As a specialist geotechnical contractor, Menard delivers complete design-build foundation systems using ground improvement techniques. Our solutions are creative and cost-saving alternatives to the deep foundations traditionally used to support buildings and structures.

A Comprehensive Service

As a result of the geotechnical know-how accumulated through the completion of thousands of projects, MENARD consistently provides the essentials for success: a good price, a reliable schedule, well managed construction techniques and a commitment to excellence in safety and environmental protection.

A Complete Solution

Often involved from the project conception onwards, Menard works closely with clients in analyzing their objectives. Based on the geotechnical investigation report and the description of the structures to be built, MENARD will recommend the most appropriate soil improvement technique, depending on the analysis of the soil, the structure and the environmental constraints. MENARD engineers will then produce a detailed design, and the subsequent construction will be carried out by dedicated teams based in more than 50 locations worldwide. Finally, our quality control procedures will allow us to com-plement our design and construct package with a long-term guarantee.

State of the Art Technology

Over the last 50 years, MENARD has improved and developed a complete range of innovative and sustai-nable soil improvement techniques. A fundamental objective of the company has always been to remain at the forefront of technological advances in this fi eld and to offer more effi cient, reliable and economi-cal solutions. Our leading expertise is built on our fi eld experience, our numerical modelling capabilities and the development and optimization of specialised construction equipment.

Techniques Techniques

Dynamic Compaction (DC)

Vertical Drains (VD)

Menard Vacuum (MV)

Vibro Compaction (VC)

The techniques implemented by Menard can meet the most demanding specifi cations. They fall into two categories.

Improvement without addition of material

For granular soils (sand, gravel), densifi cation is achieved by pounding (Dy-namic Compaction) or vibratory (Vibro Compaction) methods. For cohesive soils (clay, silt), the soil characteristics are improved by preloading the site with a temporary embankment; this process can be signifi cantly accelerated by installing a drainage system (Vertical Drains). The atmospheric pressure (Menard Vacuum) can also be applied instead of the load of the embank-ment to provide an accelerated isotropic consolidation.

Improvement with addition of material

These techniques consist in installing fl exible, rigid or semi-rigid vertical inclu-sions in the compressible soil layers. These inclusions are laid out following a regular grid pattern. They are either made of non-cohesive granular material (stone columns and dynamic replacement pillars) or involve the use of a bin-der (controlled modulus columns, compaction grouting, soil mixing, jet grou-ting). The resulting consolidated soil layer behaves like a composite material with improved characteristics.

Objectives :

- reduce long term differential settlements;

- guarantee the stability of high embankments with regards to circular slope failure

For transportation engineers, it is not always possible to avoid building on highly compres-sible soils. The crossing of wetlands and rivers in particular will require an important consoli-dation of the in-situ soil in order to avoid ma-jor slope failures within the future road and rail embankments.The pre-consolidation of the most compres-sible areas is crucial to prevent long term creep settlement while ensuring the infrastructure can be operated safely. The consolidated soil foundation will increase the service life of the road pavement, thus reducing life-cycle costs for the roads and railways.Approach embankments leading to bridges can produce signifi cant loads in subsurface soils, up to 20 t/m2. These specifi c critical zones will require intensive ground improve-ment to ensure proper performance.

The term Heavy Industry covers specifi c facilities such as sewage treatment plants, power plants, refi neries, petrochemical plants, storage areas, etc. These structures are often very heavy and prone to risk. Their foundations in compressible soils is a major challenge to guarantee the safe and secure performance of the plants over time. The most cost-effective foundations system of-ten requires using multiple soil improvement treatment techniques to match the variety of soil properties and load conditions.These foundation systems will:support uniform heavy loads (water, oil and gas storage tanks);support isolated loads (pipe-racks, industrial buildings, machinery);reduce total and differential settlements to wi-thin acceptable limits.

Objectives :

- ensure the self-bearing capacity and stability of the fi ll; - increase the bearing capacity;

Available lands around marine routes (sea, ri-vers) on which ports and airports are construc-ted often consist of highly compressible and saturated soils. Our techniques provide econo-mical solutions to consolidate these soils within a reduced timeframe, in order to guarantee mi-nimal residual settlements when the platforms are operational.

Ports and airports usually cover large areas of land – several hectares – and they are conse-quently often reclaimed from the sea using granular dredged materials or imported fi ll ma-terials. The challenge is to provide an economi-cal means to improve the characteristics of the large quantities of fi ll involved in the construc-tion of the platform. The primary objectives of the ground improvement works is to ensure the short-term and long-term stability of the plat-form. When required, a more intensive impro-vement can also increase the bearing capacity suffi ciently to support future facilities and buil-dings. Eventually, in seismic areas, the risk of liquefaction can be mitigated.
