Total Tank Terminal Construction


Verwater is the right partner for total terminal construction. With six complementary divisions the company is able to deliver complete storage plants.

Verwater’s divisions

The engineering division focuses on the design and engineering of safe and functional storage tanks. For the design and engineering of piping, tanks or other structures the latest technology is used. 3D modeling and complex stress calculations ensure a safe and efficient construction process at any time.

The division for tank construction provides durable solutions to occurring problems such as leakages or foundation settlement. With Verwater’s unique jacking system the company is able to life and move tanks of all sizes.

The construction of tank pits, leakage detection systems and infrastructural works on plants is the responsibility of Verwater’s civil department. Highly skilled employees with a vast amount of experience carry out complex measurements with the latest software programs.

An important division of Verwater that makes sure the tank and its surrounding infrastructure meet all requirements.

The tank construction department is responsible for the actual erection of storage tanks. Apart from these tanks the division also builds roof tops of any type and size. In its own workshop Verwater constructs prefabricated pressure vessels and small tank that can easily be installed on site.

The piping division specializes in engineering, manufacturing and constructing piping installations. Verwater’s piping department uses the highest quality of materials such as GRE, steel or PE pipes. These pipes are prefabricated in Vermater’s workshop and easily installed on site.

P.C.C. Conserveringswerken, Verwater’s coating division, finishes the job with the application of different layers of professional coating on the tanks. The combination of experienced tanks. The combination of experienced professionals and the latest equipment ensures a sustainable solution to any surface problem.

All of these disciplines are utilized worldwide. With offices around the globe Verwater really put its mark on the industry. From East to West, Verwater is recognized as a skilful and reliable partner.

Total Tank Maintenance

In tank maintenance Verwater plays a key role . The importance of well maintained tanks is growing steadily due to increasing safety and environmental requirements, higher quality standards as well as more economical use of tanks. The experience of Verwater in every aspect of storage tanks results in the most beneficial maintenance methods. Verwater offers a complete package for every total tank maintenance project, by applying the most modern techniques in jacking, shotblasting & painting, soil cleaning, repair of tankbottoms, mechanical work and high pressure water cutting.

Jacking works

Tank jacking is an indispensable specialism that facilitates a range of works varying from mechanical tank repairs to complete tank refurbishments. Thousands of tanks have been successfully jacked and repaired thanks to Verwater’s unique jacking methods. No matter what size or type, there is a safe jacking method for every tank.

Foundation and maintenance

Steel storage tanks as used on refineries and storage facilities for the storage of liquids are rarely constructed on piled foundations made of sand, crushed stone or a combination of both. If the sub soil is weak and easily compressed settlement of the foundation under the tank may occur. These settlements can be evenly or unevenly. If it becomes excessive problems may arise with the floating roof, the bottom and the pipes to and from the tank. If the tank settles below ground level corrosion may occur as a result of contact with water. In each of the above cases Verwater is able to reinstate the foundation to an acceptable.


The high pressure water cutting and blasting techniques are getting more common in the petro chemical industries. This method meets the demands of higher safety requirements and more stringent laws for the employment conditions. Where traditional techniques are no more applicable because of fire – and explosion hazards, hydrocutting is a safe solution to demolish old tank bottoms.


Each type of tank requires a different technical approach. Extensive experience combined with the latest computing methods results in the safest, most efficient technical solutions.

All designs and analysis comply with international standards for tank construction and repair. Tank and repair design is an in –house activity which contributes to high quality projects. Also design of piping with modern tools such as 3D modeling is part of Verwater’s services. National and international requirements are implemented in our designs and repairs. In depth knowledge (Tanknology) of these codes results in optimum designs.

The engineering department offers the following services:

  • Feasibility studies with the client
  • Development of jacking,lifting and transport plans
  • Design of inner support structures
  • Design of new tanks
  • Design of piping
  • Dimension and integrity control

The repair of tanks , in combination with tank lifting , requires extensive analysis in order to work safely .Final Element Method (FEM) stress calculations are made in computer simulations.

Survey reports are generated , showing factual and visually that repair systems stay within limits.

One of the storage tanks . Not only in tank design but also in civil works and all tank related works. Employees working more than 20yrars in this field are available for advice at any time.

Civil Works

The range of works carried out by Verwater includes the construction of complete tank pits. The company has wide experience regarding liquid tight tank pits that comply with environmental regulations. Its work may involve new construction or the rehabilitation of existing tank pits and is integrally linked with leak detection systems In addition to civil works inside the tank pit Verwater also undertakes total infrastructural works on plants.


Part of the routine of maintenance works is taking measurements to determine deflections on the tank shell or tank shell or tank bottom. These deflections can occur as a result of soil settlements. Three types of surveys are made to determine whether the tank meets the requirements; a horizontal survey of the tank shell, a horizontal survey of the tank shell, a tank bottom level survey and an out of roundness survey. To process these surveys Verwater developed special software programs that display the results both visually and numerically.

Foundation works

The Civil Works department of Verwater of Verwater specializes in tank foundation construction, construction and concrete works. A total package that consists of soil investigation and the installation of drainage, sewerage, pipe tracks, bundwalls, liquid separators and sand trap pits. To carry out maintenance on existing tank foundations Verwater gets underneath the tank after it has been jacked. A special job, but with highly skilled personnel and special equipment Verwater ensures a quick, safe and effective repair of the tank foundation.

Soil protection

Verwater offers a wide range of soil protection products that comply with the environmental regulations known as secondary containment. HDPE-liners are often placed under storage tanks to protect the subsoil. This material offers good chemical resistance and also has an interesting price quality ratio. Besides HDPE – liners Verwater installs other types of containment applications depending on the resistance against the stored product. The application of mineral layers are part of our package.

Concrete constructions

Concrete constructions are an in- house expertise of Verwater. Specifically foundation works for tanks and pump pits, floors, walls, column bases and piling works. This division offers sustainable solutions for pilling and foundation works.


In the field of maintenance tank jacking is a specialism which cannot be missed , as it gives opportunities for mechanical tank repairs up to complete tank refurbishments. Thousands of hanks have safely been jacked and repaired with the Verwatwe Tanknology , showing the reliability of the system .No matter what size or type , there is a hacking method available for every tank.
Different jacking methods:

  • Jacking entire tank or partial jacking
  • Sequential jacking or one –stage jacking

Reasons for tank jacking

There are a number of reasons to why tanks need to be lifted . A common reason is settlement. Verwater’s tank jacking technique makes restoring the original levels of the tank a simple job. To carry out repairs on foundations the treatment of leakages jacking is the most effective way to get underneath the tank.
