Sealing of silage clamps in JGS plants (animal faeces, slurry, manure, silage juice) with AgrarElast
Due to new legal environmental regulations, especially the regulation AwSV (Ordinance on Installations for the Handling of Substances Hazardous to Water, effective since August 1st, 2017), silage clamps must be specially sealed.
For the reconstruction and new construction of plants to store and fill animal faeces, slurry, manure and silage juice (JGS plants) – silage clamps, fodder fermenting silos, and storage plates for solid manure as well as biogas plants, it is only allowed to use construction products which have the technical construction approvals.
In order to meet the high requirements for permanent sealing of JGS plants, the joint sealant AgrarElast is subject to regular product monitoring and material tests. AgrarElast is also a joint sealing system that is technically approved by the German DIBt (Deutsches Institut für Bautechnik) with the number Z 74.62-176.
The product, developed by BT can be used reliably for the sealing of joints in JGS and biogas plants. AgrarElast is used to seal microbiologically and acid contaminated joints for areas with composting and fermentation processes. With this system, silos, storage, tanks, storage plates for solid manure made of concrete and asphalt can be sealed. The system is suitable for expansion joints and is characterised by its high temperature resistance.
AgrarElast consists of a system, the AgrarElast itself for sealing joints and the primers A (for asphalt) and B (for Beton – concrete). Primer A is suitable for asphalt, asphalt concrete and bitumen. This product is a set of the components A and B. Primer B is suitable for concrete, metal, and glass.
With AgrarElast joint areas between concrete and asphalt can be sealed as well as expansion joints. For the pretreatment it needs the appropriate primers.
All advantages of AgrarElast:
- Sealing of joints between concrete – concrete, asphalt – concrete and asphalt – asphalt
- Can be trafficked
- Tolerates deformations of 12,5 %
- Very high temperature resistance compared to sealants based on PU and bitumen
- Weather and UV resistance
- Simple and reliable processing
- Stable with only low shrinkage
- General building approval from the German DIBt (Deutsches Institut für Bautechnik)
- Solvent-free, isocyanate-free
For a reliable application please contact the BT specialists. They are at your disposal for consulting and instructions.
AgrarElast is suitable for sealing of storage and filling systems with substances hazardous to water e.g. in:
- JGS (Animal faeces, slurry, manure, silage juice) and biogas plants
- Storage plates for solid manure
- Fodder fermenting silos
- Silage clamps
- Effluent plants
The AgrarElast joint sealing system has the approval of the German DIBt (Deutsches Institut für Bautechnik, Z-74-62-176) and has therefore all necessary certification for these applications.
- Sealant for microbiologically contaminated joints
- For areas with composting and fermentation
- For joints that come in contact with acids

Primer A (sphalt) is a 2-component epoxy primer for pretreating of bituminous substrate for sealing joints with AgrarElast. As a pretreatment agent for asphalt surfaces, it is part of the technically approved AgrarElast sealing system (approval Z 74.62-176).
Primer B(beton – concrete) is a 1-component primer for pretreating of different substrates while using AgrarElast sealant. As a pretreatment agent of concrete surfaces it is part of the technically approved AgrarElast joint sealing system (approval Z 74.62-176).
Please adhere to the danger and safety instructions on the safety data sheets of AgrarElast and primers.
In addition to AgrarElast, BT innovation offers a wide range of products for the permanent joint sealing of prefabricated concrete and in-situ concrete components in agriculture or against pressing water. Only part of the work on JGS and biogas plants requires building products with DIBt approval.
AgrarElast: joint sealant approved by the German DIBt since June 2019 for JGS and biogas plants.
InnoElast® type 2: approved joint sealant for joints between concrete components, with which subsequent sealing is possible up to a water depth of 4.8 m.
SynkoElast®:approved construction joint tape for in-situ concrete, with which sealing is possible up to a water depth of 20 m. In combination with SynkoElast® crack profiles it is safe to manufacture closed seals in cast-in-situ construction. We already have applied for accreditation for JGS and biogas plants by the German DIBt (Application No. II 71-1.74.51-67/18).
RubberElast®: approved joint tape for a fast and reliable sealing even of complex precast concrete joints up to 5 m water depths. We already have applied for accreditation for JGS and biogas plants by the German DIBt (Application No. II 71-1.74.51-72/18).
MultiElast: a new approved joint tape for precast concrete elements and in-situ concrete with which precast elements can be sealed up to a water depth of 10 m.
ProElast®-System: approved joint sealing system made of film and film adhesive for waterproof concrete, ideal for a subsequent sealing up to a water depth of 20 m.
