Modulus Column method avoided the impacts of deep shoring and dewatering while limiting the volume of excess soil generated on our site. All of this combined to simplify our foundation construction and get our project out of the ground.”

Nicholas Schady, Superintendent, SKYGRiD Construction Inc.

“Menard turned up on site as expected and worked without interruption to complete their scope. We are very pleased with Menard’s performance, and they will be our first contact for future projects requiring soil improvement.”

John Gregory, P.Eng | Construction Manager, Ark Construction LTD.

“As a general contractor, we often have to find efficient and economical solutions when soil quality is an issue in a project. On many occasions, Menard’s soil improvement solutions have significantly reduced the cost of a project. Whether it is through dynamic compaction or Vibro replacement, we have often been able to avoid pile foundations, thus reducing the budget and the schedule. In addition, Menard’s soil improvement solutions allow our clients greater flexibility in the future modifications they wish to make to their building.”

Karine Bourque, General Manager, Ronam Constructions Inc.

“The Menard team went out of their way to make the process both pleasant and efficient and wouldn’t have any reservations about using Menard in the future.”

Nicholas Schady, Superintendent, SKYGRiD Construction Inc.

“We contracted Menard Canada for the ground improvement works under two residential buildings and an amenity building in Chatham, Ontario. Their team worked with the Structural and Geotechnical Consultants during the design phase to find a solution to the local ground conditions – which proved to be very beneficial for the development of this site and the project as a whole. They then carried out the designed ground improvements on site; our team appreciated Menard Canada’s professionalism and proactivity. After the completion of the work, the Menard Canada team was available for questions and always provided feedback right away. Menard Canada would definitely be our first choice for any ground improvement on our next projects.”
