Product

Back to top

InfraCrete® is a mineral additive. In combination with Portland cement, it makes any type of soil more stable, frost-resistant and durable.

InfraCrete® consists of alkaline and alkaline earth elements, in other words complex mineral compounds. It is produced using quality raw materials from Germany.

InfraCrete® is a dry powder. It is easy to use the product and measure the right quantity precisely.

Soil that has been stabilised with cement and the additive InfraCrete® is several times more stable than standard base courses or layers that have been reinforced with cement or lime only. Base courses made with InfraCrete® are fully resistant to frost, salt and acid. They are protected from the alkali-silica reaction (“concrete cancer”) and harmful sulfate attack.

Cement stabilisation with InfraCrete® is a standard process involving either soil stabilisation or the construction of a hydraulically bound layer (HBL). These are standardised processes widespread in Germany and many other countries. The use of the mineral additive InfraCrete® improves their effects in multiple ways.

InfraCrete® and its predecessor products have been available since 1995.

InfraCrete® is exclusively produced in Germany.

InfraCrete GmbH with registered offices in Zollikon, Zurich Area, Switzerland, is the world’s only producer of InfraCrete®.

Benefits

Back to top

Base courses constructed with InfraCrete® are multiple times more stable and considerably more durable than conventionally built base courses. For the construction of conventional base courses, it is necessary to excavate and dispose of the existing soil in adherence to the latest environmental regulations. To construct the mineral base course, filler material must be bought. Cement stabilisation with InfraCrete®, on the other hand, only requires cement and InfraCrete®. The existing ground material does not need to be excavated. This saves both time and money.

Base courses built with InfraCrete® are considerably more stable, durable and resistant. InfraCrete® courses are fully frost-proof and resistant to water, salt and acid. They protect the soil cement from damage and destruction by preventing sulfate attack and concrete cancer. Overall, InfraCrete® courses stay intact for much longer. They require less maintenance during their calculated lifetime. By using InfraCrete®, you can use less cement while achieving the same stability.

There is another major advantage: using InfraCrete® reduces the risk of shrinkage cracks, which considerably increases the lifetime of the course. You do not need any additional chemical additives to prevent shrinkage. InfraCrete® also immobilises environmentally harmful contaminants in the soil (e.g., PAH, heavy metals).

There are no restrictions on your choice of wearing course. You can use asphalt, cobblestone or chipseal courses. Alternatively, you can choose a natural surface without a wearing course.

The wearing courses can be considerably thinner than those needed for conventionally constructed base courses. A thin layer of asphalt (4–6 cm instead of 12–16 cm) or a chipseal layer (single or double saturation) is sufficient. Thick layers of asphalt or cobblestone are technically unnecessary.

The materials available on the construction site are used very sparingly, which saves money. You do not need to excavate the existing soil, transport and dispose of the excavated material in adherence to environmental regulations, or establish a new mineral base course using filler materials that are purchased or taken from the construction site.

Many tasks required for the construction of conventional base courses become unnecessary. This saves approximately 40% of the time required by conventional processes.

InfraCrete® allows you to build extremely stable, durable and resistant wearing courses. They are immune to frost, can be constructed quickly and easily in many geographical and climate conditions and are suitable for many different applications. The use of InfraCrete® ensures low construction costs and times, durable results that are extremely long-lived and low on maintenance, and a considerable decrease in maintenance costs. InfraCrete® reduces the total costs of ownership throughout the lifetime of the final product significantly without compromising on its quality.

Independent laboratories have found that InfraCrete® is more effective and economical than competitor products.

Application

Back to top

For soil stabilisation or the construction of a hydraulically bound layer (HBL), InfraCrete® is tilled into the existing soil, compacted and levelled.

The required amount of binder (= mixture of InfraCrete® and cement) varies for each individual case. The exact formula can be determined in a laboratory. On average, coarse-grained soil types require between 4% and 6%, mixed-grained soil types between 6% and 8%, and fine-grained soil types between 8% and 10% of the dry soil weight.

The special binder always consists of 98 m% cement (Portland cement, type CEM I 32.5 or 42.5) and 2 m% InfraCrete®.

Every soil stabilisation process (using lime, cement or cement plus an additive) requires special machines. You need a spreader that applies the binder in the exact amount needed and a tiller that evenly tills the binder into the soil. In addition, you need standard machines as used by any road construction company: a grader, rubber-wheeled roller and smooth roller.

Various standards, data sheets and other regulations constitute the rules governing soil stabilisation and hydraulically bound layers (HBL). They ensure the construction of an even, high-quality product. In Germany, these construction frameworks are especially found in the following publications: “Merkblatt über Bodenverfestigung und Bodenverbesserungen mit Bindemittel”; ZTV E - StB 09; RStO 12; TP Beton-StB 10; TB BF-StB; den ZTV Beton-StB 07; DIN EN 206-1; DIN 1045-2; DIN EN 13282-(1-3); DIN EN 459-1; DIN EN 197-1; DIN EN 1164-10.

Purchase

InfraCrete® is available in all European countries and many non-European countries.

Yes. There are officially licensed InfraCrete® distribution partners in many countries. In countries without a partner, you can buy the product directly from InfraCrete GmbH.

InfraCrete® is produced exclusively by InfraCrete GmbH. It is sold by InfraCrete GmbH and selected licensed distribution partners. Unfortunately, third-party products are sometimes illegally branded InfraCrete® and offered for sale. Companies pretend to have a legal relationship with InfraCrete GmbH in order to profit from the strong, established InfraCrete® brand. Please do not hesitate to contact us. We will tell you if you have been offered a counterfeit product.

InfraCrete GmbH and its licensed distribution partners only sell the mineral additive InfraCrete®. The transport of a premixed product consisting of 98 m% cement and 2 m% additive across longer distances is not economically viable. Alternatively, we can deliver the additive directly to a cement plant near you for the production of a premixture. Please contact us to discuss this option.

InfraCrete® comes in palletised Big Bags with a net weight of 950 kg. Please contact us if you wish to order our product in another format, e.g. in bags or as a bulk purchase.

Yes. Regardless of your preferred container, the general minimum order volume is a pallet with a net weight of 1,000 kg.

Yes. We will be happy to provide you with a free, non-binding sample in a standard laboratory quantity. You can use it to run your own laboratory tests.

Please get in touch for our current prices and an individual offer for your construction project.

Yes. Our quoted prices include delivery to the construction site or another destination. They are exclusive of VAT and any customs fees, import taxes, etc.

You will have the statutory warranty rights governing our liability for defects.

InfraCrete GmbH cannot offer a warranty for your construction project, as the additive InfraCrete® is only one of many construction materials used to implement your project. As a product manufacturer, InfraCrete GmbH has no influence on the correct application of its product nor on the flawless implementation of the entire construction project.
